In Harris County, Texas, a mother named Kati Hill took her three-year-old son, Colton, to a local trampoline park during a session specifically marketed for small children. She believed the safety netting and padded surfaces were engineered for a toddler. She was wrong. A larger child landed on the same trampoline bed, and the resulting energy transfer snapped Colton’s femur—the strongest bone in the human body. Kati later described the sound in a way that still haunts every parent who hears it: “The worst scream that you could ever have heard from a child.”
What happened to Colton wasn’t a “freak accident.” It was the predictable output of a business decision. At Attorney911, we have spent over 25 years making sure that when corporations put profit ahead of children’s safety, they are held accountable. We represent families in League City and across Texas whose lives have been upended by these facilities.
If your child was injured at a trampoline park in League City, or if a defective backyard trampoline has left your family facing a lifetime of medical bills, you don’t need a generalist lawyer. You need a firm that can quote ASTM F2970 Section 10 from memory, a firm that knows exactly which clauses in the Sky Zone or Urban Air waiver have been voided by Texas courts, and a firm like ours that includes a former insurance-defense attorney, Lupe Peña, who used to write the very arguments these parks use today.
We represent the parents standing at the trauma-bay bedside at Texas Children’s Hospital or Children’s Memorial Hermann watching a surgeon explain what happens when a growth plate is destroyed at age nine. We know the fight you’re in, and we know how to win it.
The Harris County Reality: Cosmic Jump and the $11.485 Million Benchmark
Texas parents are often told that the waiver they signed at the kiosk is an absolute bar to recovery. We’re here to tell you that in Harris County, that is a lie the insurance companies want you to believe.
In a landmark case just a few miles from League City, a sixteen-year-old named Max Menchaca fell through a tear in a trampoline slide at a facility called Cosmic Jump. He plummeted five feet onto unpadded concrete, suffering a skull fracture and a traumatic brain injury. Cosmic Jump pointed to the signed waiver and told the family they had no case.
We know better. A Harris County jury heard the evidence that the park knew about the tear and chose to keep the attraction open to hit a revenue target. The jury found the park grossly negligent and awarded $11.485 million, including $6 million in punitive damages.
That verdict is the largest reported jury award against a U.S. trampoline park, and it happened right here in our backyard. It proves that when we establish gross negligence—which we defines as a conscious disregard for a known risk—that piece of paper you signed at the front desk becomes noise.
Whether the injury happened at the Urban Air on the Gulf Freeway, the Sky Zone in Baytown, or an Altitude facility in Webster, the playbook is the same. We don’t just sue the local LLC; we go upstream to the franchisors like Sky Zone, Inc. and the private equity sponsors like Palladium Equity Partners. We find the money, and we hold the decision-makers accountable.
One Bounce. One bad landing. One broken neck.
The physics of a trampoline injury are brutal. When a 200-pound adult lands on a trampoline bed while a 60-pound child pushes off, the child isn’t jumping anymore—they’ve become a projectile. This “double-bounce” mechanism can multiply the child’s launch force by up to four times.
The American Academy of Pediatrics (AAP) has been warning since 1999 that trampolines are too dangerous for recreational use. ASTM F2970—the safety standard written by the trampoline-park industry itself—requires parks to enforce age and weight separation to prevent exactly this kind of energy transfer. Yet, walk into any park near League City on a Saturday afternoon, and you’ll see a teenager on his phone while toddlers and teenagers bounce on the same interconnected courts.
When that happens, and a child arrives at the emergency room with a comminuted femoral shaft fracture or a Salter-Harris growth plate injury, the park has violated its own industry standard. That isn’t an “inherent risk of trampolining.” It’s negligence.
The Evidence Clock: Why the Next 7 Days Determine Your Case
If your child was injured in League City, the clock isn’t just running on the two-year Texas statute of limitations. It’s running on the evidence.
Most trampoline park DVR systems are set to overwrite surveillance footage in as little as 7 to 30 days. The waiver kiosk’s version-history database may purge on a 72-hour rolling cycle. The teenager who saw the accident might not even work there next month—the industry sees a 130% to 150% annual staff turnover.
