The first thing you hear isn’t the impact. It isn’t the sound of the springs or the rustle of the foam cubes. It is the scream. As Kaitlin “Kati” Hill told ABC News after her three-year-old son Colton was injured during a “Toddler Time” session at a park, it was “the worst scream that you could ever have heard from a child.” Colton’s feet hit the mat, his knees buckled, and his femur—the strongest bone in the human body—snapped in an instant.

If you are reading this in a waiting room at McLane Children’s Medical Center in Temple or at a trauma bay in Waco, you are likely feeling two things: terror and guilt. You think about the kiosk at the Urban Air on West Waco Drive where you signed that digital document. You think about the “Toddler Time” advertisement that promised a safe environment for small children. You feel like you failed to protect your child.

We are here to tell you that this was not your fault. What happened to your child wasn’t a freak accident. It was the predictable output of a business model that prioritizes throughput over safety. At Attorney911, led by Ralph Manginello with over 25 years of experience in catastrophic injury law, we see these cases for what they are: systemic failures. Whether the injury happened at the local Waco Urban Air, the massive Xtreme Jump flagship in Temple, or on a backyard Jumpking or Skywalker trampoline in a neighborhood off Highway 6, the legal path to accountability is the same.

The park’s insurance adjuster will call you soon. She will be friendly. She might offer to pay your ER copay in exchange for a signature on a “simple release.” Do not sign it. That waiver you signed at the kiosk is not the absolute shield the park wants you to believe it is. In Texas, a parent cannot sign away a minor child’s right to sue for their own injuries. We know the case law. We know the industry. And we know that while the park’s surveillance DVR is set to overwrite in as little as 7 to 30 days, our spoliation letter goes out within 24 hours of your call.

The Reality of Trampoline Injuries in Waco and Beyond

Waco families deserve the facts that the industry tries to hide behind bright lights and loud music. Trampoline park injuries are not a minor risk; they are a documentable public health crisis. According to a landmark 2024 study published in the journal Pediatrics by Teague et al., researchers tracked over 13,000 injuries across 8.4 million jumper-hours. The data revealed that foam pits produce 1.91 injuries per 1,000 hours, while high-performance “advanced skill” jumping produces 2.11 per 1,000 hours.

In a metro like Waco, where families flock to centers like Urban Air or drive down I-35 to the 60,000-square-foot Xtreme Jump facility in Temple, thousands of children are airborne every weekend. Nationally, the Consumer Product Safety Commission (CPSC) tracks approximately 300,000 trampoline-related emergency room visits every year. A staggering 1.6% of all pediatric emergency department trauma visits are now trampoline-related, according to the American Journal of Roentgenology (AJR 2024).

These are not just sprained ankles. We represent families dealing with:

  • Commuted femoral shaft fractures requiring surgery and intramedullary steel nails.
  • Salter-Harris growth plate injuries that can cause a child’s leg to grow crooked or stop growing entirely as they reach their teenage years.
  • Traumatic Brain Injuries (TBI) from falls through torn mats onto concrete.
  • Cervical spinal cord injuries leading to permanent paralysis.

Ralph Manginello has spent his career making corporate giants accountable, from the BP Texas City refinery explosion litigation to complex multi-million dollar traumatic brain injury settlements. We bring that same level of Fortune 500 litigation experience to every Waco trampoline case.

Why the “Waco Waiver” Doesn’t End Your Case

If you signed an iPad waiver at a park in Waco or Temple, you probably saw language claiming the park isn’t responsible for anything, including death or paralysis. The park’s insurance company counts on you believing that piece of paper. They are wrong.

In Texas, the law regarding waivers is specific and often favors the family of an injured child. First, under the landmark case Munoz v. II Jaz, Inc., a parent generally cannot waive a minor child’s personal cause of action for injuries. While you may have signed a document, your child didn’t, and Texas courts have held that a parent lacks the authority to strip a child of their legal rights before an injury occurs.

Second, we attack the “Fair Notice” doctrine. Under Dresser Industries, Inc. v. Page Petroleum, Inc., any release of future negligence in Texas must be “conspicuous.” It must be in a larger font, a contrasting color, or otherwise attract the attention of a reasonable person. If that waiver was buried in a 20-screen click-through at a crowded kiosk on West Waco Drive while your kids were tugging at your arm, it may be legally unenforceable.

Finally, no waiver in Texas covers gross negligence. If the park knew a trampoline mat was torn—like the slide at Cosmic Jump in Houston that led to an $11.485 million verdict—and they let your child jump on it anyway, the waiver is a legal nullity.

Our team includes associate attorney Lupe Peña, who previously worked for the insurance companies defending these exact types of businesses. He knows their playbook. He knows where the holes are in their waivers. Most importantly, he speaks Spanish fluently, ensuring that Waco’s Spanish-speaking families have a direct line to a senior attorney who understands both the law and their culture.

The Mechanisms of Injury: Why Trampolines Are Physics Traps

The industry markets these facilities as “safe family fun,” but the physics of an interconnected trampoline court tells a different story. The most common catastrophic injuries we see in Central Texas involve three specific mechanisms that ASTM F2970, the industry’s own safety standard, was supposed to prevent.

1. The Double-Bounce (Energy Transfer)

This is the “catapult” effect. When a 200-pound adult lands on a trampoline bed at the same moment a 60-pound child is pushing off, the energy from the adult is transferred to the child. The child is launched into the air with up to 4x their normal launch force. Their developing skeleton is not built to decelerate from that height. This is how we see shattered tibias and compound femur fractures at parks that fail to enforce age and weight separation.

