“His feet hit the mat, and almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child.” That was Kaitlin Hill telling ABC News what happened when her three-year-old son Colton’s femur snapped during a “Toddler Time” session at a trampoline park. Like so many families in Ponder, Texas, she was told the environment was safe. Like so many, she later realized she had been sold a version of safety that didn’t exist. “We had no idea,” she said. “We would have never put our baby boy on a trampoline if we had known.”
We hear these stories in our offices every week. For over 25 years, Ralph Manginello and the team at Attorney911 have stood with families across Texas when catastrophic corporate negligence changes a life in a single second. Whether your child was injured at an Urban Air near Denton, a Sky Zone in Frisco, or on a backyard trampoline in a Ponder neighborhood, the path to recovery is the same. It requires an attorney who doesn’t just “handle” personal injury, but one who has spent decades making Fortune 500 companies like BP, Walmart, and Amazon pay for the decisions they make to put profit ahead of safety.
If you are reading this from a hospital bed at Cook Children’s in Fort Worth or Children’s Medical Center in Plano, we know the guilt you are feeling. You signed the waiver at the kiosk. You handed them the wristband. We are here to tell you: this is not your fault. The commercial trampoline park industry is a billion-dollar machine designed to move families through the door as fast as possible while minimizing their own liability. They know the standards—ASTM F2970 for parks and ASTM F381 for home use—and they choose to operate below them because it protects their margins. We lead our trampoline injury practice with the authority of 25+ years of trial experience and the insider knowledge of Lupe Peña, a member of our firm who used to defend insurance companies and recreational businesses. He knows their playbook because he helped write it. Now, he uses that knowledge to dismantle their waivers and hold them accountable.
The Reality of Trampoline Injuries in Ponder and North Texas
Ponder is a community where families prioritize active lifestyles. Between Ponder ISD athletics, cheerleading groups traveling to competition centers in Dallas, and the backyard trampolines lining our suburban streets, children are airborne every day. But the data on these activities is staggering. Approximately 1.6% of all pediatric emergency department trauma visits in the United States are now trampoline-related, according to the American Journal of Roentgenology.
Nationally, more than 300,000 trampoline-related ER visits occur annually. In Ponder, where families often drive down FM 156 to visit massive facilities like Altitude Trampoline Park or Urban Air, those risks are amplified by the sheer throughput of these parks. A 2024 study published in the journal Pediatrics (Teague et al.) tracked over 13,000 injuries and found that foam pits carry an injury rate of 1.91 per 1,000 jumper-hours. High-performance jumping areas are even more dangerous, at 2.11 per 1,000 hours.
These aren’t just “scraped knees” or “minor sprains.” We represent the families facing permanent cervical spinal cord injuries, traumatic brain injuries (TBI), and Salter-Harris growth plate fractures that will require a decade of orthopedic monitoring. We’ve seen what happens when the system fails—and we are built for the fight that follows.
Why Ponder Families Choose Attorney911
When a catastrophic injury occurs, you aren’t just fighting a local park operator. You are fighting a layered corporate tower. Effective January 1, 2023, CircusTrix LLC was renamed Sky Zone, Inc., now backed by Palladium Equity Partners and parenting the Sky Zone, DEFY, and Rockin’ Jump brands. Similarly, Unleashed Brands (the parent of Urban Air) was acquired by Seidler Equity Partners in 2023.
These parent conglomerates hire the same caliber of national defense firms that Ralph Manginello has beaten in litigation involving the BP Texas City refinery explosion. They bring an army of lawyers and a stack of kiosk waivers. We bring a proven track record.
- Total Fearlessness Against Corporate Giants: We have gone toe-to-toe with the world’s largest corporations. The private equity sponsors behind national jump park chains don’t intimidate us.
- Inside Knowledge of Insurance Defense: Lupe Peña’s background as a former defense attorney gives our clients a “waiver defeat edge.” He knows exactly which clauses in Texas are full of holes and which arguments make insurance adjusters escalate a claim for settlement.
- Academic and Physiological Authority: We are currently litigating a $10 million lawsuit against a major university involving rhabdomyolysis and acute kidney failure. This is the same muscle-breakdown medical emergency we see in children who jump for extended periods in hot, indoor trampoline parks. We know the doctors, the science, and the experts required to win.
- Hablamos Español: Lupe Peña habla con usted directamente—sin intérpretes. Representamos a las familias hispanohablantes de Ponder con el respeto y la agresividad que sus casos merecen.
- 1-888-ATTY-911: We are available 24/7. When an accident happens on a Saturday night at a birthday party, you need our spoliation letter out by Monday morning before the park overwrites the surveillance footage.
