“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.”
That is Kaitlin hill, a mother who spoke to ABC news after her three-year-old son, Colton, suffered a broken femur at a trampoline park. Her warning, shared hundreds of thousands of times across the country, is the silent echo in the mind of every parent sitting in a waiting room at University Hospital in San Antonio or Methodist Children’s after a Saturday afternoon in City of Castle Hills went catastrophically wrong.
If you are reading this now, it is likely because that scream—or the sickening silence that follows a head-first landing in a foam pit—is still ringing in your ears. You are looking for answers in the middle of the night. You signed a waiver at a kiosk on NW Military Highway or near Loop 410. You were told the park was a “safe place for family fun.” Now, your child is facing surgery, a body cast, or a lifetime of neurological monitoring, and the park’s insurance adjuster is calling to offer you a “friendly” settlement that wouldn’t cover the first day of ICU care.
At Attorney911, we know exactly what is happening behind the scenes. We know because our managing partner, Ralph Manginello, has spent over 25 years making corporate defendants pay for the damage they cause. We know because our team includes Lupe Peña, an attorney who used to sit on the other side of the table, defending the very same insurance companies and recreational facilities we now fight. He knows their playbook because he helped write it. And we know because we are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure—the exact same muscle-and-organ breakdown that we see in children who spend two hours jumping without breaks in a heated indoor park in City of Castle Hills.
What happened to your family wasn’t an accident. It was the predictable result of a business model that prioritizes throughput and profit margins over the safety of your child. We are here to tell you that the paper you signed at the front desk is not a wall. It is a hurdle, and we know exactly how to clear it.
One Jump. One Bad Landing. One Life Forever Changed.
Trampoline park injuries in City of Castle Hills are a growing pediatric trauma category. Nationally, these facilities send more than 300,000 Americans to the emergency room every year. The American Journal of Roentgenology reported in 2024 that up to 1.6% of all pediatric emergency department trauma visits are now trampoline-related.
In City of Castle Hills, neighborhoods like those near West Avenue or the estates along Lockhill-Selma are filled with active families. On any given weekend, hundreds of local children are airborne at parks across the San Antonio metro area. But the physics of a trampoline don’t negotiate with a child’s developing skeleton. When a 200-pound adult lands on a trampoline bed at the same instant an 80-pound child from City of Castle Hills is pushing off, the energy transfer can multiply that child’s launch force by four times. The child isn’t jumping anymore—they are a projectile.
The result is often a “trampoline fracture”—a proximal tibial metaphyseal buckle fracture—or, worse, a Salter-Harris growth plate injury. A break through a growth plate at age seven isn’t just a “broken leg.” It is a decade of orthopedic monitoring, potential corrective surgeries, and a leg that may never grow straight.
Why Your City of Castle Hills Trampoline Injury Case is Decided This Week
The most critical thing you need to understand is the evidence clock. While you are focusing on your child’s recovery, the park is focusing on their risk management.
Trampoline park surveillance DVR systems in the City of Castle Hills area are typically set to overwrite in as little as 7 to 30 days. The incident report that was filled out the night your child was hurt is already being “finalized”—which in many cases means it is being revised by corporate risk managers to shift the blame to you or your child. The waiver kiosk database, which holds the metadata of the version you “signed” under pressure while a line of families waited behind you, might be purged on a 72-hour rolling cycle.
We do not wait for the park to do the right thing. Our spoliation letters go out by certified mail within 24 hours of being retained. We demand the preservation of every camera angle, every version of the incident report, the shift logs of the court monitors, and the maintenance records of the specific attraction that failed your child.

The Systemic Failure of Trampoline Parks in Texas
Texas families deserve to know that they are operating in a regulatory vacuum. Texas is one of the states with zero statewide trampoline park safety acts. There is no state licensing. There is no mandatory state inspection. There is no requirement for these parks to report injuries to a government body.
Compare this to the international standard, EN ISO 23659:2022, which imposes mandatory safety requirements across Europe. Or even other U.S. states like Colorado and New York, which have incorporated ASTM F2970 into their state regulations. In Texas, and specifically for families in City of Castle Hills, you are relying entirely on a standard the trampoline industry wrote about itself—and then chose to follow only when it was convenient for the bottom line.
