“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.”
Those words, spoken to ABC News by a mother named Kati Hill after her three-year-old son Colton suffered a broken femur at a trampoline park, resonate with every family in Wylie that has lived through a similar nightmare. One moment, your child is at a birthday party at a park near State Highway 78 or over in McKinney; the next, you are in a quiet ambulance heading toward Children’s Medical Center, wondering how a “supervised” facility could allow your child’s life to change in a single bounce.
We are Attorney911, led by Managing Partner Ralph Manginello. For over 25 years, our firm has stood at the bedside of families whose lives were upended by catastrophic negligence. We have gone toe-to-toe with Fortune 500 corporations like BP and Walmart, and we bring that same relentless weight to the trampoline industry. If your child was injured at a commercial park or on a defective backyard trampoline in Wylie, you don’t need a lawyer who “handles accidents.” You need a team that has memorized ASTM F2970, that knows exactly which clauses in an Urban Air or Sky Zone waiver are void under Texas law, and that includes a former insurance defense attorney, Lupe Peña, who used to write the very arguments these parks now use to deny your claim.
The trampoline park industry in North Texas has exploded, but the safety standards have not kept pace. In the 72 hours since your child was hurt, the park’s risk management team has already begun its work. Their surveillance video is on a 7-to-30-day overwrite cycle. Their incident reports are being “finalized” to frame the event as a “freak accident” or “guest error.” We operate faster. Our spoliation letters go out within 24 hours of retention. We know this wasn’t an accident; it was the predictable output of a business decision that put margin ahead of your child’s safety.
Call us at 1-888-ATTY-911. Hablamos Español. Your child’s recovery fund starts with a firm that doesn’t take “no” from a kiosk waiver for an answer.
The Reality of Trampoline Injuries in Wylie and Collin County
Wylie is a family-first community. Between the competitive youth sports cultures at Wylie High and Wylie East and the growing number of family entertainment centers in the surrounding DFW metroplex, our children are more “airborne” than any previous generation. But the physics of a trampoline don’t care about a child’s enthusiasm.
Nationally, the Consumer Product Safety Commission (CPSC) tracks over 300,000 trampoline-related emergency room visits every year. A staggering proportion of these occur at commercial parks. According to the groundbreaking Jan 2024 study in Pediatrics by Teague et al., the injury rate in foam pits is 1.91 per 1,000 jumper-hours. In a high-traffic park near Wylie on a Saturday, that means an injury is almost a statistical certainty.
More concerning for Wylie parents is the 1,100% increase in park-related emergency visits over the last decade documented by the American Academy of Pediatrics (AAP). While the parks market themselves as “safe family fun,” the medical reality is often comminuted fractures, traumatic brain injuries, and permanent spinal cord damage. Approximately 1.6% of all pediatric emergency department trauma visits are now trampoline-related (AJR/R3J 2024).
In Wylie, we see two distinct risk profiles:
- Commercial Parks: Facilities like Urban Air, Sky Zone, and Altitude which concentrate hundreds of jumpers in interconnected courts.
- Backyard Trampolines: Found in many of Wylie’s suburban neighborhoods, often becoming an “attractive nuisance” for neighborhood children and subject to the harsh North Texas sun, which degrades safety netting in as little as 24 months.
Whether the injury happened because a 200-pound adult double-bounced your 50-pound child or because a Jumpking or Skywalker net failed in a backyard, the responsibility lies with the party that failed to follow the standard of care.
Why 25 Years of Experience Matters for Your Wylie Case
When you hire Ralph Manginello and the team at Attorney911, you are hiring a firm that has litigated at the highest levels of the American legal system. Ralph Manginello, admitted to the Southern District of Texas and practicing since 1998, has secured multi-million dollar settlements for victims of traumatic brain injuries and spinal cord damage—the exact categories of injury caused by a catastrophic trampoline landing.
Our firm doesn’t just “sue parks.” We perform corporate archeology. We know that “Sky Zone” or “Urban Air” isn’t just one company. It’s a five-layer stack of Operator LLCs, Franchisees, Franchisors (like UATP Management LLC), and Private Equity sponsors (like Palladium Equity or Seidler Equity Partners). We have the experience from the BP Texas City refinery litigation to pierce through these corporate layers and find the deep pockets that actually cover a lifetime of medical care.
Furthermore, we are the only Texas firm currently litigating a $10 million lawsuit against the University of Houston and Pi Kappa Phi involving rhabdomyolysis and acute kidney failure. This is critical because “rhabdo” is a silent killer in trampoline parks. A child jumping for 90 minutes in a hot, under-ventilated facility in the Texas summer can arrive at a Wylie-area ER two days later with kidneys shutting down. We already have the medical experts, the nephrology protocols, and the accountability theories to win these cases.
