One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park.
If your child was injured at an indoor jump center near the City of Hilshire Village, you are living through a nightmare that has become tragically common in Harris County. You were likely at a birthday party or a weekend family outing, perhaps at a facility along the I-10 or Beltway 8 corridors. You signed the electronic waiver on the iPad because the line was long and the kids were excited. Twenty minutes later, you were in the back of an ambulance headed toward a Level 1 pediatric trauma center like Texas Children’s Hospital or Children’s Memorial Hermann.
You may have heard Kaitlin “Kati” Hill describe her own experience to ABC News after her three-year-old son Colton broke his femur at a park. Her words echo in the minds of every parent we represent: “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.” KatiHill’s warning was shared over 240,000 times on Facebook because it touched a nerve. Families in the City of Hilshire Village had no idea. We would have never put our children on these machines if we had known the truth.
At Attorney911, led by Ralph Manginello with over 25 years of courtroom experience, we know the truth that the multi-billion-dollar trampoline industry tries to hide behind kiosk waivers and minimum-wage attendants. Whether the injury happened at an Urban Air, a Sky Zone, an Altitude, or a backyard trampoline in one of the City of Hilshire Village’s wooded neighborhoods, we are built for this fight. We have gone toe-to-toe with Fortune 500 corporations like BP, Walmart, and Amazon. The parent conglomerates behind national trampoline park chains — Sky Zone, Inc. and Unleashed Brands — don’t intimidate us. We know their playbook because our team includes a former insurance defense attorney, Lupe Peña, who used to write and defend the very waivers they are using against you now.
What happened to your child in the City of Hilshire Village wasn’t an accident. It was the predictable output of a business model that prioritizes throughput and profit margins over the safety standards of the American Academy of Pediatrics (AAP). Since 1999, the AAP has warned that trampolines should not be used for recreational purposes at home or in schools. The industry ignored that warning, scaled the risk to massive indoor facilities, and then wrote its own safety floor, ASTM F2970, which they routinely violate.
If you are standing at a hospital bedside in Harris County right now, you need more than a lawyer; you need a system of accountability. Call us at 1-888-ATTY-911. We answer 24/7. Hablamos Español. Our spoliation letters go out within 24 hours of retention because we know that in the City of Hilshire Village area, park surveillance video is often overwritten in as little as 7 to 30 days. The case starts the moment you call.
The Harris County Benchmark: Why the Waiver is Not a Wall
The first thing a park manager or an insurance adjuster will say to a family in the City of Hilshire Village is, “You signed a waiver.” They want you to believe the case is over before it begins. In Harris County, we know better.
Our firm anchors its trampoline practice in the strongest local precedent available: the Cosmic Jump verdict. In Harris County, a jury awarded $11.485 million — including $6 million in punitive damages — against the operator of Cosmic Jump after a 16-year-old fell through a torn trampoline slide onto a concrete floor and suffered a traumatic brain injury. The waiver was signed. The jury found gross negligence anyway. That remains the largest reported jury verdict against a U.S. commercial trampoline park, and it happened right here in our backyard.
When we represent a family from the City of Hilshire Village, we apply a five-vector attack to dismantle that waiver:
- Gross Negligence Carve-Out: Texas law and the Texas Supreme Court in the Moriel decision make it clear: you cannot waive liability for gross negligence. If the park knew of a torn mat, an understaffed court, or a shallow foam pit and consciously indifferent to that risk, the waiver fails.
- Inadequate Conspicuousness: Under the Dresser fair-notice doctrine, a release must be “conspicuous.” If the legal language was buried in a 20-screen iPad click-through at a park near the City of Hilshire Village, it may be legally void for lack of fair notice.
- Parental Indemnity for Minors: In the landmark Munoz v. II Jaz Inc. case, a Houston appellate court ruled that a parent cannot bind a minor child to a pre-injury waiver of their personal injury claim. Your signature might affect your own rights, but it usually cannot extinguish the rights of your child in the City of Hilshire Village.
