“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.”
When Kaitlin Hill told ABC News about her three-year-old son Colton’s broken femur, she wasn’t speaking about a freak accident. She was describing the predictable output of a multi-billion-dollar industry that has scaled a dangerous recreational activity to industrial proportions. That scream has been echoed by thousands of families across Texas and right here in the City of Leon Valley. Colton spent months in a body cast because a heavier jumper landed on his trampoline bed—a mechanism known as a “double-bounce.”
If you are reading this in a waiting room at University Hospital or any other San Antonio-area trauma center, or if you are at home in the City of Leon Valley watching your child struggle with a heavy, uncomfortable cast, we want you to know three things immediately. First, this is not your fault. You signed the kiosk waiver because you wanted your child to have fun, and the park told you it was safe. Second, the piece of paper you signed is not the absolute shield the park wants you to believe it is. Texas law, including the landmark Munoz v. II Jaz decision, provides several pathways to hold these facilities accountable. Third, the evidence of what happened to your child is disappearing right now. Surveillance DVRs in commercial parks often overwrite in as little as seven to thirty days.

For more than 25 years, Ralph Manginello has fought corporate giants, from BP after the Texas City refinery explosion to multinational retailers like Walmart and Amazon. We aren’t just personal injury lawyers; we are a firm built to dismantle the complex corporate layers used by the parent companies behind Sky Zone, Urban Air, and Altitude.
Our team includes Lupe Peña, an associate attorney who used to sit on the other side of the table.

Whether your child was hurt at a trampoline park on Bandera Road or a backyard trampoline in a local neighborhood, we bring 25 years of courtroom experience and a memorandum of Law that covers every state in the union to your kitchen table.
Call us at 1-888-ATTY-911. We answer 24/7. Hablamos Español. We represent families, and we treat our clients like our own. As our client Chad Harris said, “You are NOT just some client… You are FAMILY to them.”
The “Accident” That Wasn’t: Systemic Negligence in the City of Leon Valley
A trampoline injury in the City of Leon Valley is a business decision that went wrong. The American Academy of Pediatrics (AAP) has formally advised against recreational trampoline use since 1999. Manufacturers, franchisors, and park operators in the City of Leon Valley have had over a quarter-century of medical consensus telling them their products maim children. They sold the tickets anyway.
Commercial trampoline parks in the City of Leon Valley operate under a set of rules called ASTM F2970. The most important thing to understand about ASTM F2970 is that the trampoline park industry wrote it themselves. They admitted exactly what is required to keep a child safe: specific attendant-to-jumper ratios, age-segregated jumping zones, and meticulously maintained foam pits.
When a park in the City of Leon Valley ignores these rules to save on payroll, it isn’t an accident—it’s a knowing violation of their own industry’s safety floor. When your child lands on a hard surface because a mat was worn or a foam pit was compacted, that isn’t bad luck. It is the result of a management team choosing margin over a child’s life.
In Harris County, a jury returned an $11.485 million verdict against Cosmic Jump because they had actual knowledge of a torn trampoline slide and did nothing. A 16-year-old fell through a hole onto concrete. The waiver was signed. The jury found gross negligence anyway. That is the kind of case we are built for. Whether it’s a City of Leon Valley park operating at half-staff on a busy Saturday or a manufacturer selling a backyard trampoline that they know fails UV-degradation tests, we hold them accountable.
Why Your Case Is Worth More Than the Medical Bills
If your child suffered a catastrophic injury in the City of Leon Valley, the medical bills you see today are only the beginning. A “broken ankle” in an eight-year-old is often a Salter-Harris growth plate fracture. This is a disruption of the cartilaginous zone where new bone is produced. If that growth plate is destroyed at age nine, the bone may not grow straight, or it may stop growing entirely. Your child might not face the full consequences until they reach skeletal maturity at age 14 or 16—years after the trampoline park hopes you’ve settled your case for the cost of the initial surgery.
We build cases that look 70 years into a child’s future. We retain Certified Life Care Planners and pediatric orthopedic surgeons to project every medically necessary cost: multiple follow-up surgeries, lifetime monitoring, corrective osteotomies, or specialized educational accommodations. If your child sustained a traumatic brain injury (TBI) from a head strike on an unpadded frame in a City of Leon Valley park, the damages aren’t just the ER visit. It is the executive function damage, the academic regression, and the lifetime earning capacity loss that follows a developing brain injury.
National industry data shows that catastrophic pediatric spinal cord injuries (SCI) can have lifetime care costs exceeding $15 million. Even moderate cases involving growth plate damage or comminuted femoral shaft fractures routinely anchor in the $500,000 to $2.5 million range.
