One second, your child was in the air at a trampoline park near City of La Marque—laughing, jumping, and celebrating a birthday. The next second, the air was filled with what Texas mother Kaitlin Hill described to ABC News as “the worst scream that you could ever have heard from a child.”
At Attorney911, we know that scream. We know the silence that follows in the back of the ambulance as it speeds toward a Level 1 pediatric trauma center like Texas Children’s Hospital in the Houston Bay Area. We know the terror of the parent at the bedside, watching a surgeon explain that a Salter-Harris Type II fracture of the distal tibia means their eight-year-old’s growth plate may not produce bone correctly for the next decade.
If your family is living through this nightmare in City of La Marque, you likely have the same five words running through your head that Kaitlin Hill shared after her son Colton spent months in a body cast: “We had no idea.”
You had no idea that while the park’s marketing promised “safe family fun,” the facility was operating under a business model that prioritizes throughput and margin over the lives of children. You had no idea that the “Participation Agreement” you signed on a rushed iPad kiosk was drafted by corporate lawyers who knew—in most states—that same waiver wouldn’t hold up in court.
We are here to tell you what the park manager and the insurance adjuster won’t: your child’s injury was not a freak accident. It was the predictable output of a system. And we were built for exactly this fight.
Why Your Case in City of La Marque Is Not an Accident
A trampoline injury in City of La Marque is almost never a random event. It is a business decision that went wrong. Every time a child is launched sideways by a double-bounce or sinks to the concrete floor beneath a compacted foam pit, someone at a corporate office in Grapevine or Dallas made a choice that allowed it to happen.
Maybe the CFO approved a shift-staffing reduction to hit a quarterly target, dropping the court attendant ratio at the park serving City of La Marque effectively to zero. Maybe the operations manager accepted a daily inspection log that was signed by a seventeen-year-old who never actually checked the foam pit depth.
We don’t guess about these things. We prove them.
Our managing partner, Ralph Manginello, brings over 25 years of courtroom experience to every case we handle. Admitted to the U.S. District Court for the Southern District of Texas, he has spent over two decades holding Fortune 500 corporations accountable in complex litigation like the BP Texas City refinery explosion. We treat national trampoline park chains—and the multi-billion-dollar private equity firms like Palladium Equity Partners (backing Sky Zone, Inc.) and Seidler Equity Partners (backing Unleashed Brands and Urban Air)—with the same aggressive discovery discipline we used against BP.
We isn’t just “handling” personal injury cases. We are prosecuting a failure of standards. When a park in the City of La Marque region violates ASTM F2970—the very safety standard the trampoline industry wrote about itself—it isn’t just being careless. It is choosing to operate below its own floor.
The Evidence Clock Is Ticking in City of La Marque
What happens in the next seven days will determine whether your child’s case survives. The trampoline park’s risk management team works weekends. Their insurers have panel law firms. Their systems are engineered to ensure evidence evaporates.
- The 7-to-30-Day Overwrite: Most trampoline park surveillance DVRs are set to overwrite on a cycle as short as one week. If you wait until you are “ready” to call a lawyer, the footage of the Saturday afternoon your child was hurt in City of La Marque is already gone.
- The 72-Hour Kiosk Purge: Kiosk waiver databases often purge version histories on 72-hour rolling cycles. We need to capture the exact version you signed before it is “updated” retroactively.
- The Finalized Report: The original incident report filled out by a monitor at the park near City of La Marque is often “revised” on the corporate server within 48 hours. Our forensic discovery pulls the metadata to find the first, unconditioned version.
Our spoliation letter goes out by certified mail and email within 24 hours of your retention. We don’t just “request” evidence; we demand it with the force of 25 years of trial experience. We stop the DVRs. We freeze the logs. We lock the scene.
Call 1-888-ATTY-911 right now. Hablamos Español. Our associate attorney Lupe Peña used to sit on the other side of the table—defending recreational businesses and insurance carriers. He knows the script the park’s adjuster is going to use when they call you. He knows which waiver clauses are ironclad and which ones are full of holes under Texas law.
Don’t let them push you around with a piece of paper. The waiver is noise. It is not a wall.
The Physics of Failure: Why Trampolines Maim
When you walk into a park like Urban Air or Altitude near City of La Marque, you are entering an environment shaped by extreme energy. The trampoline beds are interconnected, creating a massive surface of shared vibrations. This is the birthplace of the most common catastrophic mechanism: the double-bounce.