- Bilingual Formation Issues: We invoke the Delfingen doctrine. If your family’s primary language is Spanish and you were pressured to sign an English-only waiver at a park in West Houston or Harris County without an explanation or a translation, there was no “meeting of the minds.” Lupe Peña speaks directly to our Spanish-speaking clients to ensure their rights are protected.
- Scope of Risk: A waiver covers “inherent risks.” It is inherent to land awkwardly on a well-maintained mat. It is not inherent to be double-bounced by an adult four times your size because an attendant was on his phone.
The waiver is noise. It is a tool designed to make families in the City of Hilshire Village give up. We don’t give up. We pierce the corporate layers to find the money upstream.
The Five-Layer Defendant Stack: Who Really Pays?
“Sky Zone” or “Urban Air” are not just names on a building; they are complex, layered corporate structures designed to shield assets from families in the City of Hilshire Village. When we file a lawsuit in Harris County, we perform a corporate archeology to identify every possible pocket of recovery:
- The Operator LLC: This is the single-location business in the City of Hilshire Village area. They usually have a $1 million primary policy — which is often exhausted by the first week of ICU care for a spinal cord injury.
- The Franchisee: Many Houston-area parks are owned by multi-unit groups that own five, ten, or twenty locations. They have their own umbrella and excess layers.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC (Urban Air’s franchisor). Recent arbitration awards, like the $15.6 million award for Damion Collins in Kansas, prove that the franchisor can be held liable for “systemic failure” to implement safety changes. In that case, the franchisor absorbed 40% of the fault.
- The Corporate Parent: Sky Zone, Inc. (formerly CircusTrix) is backed by the private equity giant Palladium Equity Partners. Urban Air’s parent, Unleashed Brands, is backed by Seidler Equity Partners. These firms approve the budgets that often result in cutting the very attendant ratios required by ASTM F2970.
- The Manufacturers: If a spring snapped, a zipper failed, or a harness on a climbing wall came loose, we name the manufacturer. For example, Ropes Courses, Inc. was the manufacturer involved in the Matthew Lu fatality at an Altitude park.
We litigated the BP Texas City refinery explosion because we aren’t afraid of Fortune 500 defense firms. We leverage our federal court experience in the Southern District of Texas to ensure that when a child from the City of Hilshire Village is hurt, the multi-million-dollar insurance towers of these conglomerates are on the table.
Tragedy in the Foam Pit: The Physics of a Catastrophe
Foam pits are marketed as the “softest” place in the park. In reality, they are one of the most dangerous. The medical literature and biomechanical engineering studies, including the work of David Eager (2012), show why. A foam pit is an “unstable landing surface.”
When a teenager from the City of Hilshire Village attempts a backflip into a foam pit, their head can wedge between the foam cubes. Because the cubes apply uneven friction, the head stops while the rest of the body’s momentum continues. This creates a “cervical hyperflexion” or “axial loading” event — a fancy way of saying it snaps the neck. This was the mechanism that killed Ty Thomasson in 2012 and what led to the passage of “Ty’s Law” in Arizona.
In June 2024, a teen named Elle Yona went viral on TikTok (over 27 million views) documenting her journey with a spinal-cord stroke sustained in a Miami foam pit. She was initially misdiagnosed with a “panic attack” — a common error we see in Harris County ERs when treating vertebral artery dissections.
The industry knows foam pits are dangerous. That is why major chains are desperately trying to replace them with airbags. But for many parks near the City of Hilshire Village, if they haven’t made the swap, it’s a margin decision. They are breaking ASTM F2970, which requires specific depths and foam density. If that pit is compacted, your child might as well be landing on the concrete floor.

The “Double-Bounce” and the 4x Power Multiplier
If you have ever seen an adult and a small child jumping on the same mat in the Houston area, you have witnessed a double-bounce waiting to happen. Kinetic energy transfer is pure physics. When a 200-pound adult lands on the trampoline bed at the same instant a 50-pound child is pushing off, the energy from the adult is transferred through the mat into the child.
The result isn’t a higher jump. It is a launch with force multiplied by up to four times. The child isn’t jumping anymore; they are being thrown. This is the primary cause of “trampoline fractures” — proximal tibial metaphyseal buckle fractures typically seen in children under six.