As client Chad Harris said, “You are NOT just some client… You are FAMILY to them.” We treat every Wylie family with that level of care, while treating the insurance companies with a relentless’ attorney-led attack.
The Standard of Care: ASTM F2970, EN ISO 23659, and the Industry “Floor”
The most common defense a trampoline park will use is: “We met the industry standard.” We know that standard better than their managers do.
ASTM F2970 is the manual the trampoline industry wrote for itself to establish a safety floor. It dictates everything from attendant-to-jumper ratios (ideally 1:32) to foam pit depths and age-separation rules. But in 39 states, including Texas, this standard is largely voluntary at the state level. While New York and Utah have passed strict laws requiring CPR-certified staff and AEDs, Texas has no such statewide mandate for the trampoline decks themselves.
We expose this gap by comparing U.S. parks to the international benchmark: EN ISO 23659:2022. This is the mandatory European standard that treats trampoline safety as a ceiling, not a floor. When a park in North Texas tells you they were “safe enough,” we point to the international standard they chose to ignore to save on labor and maintenance costs.
If your child was hurt at a park that ignored the ASTM F2970 “one jumper per square” rule or failed to maintain a foam pit to the required depth, they have breached the duty of care. Our firm can cite these provisions from memory during a deposition, and we use that mastery to show that your child’s injury was 100% foreseeable and preventable.
Deconstructing the “I Signed a Waiver” Myth in Texas
If there is one thing we could tell every parent in Wylie, it is this: The waiver you signed at the kiosk is not a wall. It is a speed bump.
Many families hesitate to call us because they remember clicking “agree” on an iPad. But Texas law, specifically through the landmark cases of Munoz v. II Jaz and Dresser Industries v. Page Petroleum, provides powerful protections for families.
- Minors Cannot Be Bound: In Texas, a parent generally cannot sign away a minor child’s independent right to sue for personal injuries. Even if you signed the form, your child’s claim survives.
- Gross Negligence: No waiver in America can legally release a company from “gross negligence.” In Harris County, Texas, a jury awarded $11.485 million against Cosmic Jump after a teen fell through a torn slide onto concrete. The jury found that the park’s knowledge of the rip and failure to fix it constituted gross negligence, making the waiver irrelevant.
- Fair Notice: Under the Dresser doctrine, a release must be “conspicuous” and use the exact word “negligence” to be valid. Most kiosk waivers buried in 20 screens of text fail this test.
- Signer Authority: If a grandparent, aunt, or family friend signed for your child at a birthday party, Texas Family Code § 153.073 says they likely had no authority to do so, rendering the document void.
- Bilingual Formation: Under Delfingen US-Texas v. Valenzuela, if the waiver was only in English and your primary language is Spanish, the contract may be thrown out for lack of a valid “meeting of the minds.”
Our associate Lupe Peña knows which waiver holes to aim for because he used to defend these parks. He knows their playbook, and he knows how to shred it.
The Mechanisms of Injury: Why Every Second Matters
Trampoline injuries are driven by violent physics. In a Double-Bounce, a 200-pound adult lands on the mat just as a 60-pound child is taking off. The resulting energy transfer can multiply the child’s launch force by 4x, throwing them at a velocity their bones were never designed to absorb.
In a Foam Pit, a head-first landing can result in SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). This is a terrifying pediatric condition where the spinal cord is stretched or compressed, but the bones look “normal” on a standard CT scan. Six hours later, a child can become paralyzed because the park’s staff didn’t know to stabilize the neck.
The Elle Yona case, which went viral with over 27 million views on TikTok, highlights the risk of Vertebral Artery Dissection. A backflip into a foam pit caused a stroke in her spinal cord, initially misdiagnosed as a panic attack. At Attorney911, we know the radiology. We know AJR 2024’s findings on pediatric trampoline trauma from head to toe. We don’t guess at the medicine—we prove it.
The Evidence Clock: DVR Overwrites and Scene Spoliation
If your child was injured at a Sky Zone, Urban Air, or DEFY near Wylie, the clock is your enemy.
Most park DVR systems are set to overwrite footage in as little as 7 to 10 days. The original incident report is currently being “revised” on a corporate server. The foam pit blocks that caused the injury may be rotated or replaced by Monday morning.
This is why we send Spoliation Letters within 24 hours. We don’t just ask for the video; we demand the hard drive, the access logs, and the metadata. We look for “Glitch Spoliation”—a tactic where video “malfunctions” exactly at the moment of injury. In a Georgia case (Mathew Knight), a jury awarded $3.5 million because the defense video glitched on four cameras simultaneously. We don’t believe in coincidences; we believe in forensic digital evidence.