Understanding the “Double-Bounce” and Other Mechanisms of Harm
In trampoline litigation, the mechanism of injury is the bridge to proving negligence. The defense will always claim your child “landed wrong” or “assumed the risk.” We use biomechanical engineering and industry standards to show the truth.
The Physics of the Double-Bounce
This is the signature trampoline park injury. It occurs when a heavier jumper (often an adult or older teen) lands on the trampoline bed just as a smaller child is pushing off. The energy transfer multiplies the child’s launch force by up to 4x. The child isn’t jumping anymore; they have become a projectile. ASTM F2970 requires parks to separate jumpers by age and weight for this exact reason. When a Ponder family visits a park and sees a 200-pound man on the same court as an 80-pound child, they are witnessing a violation of the industry’s own safety standard.
Foam Pit Failures
Foam pits look soft, but they are often deceptive. If the foam cubes are compressed or the pit is too shallow—a direct violation of ASTM F2970 and the international EN ISO 23659:2022 standard—the jumper hits the hard floor beneath. This was the mechanism in the 2012 death of Ty Thomasson in Arizona, which led to “Ty’s Law.” It is also how quadriplegia occurs during “simple” backflips.
Harness and Zipline Failures
At many “adventure” parks in North Texas, attractions like the “Sky Rider” zipline or climbing walls are marketed as thrill rides. In the Ispahani case in Sugar Land, a harness was never properly attached. In the 2019 death of Matthew Lu at an Altitude park in North Carolina, the park publicly admitted “human error” and removed the climbing wall. These admissions are gold for our litigation strategy. If a harness wasn’t checked, it isn’t an accident—it’s a staffing failure.
The Waiver Architecture: Why You Can Still Sue in Texas
The most common thing a Ponder parent says to us is: “I’d call you, but I signed that waiver on the iPad at the front desk.”
In Texas, a waiver is a piece of evidence, not a wall. We attack the waiver on three primary fronts:
- The Munoz Rule: Under Munoz v. II Jaz Inc., a parent in Texas generally cannot sign away a minor child’s personal injury claim in advance. While the waiver might affect your own claims as a parent, your child’s right to be made whole is protected by the court.
- Gross Negligence Carve-Out: Texas law (Transportation Insurance Co. v. Moriel) holds that you cannot waive claims for gross negligence. If the park knew a trampoline was torn and left it in service anyway—like in the $11.485 million Cosmic Jump verdict—the jury can, and will, ignore the waiver.
- The Dresser Fair Notice Doctrine: Under Dresser Industries v. Page Petroleum, a waiver is only enforceable if it is “conspicuous.” If the release was buried in a long click-through screen or didn’t use the specific word “negligence” in bold, large font, it may be void.
One of our attorneys used to write these waivers. We know exactly where the seams are. We know how to take them apart.
Catastrophic Pediatric Injuries: Beyond the Emergency Room
A trampoline injury at age seven is not the same as one at age forty. Children’s bodies are biomechanically distinct. We focus heavily on “Salter-Harris” growth plate fractures. Since the growth plate is made of cartilage, it is often weaker than the surrounding tissue. If it is crushed or fractured, the bone may stop growing or grow crooked.
A child in Ponder who suffers this at age eight might not see the full damage until they hit their growth spurt at age fourteen. If your lawyer settles your case for the “ER bills plus a little extra” today, who pays for the corrective surgeries your child will need six years from now?
We build Life Care Plans. We work with pediatric orthopedic surgeons, life-care planners, and forensic economists to project the true cost of your child’s injury through skeletal maturity and beyond. As client Glenda Walker said, “They fought for me to get every dime I deserved.” We bring that same tenacity to your child’s future.
48-Hour Evidence Preservation: The Clock is Ticking
Trampoline parks are notorious for evidence disappearing. Surveillance DVR systems at local parks are often set to overwrite every 7, 14, or 30 days. Incident reports get “revised” once a corporate risk manager sees the severity of an injury.
We stop the clock. Within 24 hours of being hired, our firm sends a certified Spoliation Letter to the park’s operator, franchisee, and franchisor (such as UATP Management for Urban Air or Sky Zone Franchising). We demand the preservation of:
- All surveillance footage from all cameras (not just the one they choose to show you).
- Metadata for incident reports (to see what was edited and when).
- Shift logs to see if they were understaffed (violating ASTM F2970 ratio requirements).
- Training records for the teenage monitors on duty.
- Kiosk audit trails to verify waiver execution.
As client Angel Walle noted, “They solved in a couple of months what others did nothing about in two years.” That speed comes from our pre-drafted discovery scaffolds thatเรา deploy the moment you call.
