The Complete Guide to Trampoline Park and Backyard Trampoline Injuries in the City of Alamo Heights
One bounce. One bad landing. One broken neck. That is all it takes for a family afternoon in the City of Alamo Heights to transform into a lifetime of medical monitoring and forensic-economic calculations. When your child is airborne at a trampoline park, they aren’t just playing; they are operating within a high-energy environment governed by complex physics and, all too often, by corporate business decisions that prioritize margin over the safety floor set by the industry itself. If your child comes off a court on a stretcher and the operations manager hands you a clipboard instead of calling 911, you don’t need an attorney who simply “handles personal injury.” You need a legal team that can quote ASTM F2970 from memory, who knows exactly which clauses in an Urban Air or Sky Zone waiver have been voided by Texas courts, and who has spent 25 years making multi-billion-dollar corporations accountable.
We are Attorney911, and we represent families. We represent the parent standing at the bedside in a San Antonio trauma bay, watching a surgeon explain what happens when a growth plate is destroyed at age nine. Since 1998, our managing partner Ralph Manginello has fought for catastrophic injury victims in federal and state courts, taking on Fortune 500 giants like BP, Walmart, and Amazon. Our team includes Lupe Peña, an attorney who used to sit on the other side of the table—defending trampoline parks and insurance companies. He knows their playbook because he helped write it. Now, he uses that “insider” knowledge to dismantle the very waivers and defense tactics he once deployed. We are the firm that sees through the corporate shields of private equity-backed chains like Sky Zone, Inc. and Unleashed Brands. We are based in Texas, we know the Bexar County courts, and we understand that in a community like the City of Alamo Heights, your child’s future is not a negotiable asset.
Prologue: The Bexar County Reality
Imagine a Saturday afternoon along the 281 corridor or near Loop 410. The City of Alamo Heights is a hub of active families, high-performing student-athletes, and backyard recreational spaces. From the birthday party buyouts at The Rush Fun Park or Urban Air to the Springfree and Jumpking trampolines in the well-manicured backyards of our neighborhoods, the risk is constant.
As Kaitlin “Kati” Hill told ABC News after her three-year-old son Colton’s femur was shattered at a park: “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.” Colton spent months in a body cast. His mother’s warning was shared over 240,000 times. We have read that warning, and we have seen the same mechanism play out in dozens of cases across Texas. Whether it was the $11.485 million verdict in Harris County against Cosmic Jump after a teenager fell through a torn mat onto concrete, or the $15.6 million award against Urban Air in a quadriplegia case, the pattern is systemic. The City of Alamo Heights families deserve to know that the waiver signed at a kiosk is not the end of their story—it is just the first layer of a corporate defense we were built to pierce.
Why Trampoline Injuries Are Never “Accidents”
In the legal world, an accident is an event that could not have been foreseen or prevented. A trampoline injury, by contrast, is almost always the predictable output of a system. The American Academy of Pediatrics (AAP) has formally advised against recreational trampoline use since 1999—a position they reaffirmed in 2012 and 2019. That is twenty-five years of pediatric medical consensus. When a park operator in the San Antonio metro area chooses to ignore that consensus, they are making a business decision to accept a known risk on behalf of your child.
The Physics of the Double-Bounce
The most common mechanism of injury in City of Alamo Heights parks is the double-bounce. This isn’t just “jumping together”; it is a massive transfer of kinetic energy. When a 200-pound adult lands on a trampoline bed at the same instant a 60-pound child is pushing off it, the energy transfer multiplies the child’s launch force by up to 4x. The child isn’t jumping anymore—they are being thrown by a catapult. This is why ASTM F2970 requires parks to enforce age and weight separation. When a park fails to staff enough court monitors to catch an adult jumping with a toddler, they aren’t just being “sloppy.” They are violating the industry’s own safety standard to save on labor costs.