Catastrophic Pediatric Injuries: Growth Plates and Lifelong Care
A “broken leg” at age seven is a lifelong medical event. Most generalist firms don’t understand the Salter-Harris classification. If a fracture crosses the growth plate (the physis), the bone may never grow straight again. Your child may need corrective osteotomies at age 12, 14, and 18.
We build a Pediatric Life-Care Plan for every child we represent. This means forecasting medical costs into the year 2080 and beyond. We account for:
- Future surgeries and hardware removal.
- Special education needs following a TBI.
- Lifetime attendant care for spinal injuries.
- Occupational and speech therapy.
- The “concussion baseline gap”—proving the cognitive loss when the park failed to screen.
When we tell an insurance company your case is worth millions, we aren’t pulling a number out of the air. We are using the same life-care planning and forensic economic models that Ralph Manginello has used for 25 years in federal court.
The Corporate Scale: Fighting Multinational Parents
Sky Zone, Inc. reported systemwide sales of $642 million in 2024. They are backed by Palladium Equity Partners. Urban Air is part of Unleashed Brands, recently acquired by Seidler Equity Partners “amid lawsuits,” as the Franchise Times famously put it.
These companies are built to maximize margin. That marginal profit often comes from cutting the court monitor’s pay to minimum wage or hiring teenagers with only two hours of training. When they break federal child labor laws—as seen in the $68,000 fine for Sky Zone Tukwila or the citations at Sky Zone Vancouver—it’s a window into their culture. If they’ll break the law for their own teenage employees, why would they follow the safety rules for your child?
We have the resources to fight these conglomerates. We advance all costs—the biomechanical engineers, the pediatric orthopedists, the ASTM experts. You pay nothing unless we win.
Frequently Asked Questions (Wylie Parents’ Guide)
Can I sue if I signed the waiver at an Urban Air or Sky Zone near Wylie?
Yes. As we’ve detailed, Texas courts regularly void or ignore waivers for minors’ claims. Furthermore, waivers never cover gross negligence or reckless disregard of safety standards. If the park failed to separate jumpers by weight or speed, they violated their own standard, and the waiver likely won’t protect them.
What should I do if the park manager tells me not to call 911?
Call 911 yourself. There is a documented industry pattern (Urban Air Southlake for example) where managers are instructed to downplay injuries to avoid creating a public record. Your child’s health is the priority. The park’s refusal to call EMS is powerful evidence of conscious indifference in a future lawsuit.
How do I know if my child has rhabdomyolysis after jumping?
Watch for “cola-colored” or dark brown urine and muscle pain that seems extreme 12 to 48 hours later. This is a medical emergency that can lead to acute kidney failure. Because we are litigating a $10 million rhabdo case against a major university, we have the nephrology experts ready to document your child’s injury properly.
How much is my child’s trampoline injury case worth?
It depends on the medicine. A simple fracture might settle for $50,000 to $500,000. A Salter-Harris growth plate injury can cross the $1 million mark. A catastrophic spinal cord injury or TBI can result in settlements or verdicts ranging from $5 million to over $15 million, as seen in the Damion Collins ($15.6M) and Cosmic Jump ($11.485M) cases.
Is a backyard trampoline accident different from a park accident?
Yes. Backyard cases involve Homeowner Liability and Attractive Nuisance doctrine. Homeowner’s insurance often excludes trampolines, which means we must look at the manufacturer (Jumpking, Skywalker) for design or manufacturing defects. In Texas, we hold homeowners accountable when a child wanders onto their property and is injured by a hazardous condition like an un-netted trampoline.
Why not just let my health insurance handle it?
Your health insurance will pay for the initial ER visit, but they will file a “subrogation lien” to get their money back from any settlement. Your health insurance also won’t pay for your lost wages, your child’s future surgeries, the pain and suffering, or the loss of enjoyment of life. A lawsuit is the only way to make your family truly whole.
Do I have to pay anything upfront?
No. We work on a contingency fee basis. We pay for the private investigators, the forensic engineers, and the pediatric consultants. If we don’t win your case, you owe us nothing.
Why should I call Attorney911 instead of a local Wylie generalist?
A generalist lawyer sees a “slip and fall.” We see a breach of ASTM F2970 Section 10. We see a corporate structure engineered by private equity. We see an insurance tower with umbrella and excess layers that a generalist will never find. You need an attorney who has already beaten the biggest companies in the world.
What if my child was injured by another child?