Rhabdomyolysis: The Silent Threat of the 2-Hour Jump
If your child visited a trampoline park in the Ponder area and later complained of severe muscle pain, listlessness, or “cola-colored” urine, you must get to an ER immediately. This is Exertional Rhabdomyolysis. It occurs when excessive jumping causes muscle tissue to break down and release myoglobin into the blood, which can lead to acute kidney failure.
Indoor parks are often hot and poorly ventilated. When a park sells “All-Day Jump” passes without enforcing hydration breaks, they are creating a biological hazard. We are one of the few firms in the country with an active $10 million lawsuit specifically involving rhabdomyolysis physiology. We have the medical experts and the institutional accountability theories ready to go.
Frequently Asked Questions for Ponder Parents
Can I sue if I signed a waiver?
Yes. As established by the Cosmic Jump $11.485 million verdict in Harris County, gross negligence defeats a waiver. Additionally, under the Munoz rule, parental waivers are often unenforceable against a minor’s own claim in Texas. We will review your specific waiver and the circumstances of the injury to find the attack vector that works.
How much is my trampoline injury case worth?
It depends on the severity. Catastrophic spinal cord injury verdicts have reached the $15 million range (Damion Collins v. Urban Air). Serious pediatric fractures with growth-plate damage often anchor in the $500,000 to $2 million range. We don’t guess—we use data and experts to calculate every dime of future medical care and lost earning capacity.
The park manager said it was a “freak accident.” Does that mean I can’t sue?
“Freak accident” is an industry euphemism for “unforeseen.” But injuries at these parks are entirely foreseeable. The AAP has been warning about them since 1999. If the park violated staff-to-jumper ratios or had torn equipment, it’s not an accident—it’s negligence.
How long do I have to sue a trampoline park in Texas?
In Texas, the statute of limitations for personal injury is 2 years. For minors, the clock is typically “tolled” until they turn 18, meaning they have until age 20. However, waiting is a mistake. Witness memories fade and surveillance video is deleted within weeks. Call 1-888-ATTY-911 now so we can preserve the evidence today.
What about a neighbor’s backyard trampoline?
If your child was injured at a neighbor’s house in Ponder, the Attractive Nuisance doctrine may apply. This holds homeowners liable when they have dangerous equipment that attracts children. We look at every insurance layer, including homeowners’ policies and any personal umbrellas.
Liable Parties: Who Actually Pays?
We don’t just sue the local guy. We trace the money. The operator LLC is usually underinsured. We go upstream to:
- The Franchisor: (e.g., Sky Zone Franchising LLC or Urban Air Franchise Holdings).
- The Corporate Parent: (e.g., Sky Zone, Inc. / Unleashed Brands).
- The PE Sponsor: (e.g., Palladium Equity Partners or Seidler Equity Partners).
- The Manufacturer: (e.g., Jumpking, Skywalker, or UA Attractions LLC).
One company told client Donald Wilcox they would not accept his case. “Then I got a call from Manginello,” he said. “I got a call to come pick up this handsome check.” We take the difficult cases and pierce the corporate shields that other firms avoid.
Imagine the Strategy Ponder Families Deserve
Imagine a Saturday at the Sky Zone in Frisco or the Altitude in Dallas. The court is packed with 60 kids under the supervision of two sixteen-year-olds on their phones. Your son lands on a mat that was noted as “torn” on an inspection log three weeks ago. He falls through onto the unpadded concrete subfloor.
The park’s first move isn’t to help; it’s to hide. They point to the waiver. They “misplace” the video. They tell you it’s an inherent risk.
Now imagine your response: calling 1-888-ATTY-911. Within an hour, Ralph Manginello is coordinating the investigation. Within 24 hours, our spoliation demand is on the franchisor’s desk. We know the ASTM F2970 sections they violated. We know the 2024 Teague study that proves their foam pit is a hazard. We know where the insurance towers are layered.
You pay us nothing unless we win. We advance every cost for the biomechanists and surgeons. Your child’s recovery becomes our mission. 1-888-ATTY-911. Hablamos Español. The case starts today.
Frequently Asked Questions
Can I sue if I signed a waiver at a trampoline park in Ponder, TX?
Yes. Specifically in Texas, a waiver is not an automatic bar to recovery. Under the landmark $11.485 million Cosmic Jump verdict out of Harris County, if gross negligence is proven—meaning the park acted with conscious indifference to a known risk—the waiver is void. Furthermore, Texas case law under Munoz v. II Jaz Inc. establishes that parents generally cannot waive a minor child’s independent legal right to sue. We also examine the Dresser Fair Notice Doctrine to see if the waiver was conspicuous and whether it used the exact word “negligence” as required by law.
What should I do in the first 48 hours after a trampoline injury in Ponder?
- Prioritize Medical Care: Head injuries, cervical pain, or growth plate fractures require a Level 1 pediatric trauma center like Cook Children’s in Fort Worth or Children’s Medical Dallas.