ASTM F2970 and Sky Zone’s own internal manuals require age and weight separation. When a park monitor near the City of Hilshire Village allows a father to double-bounce his toddler, the park has violated its own industry standard. We don’t ask if they were negligent. We ask how many times the franchisor’s audits found they were understaffed and did nothing about it.
Rhabdomyolysis and the University of Houston Connection
Attorney911 brings a unique medical edge to trampoline cases in the City of Hilshire Village. We are currently litigating a $10 million lawsuit against the University of Houston regarding rhabdomyolysis and acute kidney failure.
Rhabdo is a catastrophic muscle breakdown. It happens when a child jumps for 90 to 120 minutes straight in a hot, poorly ventilated indoor park near the City of Hilshire Village, often drinking only a sugary soda. The muscle cells rupture and release myoglobin into the blood, which clogs the kidneys.
If your child comes home from a park and has “cola-colored” or dark brown urine 24 hours later, this is a medical emergency. They are at risk of permanent kidney failure. Because we are already litigating rhabdo at the university level, we have the medical experts and the biochemical protocols ready to prove your case. We know how to document it, how to prove it, and how to make the park pay for the lifetime of nephrology care your child may need.
The Evidence Clock: Why the Next 7 Days Are Critical
While you are focusing on surgeries and casts, the trampoline park’s risk management team is already working. They have a system designed to ensure that evidence from the City of Hilshire Village vanishes.
- Surveillance Video: Most digital video recorders (DVRs) at Houston-area parks are set to overwrite every 7, 14, or 30 days. If we don’t send a formal spoliation demand, that footage—the only objective record of the attendant’s inattention—is gone forever.
- Incident Reports: We often see public reviews, like the one from Urban Air Southlake, alleging that staff are told to “down-play injuries” and avoid calling 911. The original incident report filled out at the scene might say “Equipment Failure,” but by the time it reaches the corporate office in Bedford or Provo, it has been “updated” to say “Guest Error.” Our digital forensics team pulls the metadata to prove when and how those reports were altered.
- Witness Decay: The 17-year-old “court monitor” who witnessed the injury will likely quit or be fired within three months. We use our ex-employee outreach network and LinkedIn alumni searches to find those witnesses while their memories are fresh.
If the park told you the video “wasn’t working” or “didn’t capture the angle,” that is a Matthew Knight-type problem. In a Georgia case, a jury awarded $3.5 million because the park’s surveillance “glitched” on four different cameras at the exact moment of the injury. We know how to turn their “technical failure” into an adverse-inference instruction that wins your case.

Growth Plates and the Decade of Monitoring
A “broken leg” for a child in the City of Hilshire Village is never just a broken leg. If the fracture line extends through the physis — the growth plate — your child has a Salter-Harris fracture.
Pediatric bone is biomechanically distinct. The growth plate is the weakest part of the skeleton. If it is crushed or displaced on a trampoline, the bone may stop growing, grow crooked, or grow at a different rate than the other leg. This damage might not be visible for two, three, or five years.
Our life-care planners and pediatric orthopedic experts don’t just calculate today’s ER bill. We calculate the cost of the corrective osteotomies, the physical therapy through skeletal maturity, the lost athletic scholarships, and the lifetime of biomechanical adjustments your child will face at age 14 or 18. We don’t settle for the $3,000 “Med-Pay” check the adjuster offers to close the file. We settle for the future of your child.
Backyard Trampolines and Attractive Nuisance
While we focus heavily on parks, we know that many families in the City of Hilshire Village have trampolines in their own yards — Jumpking, Skywalker, Springfree, or Bouncepro models from Walmart.
If a neighbor’s child wandered onto your property and was injured, Texas law applies the Attractive Nuisance doctrine. This means that if you have an artificial condition on your land that is attractive to children (like a trampoline) and you fail to secure it with a fence or a locked gate, you can be held liable even if the child was trespassing.