The Myth of the “Inherent Risk”
When the adjuster calls you, they will use the words “inherent risk.” They want you to believe that breaking a spine or shattering a femur is just “part of the game.”
That is a lie.
An “inherent risk” is an awkward landing on a well-maintained mat with proper supervision. It is NOT an inherent risk for a foam pit to be compacted to four inches when the industry standard requires eight. It is NOT an inherent risk for a harness to be unattached on a climbing wall because a 17-year-old monitor was on his phone. It is NOT an inherent risk for a park to allow a 220-pound jumper on the same court as your 50-pound child.
In Harris County, a jury awarded $11.485 million against the operator of Cosmic Jump after a 16-year-old fell through a torn trampoline slide onto bare concrete and suffered a traumatic brain injury. The park had a signed waiver. They argued “inherent risk.” The jury found gross negligence—a conscious indifference to a known risk—and awarded $6 million in punitive damages specifically to punish the park for that choice.
We bring that same fighter’s mentality to every case we take in City of Castle Hills. Whether you were hurt at a major chain like Sky Zone, Urban Air, or Altitude, or an independent local park, we know how to pierce the corporate layers to find the accountability your family is owed.
Anatomy of an Accident: How These Injuries Actually Happen
If your child was injured in City of Castle Hills, the mechanism of that injury is the first thing our experts will reconstruct. We don’t just “handle cases.” We retain biomechanical engineers to model the energy transfer. We hire pediatric orthopedic consultants who can explain to a jury why a child’s bones fail differently than an adult’s.
The Double-Bounce: A Catapult for Children
This is the signature injury of the modern jump park. When two people of different weights jump on the same mat, the heavier jumper’s landing creates a massive rebound force for the lighter jumper. ASTM F2970 requires parks to enforce age and weight separation, yet on a Saturday afternoon in City of Castle Hills, these rules are routinely ignored to keep the courts full. If your child was “double-bounced,” the park didn’t just have an accident—they violated their own safety standard.
Foam Pits: The Hidden Catastrophe
Fosos de espuma (foam pits) look soft to a parent. They aren’t. If the foam blocks are old, compressed, or haven’t been properly “fluffed,” your child is essentially jumping into a shallow grave of polyurethane. Head-first or feet-first entries into inadequately maintained pits lead to cervical spine injuries, calcaneal (heel) fractures, and SCIWORA—spinal cord injury without radiographic abnormality. This is a pediatric-specific condition where the spinal cord is stretched and damaged even though the bones look fine on an initial X-ray. By the time the symptoms manifest, the damage may be permanent.
Harness and Attraction Failures
As parks in the City of Castle Hills area attempt to become “adventure centers,” they are bolting on ziplines, climbing walls, and ropes courses. We have seen cases like the one in Sugar Land where a 14-year-old fell 30 feet because an attendant simply forgot to attach the safety line. These are not “trampoline risks.” These are staffing and training failures.
Exertional Rhabdomyolysis: The Invisible Emergency
This is the under-reported crisis of the industry. A child jumps for 90 minutes straight in an indoor facility in the Texas heat with only a sugary soda to drink. Twenty-four hours later, they have dark-brown urine and severe muscle pain. Their kidneys are failing because their muscle tissue has literally begun to liquefy.
If your child is experiencing these symptoms after a visit to a park near City of Castle Hills, get them to a Level 1 pediatric trauma center like University Hospital immediately. Then call us. We are the only firm in Texas with a currently active $10 million medical-litigation architecture specifically for rhabdomyolysis cases.
Why the Waiver is Noise, Not a Wall
“But I signed a waiver.”
We hear this from almost every family in City of Castle Hills that calls us. Here is what the insurance companies don’t want you to know: Texas law, and specifically the 14th Court of Appeals in Munoz v. II Jaz, Inc., makes it clear that a parent cannot pre-emptively waive a minor child’s personal injury claim in many contexts.
Furthermore, the Texas “Fair Notice” doctrine requires waivers to be conspicuous and explicitly use the word “negligence.” If the waiver was buried in a tiny font on a screen that you had to scroll through in ten seconds, it may be legally worthless.
Our associate attorney, Lupe Peña, spent years defending these waivers. He knows which clauses are full of holes. He knows which ones Texas courts have already voided for gross negligence. When you hire us, you are hiring that insider knowledge. That piece of paper you signed at the park near City of Castle Hills is just the beginning of our argument, not the end of your case.
