One bounce. One bad landing. One life forever altered.
At the trampoline parks serving the City of Katy, a Saturday afternoon birthday party can turn into a surgical emergency in less than two seconds. You were in the observation area of a park near the Katy Freeway or watching from the sideline of a backyard in Cinco Ranch. You signed the waiver at the kiosk because the line was long and the staff was pressuring you to hurry so the kids could get their wristbands. You believed the advertisements that promised “safe family fun.”
Then you heard it. Kaitlin Hill, a mother whose story went viral after her three-year-old son Colton broke his femur at a park, described it as “the worst scream that you could ever have heard from a child.” At our firm, we hear that scream in every file we open.
We are Attorney911—The Manginello Law Firm. With over 25 years of courtroom experience, our founder Ralph Manginello has spent his career making multi-billion-dollar corporations like BP and Amazon accountable for the catastrophic damage they cause. Our trampoline injury practice is built on a foundation of federal court experience and insider knowledge. Our team includes Lupe Peña, an attorney who used to represent the insurance companies that defend these parks. He knows their playbook because he helped write it. He knows which waiver clauses are built to intimidate you and which ones Texas courts will throw out.
If your child was injured on a trampoline in the City of Katy, you are likely feeling a combination of terror and guilt. You might think that because you signed a digital waiver, you have no rights. You are wrong. In Harris County, a jury awarded $11.485 million against the operator of Cosmic Jump after a teenager fell through a torn slide onto concrete. The waiver was signed. The jury found gross negligence anyway.
What happened to your child wasn’t a “freak accident.” It was the predictable output of a system that puts profit margins ahead of pediatric safety. The clock is already running. The surveillance footage of your child’s injury at a Katy-area park is being overwritten right now. We send spoliation letters within 24 hours of retention to freeze that evidence in place.

The Reality of Trampoline Injuries in the City of Katy
The City of Katy is a hub for youth sports and family-centered recreation. From the elite athletics of Katy ISD to the crowded courts of Urban Air on Kingsland Blvd or the specialized features at Cosmic Air, thousands of Katy children are airborne every single weekend.
While the industry markets these parks as a form of exercise, the medical reality is far grimmer. A 2024 radiographic study published in the American Journal of Roentgenology revealed that up to 1.6% of all pediatric emergency department trauma visits in the United States are now trampoline-related. In a high-growth, family-dense area like the City of Katy, our local trauma centers—including Texas Children’s Hospital West Campus and Memorial Hermann Katy—see the results of these business decisions daily.
Whether the injury occurred at a commercial park or a backyard trampoline in a master-planned community like Seven Meadows or Grand Lakes, the physics of the trauma are identical.
The Myth of the “Accident”
The trampoline industry wants you to believe that injuries are just an inherent risk of jumping. We disagree. The American Academy of Pediatrics (AAP) has formally advised against recreational trampoline use since 1999. They reaffirmed this position in 2012 and again in 2019. For over a quarter-century, the medical community has reached a consensus: trampolines are too dangerous for children.
The parks in the City of Katy know this. The manufacturers of the equipment in your neighbor’s backyard know this. They choose to ignore 25 years of medical warnings because the business model is simply too profitable. When a park violates ASTM F2970—the safety standard the trampoline industry actually wrote for itself—it isn’t an accident. It is a choice.
Why Your Local Katy Park Attraction Failed
Commercial trampoline parks are no longer just rooms full of mats. They have evolved into “Family Entertainment Centers” (FECs) that bolt on increasingly dangerous attractions to maintain their competitive edge. Every new feature added to a park in the City of Katy brings a new way for a child to be maimed.
The Double-Bounce: Physics of a Catapult
The most common mechanism of injury we see in the City of Katy is the double-bounce. This occurs when two people jump on the same trampoline bed. When a heavier person (like an adult or a teenager) lands while a smaller child is pushing off, the kinetic energy from the larger person is transferred through the mat.
The result is a launch force multiplied by up to 4x. The child isn’t jumping anymore; they are being thrown. This energy transfer is the primary cause of “trampoline fractures”—proximal tibial metaphyseal buckle fractures—and shattered femurs. ASTM F2970 requires parks to enforce age and weight separation, but on a busy Saturday in Katy, court monitors rarely intervene.