Furthermore, many homeowners’ insurance policies in the City of Hilshire Village explicitly exclude trampoline injuries. If your insurer denies the claim, you need a firm that can look at the product liability angle. Was the net UV-degraded? Did a frame weld snap like in the 2005 Jumpking recall of one million units? Even if the insurance says no, the manufacturer or the retailer (like Amazon or Walmart under the Bolger doctrine) may be on the hook.
Why Choose Attorney911?
You are not looking for a “generalist.” You are looking for a team that has memorized ASTM F2970 line by line.
- 25+ Years of Trust: Ralph Manginello has been fighting for families since 1998. He knows the Harris County courts and the federal dockets better than the corporate defense firms do.
- The Defense Advantage: Associate Attorney Lupe Peña used to sit on the other side of the table. He knows exactly which waiver clauses Texas courts will void and which “Independent Medical Examination” doctors the insurance companies keep on speed dial.
- We Advanced Everything: You pay nothing unless we win. We advance the costs of the biomechanical engineer who will model the energy transfer, the pediatric neurologist who will explain the TBI, and the ASTM compliance expert who will take the park manager apart in deposition.
- Family First: As client Chad Harris said, “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.” We represent the parent at the trauma-bay bedside. That’s who we are.
Frequently Asked Questions for City of Hilshire Village Families
Can I sue if I signed the waiver at the park?
Yes, in almost every case. As established in the Cosmic Jump verdict in Harris County, a waiver does not protect a park from gross negligence. Additionally, Texas courts frequently hold that parents cannot waive a minor’s right to sue for their own personal injuries. The waiver is the beginning of the legal argument, not the end.
How much is my child’s trampoline injury case worth?
Settlements and verdicts for trampoline injuries vary wildly based on the severity. Minor fracture cases with clear liability may range from $50,000 to $500,000. Catastrophic spinal cord or brain injury cases can result in nuclear verdicts or settlements over $10 million. At Attorney911, we have recovered multi-million dollar settlements for catastrophic categories including TBI and spinal injuries.
What should I do if the trampoline park manager tells me not to call 911?
Call 911 yourself immediately. Multiple parents have reported that parks instructed staff NOT to call emergency services to avoid creating a public record of the injury. This is a documented industry tactic designed to downplay the severity of the incident. Your child’s health comes first; the park’s reputation comes last.
How long do I have to file a lawsuit in Texas?
The general statute of limitations for personal injury in Texas is two years from the date of the accident. However, for a minor under the age of 18, the two-year clock typically doesn’t start until their 18th birthday. Warning: While the legal clock may be long, the evidence clock is incredibly short. Surveillance video, staff statements, and equipment conditions change or disappear within days. You must act fast to preserve your case.
Does it cost anything to hire your firm?
No. We work on a contingency fee basis. This means we take 33.33% of the settlement pre-trial or 40% if the case goes to trial. We advance all litigation expenses — every expert fee and court cost. You pay zero upfront. If we don’t recover money for you, you owe us nothing.
Why is rhabdomyolysis so dangerous after a trampoline park?
Exertional rhabdomyolysis can lead to acute kidney failure and death. Because it often presents 24 to 48 hours after the physical activity, many Harris County ER doctors miss the connection. Because our firm actively litigates a $10 million rhabdo case against the University of Houston, we have the specialized knowledge to link the park’s heat and exertion levels to your child’s kidney damage.
Can I sue the corporate headquarters (Urban Air, Sky Zone, etc.) or just the local park?
In most cases, we sue both. Under the theory of apparent agency, the franchisor (the headquarters) can be held liable for the safety failures of the local franchisee. This is critical because the local LLC often carries much lower insurance limits than the national corporate parent. We go upstream to reach the deeper pockets.
My child’s primary language is Spanish — was the waiver valid?
If the waiver was only provided in English and your family was not given a meaningful opportunity to understand it, the Delfingen doctrine in Texas allows us to challenge the validity of that agreement. Lupe Peña is a native Spanish speaker and can discuss these formation defects with you directly. Hablamos Español.
What if the park says my child caused their own injury?