- Preserve Physical Evidence: Save the wristband, the receipt, and the clothing your child was wearing.
- Capture the Scene: Take photos of the equipment, any torn mats, and the location of attendants.
- Call Attorney911 at 1-888-ATTY-911: We must send a spoliation letter immediately. Trampoline park surveillance DVRs often overwrite in just 7 to 30 days. We need to freeze that evidence before it vanishes.
Who is responsible for a trampoline injury on a neighbor’s property in Ponder?
Backyard trampoline cases follow a different legal path than commercial parks. We utilize the Attractive Nuisance doctrine, which holds homeowners responsible for hazards that attract children who cannot appreciate the danger. We investigate all insurance layers, including homeowners’ primary policies and any excess umbrella coverage. We also look at the manufacturer of the trampoline—brands like Jumpking or Skywalker—to see if a design defect or a failure to warn (violating ASTM F381) contributed to the accident.
How much can I recover for a trampoline park concussion or TBI?
Verdicts for traumatic brain injuries in trampoline parks vary, but they often reach multi-million dollar figures when long-term cognitive care is required. In Texas, we build a Life Care Plan to account for educational needs, neuropsychological monitoring, and lost future earning capacity. Because we have experience litigating against global entities like BP and Amazon, we know how to reach the multi-layered insurance towers (umbrella and excess layers) held by chains like Sky Zone, Inc. (Palladium Equity) and Unleashed Brands (Seidler Equity).
What is rhabdomyolysis and how is it related to trampoline parks?
Exertional rhabdomyolysis is a medical emergency where muscle tissue breaks down and enters the blood, potentially causing kidney failure. It is a known risk for children who jump for extended periods in hot indoor environments like those in North Texas. Because our firm actively litigates a $10 million university hazing case involving this exact pathology, we have a unique medical-litigation architecture already in place to win these cases. If your child had “cola-colored” urine or extreme muscle swelling after a visit to a park, call us at 1-888-ATTY-911.
Why do I need a lawyer with federal court experience?
Chains like Urban Air, Altitude, and Sky Zone are backed by massive private equity firms and operate across state lines. These cases often move into federal court if the headquarters are in different states. Managing Partner Ralph P. Manginello is admitted to the Southern District of Texas and has over 25 years of trial experience. You need a lawyer who isn’t intimidated by a corporate parent’s army of defense attorneys.
Do I pay anything upfront?
No. We work strictly on a contingency fee basis. This means there are no upfront costs and you pay no fee unless we win. We advance the costs for every expert your case needs—from biomechanical engineers who reconstruct the double-bounce physics to pediatric surgeons who testify about growth plate damage. Your family’s recovery fund stays intact while we fight the corporate defendants.
Are trampoline parks in Texas regulated by the state?
Surprisingly, no. Texas has no statewide trampoline park safety act. While the Texas Department of Insurance (TDI) regulates Class B inflatable attractions like indoor zip-coasters or bungee tramps, the main trampoline decks are largely unregulated. This “regulatory gap” is a strong piece of evidence in our negligence claims—the park had the chance to follow the industry’s voluntary ASTM F2970 floor, and they chose to operate below it.
Can Lupe Peña talk to my family in Spanish?
Sí. Lupe Peña es abogado asociado de nuestro bufete y habla español nativo. Él habla directamente con usted sin necesidad de intérpretes. Esto es crucial cuando se trata de casos complejos donde la barrera del idioma puede ser utilizada por las compañías de seguros. Llame al 1-888-ATTY-911 y pida hablar con Lupe.
How do I know if my child has a growth plate injury?
In pediatrics, a “broken bone” is often a Salter-Harris fracture through the growth plate. These are classic trampoline park injuries. If not documented and monitored, they can lead to one leg being shorter than the other or permanent angular deformities as the child grows. We ensure you have the right specialists to document these damages for the next decade of your child’s life.
Why the First Week Decides Your Case
The Saturday afternoon your child was injured at an Urban Air or Altitude near Ponder, TX, is already fading from the record. The park’s risk management team is working to categorize the event as “guest error.” The teen employee who was on their phone at the moment of the double-bounce might not work there in three months.
We don’t wait for them to contact you with a “friendly” offer. We send the spoliation letter. We pull the FDD Item 3 litigation history. We run the custom CPSC NEISS query. We build the case that makes them pay.
Call 1-888-ATTY-911. Ralph Manginello and Lupe Peña are ready to stand with you. Hablamos Español. No fee unless we win. The fight for your child’s future starts with one call.
Detailed Liability Analysis for Ponder Trampoline Cases
We approach every Ponder trampoline case as a forensic reconstruction. We do not accept the “freak accident” narrative because we know exactly how these parks are engineered to fail.