Foam Pits: The Cervical Danger Zone
Foam pits at parks like Urban Air or Altitude look like clouds, but they often hide a hard floor beneath. Over time, foam cubes compact and lose their ability to absorb impact. If the pit depth falls below the 8-inch specification required by ASTM F2970, a jumper who enters head-first will strike the concrete or wood subfloor.
This axial loading is the mechanism for permanent spinal cord injury and paralysis. We look for the “compaction log” in every foam pit case—an internal record that often reveals the park knew the pit was dangerous for weeks but didn’t want to pay for new foam.
Rhabdomyolysis: The Heat and Exertion Emergency
In the Texas heat, indoor parks in the City of Katy often struggle to maintain safe ambient temperatures. When children jump continuously for 60 to 90 minutes in an 85-degree facility without mandatory hydration breaks, they are at risk for exertional rhabdomyolysis.
Rhabdo is the breakdown of muscle tissue that releases myoglobin into the bloodstream, which then poisons the kidneys. If your child has dark, “cola-colored” urine, severe muscle pain, or vomiting 12 to 48 hours after a park visit, you must go to the ER immediately. Our firm is uniquely qualified to handle these cases because we are currently litigating a $10 million lawsuit against the University of Houston involving this exact pathology. We know the medicine, we know the nephrology experts, and we know how to prove the park’s hydration protocols were negligent.
Harness and Attraction Failures
Adjacent attractions like the Sky Rider zipline-coaster or climbing walls have produced documented strangulation and fall-from-height patterns. In Sugar Land, just a short drive from Katy, a 14-year-old girl fell 30 feet because an attendant failed to attach the fall-protection equipment. These “human errors” are actually systemic training failures. The 17-year-old monitor watching your child may have received only two hours of training before being put in charge of a life-safety harness.
Who Is Really Liable for a Katy Trampoline Injury?
The parent conglomerates behind national chains like Sky Zone, Inc. (formerly CircusTrix), Unleashed Brands (Urban Air), and Altitude Franchise Holdings use complex corporate layering to shield their assets. They hope that if you sue, you will only name the local Katy LLC, which is often undercapitalized and carries a low-limit insurance policy.
We go upstream. The money in these cases is always found in the higher layers:
- The Operator LLC: The entity running the facility on the ground.
- The Franchisee: The ownership group that may own multiple locations.
- The Franchisor: The entity that mandates the (often inadequate) safety and training manuals.
- The Corporate Parent: Private equity sponsors like Palladium Equity Partners or Seidler Equity Partners.
- The Equipment Manufacturer: For designer defects in the mats, springs, or harnesses.
Ralph Manginello and our team have spent 25 years going head-to-head with Fortune 500 companies. We are not intimidated by the private equity lawyers defending these chains. We trace the corporate archeology to find the deep-pocket insurance layers—primary GL, umbrella, and franchisor excess coverage—that are necessary to pay for a lifetime of pediatric care.
The Waiver Defense: Why the Paper Doesn’t Protect the Park
The most common question we hear from parents in the City of Katy is: “I signed the waiver on the iPad, so I don’t have a case, right?”
In Texas, the answer is often no. A signed waiver isn’t a wall; it’s a speed bump.
The Gross Negligence Carve-Out
Under Texas law (settled in cases like Moriel and Storey), a waiver cannot release a defendant from gross negligence. If a park in Katy knew a piece of equipment was torn and kept it in service, or if they knowingly operated at dangerously low staffing levels to save money on a holiday weekend, they have shown conscious indifference. The $11.485 million Cosmic Jump verdict in Harris County proved that jurors will punish parks for this conduct, regardless of what was signed at the front desk.
The Munoz Doctrine: Protecting Katy Children
The landmark case Munoz v. II Jaz, Inc. (1993) established that in Texas, a parent generally cannot sign away a minor child’s right to sue for personal injuries. Your signature might bar your individual claims for medical bills you’ve already paid, but it does not stop your child from seeking justice for their own pain, suffering, and permanent impairment.
The Delfingen Challenge for Spanish-Speaking Families
Texas is a bilingual state, and the City of Katy has a vibrant Hispanic community. If the park presented you with an English-only waiver on a screen but your primary language is Spanish—and they didn’t offer a translation or explain the terms—that waiver may be void. The Delfingen doctrine allows us to challenge waivers signed by families who were not given a meaningful opportunity to understand what they were signing. Lupe Peña speaks your language and can help you navigate this specific defense.
How We Build Your Child’s Case for Maximum Recovery
Most personal injury firms handle a trampoline case like a simple slip-and-fall. They send a letter, wait for an offer, and settle for the first $100,000 policy they find. We do not.