Who is Really Responsible?
When we sue a park, we don’t just look at the local LLC. We look at the entire 5-layer defendant stack:
- The Operator LLC: The immediate business on the lease.
- The Franchisee: The multi-unit group that owns the local park.
- The Franchisor: National entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings.
- The Parent Corporation: The private equity-backed conglomerates like Sky Zone, Inc. (formerly CircusTrix) or Unleashed Brands.
- The Manufacturer: The companies that built the defective nets, mats, or harnesses.
In a 2023 arbitration award against Urban Air in Overland Park, a father who was paralyzed was awarded $15.6 million. The franchisor, UATP Management LLC, was found responsible for 40% of the fault because of a “systemic failure” to implement safety changes. We go upstream because that is where the deep pockets and the real accountability live.
Frequently Asked Questions for City of Castle Hills Families
Q: How much does a trampoline park lawyer cost?
A: At Attorney911, it costs you nothing upfront. we work on a contingency fee basis. We advance all the costs—the biomechanical engineers, the pediatric surgeons, the life-care planners. If we don’t win, you don’t owe us a dime. Your child’s recovery fund stays intact.
Q: How long do I have to sue in Texas?
A: The statute of limitations for personal injury in Texas is generally two years. However, for a minor in City of Castle Hills, that clock is “tolled” until they turn 18. This gives the child until age 20 to file. But remember: while the law gives you time, the evidence does not. Surveillance video is gone in weeks. You must act now to preserve the case.
Q: Can I sue if my child was hurt on a neighbor’s backyard trampoline in City of Castle Hills?
A: Yes. Texas recognizes the “Attractive Nuisance” doctrine. If a homeowner has a trampoline that attracts neighborhood children and fails to secure it or supervise its use, they—and their homeowners’ insurance—can be held liable. We routinely navigate the complexities of homeowners’ insurance exclusions to find coverage for injured children.
Q: What if the park offered to pay our medical bills?
A: Be extremely careful. This is often “Med-Pay” coverage. The insurer sends a small check, but the fine print on the back or an enclosed release form might waive your entire right to sue for the millions of dollars in future care your child may actually need. Never deposit a check from a park’s insurer without having us read it first.
Q: My child was hurt at a Sky Zone in San Antonio, but the waiver says we have to go to arbitration. Is that true?
A: While the Texas Supreme Court issued a pro-defendant ruling on “delegation clauses” in 2025 (Cerna v. Pearland Urban Air), arbitration is not a dead end. We have seen arbitrators strike waivers and award millions (see the Damion Collins $15.6M award). Arbitration requires a specific tactical approach that is different from a jury trial. We are built for both.

Every parent who has ever taken a child to a trampoline park near City of Castle Hills has felt that twinge of guilt after an injury. “I should have watched closer,” “I shouldn’t have let them go.”
Stop.
You paid for a ticket. The park accepted your money in exchange for a duty to provide a facility that met industry safety standards.

Detailed Guide: Understanding Trampoline Park Hazards in the San Antonio Metro
City of Castle Hills is unique—a community where neighbors know each other, and local parks are the heartbeat of weekend life. But when you venture out to the major commercial hubs surrounding us, the environment changes. Parks like Urban Air NW San Antonio on Bandera Road or Altitude on IH-10 handle thousands of jumpers. The sheer volume makes staffing lapses inevitable without a radical commitment to safety.
The Problem with “Toddler Time”
Many City of Castle Hills parents take advantage of morning sessions reserved for small children. But across the industry, we see a pattern where “sessions” are not strictly enforced. An older sibling or a teenager from a previous session stays on the court, or the park allows a “all-ages” jump to spill over. Because of Nysted’s physics, a 3-year-old on a court with a 12-year-old is in a danger zone the moment they are within one mat-length of each other.
The American Academy of Pediatrics has been clear since 1999: trampolines do not belong in home or recreational settings for children. When a park markets to toddlers in City of Castle Hills, they are affirmatively inviting a population that their own medical experts have told them cannot jump safely.
The “Don’t Call 911” Protocol
This isn’t just a rumor. Across multiple chains, including Urban Air and Sky Zone, we have seen reports of management instructing staff to “downplay” injuries. They offer ice. They offer a seat on a bench. They wait for you to leave the premises.