The Failure of Industry Standards
ASTM F2970 was drafted by the trampoline park industry itself. It was meant to be the floor, the minimum safety requirement for attendant-to-jumper ratios, foam pit depth, and equipment inspection. Yet, in Texas, these standards are largely voluntary. We have no statewide trampoline park safety act, unlike Arizona which passed “Ty’s Law” after the death of Ty Thomasson in a shallow 2-foot-8-inch foam pit. Because Texas is unregulated, the only thing keeping your child safe is the operator’s willingness to follow a standard they aren’t legally required to meet—until we involve the courts.
The Liable Parties: Who is Responsible for Your Child’s Injury?
When a catastrophic injury happens in a City of Alamo Heights park, the defense will try to isolate the blame. They will point to the local LLC or blame the “teenage monitor.” We don’t accept that. We go upstream.
The 5-Layer Defendant Stack
- The Operator LLC: The local entity on the lease. Often undercapitalized, they carry the primary $1M policy.
- The Franchisee: The multi-unit owner that may run several Urban Air or Altitude locations across Texas.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC. They mandate the training manuals and the safety protocols. If those protocols failed, they are liable. In the Damion Collins case, the franchisor was held responsible for 40% of the $15.6 million award.
- The Corporate Parent: Sky Zone, Inc. (formerly CircusTrix LLC), backed by Palladium Equity Partners, or Unleashed Brands, acquired by Seidler Equity Partners in 2023. These are massive private equity towers with sales exceeding $600M annually. They have the deep pockets, and we are not intimidated by their legal teams.
- The Manufacturer: If a mat tore, a spring failed, or a weld snapped, the manufacturer of the commercial court or the backyard unit (Jumpking, Skywalker, ACON) faces strict product liability.
We have litigated against Walmart, Amazon, and the global giants of the oil industry. The corporate layers behind a trampoline park are just another puzzle for us to solve. We trace the money and the control until we find the entity that made the decision that caused the injury.
Dismantling the Waiver: Why the “iPad Defense” Fails in Texas
The most common concern we hear from City of Alamo Heights parents is: “But I signed the waiver at the kiosk.” In Texas, that piece of paper is not an automatic shield. Our associate attorney, Lupe Peña, knows this better than anyone because he used to defend these waivers. There are three primary ways we defeat the trampoline park waiver:
1. The Minor-Waiver Rule (Munoz v. II Jaz Inc.)
Texas law is clear: a parent generally cannot waive a minor child’s personal injury cause of action in advance. While the parent’s own right to recover medical bills might be barred, the child’s own claim for pain, suffering, impairment, and future medical needs survives. Munoz is binding precedent in Texas, and it is the first weapon we use at Attorney911.
2. The Gross Negligence Carve-Out
Under the Texas Supreme Court’s ruling in Moriel, a waiver cannot release a defendant from gross negligence—conscious indifference to an extreme degree of risk. A park that fails to inspect a foam pit for weeks, or that knowingly operates at half the required monitor ratio, is acting with gross negligence. The $11.485 million verdict in the Cosmic Jump case was built on this exact principle. The jury saw the torn mat and the park’s knowledge of the defect and ignored the waiver entirely.
3. The Bilingual-Formation Defense (Delfingen)
For our Spanish-speaking families in the City of Alamo Heights and the greater San Antonio area, the doctrine of Delfingen US-Texas, L.P. v. Valenzuela is vital. If the park presented you with an English-only waiver on an iPad at a crowded counter, and you weren’t given a meaningful opportunity to understand the legal rights you were giving away, that waiver may be void.

Catastrophic Injuries: The Medical Realities for Children
Trampoline injuries are orthopedically and neurologically distinct. Because children’s bones are not yet fully ossified, they fail in patterns that adult skeletal systems do not.