The park is still liable. A trampoline park cannot outsource its duty to supervise to other children. If a larger child was allowed to jump near yours, the park failed its ratio and age-separation duties. We hold the facility accountable for the environment they created.
How long do we have to file?
While the Texas statute of limitations is two years (and tolled for minors), the “evidence statute” is days. If the video is deleted, the case becomes much harder. Call us before the DVR overwrites the truth.
Can I sue for an infection acquired in a foam pit?
Yes. Foam pits are sanitization disasters. Foam blocks absorb blood, sweat, and vomit and cannot be cleaned. If your child developed a MRSA or staph infection after visiting a park, that is a premises liability claim focused on unsanitary conditions.
Is the Wylie area served by a Level 1 trauma center?
Serious injuries in Wylie are often stabilized locally and then routed to Children’s Medical Center Dallas or Cook Children’s, both elite Level 1 pediatric trauma centers. The standard of care at these named facilities is the benchmark against which we measure your child’s treatment and the extent of their injuries.
The Architecture of Responsibility
What happened to your child wasn’t a “freak accident.” It was the output of a system designed to generate $642 million in sales for private equity firms while leaving families to deal with the medical consequences. The hardware failure, the lack of supervision, and the “don’t call 911” protocols are not bugs in the system—they are the system.
We were built for this. With 25 years of catastrophic injury experience, admission to federal court, and the insider knowledge of an attorney who used to defend these very parks, we bridge the gap between “we had no idea” and “they must pay.”
Your family deserves justice. Your child deserves a future that is fully funded.

Detailed Injury Analysis for Wylie Families
Traumatic Brain Injury (TBI) in Developing Brains
At Attorney911, we understand that a “concussion” at age eight is different than one at age thirty. The developing pediatric brain is subject to Diffuse Axonal Injury (DAI), where the shearing of fibers affects white-matter junctions. This may not show up on an initial CT at the ER, but it manifests six months later as academic regression, behavioral shifts, or executive function loss. We retain pediatric neuropsychologists to establish a baseline and prove the cognitive-earning cascade loss.
Spinal Cord Infarction and Vertebral Artery Dissection
The Elle Yona mechanism highlights a danger parks never disclose: the Spinal-Cord Stroke. When a child’s neck hyper-flexes during a backflip, the vertebral artery can suffer an intimal tear. This often presents as a “panic attack” because of the atypical symptoms in the young. We know how to read the MRA flow voids and cord T2 hyper-intensities that prove the park’s failure to supervise “Advanced Skills” zones caused the stroke.
Pediatric Femur Fractures
The femur is the hallmark trampoline fracture. It requires ORIF (Open Reduction Internal Fixation) with intramedullary nailing. For Wylie families, this means months in a wheelchair and years of bracing. A Salter-Harris Type V fracture—a crush injury to the physis—carries the worst prognosis for growth arrest. We make sure the life-care plan includes every corrective osteotomy your child will likely need over the next decade.
Exertional Rhabdomyolysis
If your child jumped for ninety minutes at an Urban Air or Sky Zone near Wylie during a 100-degree Texas heatwave and later experienced “cola-colored” urine, they are in a medical emergency. The breakdown of muscle tissue releases myoglobin, which is toxic to the renal tubules. Our active $10 million UH case gives us the technical superiority to litigate the CK (creatine kinase) trajectory and renal-failure causation in these ignored rhabdo cases.
Splenic Ruptures and OPSI Risk
A collision with a frame or another jumper can rupture a child’s spleen. If the spleen is removed (splenectomy), your child faces Overwhelming Post-Splenectomy Infection (OPSI) risk for life. This is a hidden damage that most firms miss. It requires a lifetime of vaccinations and a reduced life expectancy. We value these claims accurately because we know the long-term medicine.
The Liability Stack: Who We Hold Accountable
We name every person and entity responsible.
- Operator LLC: The local entity running the park.
- Franchisor: Sky Zone Franchising LLC or UATP Management LLC, who mandated the safety manual.
- Corporate Parent: Unleashed Brands or Sky Zone, Inc.
- Private Equity Sponsor: Palladium or Seidler Partners, whose cost-cutting led to the understaffing.
- Manufacturer: Ropes Courses Inc. (climbing walls) or Jumpking (backyard).
- Landlord: The shopping center owner who allowed a dangerous tenant to operate without proper code compliance.
We find the additional-insured layers that most generalist firms overlook. The primary $1M policy is just the starting point.
Why Wylie Chooses Attorney911
We are based in Houston, Austin, and Beaumont, but we work in every corner of Texas. We know the 51% comparison rule in CPRC § 33. We know the Munoz rule. We know the Dresser rule. And we know that Wylie families are looking for more than a settlement—they are looking for someone to stand up to the deep-pocketed conglomerates and win.