Why? Because the moment a 911 call is placed, it creates a public record. It creates an EMS run sheet. It creates a timestamp that cannot be erased. By delaying the call, the park buys time. They hope you’ll drive to an urgent care yourself, leaving no official record at the facility of how the injury happened or what the monitors were doing at that moment.
If you are at a park near City of Castle Hills and your child is hurt, DO NOT ASK permission to call 911. Make the call.
What is Your Child’s Case Worth?
This is the question every family in City of Castle Hills eventually asks. The answer depends on the long-tail damage.
- Economic Damages: Past and future medical bills, the cost of a pediatric life-care plan, and “Lost Earning Capacity”—calculating how much less your child will earn over their 60-year working life because of a brain injury or permanent physical impairment.
- Non-Economic Damages: Pain and suffering, mental anguish, and the “Loss of Enjoyment of Life.” For a child in City of Castle Hills who will never play soccer or dance again, these are the most significant damages.
- Punitive Damages: In Texas, if we prove gross negligence—like the $6M awarded in the Cosmic Jump case—the jury can award extra money specifically to punish the corporation.
We use forensic economists and life-care planners to ensure that the number we demand from the insurer isn’t just a guess. It is a forensic calculation of what it will take to make your child whole until they are 80 years old.
Your Legal Rights in Bexar County
The judicial system serving the City of Castle Hills area is known for juries that value family safety and corporate accountability. If we file your case in San Antonio, the park’s insurer knows they are facing a jury pool that does not tolerate those who gamble with children’s lives.
Our firm is based in Texas. Our managing partner, Ralph Manginello, is admitted to the Southern District of Texas. We know the local court rules, we know the local judges, and we have a reputation for being relentless. We litigated the BP Texas City refinery explosion; we are currently litigating against the University of Houston. We don’t get intimidated by the “big city” defense firms hired by the parent corporations of these parks.
Why You Need an Attorney Who Memorized ASTM F2970
Most personal injury firms can’t tell you what ASTM F2970 requires of a trampoline park. We can cite it from memory:
- Section 10: Requirements for court monitor training.
- Section 8: Specifications for foam pit depth and cushion density.
- Section 13: Daily inspection protocols.
When we depose the park’s operations manager, we know their safety manual better than they do. We find the gaps between what they promised in their franchise agreement and what they actually did on the day your family from City of Castle Hills walked through their doors.

Understanding the Risks of “Glow Night” and Extreme Events
In City of Castle Hills, teenagers look forward to the local “Glow Nights”—events where the lights are replaced by blacklights and high-decibel music. These events are an operational disaster.
- Visibility: Blacklights create high contrast but destroy depth perception. A jumper cannot accurately judge the distance to the edge of a mat or the bottom of an airbag.
- Supervision: It is physically impossible for a monitor to see 50 jumpers in a dark room.
- Staffing: Parks rarely increase their monitor-to-jumper ratio for these high-risk events.
If your child was injured during a specialized event at a park near City of Castle Hills, we look at the specific lighting levels and noise decibels. Most parks fail even their own event-safety protocols.
The Role of Private Equity in Your Child’s Injury
Many City of Castle Hills families are surprised to learn that the park in their neighborhood is actually owned by a multi-billion dollar private equity firm in New York or California.
- Unleashed Brands (Urban Air) is backed by Seidler Equity Partners.
- Sky Zone/DEFY is backed by Palladium Equity Partners.
Why does this matter? Because private equity firms are driven by “EBITDA”—earnings before interest, taxes, depreciation, and amortization. When a PE firm takes over a chain, the first thing they often do is “optimize” labor costs. In plain English, that means fewer monitors and less training. When we sue, we find the internal memos where these cost-cutting decisions were made. We prove that the bone your child broke in City of Castle Hills was the direct price of a margin-target decision made in a boardroom thousands of miles away.
Final Kill-Shot: The Attorney911 Difference
What happened in City of Castle Hills wasn’t an accident—it was the predictable output of a system. The AAP has been warning since 1999. ASTM F2970 was written by the industry itself to establish a safety floor. The park operated below that floor to hit a margin target. The waiver was drafted by corporate counsel who knew it wouldn’t hold in most states. The surveillance is engineered to overwrite before most families have a lawyer.
We were built for exactly this fight.
