“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.” For Kaitlin “Kati” Hill, describing the moment her three-year-old son Colton’s femur was shattered at a trampoline park, that scream was the end of “family fun” and the beginning of a nightmare. Her story, shared over 240,000 times on social media, resonates with every parent in the City of Houston who has stood in a trauma bay at Texas Children’s Hospital or Children’s Memorial Hermann watching a surgical team stabilize a child’s shattered limb.

In the City of Houston, we see this story repeated with clinical precision. It happened to sixteen-year-old Max Menchaca on the first day of his summer vacation at Cosmic Jump in northwest Harris County. He fell through a tear in a trampoline slide, struck the unpadded concrete floor beneath, and suffered a massive traumatic brain injury. While the park pointed to a signed waiver, our legal system held them accountable. A Harris County jury saw through the “paper shield” and awarded $11.485 million—including $6 million in punitive damages—finding the operator grossly negligent. That remains the largest reported jury verdict of its kind in the United States, and it happened right here in the City of Houston.

At Attorney911, we know that what happened to these children wasn’t a “freak accident.” It was the predictable output of a system that puts profit margins ahead of pediatric safety. For over 25 years, Ralph Manginello has fought these battles against Fortune 500 giants like BP and Walmart. Our team includes Lupe Peña, an attorney who used to sit on the other side of the table defending insurance companies and recreational businesses. He knows their playbook because he helped write it. He knows which waiver clauses in the City of Houston are airtight and which ones are full of holes. If your family is facing the aftermath of a catastrophic landing, we don’t just “handle” your case—we dismantle the system that hurt you.

Call 1-888-ATTY-911 right now. Whether the injury happened at one of the ten Urban Air locations across the City of Houston, a Sky Zone in Cypress, or an Altitude in Sugar Land, the evidence clock is ticking. Surveillance video in these facilities is often overwritten in as little as 7 to 30 days. We send our spoliation letters within 24 hours of being retained to freeze that evidence in place. Hablamos Español. No fee unless we win.

The Standard of Care: Why “Industry Standards” Often Fail Houston Families

When you walk into a commercial jump center along the I-10 corridor or near the West Loop, you likely see signs claiming the facility meets “industry safety standards.” What they don’t tell you is that the primary American standard—ASTM F2970—was written by the trampoline park industry itself. It is a voluntary safety floor, not a mandatory ceiling. In the City of Houston and across Texas, there is no state law requiring trampoline decks to be inspected by a government agency. While the Texas Department of Insurance regulates the Class B inflatable attractions (like bungee tramps or Sky Riders) under Texas Occupations Code Chapter 2151, the trampoline courts themselves are statutorily excluded.

This regulatory vacuum is why we look to international benchmarks like EN ISO 23659:2022. Published in late 2022, this is the mandatory standard across Europe and much of the developed world. It requires rigorous design, construction, and operational protocols that many parks in the City of Houston simply ignore. When a Sky Zone or Urban Air operator tells you they followed the rules, we ask: which rules? The voluntary ones their lobbyist drafted, or the international safety requirements the rest of the world treats as mandatory?

We cite ASTM F2970 and F381 from memory—not because we like technical manuals, but because those standards define the duty of care. When an attendant in a City of Houston park is on their phone instead of enforcing age-separated jumping, they aren’t just being lazy; they are violating the specific attendant-to-jumper ratios required by the very rules the industry promised to follow. When we depose a park’s operations manager, we often find we know their safety standards better than they do.

Our base in the City of Houston allows us to serve families across the state and nationwide with an authority grounded in 25+ years of courtroom experience. 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 treat every pediatric growth plate injury and every spinal cord infarction with the same tenacity we brought to the BP Texas City refinery litigation. The conglomerates behind the big chains—Sky Zone, Inc. (backed by Palladium Equity Partners) and Unleashed Brands (the parent of Urban Air, acquired by Seidler Equity Partners)—hire the most expensive defense firms in the country. That doesn’t intimidate us. We’ve already beaten them.

The Mechanisms of Catastrophe: Physics Doesn’t Negotiate

The most common phrase we hear from parents in the City of Houston is: “They were just jumping.” Trampoline physics, however, transforms a simple jump into a high-velocity impact. The signature injury at parks like DEFY or Get Air is the “double-bounce.” This occurs when a heavier jumper lands on the trampoline mat at the exact moment a lighter jumper is pushing off. The energy transfer from the heavier mass to the lighter one can multiply the launch force by up to 4x. In a split second, a 50-pound child becomes a projectile traveling at speeds their developing musculoskeletal system cannot decelerate.