As client Donald Wilcox said, “One company said they would not accept my case. Then I got a call from Manginello… I got a call to come pick up this handsome check.” Don’t let a “no” from another firm stop you. Trampoline cases are technical, difficult, and waiver-heavy. We specifically take the cases other firms reject because we know how to win them.

Frequently Asked Questions — Trampoline Injuries in Wylie
What if my child was injured on a “Sky Rider” or a climbing wall instead of a trampoline?
This is becoming more common as Urban Air and Altitude expand into “adventure parks.” The Sky Rider Zipline has a documented chain-wide pattern of strangulation and fall failures (Newnan GA, Bloomingdale IL, FL, and IL). Climbing walls over concrete are a known design defect (Matthew Lu / Gastonia NC). We treat these as separate counts of negligence and product liability, often reaching the attraction manufacturer like Ropes Courses, Inc. directly.
Does it matter if my kid didn’t go to the ER right away?
It’s better if they did, but many trampoline injuries—like growth plate fractures, rhabdo, and internal organ damage—don’t show their full severity immediately. Don’t let a delay in treatment discourage you. We can use medical experts to bridge the gap between the incident and the diagnosis.
Can we sue for the emotional trauma and PTSD our child is suffering?
Yes. Pediatric PTSD from a catastrophic injury is a major damages category. Children often develop “social withdrawal,” nightmares, and “return-to-play fear.” We include pediatric psychologists and psychiatrists in our expert panel to quantify the lifelong impact of the trauma on your child’s development.
Is my immigration status a barrier to suing for my child?
Absolutely not. In Texas, a child’s right to recovery is independent of their family’s immigration status. Our firm is a safe place for families. Communication with your attorney is privileged. We never disclose your status to anyone, and it does not affect the calculation of your child’s damages.
What happens if the park’s surveillance video “glitched” at the exact moment of the injury?
We pursue a Spoliation Motion. If we can prove the park had notice to preserve the video (via our 24-hour letter) and it “happened” to fail, we ask the judge for an Adverse Inference Instruction. This tells the jury they are allowed to assume the video would have shown the park was negligent. We have done this successfully in multi-million dollar cases.
My child’s pediatrician said she’ll be “fine,” but she’s still in pain months later. What now?
Get a second opinion from a pediatric orthopedic specialist. Trampoline injuries are routinely under-diagnosed by general practitioners. We can help you navigate finding the right medical experts who specialize in children’s musculoskeletal systems to make sure her growth plates aren’t permanently damaged.
Can I sue if the waiver was presented on an iPad that I had to sign in ten seconds?
Yes. Texas “Fair Notice” and “Conspicuousness” principles (the Dresser doctrine) require that you have a meaningful opportunity to read and understand the release. A rushed electronic process at a busy front counter is a classic “Procedural Unconscionability” argument we use to throw out the waiver.
Who is the best expert for a trampoline case?
It’s a team effort. We usually retain a Biomechanical Engineer to reconstruct the impact, a Pediatric Orthopedist to explain the bone growth, and an ASTM Compliance Expert to show which safety rules the park broke. This three-part expert stack is why we win.
Is Wylie High School football off-season training allowed at these parks?
Many athletes use these parks for “conditioning.” But without professional trampoline coaching, it is incredibly dangerous. If a coach or school organized a trip to a park that didn’t meet ASTM standards, the school or organization may have its own layer of liability.
What should I say to the park’s “Incident Investigator” who calls?
Tell them you are represented by Attorney911 and to call 1-888-ATTY-911. Do not give a statement. They are not trying to help; they are trying to find a way to blame you or your child.
How do we get our child’s medical bills paid while the case moves?
We can often work with medical providers on a Letter of Protection (LOP). This allows your child to get the care she needs today with the understanding that the bills will be paid from the settlement or verdict at the end. You don’t have to choose between your savings and your child’s health.
What is the most important document in a trampoline park case?
The Initial Incident Report, before the park’s corporate lawyers had a chance to edit it. We subpoena the metadata in the park’s computer system to see the version history. The first draft often tells the truth that the final version tries to hide.
The Bottom Line for Wylie Families
What happened to your child wasn’t just “unfortunate.” It was a failure by an industry that profits from the risk while you pay the price.
Attorney911 brings the authority, the medicine, and the corporate-fighting experience of 25 years to every Wylie case. We know exactly what to do. We know exactly who to sue. And we know exactly how to defeat the kiosk waiver that the park is hiding behind.
Your child’s case is decided by what gets preserved this week.