We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure—the exact same pathology seen in teenagers who jump for hours in a hot City of Leon Valley park without hydration. We know how to prove these medical conditions because we are doing it right now.
Dismantling the City of Leon Valley Kiosk Waiver
The park’s insurance adjuster will call you within 48 hours. They will be “friendly.” They will ask how your child is doing. Then, they will mention the waiver you signed at the kiosk as if it ends the conversation.
Do not believe them. In the City of Leon Valley, and throughout Texas, the waiver has three massive weaknesses that our former-insurance-defense team exploits:
- The Gross Negligence Carve-Out: No waiver in Texas can release a company from gross negligence. If the park in the City of Leon Valley knew a court monitor was on their phone, or knew a foam pit was bottoming out, and did nothing, the waiver is void.
- The Munoz Rule: Under Munoz v. II Jaz, a parent generally cannot sign away a minor child’s right to sue for personal injuries. Your child’s own claim survives your signature.
- The Dresser Fair Notice Doctrine: A Texas waiver must be conspicuous. If the release language was buried in 20 screens of text on a tablet at a busy City of Leon Valley park entrance, it may fail the fair notice test.
If your family’s primary language is Spanish, and the City of Leon Valley park gave you an English-only waiver without explanation, the Delfingen doctrine allows us to challenge the very formation of that contract. Lupe Peña speaks with our Spanish-speaking clients directly to ensure their rights are never ignored because of a language gap.
Strategic Discovery: How We Beat the “Don’t Call 911” Culture
Public reviews and Tripadvisor parents have reported a disturbing pattern: managers at parks like Urban Air and Sky Zone instructing employees NOT to call 911. They want to minimize the incident while your child is in pain. Every minute they delay is a minute the surveillance video gets closer to being overwritten.
Our spoliation letter is already drafted. It goes out by certified mail to the City of Leon Valley park, its franchisor, and its insurer within 24 hours of your retention. We demand more than just the video. We demand:
- Original incident reports before they are “revised” by risk management.
- Version-history metadata from the kiosk waiver database.
- Attendant shift logs and training records.
- Foam-pit refill and maintenance logs.
- Audit reports from common franchisors like Sky Zone Franchising LLC or Unleashed Brands.
We don’t just “handle” cases; we prosecute them with the same intensity Ralph Manginello used against BP. We advance every expense—the biomechanical engineer, the pediatric specialist, the ASTM expert. You pay nothing unless we win.
Frequently Asked Questions for City of Leon Valley Families
Can I sue if I signed the waiver at the City of Leon Valley trampoline park?
Yes. Waivers only cover ordinary negligence, not gross negligence or recklessness. In Texas, a parent’s signature cannot bar a minor child’s personal injury claim. We have seen juries in Harris County and across the state throw out these waivers when the park’s conduct was egregious.
My child’s injury was at a neighbor’s house in City of Leon Valley. What happens to their home insurance?
Backyard trampolines are often excluded by homeowners’ insurance unless a specific endorsement was bought. However, your child may still have a claim under the “attractive nuisance” doctrine. This holds homeowners responsible when they have a hazardous item like a trampoline that naturally draws in children who can’t appreciate the risk. We look at every layer, including the manufacturer of the trampoline (Jumpking, Skywalker, Springfree).
What if the park in City of Leon Valley says the video was “lost”?
When we hear “unavailable,” we hear “spoliation.” We retain digital forensic examiners to image the DVR. If the video glitched on four cameras simultaneously at the moment of injury—as happened in a $3.5M Georgia case—we seek an adverse inference instruction. The jury is then told to assume the video would have hurt the park’s case.
How long do I have to file a claim in City of Leon Valley?
The Texas statute of limitations is two years from the date of injury. For minors, this clock is “tolled” (paused) until they turn 18, giving them until age 20 to file. However, waiting is a disaster for evidence. Witnesses disappear and video overwrites. Call 1-888-ATTY-911 today.
Why Your Call to Attorney911 Matters Right Now
What happened to your child at a City of Leon Valley park wasn’t an accident; it was the predictable output of a business model that prioritizes throughput and margin over the biomechanical safety of children. The AAP has been warning us since 1999. The insurance companies are raising premiums by 400% because they know these parks are dangerous.
You need a firm that knows ASTM F2970 better than the park’s manager. You need an attorney who has fought Fortune 500 defense firms and won. You need a team that understands why your child has dark, cola-colored urine after a long day of jumping—and knows the medical experts who can prove it’s rhabdomyolysis.