Within 24 hours of being retained by a family, we send an aggressive spoliation letter. We demand the preservation of:
- Every camera angle from the 24 hours surrounding the injury.
- The ORIGINAL incident report before it was “revised” by a manager.
- The time-clock records for every attendant on shift.
- The training logs for the specific court monitor assigned to your child’s zone.
- The daily and monthly maintenance logs verifying foam-pit depth and mattress tension.
By the time the insurance adjuster calls you with a “friendly” check-in, our investigators have already begun documenting the scene. We don’t draft from a blank page; our firm uses paralegal-grade scaffolds that have been refined over 25 years to ensure no corporate layer can hide behind a “lost” video file.
Why Your League City Homeowners Policy May Not Protect You
Backyard trampolines are the leading cause of trampoline injuries in League City’s suburban neighborhoods like South Shore Harbour and Victory Lakes. If a neighbor’s child wandered onto your property and was hurt, you may be facing a claim under the Attractive Nuisance Doctrine.
Texas law holds that because trampolines are so attractive to children who cannot appreciate the danger, a homeowner must take reasonable steps to secure them—like locked gates and removed ladders.
But here is the insurance nightmare: Many homeowners’ policies in League City now EXCLUDE trampoline-related injuries entirely. If you have a Jumpking, Skywalker, or a Springfree in your yard and haven’t secured a specific endorsement, you might be bare.
If the trampoline itself failed—if a frame weld broke, or the UV-degraded netting that survived a Houston hurricane season snapped—we pursue the manufacturer under strict product liability. Manufacturers like Jumpking and Skywalker have documented CPSC recall histories for frame failures. We know how to trace the batch and serial numbers to see if your child was the victim of a known defect they failed to recall.
Catastrophic Pediatric Injuries: Beyond the ER Bill
When we talk about a “broken leg” at a trampoline park, we aren’t talking about a simple cast. In children, we are often dealing with Salter-Harris Type II fractures of the distal tibia.
The growth plate is cartilage, not bone. If it’s crushed or severed at age eight, your child’s leg may not grow straight for the next decade. They may face a life of corrective osteotomies, limb-length discrepancies, and chronic pain.
We build a Pediatric Life-Care Plan for every catastrophic case. We retain a team of experts that most generalist firms won’t pay for:
- Biomechanical Engineers to reconstruct the force of the double-bounce.
- Pediatric Orthopedic Surgeons to project the next ten years of growth-plate monitoring.
- Life-Care Planners to quantify the 60-year medical cost of a spinal cord injury.
- Forensic Economists to calculate the lost earning capacity of a child whose developing brain was damaged by a TBI.
Our managing partner, Ralph Manginello, has secured multi-million dollar results for traumatic brain injury and spinal cord injury victims. We advanced those expert costs out of our own pocket because you shouldn’t have to choose between your child’s recovery and a first-class legal team.
The University of Houston Rhabdo Bridge: A Unique Firm Asset
We are currently litigating a $10 million lawsuit involving rhabdomyolysis and acute kidney failure following an exertion incident at a university. This physiology is identical to what we see in “exertional rhabdo” cases at trampoline parks.
Imagine a hot summer day in a League City park. The AC is struggling. A ten-year-old jumps for 90 minutes straight, drinking only soda. Two days later, he is in the ER with dark, cola-colored urine and his kidneys are shutting down.
Most lawyers would call that a “medical issue.” We call it a liability claim. We have the medical experts on speed-dial who understand the myoglobin cascade and how a park’s failure to provide rest intervals or hydration stations breaks the law of premises liability.
Identifying the Liable Parties: Who Really Pays?
When we sue for a trampoline injury in League City, we aren’t just looking at the name on the building. We look at the 5-Layer Defendant Stack:
- The Operator LLC: Often undercapitalized with a $1M policy.
- The Franchisee: The owner of multiple regional locations.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC who mandate the (often inadequate) safety protocols.
- The Corporate Parent: Sky Zone, Inc. (renamed from CircusTrix) or Unleashed Brands.
- The Private Equity Sponsor: Firms like Palladium Equity Partners or Seidler Equity Partners whose pressure for higher margins often leads to lower attendant-to-jumper ratios.