The 5-Layer Defendant Stack
When we file your case, we identify every layer where money is hidden. In a typical park injury, our “corporate archeology” uncovers:
- The Operator LLC: The local entity usually names on your receipt.
- The Franchisee: The multi-unit group that often owns several North Texas locations.
- The Franchisor: Entities like Sky Zone Franchising LLC or Altitude Franchise Holdings. Under the Sampson doctrine, we pierce their “independence” defense by showing they exercised actual or apparent control over the safety manuals and monitor ratios.
- The Parent Corporation: Sky Zone, Inc. (f/k/a CircusTrix) or Unleashed Brands.
- The Private Equity Sponsor: Firms like Palladium and Seidler Equity. We pull their investment committee memos in discovery to find where they approved the staff cuts that caused the injury.
Negligent Staffing & Training
Section M of our internal data show that the average court monitor is a 16-19 year old making near minimum wage with only 2-4 hours of training. In states like Washington, Sky Zone Tukwila was recently fined $68,000 for child labor violations. We use these patterns to argue that a park that won’t follow labor laws for its own teens certainly isn’t following ASTM F2970 safety rules for yours.
The Foam Pit Compaction Hazard
FOAM is not a permanent safety surface. Every time a jumper lands, the open-cell polyurethane cubes lose their “loft.” ASTM F2970 requires parks to rotate and “fluff” these cubes and replace them on a strict cadence. Parks that skip these steps to save on capex are literally letting your child land on a surface that has the impact-absorption of a thin rug over concrete. We subpoena the rotation logs—and the metadata—to find out when they last actually maintained that pit.
Catastrophic Damages: The Life Care Plan Discipline
We do not just calculate medical bills. For a Ponder family facing a permanent spinal cord injury (SCI) or a severe TBI, the bills you have today are less than 5% of the bills you will have over your child’s lifetime.
We utilize Section H.15 Pediatric Life Care Plan Architecture to capture:
- Future Special Education Costs: A pediatric TBI creates educational needs for 18+ years that public schools often cannot meet.
- Durable Medical Equipment: Replaced every 3-5 years as a child grows.
- Lost Earning Capacity: Even a “mild” cognitive regression at age nine can reduce a child’s lifetime earnings by millions.
- Tax-Adjusted Medical Cost Projections: We ensure your recovery is present-valued against Texas economic trends.
As client Donald Wilcox said, “I got a call to come pick up this handsome check.” We get there because we document more damages than the defense ever anticipates.
Final Word from Attorney911
If your family is in Ponder or anywhere in Denton County, and you are staring at a body cast or an MRI report, know that you are not alone. The system is designed to make you feel defeated by a kiosk. But the law in Texas—and the 25 years of experience Ralph Manginello brings—says otherwise.
We have stands in your shoes. We know the North Texas roads you travel down FM 156. We know the local pediatric providers. And we know exactly how to make the corporations that own these parks pay for what they’ve done.
Call 1-888-ATTY-911. 24 hours a day. Hablamos Español. We advance every cost. You pay zero unless we win. The case starts now.
Detailed Medical Taxonomy for Trampoline Injury Victims
When we communicate your child’s injury to an insurance carrier, we use the medical specificity that signals our authority. We don’t just say “broken arm”; we say “Gartland Type III supracondylar humerus fracture requiring closed reduction and percutaneous pinning (CRPP).”
Pediatric Spinal Hazards
- SCIWORA (Spinal Cord Injury Without Radiographic Abnormality): This is a pediatric-specific tragedy. A child lands on their head in a foam pit, and the initial CT scan in the ER looks “clean.” But because their spine is ligamentous and flexible, the cord has been torqued. Hours later, the ischemia sets in. If the park monitors weren’t trained to recognize the signs—as required by our Section M standards—the delay in treatment becomes part of our claim.
- Vertebral Artery Dissection: This is the Elle Yona TikTok mechanism. A rotation shears the artery in the neck, causing a stroke. It is frequently misdiagnosed as an anxiety attack in Ponder ERs. We know the imaging signature (MRA with T2-weighted sequences) that proves the injury.
Skeletal Growth & Salter-Harris Fractures
Every pediatric bone end has a growth plate. Our Section H internal dossier anchors in the reality that a Salter-Harris Type IV or V (crush) injury carries an extreme risk of growth arrest. We don’t settle catastrophic pediatric cases until we have an expert pediatric orthopedic forecast showing the child’s trajectory through skeletal maturity.