Salter-Harris Growth Plate Fractures
The growth plate is the most vulnerable part of a child’s bone. Impact at a park or a backyard fall can result in a Salter-Harris fracture. This isn’t just a “broken bone.” If the growth plate is destroyed at age seven or nine, the bone may stop growing or grow crooked. The damages in these cases aren’t just the ER bill; they are the next ten years of orthopedic monitoring, potential corrective surgeries, and permanent limb-length discrepancy.
SCIWORA: The Invisible Spine Injury
Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) is a pediatric phenomenon. A child might land head-first in a foam pit at a park near City of Alamo Heights and have a “normal” X-ray, but the ligamentous laxity in their spine allows for a cord injury that doesn’t show up on initial CT scans. By the time the symptoms manifest six hours later, the window for intervention is closing. We work with pediatric neurologists who understand this physiology and can document the truth for a jury.
The Rhabdomyolysis Connection
As we see in our active $10 million lawsuit against the University of Houston, extended physical exertion without hydration can lead to rhabdomyolysis—muscle breakdown that produces acute kidney failure. If your child had “cola-colored” urine or listlessness 24 hours after a long jump session on a hot Texas afternoon, this is a medical emergency. Our firm has built the expert medical protocols to document and litigate these rhabdo cases, bridging the gap between sports physiology and legal accountability.
The Evidence Clock: Why the Next 7 Days Are Critical
Evidence at a trampoline park is engineered to disappear.
- Surveillance DVRs typical overwrite every 7 to 30 days.
- Incident reports are often “revised” on digital systems within 48 hours.
- Waiver kiosk databases can purge specific version metadata on a 72-hour cycle.
Every minute the park delays a 911 call or a response to your inquiry is a minute their footage gets closer to being gone forever. When you retain the Manginello Law Firm, our spoliation letter goes out within 24 hours. We demand the DVR hard drive, the attendant time-clock records, and the maintenance logs. We identify who was on duty and whether they received anything more than the industry-standard “two hours of video training.”
As client Angel Walle said: “They solved in a couple of months what others did nothing about in two years.” Speed is our baseline.
Frequently Asked Questions for City of Alamo Heights Families
Can I sue if I signed the iPad waiver?
Yes. In Texas, parents cannot waive the personal injury claims of their minor children. Furthermore, no waiver can protect a park from gross negligence. If the park violated ASTM F2970 standards, the waiver is often legally irrelevant.
How much is my child’s case worth?
Catastrophic trampoline cases are high-value because the damages span decades. A pediatric spinal injury can anchor in the $5M to $25M range for lifetime life-care planning. Complicated growth plate fractures often resolve in the $500K to $2M range. We work with life-care planners to calculate every dollar your child will need for the next seventy years.
The park’s insurance company offered to pay our medical bills. Should I take it?
No. This is likely “Med-Pay,” a small payment (often $3,000–$5,000) that usually accompanies a full release of all future claims. Depositing that check could end your multi-million dollar case before it begins. Never talk to an insurance adjuster without us.
What if my child was double-bounced by another child? Is the park still liable?
Absolutely. The park has a non-delegable duty to supervise and enforce safety rules. They cannot outsource their safety responsibility to a seven-year-old on the mat. If the monitor failed to intervene, the park is responsible.
How long do I have to do something?
The Texas statute of limitations is two years, but for minors, it is tolled until they turn 18. However, the evidence will be gone in 30 days. If you wait more than a month to hire a lawyer, you are handicapping your child’s recovery.

What Happened at the Park Wasn’t an Accident. It Was a Systemic Failure.
From the 1999 AAP warnings to the 2024 Teague epidemiology in the journal Pediatrics, the data is clear: trampoline parks are high-risk facilities that frequently operate below the safety floor they wrote for themselves. They rely on the confusion of families and the perceived shield of the waiver. They count on you not calling 1-888-ATTY-911.
Don’t let them close the file on your child’s future. The clock on the surveillance video is ticking. The adjuster is already drafting a low-ball offer. Our team is ready to send the spoliation letter and begin the corporate archeology to find the deep pockets upstream.