Every insurance layer—primary, umbrella, and excess—gets discovered. We find the “Additional Insured” provisions that link the local park to the billion-dollar corporate tower. If there is money to be found, we will find it.
Texas Waiver Deconstruction: The Paper Shield Fails
The park manager will show you the waiver and tell you that you “assumed the risk.” In League City, that defense is incredibly weak for three reasons:
1. The Munoz Rule: A parent in Texas cannot sign away a minor child’s right to sue for personal injuries. Your signature might bar your own claim for medical bills, but it does NOT bar your child’s claim for their own suffering, impairment, and future losses.
2. The Dresser Doctrine: A waiver must be “conspicuous” and meet the “express negligence” rule. If the word “negligence” isn’t in bold, all-caps, or specifically highlighted, the waiver is often legally void in Texas for failing to give fair notice.
3. The Delfingen Spanish-Formation Attack: In League City’s diverse community, many families speak Spanish as their primary language. If a park employee hurried a Spanish-speaking parent through an English-only iPad waiver at a busy check-in counter, that waiver may be void on formation grounds. Lupe Peña represents our Hablamos Español clients directly, ensuring they are never exploited because of a language gap.
“Can I sue if I signed the waiver at Urban Air?”
Yes. We have successfully bypassed waivers for gross negligence, for minor-child injuries, and for specific failure-to-warn claims. In one case involving a torn mat—identical to the Cosmic Jump mechanism—the waiver was irrelevant once we proved the park knew the equipment was failing.
“What is the average settlement for a child’s broken leg at a jump park?”
There is no “average” because every child’s biology is different. A simple fracture might settle for five figures. A Salter-Harris Type III fracture that requires surgery and results in a permanent growth arrest can reach seven figures. If the injury involves a cervical spinal cord injury (quadriplegia), national verdicts routinely exceed $10 million to $15 million. We fight for the maximum recovery to ensure your child’s lifetime care is fully funded.
“They told me I have to go to arbitration. Is that true?”
After the 2025 Texas Supreme Court ruling in Cerna v. Pearland Urban Air, parks are using “delegation clauses” to try and push every case into a private arbitration room. However, this rule is narrow. We attack the existence of the agreement and the authority of the signer. If someone other than a parent signed—like an aunt, a coach, or a friend’s parent—the arbitration clause typically fails under Texas Family Code § 153.073.
“What if my kid hit their head and the ER said they were fine, but they’re still not acting right?”
This is a major red flag. Pediatric TBI and SCIWORA (Spinal Cord Injury Without Radiographic Abnormality) can present with normal initial CT scans. If your child has persistent headaches, mood changes, or trouble at school in League City ISDs, they need a pediatric-neuropsychological evaluation. We help our families get the right specialists to document the hidden damage that a standard ER misses.
“What should I do if the park manager keeps calling me?”
Stop talking to them. They aren’t trying to help; they’re trying to get a recorded statement. Every “I guess” or “He seemed okay at first” you say will be used in a deposition to minimize your child’s pain. Refer all calls to us.
“Does it cost anything to start my case?”
No. We work entirely on a contingency fee. We pay for the biomechanical engineers, the investigators, and the medical experts. If we don’t recover money for your family, you don’t owe us a dime. Your child’s recovery fund stays 100% intact until the case concludes.

The Kill Shot sequence: Your Case Starts Today
What happened to your child at a League City jump park wasn’t an accident. It was the predictable output of a multi-billion dollar system that assumes a certain number of broken children are an acceptable cost of doing business. The AAP has been warning about them since 1999. The industry wrote ASTM F2970 to give themselves a safety floor, and then most parks chose to operate below it.
Your child’s case depends entirely on what gets preserved this week. The surveillance video will be gone soon. The attendants will quit or transfer. The park’s incident report will be “updated” to blame your child for jumping “wrong.”
We are built for this fight. We have the 25 years of courtroom experience, the federal court admissions, and the internal knowledge to dismantle the waiver at the kiosk and reach the insurance towers above it.
Call 1-888-ATTY-911. Hablamos Español. Our spoliation letter goes out within 24 hours of your call. Don’t let a corporate risk-management team decide what your child’s future is worth. Let us hold them accountable.