We build every file for a nuclear verdict. Our 10-step case-build includes:
- 24-Hour Spoliation: We demand the preservation of DVR footage, incident-report metadata, and kiosk audit trails.
- Biomechanical Analysis: We retain engineers to model the energy transfer of the double-bounce that launched your child.
- ASTM Compliance Audit: We read the park’s internal logs against the ASTM F2970 standard to prove precisely where they cut corners.
- Pediatric Life-Care Planning: For catastrophic injuries, we work with specialists to project the next 70 years of medical costs, from hardware removals to corrective orthopedic surgeries.
- Digital Waivers Archaeology: We use tools like the Wayback Machine to pull historical versions of the park’s website and contracts to prove they keep modifying their safety claims.
As our client Chad Harris noted, at our firm: “You are NOT just some client… You are FAMILY to them.” We represent the parent who is worried about how they will pay for surgery next month and whether their child will ever walk without a limp.
Specific Injury Mechanisms Seen in Katy Parks
If you are reading this from a hospital or after a follow-up appointment, you need to understand the technical medical terms in your child’s chart. These terms drive the value of your case.
Salter-Harris Growth Plate Fractures
Because a child’s bones are still growing, a break often occurs in the growth plate (physis). A Salter-Harris injury at age nine can produce a leg-length discrepancy that doesn’t fully show up until age fourteen. If your lawyer doesn’t understand the “Salter-Harris” classification, they are leaving millions of dollars on the table. We ensure your child is monitored by top-tier pediatric orthopedic surgeons through skeletal maturity.
SCIWORA: The Invisible Spinal Injury
Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) is a pediatric phenomenon where the spinal cord is damaged even though the bones look “normal” on a CT scan. This happens because children’s spines are more flexible than their cords. If a Katy park attendant told your child to “just walk it off” after a neck strike, and their condition worsened hours later, that is a case for gross negligence based on a failure to invoke proper emergency protocols.
Traumatic Brain Injury and DAI
A head impact on a frame or concrete subfloor can cause Diffuse Axonal Injury (DAI)—the shearing of brain fibers. These injuries often have a “normal” initial CT presentation but result in lifelong cognitive regression, academic struggles, and behavioral shifts. We retain pediatric neuropsychologists to establish the “before” and “after” for your child’s developing brain.
Frequently Asked Questions for Katy Parents
Can I sue if I signed the waiver at an Urban Air or Sky Zone in Katy?
Yes. In Texas, a parent’s signature generally cannot waive a minor’s personal cause of action (Munoz). Furthermore, no waiver in Texas covers gross negligence or conscious indifference. If the park violated safety standards, the waiver is not a wall.
What should I do if the park manager won’t give me the incident report?
This is a standard industry tactic. They are trying to hide internal admissions of fault. We use Texas Rule 202 pre-suit petitions to compel the production of documents and video even before a lawsuit is officially filed.
The park only has a $1 million policy. How will that cover a life-care plan?
The $1 million is only the first layer. We dig through the corporate stack to find the franchisee’s umbrella, the franchisor’s excess towers, and the commercial product-liability policies of the attraction manufacturers. For major chains, the total coverage can reach $25 million to $100 million.
How much does a trampoline park lawyer cost in Katy?
We work on a contingency fee. You pay us nothing upfront. We advance all investigation costs, including the thousands of dollars required for engineering experts and life-care planners. We only get paid a percentage of the money we recover for you.
Why is the insurance company offering to pay my medical bills so quickly?
This is the “Med-Pay” trap. They offer a few thousand dollars to cover your immediate co-pays in exchange for you signing a “final release.” If you sign that paper, you lose the right to sue for the millions of dollars your child’s future care may actually cost. Never sign anything before talking to us.
My child was hurt at a friend’s backyard birthday party. Do I have to sue my friend?
A lawsuit is typically filed against the homeowner’s insurance policy, not the family individually. We also investigate the trampoline manufacturer (Jumpking, Skywalker, etc.) for product defects such as frame-weld failures or UV-degraded netting that failed to stop a fall.
How long do I have to file a claim in Texas?
The standard statute of limitations is two years from the date of injury. For minors, the clock is “tolled” until they turn eighteen, effectively giving them until their twentieth birthday. However, you should never wait. Physical evidence vanishes, and witnesses move away. You need to preserve the case this week, not next year.