This double-bounce energy transfer is the primary cause of comminuted femoral shaft fractures—where the strongest bone in a child’s body is shattered into multiple pieces. This is exactly what the American Academy of Pediatrics (AAP) has been warning about since 1999. The AAP’s policy statements, reaffirmed in 2012 and 2019, are clear: trampolines should not be used for routine recreation, and children under six should never be on them. Yet, “Toddler Time” remains a major revenue driver for parks throughout Harris County.

Another severe risk is the “foam pit deception.” Foam pits look soft, but they are often reservoirs for catastrophic injury. If the foam blocks are compacted, degraded, or have bottomed out, a head-first entry doesn’t end in a soft cloud—it ends with the skull striking the hard subfloor. This results in SCIWORA (Spinal Cord Injury Without Radiographic Abnormality), a pediatric-specific condition where the spinal cord is stretched or compressed without a visible bone fracture. A child might leave a City of Houston park with what looks like a “panic attack” or neck stiffness, only to experience progressive paralysis hours later.

We also track the 2024 findings published in the American Journal of Roentgenology showing that up to 1.6% of all pediatric emergency department trauma visits are now trampoline-related. Mechanisms like vertebral artery dissection—a spinal-cord stroke—have gone from rare medical anomalies to documented risks seen in viral cases like that of Elle Yona, whose TikTok rehabilitation journey after a trampoline park stroke reached over 27 million viewers.

If your child is exhibiting symptoms like “cola-colored” or dark urine, severe muscle pain, and vomiting after a session at Launch West Houston or Jumping World, they may be suffering from exertional rhabdomyolysis. This is a life-threatening breakdown of muscle tissue that can cause acute kidney failure. We currently litigate a $10 million lawsuit against the University of Houston involving these exact diagnoses—rhabdo and kidney failure. We know the doctors, we know the science, and we know how to prove that the park’s failure to provide hydration or enforce rest breaks caused your child’s kidneys to shut down.

The 5-Layer Defendant Stack: Going Upstream for Justice

One of the most common insurance tactics used in the City of Houston is the “Policy Limit Shell Game.” An adjuster will call you within 48 hours and claim the park only has a $1 million primary policy, hoping you’ll accept a quick settlement and go away. But in the trampoline industry, the money is almost always upstream. We use a forensic corporate archeology protocol to identify every layer of accountability.

  • The Operator LLC: The local entity appearing on the lease.
  • The Franchisee: The ownership group that may own multiple locations in the City of Houston.
  • The Franchisor: Corporate entities like UATP Management LLC (Urban Air) or Sky Zone Franchising LLC.
  • The Parent Company: Sky Zone, Inc. or Unleashed Brands.
  • The Private Equity Sponsor: The deep pockets like Palladium Equity or Seidler Equity who approve the cost-cutting measures that lead to understaffing.

In a recent Kansas arbitration, Damion Collins v. Urban Air Overland Park, an arbitrator awarded $15.6 million to an adult who became a quadriplegic. Crucially, the franchisor—UATP Management—was held responsible for 40% of that award. The arbitrator found there was a “systemic failure” to implement safety changes. This case is the blueprint we use in the City of Houston to pierce the franchise shield. We also look at the manufacturers of the equipment, such as Ropes Courses, Inc. (implicated in the 20 feet fall of Matthew Lu in Gastonia) and retailers like Walmart (for Bouncepro) or Amazon (for Amazon Basics) who can be held liable as sellers under the Bolger v. Amazon doctrine.

Our associate, Lupe Peña, uses his background in insurance defense to identify these layers before the first deposition. He knows that the primary GL policy is just the floor. Above it sit umbrella and excess layers that can reach $25 million to $100 million or more. We also investigate whether the park misrepresented its safety practices on its insurance application. If the park told its insurer it would maintain a 1:32 monitor ratio but actually ran at 1:60 on a Saturday afternoon, the insurer may have a coverage defense against the park—creating massive settlement pressure that we use as leverage for our clients.