Call Attorney911 at 1-888-ATTY-911. We represent families in the City of Leon Valley and across the country. Let us take the burden of the insurance adjusters off your shoulders so you can focus on your child’s recovery. Hablamos Español. No fee unless we win. The spoliation letter goes out tomorrow. The case starts today.
Detailed Liability Analysis: The City of Leon Valley Defendant Stack
When we file a lawsuit for a City of Leon Valley injury, we don’t just name the park. We perform a “corporate archeology” to ensure there is enough insurance to cover a lifetime of care.
Layer 1: the Operator LLC
This is the entity running the local facility on Bandera Road or near your City of Leon Valley neighborhood. They usually carry a $1 million policy. In a catastrophic injury case, that is the floor, not the ceiling.
Layer 2: The Franchisee
Many City of Leon Valley parks are owned by multi-unit groups. They may own five or ten Urban Air or Sky Zone locations. This layer adds additional insurance towers.
Layer 3: The Franchisor
Entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings license the brand. Under the theory of “apparent agency,” because the park uses the franchisor’s logos, uniforms, and waivers, the franchisor can be held liable for the operator’s negligence.
Layer 4: The Corporate Parent
This is where the massive money lives. Sky Zone, Inc. (formerly CircusTrix LLC) is owned by Palladium Equity Partners. Urban Air is owned by Unleashed Brands, which was acquired by Seidler Equity Partners in 2023. These are massive conglomerates with excess insurance layers reaching tens of millions of dollars.
Layer 5: The Manufacturers
If a spring broke, a net tore, or a carabiner failed on an Urban Air Sky Rider or an Altitude climbing wall, the manufacturer (like Ropes Courses, Inc.) is a product liability defendant. We use the CPSC recall history to prove they sold a product they knew would fail.
Pediatric Injury Mechanisms: What City of Leon Valley Doctors See
Double-Bounce Physics
When a 200-pound adult lands while a 50-pound child pushes off, the energy multiplication can be up to 4x. The child is launched at a velocity their bones simply cannot handle. This is the #1 cause of City of Leon Valley pediatric femur fractures.
Foam Pit Compaction
Foam pits look soft, but they compress. ASTM F2970 requires deep pits with specific rotation cycles. In the City of Leon Valley area, we’ve seen pits where children hit the concrete subfloor. The result is often SCIWORA (Spinal Cord Injury Without Radiographic Abnormality)—where the neck looks fine on a CT scan but the child is paralyzed hours later.
Zipline and Harness Failure
Urban Air’s Sky Rider zipline has a documented chain-wide pattern of cord strangulation and harness fall failures. If your child fell from height in a City of Leon Valley park, the harness system is a primary target for design defect litigation.
The Evidence Clock in City of Leon Valley
The Saturday afternoon your child was hurt is disappearing. By Day 10, the City of Leon Valley park’s DVR has overwritten the footage. By Day 20, the teenage attendant who witnessed the double-bounce has probably quit—the industry has a 150% turnover rate.
We don’t wait for the park to “check” their files. We retain digital forensic examiners to image the hard drives. We subpoena the cell phone records of the court monitors to prove they were distracted. We pull the historical Wayback Machine captures of the park’s website to prove they advertised “expert supervision” while hiring children with four hours of training.
A Life-Care Plan for Your City of Leon Valley Child
When a City of Leon Valley surgeon explains what happens when a growth plate is destroyed, they are giving you a medical prognosis. We turn that into a legal demand.
Our firm builds a Pediatric Life-Care Plan category-by-category:
- ** Episcopal care:** Future hardware removal and corrective surgeries.
- Monitoring: Annual orthopedic visits through age 18.
- Therapy: Multi-year PT, OT, and cognitive rehab for TBI cases.
- Vocational: The forensic economic calculation of lost earning capacity over a 60-year work life.
- Educational: Assistant technology and special school placements.
We advanced the cost of these experts in every case. Your child’s recovery fund stays intact for their actual recovery.
Why Competitive Families in City of Leon Valley Need Attorney911
City of Leon Valley has a vibrant youth sports culture. From elite cheer groups to competitive club soccer, our local kids are athletes. When a trampoline injury sidelines a student-athlete, the loss isn’t just a medical bill—it’s a scholarship pathway. It’s a Division 1 dream. It’s years of investment by the parents.
We understand these stakes because we live here. Ralph Manginello is a dual-licensed attorney who has spent decades making Fortune 500 companies take Texas families seriously.
The Language Access Barrier in City of Leon Valley
South Texas trampoline cases often involve Spanish-speaking families. The parks use this as a tactic. They slide an English iPad waiver across a counter and pressure you to “sign quickly so the kids can jump.”