Why Katy Families Choose Attorney911
We represent families. We represent children. We represent the parent standing at a hospital bed watching a surgeon explain that a growth plate was destroyed at age nine.
Ralph Manginello’s 25 years of experience means we don’t have to guess when we take a deposition. We know which corner of the operations manual to look at. We know why the park’s surveillance video “glitched” at the exact moment of impact (a pattern we call the Mathew Knight pattern). We know how to take apart the “friendly adjuster” call.
Our offices in Houston, Austin, and Beaumont allow us to handle cases throughout the City of Katy and across the state. Whether you are dealing with a broken femur, a traumatic brain injury, or the dark urine of rhabdomyolysis, we have the medical experts and the corporate-accountability playbook to win.
One company told our client Donald Wilcox they would not accept his case. “Then I got a call from Manginello… I got a call to come pick up this handsome check.” We take the difficult cases other firms decline because they are afraid of the waiver. We aren’t afraid. We wrote the book on how to defeat it.
The Case Starts Today
What happened to your child at a Katy trampoline park wasn’t an accident. It was the predictable output of a system designed to protect a margin. The AAP has been warning about these hazards since 1999. The industry wrote ASTM F2970 to create a safety floor, then chose to operate below it. The waiver was drafted by lawyers who count on you being too intimidated to call us.
Your child’s case is decided by what gets preserved this week. By day 30, the attendant will have a different job. By day 10, the DVR will have overwritten the evidence.

Detailed Local Analysis: Katy Parks and Backyard Standards
The City of Katy is uniquely situated. The high density of “mega-parks” along the I-10 corridor creates a competitive pressure that directly impacts safety. When three different chains are competing for the same birthday-party business, they often cut staff or increase jumper capacity to hit revenue targets.
The Katy “Toddler Time” Risk
Katy parents often visit parks during specialized morning sessions. But many facilities fail to truly segregate these areas. Allowing a ten-year-old on a toddler court—even for a few seconds—creates the mass-ratio energy transfer that breaks bones. If your child was hurt during a “session” that was supposed to be safe for their age, that’s not just negligence; it’s a breach of the park’s specific promise to you.
Backyard Equipment in Master-Planned Communities
In communities like Cinco Ranch and Fulshear/Katy, backyard trampolines stay in the sun for years. The Gulf Coast humidity and UV index degrade polypropylene netting until it becomes brittle. If a neighbor’s net gave out when your child fell against it, we investigate whether the manufacturer provided adequate “end of life” warnings for the product. Many manufacturers, including mass-market brands like Jumpking or Skywalker, provide vague advice in the owner’s manual that few parents read. We hold them to the strict standards of ASTM F381.
The Adjacent Attraction Problem: Laser Tag, Ninja, and Walls
Parks in Katy are pivoting away from trampolines and toward FEC features. Each one adds a liability layer.
- Sky Rider Ziplines: A strangulation hazard if the harness cord is too long or unmonitored.
- Warped Walls: Concussion hazards if children are not spotting one another correctly.
- Krave Bar / Alcohol Service: Some Katy-area FECs now serve alcohol. Mixing adults who have been drinking with children jumping at high velocity is a recipe for catastrophic collision. We look at the “dram shop” liability if an intoxicated adult caused your child’s injury.
Legal and Regulatory Posture in Texas 2025–2026
The jurisdictional split is expanding. While Pennsylvania and New Jersey courts are moving to protect minors from being forced into arbitration, the Texas Supreme Court issued its ruling in Cerna v. Pearland Urban Air in May 2025. This decision allows parks to use “delegation clauses” to send disputes about the waiver’s validity to an arbitrator rather than a judge.
BUT HERE IS THE CAVEAT: Even in arbitration, the law of Munoz and the Dresser fair-notice doctrine still apply. A skilled advocate like the attorneys at Attorney911 can defeat a waiver inside an arbitration room just as effectively as in a courthouse. Damion Collins won $15.6 million in an Urban Air arbitration because his legal team established a “systemic failure” by the company. We are built for both tracks.
We advanced every expert on that list:
- Biomechanical Engineer to prove the catapult effect.
- ASTM Compliance Expert to cite the exact violations.
- Life Care Planner to project the 7-figure lifetime cost.
- Forensic Digitalist to pull the kiosk metadata.
Don’t let a corporate conglomerate tell you your child’s life is worth a $100 waiver cap. They are wrong.