Dismantling the Waiver: Why the Signature Isn’t the End

The #1 reason families in the City of Houston hesitate to call a lawyer is the kiosk waiver they signed at the front desk. The park’s risk management team wants you to believe that paper ended your case before it started. They are wrong. Texas law is clear: a parent cannot sign away a minor child’s personal injury claim. The 1993 case Munoz v. II Jaz Inc. established this as a bedrock of Texas pediatric law. Even for adults, the “Express Negligence Doctrine” from Dresser Industries v. Page Petroleum requires that waiver language must be bold, conspicuous, and specifically state it is releasing “negligence”—it cannot be buried in fine print.

We attack waivers on five distinct vectors:

  1. Gross Negligence: No waiver in Texas can release a party from gross negligence—the conscious indifference to a known extreme risk.
  2. Signer Authority: Many waivers are signed by aunts, grandmothers, or family friends at birthday parties. Under Texas Family Code § 153.073, only a legal guardian has the authority to sign for a child. A non-guardian signature makes the waiver a legal nullity.
  3. Bilingual Formation: Under the Delfingen doctrine, if your family speaks Spanish as their primary language and the park presented an English-only iPad waiver without translation or explanation, we argue that no valid contract was ever formed.
  4. Scope Gaps: The waiver covers “inherent risks.” A torn mat or an improperly secured harness is NOT an inherent risk; it is a maintenance or training failure.
  5. Electronic Execution: We subpoena the kiosk audit logs. If the metadata shows the signature was captured after the child had already started jumping, or if the session timed out, the signature is void.

We don’t take “no” from a claims adjuster. One company told client Donald Wilcox they would not accept his case. Then he got a call from us, and as he said, “I got a call to come pick up this handsome check.” We take the cases that involve the toughest waivers because we know the legal arguments that break them.

The First 48 Hours: Freezing the Evidence Pipeline

When a child is injured at an Urban Air in the Heights or a Sky Zone in Baytown, the park’s risk management team is active before the ambulance sirens fade. We have seen patterns, documented in public reviews at locations like Urban Air Southlake, where managers reportedly instruct staff “to NOT call 911” or tell them to “down-play injuries.” Every minute the park stays in control of the narrative is a minute evidence disappears.

Our City of Houston evidence preservation protocol is aggressive. We demand:

  • Surveillance DVR Hard Drives: These systems overwrite on a rolling cycle. We demand the hardware be pulled and imaged forensic-style using write-blocked acquisition.
  • Incident Report Metadata: We want every version of the report, from the original handwritten notes to the “finalized” version that has been sanitized by corporate lawyers 40 hours later.
  • Attendant Cell Phone Records: We need to know if the monitor responsible for your child’s safety was on TikTok or texting when the impact occurred.
  • Wayback Machine Snapshots: We archive the park’s website and waiver flow immediately to catch any “stealth updates” made after the injury.

We retain the City of Houston-area’s top biomechanical engineers to reconstruct the energy transfer of the fall and pediatric orthopedic surgeons to explain the Salter-Harris growth plate classification of the fracture. As client Angel Walle noted, “They solved in a couple of months what others did nothing about in two years.” We move fast because in a trampoline case, speed equals settlement value.

Pediatric Life-Care Planning: Calculating the True Cost of Recovery

A “broken leg” at age seven in the City of Houston is never just a broken leg. If the fracture crosses the growth plate (the physis), the bone may never grow straight again. This is a Salter-Harris injury, and it can manifest as a permanent limb-length discrepancy that doesn’t fully show up until the child hits their teenage growth spurt five years later.

We build our damages cases using a multi-category Pediatric Life-Care Plan (LCP) that forecasts the next 70 years of needs:

  • Corrective Osteotomies: Future surgeries to realign bones that grew crookedly.
  • Durable Medical Equipment: Prosthetic lifts, custom orthotics, and wheelchair replacements every five years.
  • Future Special Education: Academic remediation for children suffering from cognitive fatigue after a TBI.
  • Lost Earning Capacity: Quantifying how a permanent physical or cognitive limitation will affect your child’s adult career path.
  • Psychological Support: Treating the PTSD that follows a traumatic impact and a months-long body cast.

Most generalist law firms in the City of Houston calculate damages based on the hospital bill. We calculate damages based on the life your child was supposed to have. National industry data shows that for catastrophic pediatric spinal cord or brain injuries, LCPs frequently anchor in the $10 million to $25 million range. We advance every dollar of these expert costs. You pay us nothing unless we recover for you.

Frequently Asked Questions for Houston Families

Can I sue if I signed the electronic waiver at the kiosk?