Delfingen US-Texas v. Valenzuela is our weapon against this. If you couldn’t read the waiver, you didn’t form a contract. Lupe Peña represents our clients directly, ensuring the insurance adjuster’s “language barrier” tricks never work.
FAQs for City of Leon Valley Parents
Is there a “safe” way to use a trampoline park?
The AAP says no. If you go, teach your child: one person per bed, no flips, and “feet first” always. But remember, you cannot control the negligence of other jumpers or the park’s understaffing.
Should I take the $3,000 “Med-Pay” check from the insurance company?
No. That check is a Trojan Horse. The release on the back of the check typically ends your case. If your child has a growth plate injury or a TBI, $3,000 won’t cover their first month of therapy.
What if I’m undocumented?
The Texas civil courts do not report plaintiffs to ICE. Your immigration status does not affect your child’s right to receive compensation for their injuries. Our firm is a safe place to discuss your case with 100% confidentiality.
The City of Leon Valley park manager said it was a “freak accident.” Should I believe him?
“Freak accident” is code for “we don’t want to admit we were understaffed.” Most City of Leon Valley trampoline injuries are the result of known physics and direct violations of ASTM F2970 safety standards.

Technical Appendix: Safety Standards in the City of Leon Valley
ASTM F2970-22
This is the commercial standard. It governs the City of Leon Valley parks. It requires specific attendant training—not just “shadowing” another staff member, but a certified curriculum. It mandates daily pre-opening inspections. When we depose the City of Leon Valley park manager, we ask for their ASTM compliance certificates. If they don’t have them, the case for gross negligence is open.
EN ISO 23659:2022
The US is one of the only developed nations without a binding national safety standard. In Europe, EN ISO 23659:2022 is the mandatory law. We use this international benchmark to show City of Leon Valley juries that the “industry standard” in the US is the floor, not the ceiling.
ASTM F381
This governs backyard trampolines in the City of Leon Valley. It prohibits users under age six. If you bought a Jumpking or Skywalker trampoline with a “Toddler Time” marketing sticker, the manufacturer has violated their own safety standard. We hold them accountable.
Texas Deep-Block Citations for City of Leon Valley Litigation
When we file your case in Bexar County or a surrounding district, we rely on the 36-item Texas Litigation Playbook:
- TX-1 Dresser Industries: The fair-notice doctrine. The City of Leon Valley park must be express and conspicuous.
- TX-4 Munoz v. II Jaz: The minor child waiver-void rule.
- TX-6 Gross Negligence Split: We plead gross negligence in every case to reach the punitive damages cap under CPRC § 41.008.
- TX-21 Corbin v. Safeway Stores: The invitee 4-element test for City of Leon Valley premises liability.
- TX-26 Class B Inflatables: We pull the TDI inspection records for Urban Air’s Sky Rider and bungee tramps using the Texas Public Information Act.
- TX-30 Delfingen: The bilingual-formation attack.
The Rhabdomyolysis Bridge: A Warning for City of Leon Valley Families
Twelve to forty-eight hours after a long afternoon at a City of Leon Valley park, watch for tea-colored or “cola” urine. Watch for muscle pain so severe your child can’t stand up. Watch for vomiting.
This is exertional rhabdomyolysis. It is a medical emergency that leads to acute kidney failure. Our firm’s $10 million UH hazing case uses the same medical experts required for trampoline rhabdo litigation. The park never warned you about this. We will.
Why The Pressure in City of Leon Valley Matters
The San Antonio metro area, including the City of Leon Valley, is a saturated market. Sky Zone, Urban Air, and Altitude all compete for the same families. This competition creates price pressure. Price pressure leads to payroll cuts. Payroll cuts lead to under-monitored courts.
Your daughter wasn’t hurt by bad luck. She was hurt by a corporate decision to skip a shift monitor during a summer AC-seeking peak. We name that decision. We name that decision-maker. We win that case.
Final Closing Sequence: The Inevitability of Accountability
What happened to your child at a City of Leon Valley park wasn’t an accident—it was the predictable output of a corporate system. The AAP has warned against it since 1999. ASTM F2970 was written by the industry as a safety floor, which the park chose to jump below. The waiver was drafted by lawyers who count on you not knowing state law.
Attorney911 was built for this. Ralph Manginello brings 25+ years of federal court experience. Lupe Peña knows the insurance defense playbook because he used to write it. We advanced every expert expense—the biomechanist who reconstructs the 4x launch force, the pediatric surgeon who forecasts the growth plate damage, and the life-care planner who quantifies the future.
The evidence is evaporating. The DVR overwrites in days. The waiver kiosk purges in 72 hours. In Texas, the parent’s derivative claim for medical bills runs out in two years. We file fast. We investigate aggressively.