Verbatim Parent-Query FAQ Library for League City Families
“Should I take my kid to a trampoline park at all?”
As attorneys who see the worst outcomes, we have a very clear answer: The medical data is terrifying. Peer-reviewed studies in Pediatrics show that jump-park injuries are significantly more severe than backyard injuries and that children under 6 are at a massive disadvantage. If you must go, never allow “mixed-age” jumping and never leave the observation rail.
“My kid broke a bone at the park. What do I do?”
First, ensure they are seeing a dedicated pediatric orthopedic surgeon, not just a generic bone doctor. In Harris County, we recommend reaching out to the specialists at Texas Children’s. Second, do not sign any “incident follow-up” forms or accept free jump passes. Those are often releases in disguise. Call us immediately so we can preserve the video.
“They wouldn’t call 911—is that legal?”
We’ve seen reports from parks like the Urban Air in Southlake where staff were reportedly discouraged from calling 911 to avoid negative attention and corporate reporting. This is a massive breach of the standard of care. If they refused to call for your child, that is conscious indifference and is a cornerstone of our gross-negligence claim.
“Can I sue if someone else’s kid landed on mine?”
Yes. The park has a non-delegable duty to supervise. ASTM F2970 requires “one person per bed” and “monitor supervision.” If the park allowed a 150-pound teenager into the toddler zone, the park is liable for the collision. They cannot blame a child for the park’s failure to supervise.
“Is my kid’s head injury worse than they’re saying?”
Children are master compensators. They can have a vertebral artery dissection or a slow intracranial bleed and look “fine” for 24 hours. If they are vomiting, lethargic, or just “off,” follow the Elle Yona pattern: don’t accept a “panic attack” diagnosis. Ask for an MRI/MRA.
“Will I be blamed for taking them there?”
The park’s lawyer will try. They will point at the waiver and say you knew the risks. Our response is consistent: No parent “assumes the risk” that the park will ignore its own safety monitors or that the foam pit will be unmaintained. The system failed you, not the other way around.
“How much does a trampoline-park lawyer cost?”
At our firm, zero dollars out of pocket. We take all the risk. We advance the $20,000+ it costs for engineering and medical experts. If we don’t win, we don’t get paid. It’s that simple.
“When should we actually call a lawyer?”
If your child required more than basic first aid—if there was a fracture, a concussion, a dislocation, or a server neck strain—you should call today. Every day you wait is a day that Video Recording at the park gets closer to being deleted.
Detailed Mechanism Review for Houston and League City Parks
In our experience with the dense park market in areas like Cypress, Katy, and League City, we have identified specific hazards that families often overlook:
The Foam Pit Fallacy
Fosos de espuma (foam pits) are advertised as soft landing zones. In reality, they are often compact, dirty, and shallow. If the foam hasn’t been rotated or replaced (which ASTM F2970 requires), your child is essentially landing on a concrete floor with a few inches of sponge. This is the mechanism for C1-C7 fractures and permanent paralysis.
The Stunt-Tramp Catapult
Parks often set up basketball dunk lanes. These are high-velocity zones. When multiple kids use the run-up trampoline simultaneously, the rebound energy is unpredictable. We have seen tibial plateau fractures in teenagers that never would have happened on a normal basketball court.
In-Ground “Flush” Trampolines
Parks like Ground Control in DFW use in-ground trampolines. While these eliminate fall-off-the-side risks, they change the “vestibular” experience and can still lead to catastrophic double-bouncing if the beds are interconnected beneath the pads.
The Under-Trained “Monitor”
The most dangerous part of any jump park near League City is the 17-year-old monitor. Research shows these employees often receive less than 4 hours of safety training. They aren’t lifeguards; they are minimum-wage workers with a whistle. If the monitor was on a phone or chatting when your child was hit, we subpoena their personal phone records to prove they weren’t watching the court.
Spanish Language Rights in Texas Parks
DERECHOS DE LAS FAMILIAS HISPANAS EN TEXAS.
Si su idioma principal es el español y el parque solo le proporcionó un waiver en inglés, es posible que ese documento sea inválido bajo la ley de Texas.