Compartment Syndrome & Rhabdo
If a fracture or crush injury causes extreme leg swelling, it can lead to acute compartment syndrome. If not caught within 6 hours by the park’s staff (who should have called 911), it causes permanent muscle death. This links directly to our $10M UH rhabdo litigation. We understand the myoglobin cascade and the renal risk better than any generalist firm in Texas.
Adjacent Attractions: The Dangerous “FEC” Pivot
In Ponder and throughout the I-35 corridor, parks are bolting on non-trampoline attractions. We handle injuries involving:
- Urban Air Go-Karts: Like the Emma Riddle fatality in 2025. We look for mechanical failures in the electric throttle systems.
- Sky Rider Ziplines: We know the chain-wide pattern of cord strangulations in Newnan, GA and Bloomingdale, IL. One Urban Air location in Vegas saw a 10-year-old fall 20 feet from a zipline during a birthday party.
- Climbing Wall Harnesses: Following the Matthew Lu / Altitude Gastonia NC death, we look for “auto-belay” failures and unpadded concrete subfloors.
- Ninja Warrior Courses: As seen in the Mathew Knight $3.5M Georgia verdict, unpadded frames on ninja courses cause open, comminuted fractures that end careers.
Evidence Strategy: What Ponder Families Need to Know
Most parents think the park will be “fair.” The reality is the Policy Limit Shell Game. The adjuster will tell you the policy is “only $1 million.” We use Section I of our database to find:
- The Operator Umbrella: (typically $2M-$10M).
- The Franchisor Excess: (typically $10M-$50M).
- The PE Sponsor D&O Insurance.
We also look for Arsenal Angle #14: Insurance Application Misrepresentation. If the park told their insurer they had a 1:32 monitor ratio but actually ran at 1:60, the insurer might try to deny coverage. We use that “bad faith” leverage to drive the settlement value higher.
Call 1-888-ATTY-911. We know every Ponder park, every Denton County court, and every corporate parent tactic. One call saves the evidence. One call starts the recovery. Hablamos Español. No fee unless we win.
Frequent Parent Objections & The Attorney911 Answer
“I can’t afford a lawyer right now with these hospital bills.”
You pay us nothing upfront. We advance every cost—the biomechanists, the surgeons, the digital forensic examiners who pull the DVR metadata. We only get paid if we win. Your child’s recovery fund stays untouched.
“The park manager was so nice and offered to pay our insurance deductible.”
That’s the Med-Pay Trojan Horse. That $3,000 check they want you to sign for often comes with a release that kills your multi-million dollar catastrophic claim. Don’t sign anything. Call us first.
“We already talked to their insurance adjuster.”
That’s okay. But stop talking now. They are recording every “I think” and “maybe” to use against you in a deposition later. Tell them: “I have hired the Manginello Law Firm. Talk to them.”
“What if I’m not a U.S. citizen?”
Your immigration status doesn’t matter for your child’s right to recovery in a Texas court. We represent families with mixed status throughout the North Texas metro. Ralph and Lupe provide a safe, confidential environment to discuss your family’s rights.
“It’s been three weeks. Is it too late?”
The statute of limitations is 2 years, but the Evidence Window is much smaller. If you haven’t sent a spoliation letter, that video from the day of the injury is being deleted soon. Call 1-888-ATTY-911 today so we can freeze the evidence.
Strategic Discovery: The “Insider Witness” Network
One thing that makes our firm different is how we find witnesses. Because most Ponder-area trampoline parks have a staff turnover of 130-150%, the monitors who saw your child get hurt probably don’t work there anymore.
They are no longer under the “HR thumb” of the park. We use Section G of our protocol to find them through LinkedIn alumni searches, state L&I complaint records, and local ex-employee networks. They are often willing to tell us the truth about understaffing that they were scared to tell their managers.
25 Years of trial. 50 states of knowledge. 1 call away.
From the I-35 corridor to the backyard streets of Ponder, our firm is the authority on trampoline park accountability. We don’t just file cases; we build architectures of proof. We cite Teague 2024, AJR 2024, and the EN ISO 23659 international standard. We pierce the private equity shields of Palladium and Seidler. We win.
Call 1-888-ATTY-911 now. The spoliation clock is running. Hablamos Español. Ralph Manginello and his team are ready to fight for your child.
Technical Standards Appendix: Proving the Breach in Ponder, TX
When your case goes to trial in Denton County, the jury needs a “rule book” to judge the park by. We provide that rule book:
- ASTM F2970-22: The American industry-written standard. We cite their own attendant-ratio and age-separation provisions back to them.
- EN ISO 23659:2022: The international standard published in November 2022. It is mandatory in Europe. We use it to show that what Sky Zone and Urban Air do in Ponder would be illegal in France or the UK.
- AAP 1999/2012/2019: The quarter-century of medical warnings that prove foreseeability.