If a 200-pound adult lands on a mattress at the same moment a 60-pound child from City of La Marque is pushing off, the energy transfer acts like a catapult. The child’s launch force is multiplied by up to four times. The child isn’t jumping anymore—they are a projectile.
ASTM F2970 Section 10 requires parks to operationalize age and weight separation to prevent exactly this. When a park ignores that rule to get more kids on the court, they aren’t just letting kids have fun. They are gambling with their musculoskeletal systems.
In children, the ligaments are often stronger than the bone. This means force doesn’t just sprain an ankle; it fractures the bone through the physis—the growth plate. A Salter-Harris fracture in a City of La Marque child can lead to a lifetime of orthopedic monitoring. The bone that was supposed to grow for the next six years might not grow at all, or it might grow crooked.
We represent families who are dealing with the reality of those business decisions. As client Chad Harris said about our firm, “You are NOT just some client… You are FAMILY to them.” That is how we treat every City of La Marque parent standing at that bedside.
The Absolute Myth of the Kiosk Waiver in Texas
The most important thing any family in City of La Marque needs to hear is this: You cannot sign away your minor child’s rights in Texas.
The trampoline park wants you to believe that the three seconds you spent clicking “I Agree” at a crowded kiosk ended your child’s legal protection. They are wrong.
In the landmark case Munoz v. II Jaz, Inc. (Tex. App.—Houston [14th Dist.] 1993), Texas courts held that a parent’s pre-injury waiver is unenforceable as to the minor child’s personal cause of action. While the waiver might affect your own derivative claims for medical bills, your child’s right to recover for their pain, suffering, disfigurement, and lifelong impairment remains intact under Texas law.
Furthermore, any waiver in Texas must satisfy the “Fair Notice” doctrine established in Dresser Industries, Inc. v. Page Petroleum, Inc. (Tex. 1993). To be enforceable against an adult, the waiver must be:
- Expressly Clear: It must use the specific word “negligence.”
- Conspicuous: The language must attract the attention of a reasonable person—it cannot be buried in a block of tiny text on a tablet.
If the park near City of La Marque failed either of these tests, or if the person who signed wasn’t the legal guardian (a common occurrence at birthday parties), the waiver fails.
Even in the most defense-friendly jurisdictions, no waiver protects a park from gross negligence. In Harris County, Texas, a jury awarded $11.485 million—including $6 million in punitive damages—against the operator of Cosmic Jump after a teenager fell through a torn slide onto concrete. The jury found that the park had actual knowledge of the risk and showed conscious indifference. This is the Texas anchor for our practice. It is the proof that when you fight, you can win.
Pediatric Injuries: The Road to Recovery for La Marque Families
A serious trampoline injury isn’t just an ER visit. For a family in City of La Marque, it is a multi-year medical and financial gauntlet.
Catastrophic Growth Plate Damage
We look at every pediatric fracture as a potential decade-long medical case. If your child has been diagnosed with a Salter-Harris Type III fracture, they may require an Open Reduction Internal Fixation (ORIF) surgery. Even with perfect surgery, the risk of a “growth arrest” remains until they reach skeletal maturity. Our firm works with life-care planners to calculate what the next ten years of orthopedic monitoring, potential corrective osteotomies, and physical therapy will cost.
Spinal Cord Injury and SCIWORA
The pediatric spine is ligamentously lax. This means a child can suffer a catastrophic cord injury—paralysis—without a single visible bone break on an X-ray. It is called SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). If your child had a head-first foam pit landing and were told they were “fine” because the CT was normal, but their symptoms progressed, the park may be liable for the delay in diagnosis and treatment.
We cite the medical consensus established by the American Academy of Pediatrics (AAP), which has warned against recreational trampoline use since 1999. The AAP’s 2024 literature in Pediatrics shows that 11% of all trampoline park injuries are classified as “significant.” In City of La Marque, those significant injuries require significant representation.
Rhabdomyolysis: The Under-Recognized Kidney Hazard
If your child spent two hours jumping in a heated indoor park near City of La Marque, didn’t drink enough water, and arrives at an ER two days later with dark, cola-colored urine and listlessness—this is a medical emergency.
It is called exertional rhabdomyolysis. Muscle cells rupture under the prolonged plyometric load of jumping, releasing myoglobin into the bloodstream. That myoglobin shuts down the kidneys.