The “guest error” defense is the standard fallback for every park insurer. However, children under the age of seven are legally presumed incapable of negligence in many contexts, and kids up to 14 are held to a much different standard than adults. Moreover, the park’s duty to supervise and enforce ASTM F2970 is non-delegable. They cannot blame a child for a risk they were paid to prevent.
What is the most important piece of evidence in a trampoline case?
The surveillance video. It is the only “unbiased” witness. We take immediate legal action to prevent the park from “losing” or overwriting that footage. Without that video, the park will almost always claim your child was “doing unauthorized flips.” With it, we can prove the attendant was distracted or the court was over-capacity.

Beyond the Park: Adjacent Attraction Hazards
Modern “trampoline parks” in the Harris County area have evolved into Family Entertainment Centers (FECs). They are bolting on go-kart tracks, Sky Rider ziplines, and climbing walls. These attractions are often even more dangerous than the trampolines themselves.
- Sky Rider Strangulation: There is a documented chain-wide pattern of Sky Rider ziplines causing cord strangulation, including a 2023 case in Newnan, Georgia, where a six-year-old was rescued by her father because staff did not intervene.
- Harness Failure: In June 2022, a 14-year-old fell 30 feet from a Sugar Land Urban Air climbing wall because the harness was not attached.
- Go-Kart Mechanical Failure: On December 6, 2025, six-year-old Emma Riddle died in Port St. Lucie, Florida, after an electric go-kart at an Urban Air surged forward due to a mechanical failure.
Whenever these attractions are involved, we look at whether the waiver was even drafted for them. Most “trampoline waivers” were written for mats and springs, not motor vehicles or ropes courses. This “scope gap” is a major litigation weapon for families from the City of Hilshire Village.
The Case-Build: How We Win for City of Hilshire Village Families
When we take your case, we don’t just “handle” it. We build it using a 10-step catastrophic-injury protocol:
- Immediate Spoliation: Certified letters to the park and franchisor within 24 hours.
- Forensic Capture: We use Wayback Machine and digital tools to preserve the park’s website and waiver version history before they can “update” it.
- Expert Panels: We retain a biomechanical engineer, a pediatric orthopedic consultant, and an ASTM safety specialist in the first week.
- Medical Chronology: A specialist reviews every ER and surgical record from the Harris County trauma bay to build the damage’s foundation.
- Corporate Piercing: We pull the Franchise Disclosure Document (FDD) Item 3 to find every other time that chain has been sued for the same thing.
- Staff Archaeology: We use LinkedIn to find former attendants who are no longer under the park’s control and are willing to tell the truth about understaffing.
- NEISS Custom Query: We pull the federal CPSC data specifically for the park’s equipment to prove they had notice of the defect.
- Digital Forensics: If the park “lost” the video, we subpoena the DVR hard drive for forensic extraction.
- Life-Care Planning: We forecast the next 70 years of your child’s medical and educational needs.
- Trial Readiness: We prepare every case as if it is going to a jury in downtown Houston. That readiness is why insurers offer top-dollar settlements.
Closing Statement: The Case is Decided Now
What happened to your child at City of Hilshire Village wasn’t an accident — it was the predictable output of a system. The AAP has been warning against trampolines since 1999. ASTM F2970 was written by the trampoline industry itself to establish a safety floor, and the park you visited operated below that floor to hit a profit target. The waiver was drafted by corporate counsel who knew it wouldn’t hold in a Texas court under the Munoz and Dresser standards. The surveillance is engineered to overwrite before you even have a chance to secure a surgeon’s opinion.
Attorney911 was built for exactly this fight. Ralph Manginello brings 25+ years of experience and federal court expertise into the room. Lupe Peña knows the defense script because he used to write it. We currently litigate a $10 million lawsuit against a major university for rhabdomyolysis — the same medical crisis your child may be facing. We know the experts, we know the Harris County juries, and we know how to win.
Your child’s case is decided by what gets preserved this week. By Day 10, the video is gone. By Day 30, the “updated” incident report is the only one left. By Day 60, the attendant is at a different job. The clock is running.
Call 1-888-ATTY-911. Hablamos Español. No fee unless we win. Our spoliation letter goes out within 24 hours of your call. The recovery for your family starts today.