Yes. In the City of Houston, most parental waivers are unenforceable as a matter of public policy under Munoz v. II Jaz. Furthermore, many kiosk waivers fail the “Fair Notice” guidelines because the text is too small or not sufficiently conspicuous. If the park was grossly negligent—meaning they knew about a danger like a torn mat and didn’t fix it—no waiver in Texas can protect them.

What should I do if the trampoline park manager refuses to call 911?

Call 911 yourself immediately. Pattern evidence across several chains suggests that parks often try to downplay injuries to avoid generating a paper trail or alerting regulators. If a manager delays medical help, that delay is evidence of conscious indifference and supports a claim for punitive damages.

How much is my child’s trampoline park injury case worth?

Every case is different, but settlements and verdicts in this industry vary by the severity of the injury and the strength of the evidence. Harris County saw an $11.485 million verdict for a TBI. National settlements for pediatric fractures with growth plate involvement often range from $500,000 to $2 million. Catastrophic spinal injuries often settle for multi-million dollar amounts to cover lifetime care.

Does it matter if my child was hurt at a birthday party?

Yes. If your child was a guest at a party, it is possible you never signed a waiver yourself, or that the host parent signed “for” your child without legal authority. This creates a significant gap in the park’s defense. Additionally, birthday parties often exceed a park’s safe capacity, making the attendant-to-jumper ratio violations even more glaring.

How long do I have to file a claim in the City of Houston?

The adult personal injury statute of limitations in Texas is generally two years from the date of the accident. For minors, the clock is usually “tolled” (paused) until they turn eighteen, giving them until age twenty. However, you should never wait. The evidence clock is the real deadline. Surveillance video and witness memories can fade in weeks.

Why is rhabdomyolysis an issue at trampoline parks?

Extended physical exertion—especially in hot, humid indoor facilities without adequate water—causes muscle tissue to break down. This muscle death releases myoglobin into the blood, which clogs the kidneys. We are uniquely equipped to handle these cases in the City of Houston because we are actively litigating a $10 million rhabdo case against a university. We know the medical science needed to win.

Complete Guidance for Families in the City of Houston and Beyond

For those dealing with the immediate aftermath of a jump-related tragedy, the most important thing to remember is that this was not your fault. You took your child to a place that advertised “safe family fun.” You trusted that their monitors were trained, their mats were maintained, and their foam pits were deep enough. The failure lies with the multi-million dollar conglomerates that choose margins over monitors.

We represent the parents at the trauma-bay bedside. We represent the child in the body cast. We represent the family facing a lifetime of medical debt they didn’t ask for. We have litigated against some of the largest corporations in the world, including BP after the Texas City refinery disaster. The PE-backed parents of Sky Zone and Urban Air do not bring anything we haven’t beaten before.

If your injury was caused by a defective backyard trampoline—manufactured by Jumpking, Skywalker, or Springfree—we apply the same rigorous discovery protocol. We pull CPSC recall histories and manufacturer design specifications to prove that the net failed because of poor engineering, not your child’s jump.

In the City of Houston, we are surrounded by family entertainment options. But when those options result in permanent disability or wrongful death, the “entertainment” ends and the legal battle begins. We are ready for that battle.

Understanding the Liability Stack in Major Houston Incidents

The Lakhani / Ispahani family at Urban Air Sugar Land provides a stark example of why our multi-layer discovery matters. When that fourteen-year-old girl fell 30 feet because an attendant failed to attach the fall-protection equipment, it wasn’t just a mistake by a teenager. It was a systemic failure of training and supervision mandated by the franchisor. We look at the “Spy Ninjas HQ” Urban Air in Las Vegas where a child fell 20 feet and the “Leap of Faith” fall in Denver to build a pattern of conduct. Under Federal Rule of Evidence 404(b), these prior similar incidents are admissible to prove that the corporate office KNEW their harness protocols were failing across the country and did nothing to fix them.

This “Pattern and Practice” evidence is what transforms an ordinary negligence case into a punitive damages powerhouse. We don’t just sue the local City of Houston park; we sue the system that allowed the injury to become inevitable.

Final Path to Justice

If you lost your child at a trampoline park, or if your child is facing a future of surgical interventions and limited mobility, the most important action you can take is to preserve the truth. DVRs overwrite. Witness lists vanish. Waiver databases are updated to retrofit legal protection.