Attorney911 currently litigates a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. We have built the medical litigation architecture for this specific pathology. We know how to document the CK (creatine kinase) levels, we know the nephrology experts, and we know how to prove that the park’s failure to provide hydration or enforce rest breaks is what caused the renal failure.
The Liable Parties: Piercing the Five-Layer Stack
When we build a case for a City of La Marque family, we don’t just sue the local LLC. The money is upstream. We perform a corporate structure archeology on every file.
- The Operator LLC: often undercapitalized with a $1M limit.
- The Franchisee: the multi-unit group that often ignores franchisor safety emails.
- The Franchisor: entities like Sky Zone Franchising LLC or UATP Management LLC (Urban Air) that mandate the rules but fail to audit compliance.
- The Corporate Parent: companies like Sky Zone, Inc. or Unleashed Brands that oversee the entire chain’s risk profile.
- The Private Equity Sponsor: Firms like Palladium Equity or Seidler Equity whose investment committees make the final calls on labor costs and capital expenditures.
We have gone head-to-head with the largest corporations on the planet, including BP after the Texas City disaster. The fleets of corporate lawyers employed by these park conglomerates don’t intimidate us. We make them pay.
La Marque Resident FAQ: What Parents Need to Know
Can I sue if I signed the waiver at an Urban Air or Sky Zone near La Marque?
Yes. As discussed, Texas law is protective of minors. Munoz v. II Jaz is your shield. Furthermore, a 2023 arbitration award in Kansas (Collins v. Urban Air) resulted in $15.6 million after an arbitrator found the waiver was unenforceable due to a “systemic failure” by the park to implement safety changes. Even in arbitration, the waiver is not an absolute barrier.
The park manager said it was a “freak accident.” Is that a defense?
No. An “accident” in a trampoline park is almost always a violation of ASTM F2970. Whether it’s a foam pit that was compacted below the 8-inch specification or an attendant who was on their phone, these are documented breaches of duty.
What should I say to the insurance adjuster?
Nothing. The “friendly adjuster call” is a trap. They want a recorded statement to lock you into a version of events that they can later use to assign “comparative fault” to you or your child. In Texas, if they can prove you were 51% responsible for the injury (e.g., for “failing to supervise”), you recover nothing under CPRC § 33.001. Let us handle the adjuster.
How much does a trampoline injury lawyer cost in La Marque?
Nothing upfront. We work on a contingency fee. We advance every expense—the expensive biomechanical engineers, the pediatric orthopedic surgeons, the life-care planners. If we don’t recover money for you, you don’t owe us a dime.

La Guía en Español: Justicia para su Familia en La Marque
Si su hijo se lesionó en un parque de trampolines cerca de City of La Marque, es comprensible que se sienta confundido y presionado. Muchas de las víctimas son niños de familias hispanohablantes, y los ajustadores de seguros a menudo usan la brecha del lenguaje como una táctica.
Nuestro abogado asociado Lupe Peña es hispanohablante nativo y representa a nuestros clientes directamente — sin intérpretes, sin traductores, sin demoras. Si usted firmó un documento únicamente en inglés y su idioma principal es el español, el caso de Texas Delfingen US-Texas v. Valenzuela puede invalidar esa renuncia de derechos.

Understanding Adjacent Attractions: Go-Karts and More
If your injury happened on a Sky Rider zipline, a climbing wall, or an electric go-kart at a venue like Urban Air, the risk profile is even higher. On December 6, 2025, six-year-old Emma Riddle was killed in an electric go-kart at a Florida Urban Air after a mechanical failure. We track these chain-wide patterns. From Newnan, Georgia to Sugar Land, Texas, the harness failures and mechanical glitches on these “add-on” attractions are systemic.
We don’t accept the “isolated incident” excuse. We subpoena the entire chain’s incident history to show that the park knew the attraction was dangerous and did nothing.
The Life-Care Plan: Building the True Value of Your Case
When we say your child’s case in City of La Marque is worth more than the ER bill, we mean it. We construct a Pediatric Life-Care Plan.
A Salter-Harris fracture at age nine isn’t “just a broken leg.” It requires forecasting every cost for the next 70 years:
- Specialist visits through age 18.
- Corrective surgeries if growth is arrested.
- Orthotics and prosthetic lifts.
- Physical therapy intervals.
- Lost future earning capacity.
Most personal injury firms don’t perform this work. We do. Because a settlement that doesn’t cover your child’s needs at age 35 is a failure.
Wait no longer. Call 1-888-ATTY-911. The case starts today.