- CPSC NEISS Data: Which proves the industry hides injuries.
We don’t hope they were negligent. We prove they chose to be.

Frequently Asked Questions
Can I sue if I signed the waiver for an Urban Air in Ponder, TX?
Yes. Despite the May 2025 Texas Supreme Court ruling in Cerna v. Pearland Urban Air, which sends some scope disputes to arbitration, your rights haven’t disappeared. In Texas, waivers do NOT cover gross negligence, and under the Munoz rule, parental pre-injury waivers are generally ineffective against a minor child’s direct personal injury claim. We specialize in naming the franchisor (UATP Management LLC) and the corporate parent (Unleashed Brands) to pierce the local operator’s limited policy. If they were understaffed or had torn equipment, the waiver won’t save them.
What should I do if my child has dark urine after visiting a Ponder-area trampoline park?
Seek medical help immediately. This is a primary symptom of Rhabdomyolysis, a medical emergency common in extended-jumping sessions in North Texas heat. Ask the ER for a Creatine Kinase (CK) test and a urinalysis for myoglobin. Because we are already litigating a $10M university rhabdo case, we have the medical experts ready to prove why the park’s lack of hydration and mandatory-break protocols makes them liable for your child’s kidney failure.
Do trampoline parks near Ponder, Texas, follow different rules?
Most parks claim to follow ASTM F2970, a voluntary industry standard. However, Texas has no state-specific trampoline safety law, which means many facilities operate in a “regulatory vacuum.” We use the international EN ISO 23659:2022 standard as a comparison to show how far below global safety norms North Texas parks actually fall. If they didn’t have a 1:32 monitor ratio on a busy Saturday, they were negligent.
Is my neighbor in Ponder liable for my child’s backyard trampoline accident?
Often, yes. Under the Attractive Nuisance doctrine, Ponder homeowners must secure hazardous equipment that attracts children. We investigate if the ladder was left in place or if the safety netting was UV-degraded by the harsh Texas sun—a common failure in Jumpking or Skywalker trampolines. We coordinate with homeowners’ insurance carriers, ensuring any “trampoline exclusion” is properly challenged by looking for excess umbrella layers.
How much can my family recover for a Salter-Harris growth plate fracture?
Because growth plate damage at age 8 can cause crooked or stunted growth at age 14, these cases are worth far more than your current ER bill. We build Life Care Plans that project medical monitoring and corrective surgeries through skeletal maturity. National settlements for serious pediatric fractures often reach the $500K-$2M range. We fight to make sure no future cost is left on the table.
Does Attorney911 offer Spanish services for families in Ponder?
Sí. Nuestro abogado Lupe Peña habla español nativamente y le representa directamente sin intérpretes. Entendemos la doctrina Delfingen en Texas, que puede invalidar un waiver si fue firmado en inglés por alguien que no domina el idioma bajo presión en el mostrador del parque. Llámenos al 1-888-ATTY-911.
What happens if the trampoline park video is “missing”?
We treat missing video as Spoliation. The Mathew Knight $3.5M Georgia verdict was won specifically because the park’s surveillance “glitched” on 4 cameras at the moment of injury. We send a preserved-evidence demand within 24 hours of being hired. If the video is gone, we ask the court for an adverse-inference instruction—meaning the jury must assume the video would have hurt the park.
How long does a trampoline injury lawsuit take in Ponder?
Serious cases typically resolve in 18-36 months. We file suit early to trigger formal discovery because the corporate parents—Sky Zone, Inc. (Palladium Equity) and Unleashed Brands (Seidler Equity)—don’t bring their best settlement offers until they know we have their internal risk-management emails and training logs. We prepare every case for trial from day one.
Can I sue the manufacturer of a backyard trampoline?
Yes. If your Ponder backyard trampoline had a frame weld failure or a net strap failure, we bring a Product Liability claim. Manufacturers like Jumpking and Skywalker have documented CPSC recall histories. We also apply the retailer-as-seller doctrine to Amazon or Walmart (Bouncepro) to ensure you have a deep-pocket defendant.
What should I do first?
Call 1-888-ATTY-911. Every minute the park waits for a 911 call is a minute the surveillance video is closer to overwriting. We take 24/7 calls and our spoliation letter goes out immediately. No fee unless we win.
Detailed Mechanism Spotlight: The Foam Pit Spinal Compression
In Ponder, families often assume foam pits are like “clouds.” They aren’t. They are open-cell polyurethane pits that compact over time.
- The Mechanism: If the pit isn’t fluffed daily—a violation of ASTM F2970—the cubes stay squashed. When your child lands head-first, their head stops but their body keeps moving. The result is C1-C4 cervical hyperflexion.
- The Industry Shift: The fact that Sky Zone and Urban Air are replacing pits with airbags is proof. The industry knows foam pits cause paralysis. If your park still has one in 2026, they are using outdated, dangerous equipment to save money.
- The Diagnosis: We look for SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). Many Ponder ERs miss this because it doesn’t show on a CT scan. You need an MRI. We find the neuroradiologists who understand why.
Detailed Liability Theory: The Franchise “Apparent Agency” Edge
The chain in Southlake or Lewisville will say: “We’re just a separate LLC, don’t sue corporate.”
We don’t accept that. Because they use the chain’s uniforms, the chain’s website to book your Ponder birthday party, and the chain’s national waiver, they represent themselves as one entity. This is Apparent Agency, and it lets us reach the deep-pocket insurance layers of the franchisor.
As client Chad Harris said: “You are NOT just some client… You are FAMILY to them.” We treat your child’s future like it’s our own family’s. We don’t settle for the local LLC’s $1M primary policy when your child’s ventilator care costs $5M. We go the distance.

Common Trampoline Accident Stems (Long-Tail Search Capture)
What to do if my child was injured at an Urban Air in Ponder?
If your child was injured at an adventure park, the first step is to stay with them and insist on a 911 call. Do not let the park “walk it off” or move your child. Once they are stabilized at a trauma center, call 1-888-ATTY-911. We need to capture the kiosk waiver transaction ID and the names of the attendants immediately. Because Unleashed Brands (Seidler Equity Partners) controls the operational manuals for every Urban Air, we subpoena the chain-wide pattern of similar incidents to prove their training was systemically inadequate.
Is the Sky Zone in Ponder responsible for a double-bounce?
Yes. The Nysted & Drogset 14x rule proves that a smaller child is fourteen times more likely to get hurt when a larger jumper is on the same bed. Sky Zone, Inc. (formed Feb 2023 from CircusTrix) has its own internal manual that commands “one jumper per bed.” If the monitor on duty was on their phone or watching another court, those 4 camera angles that “glitch” shouldn’t stop your lawsuit. We reach the primary, umbrella, and corporate excess layers that national chains carry.
How do I sue after a Ponder backyard trampoline net failed?
Backyard netting is made of polypropylene, which is destroyed by North Texas UV radiation within 2-4 years. If your child fell through a net on a Jumpking, Skywalker, or Bouncepro (Walmart private label) trampoline, you have a product liability claim. We look for a Failure to Warn—did the manual tell you to replace the net every two years? If not, the manufacturer is on the hook. Under the attractive nuisance doctrine, the property owner’s personal umbrella policy often responds to these claims as well.
What are the symptoms of rhabdo after jumping in Ponder?
Ponder parents need to watch out for the “cola-colored” urine and extreme muscle hardness that signals Exertional Rhabdomyolysis. This is a medical emergency that can lead to permanent dialysis. Because we currently litigate a $10M UH rhabdo case, we know that if the park was 85 degrees inside and didn’t enforce water breaks, they are liable for the institutional failure to monitor.
Why is my trampoline park insurer calling me so fast?
They want to use the Friendly Adjuster Trap. They know your child’s Salter-Harris growth plate fracture or SCIWORA diagnosis could be worth millions over their lifetime. They offer $5,000 for “medical payments” (Med-Pay) to get you to sign a release before you know the full extent of the damage. Don’t take the call. Our associate Lupe Peña used to train these adjusters; he knows how to silence them so your case can be valued fairly.
Can I sue the Ponder ISD for a trampoline injury?
Suing a school district involves the Texas Tort Claims Act, which has strict notice requirements (often as short as 60-180 days) and damages caps. However, the American Academy of Pediatrics has warned against trampolines in PE classes since 1999. If the school used a trampoline against this medical consensus, we look for ways to pierce sovereign immunity by showing the “operation of a motor-driven vehicle or equipment” or other statutory carve-ins.
How much does a trampoline park Go-Kart settlement pay?
Following the Emma Riddle fatality at Urban Air St. Lucie in 2025, go-kart mechanical failures are a serious focus. If a kart surged forward or had faulty brakes, we sue the manufacturer and the assembler. These cases often anchor in the multi-million dollar range due to the catastrophic mode of failure. We look at TDI Class B inflatable inspection records in Texas to see if the kart track was properly certified.
What if I didn’t sign the waiver at the Ponder location?
We love this question. Many people are at birthday parties or group events where a host parent signs for everyone. This is a massive break in the park’s defense. A parent cannot waive your child’s rights, but a “party host” definitely cannot. Under Texas Family Code § 153.073, only a parent or court-appointed conservator has signing authority. We break the waiver on day one.
1-888-ATTY-911. We represent families. We represent children. We represents Ponder parents. No fee unless we win.