2. Foam Pit Submerge-Entrapment and “Bottoming Out”

Foam pits look soft, but they are often the most dangerous attraction in the building. As documented in the case of Ty Thomasson at a park in Phoenix, a foam pit that is too shallow or has compressed cubes can cause a jumper to hit the hard floor beneath. Even more terrifying is the pediatric risk of “submerged entrapment,” where foam blocks close over a small child, leading to asphyxiation because there wasn’t a dedicated monitor watching that specific pit.

3. Harness and Belt Failures on Climbing Walls

Many Waco families visit Urban Air specifically for the climbing walls and “Sky Rider” coasters. In Sugar Land, the Lakhani family’s daughter fell 30 feet because an attendant reportedly failed to attach her safety line. Modern adventure parks are bolting on mechanical attractions—go-karts, ziplines, and ropes courses—that require rigorous, professional staffing. When a park hires a 16-year-old with three hours of training to manage a life-safety harness, the results are often fatal.

Building the Case: The Attorney911 Forensic Protocol

We do not just “handle” personal injury cases. We build forensic architectures. Most generalist firms will send a basic demand letter. We deploy a 10-step case-build that starts the moment you retain us:

  1. Immediate Spoliation Demand: We certified-mail a “litigation hold” to the park and their corporate parent (such as Unleashed Brands or Sky Zone, Inc.). We demand they stop the DVR overwrite cycle and preserve the specific mat, spring, or harness that failed.
  2. Corporate Structure Archaeology: Local parks in Waco are often shielded by a “5-Layer Stack.” There is the local LLC, the franchisee, the franchisor (like UATP Management), the parent conglomerate (like Seidler Equity Partners), and the private equity sponsor. We go upstream because that is where the real insurance money lives.
  3. Digital Forensic Acquisition: If the park claims the video “glitched” or is “missing”—a tactic we saw in the Mathew Knight case in Georgia where four cameras miraculously failed at once—we retain digital examiners to interrogate their hard drives.
  4. ASTM Compliance Audit: We compare the park’s operations manual and time-clock records against ASTM F2970. We often find that one monitor was watching 60 jumpers when the industry standard requires a much stricter ratio.
  5. Biomechanical Reconstruction: We work with engineers who model the G-forces involved in your child’s injury. This proves the “double-bounce” wasn’t an inherent risk but a predictable result of poor supervision.
  6. Medical Chronology and Specialist Network: We deal with the medicine of the injury. Whether it is rhabdomyolysis—a muscle-breakdown condition we are actively litigating in a $10 million lawsuit against the University of Houston—or a Salter-Harris growth plate fracture, we have the experts who can explain the 40-year cost of care to a jury.

Rhabdomyolysis: The Under-Recognized Emergency for Waco Campers

If your child spent a long day at a summer camp or a birthday party jumping for two or more hours in a hot, poorly ventilated facility, you must watch for more than just broken bones. Exertional rhabdomyolysis (“rhabdo”) occurs when overexertion and dehydration cause muscle tissue to rupture, leaking the protein myoglobin into the blood.

Watch for:

  • Dark, tea-colored or “cola-colored” urine.
  • Extreme muscle pain and swelling in the legs.
  • Vomiting and confusion.

This is a life-threatening emergency that leads to acute kidney failure. At Attorney911, we have a unique bridge to this medicine. We are currently litigating a $10 million case involving rhabdo and kidney failure; we know the CK (creatine kinase) levels, we know the nephrology experts, and we know how to prove that the park’s failure to provide mandatory water breaks and heat monitoring caused your child’s organ damage.

Liable Parties: Who Really Pays for a Trampoline Injury?

When a catastrophic injury occurs at a place like the Urban Air on W. Waco Dr, the insurance adjuster will try the “Policy Limit Shell Game.” They will tell you the operator only has a $1 million policy.

We don’t accept that. Our investigation identifies every layer:

  • The Operator’s Primary GL: The starting point.
  • The Franchisee’s Umbrella: Often reaching $5 million to $10 million.
  • The Franchisor’s Additional-Insured Layer: National chains like Sky Zone or Urban Air require their local owners to name the “big” corporate office as an additional insured.
  • The Parent Company’s Excess Tower: Deep pockets held by private equity firms like Seidler Equity Partners or Palladium Equity.
  • The Manufacturer: If a mat tore or a weld on a Jumpking or Skywalker trampoline failed, we bring a strict product liability claim against the manufacturer and the retailer (like Walmart or Amazon).

We have sued some of the largest corporations in the world, including BP, Amazon, Walmart, and FedEx. The corporate legal teams behind national trampoline chains do not intimidate us. We have already beaten their playbook.

Why Your McLennan County Jury Matters

Waco is a unique legal market. It is a city of families, of faith, and of Baylor pride. But it is also a place where people believe in personal responsibility. The trampoline park will try to use that against you. They will argue that you “knew it was risky” and that your child “should have been more careful.”

We flip that script. Personal responsibility starts with the business that takes your money. If a park in Waco markets itself as a safe venue for a 5-year-old’s birthday party, they are responsible for following the rules their own industry wrote. When a jury in Harris County saw Max Menchaca’s TBI, they didn’t blame the kid; they hit the park with $6 million in punitive damages. We know how to speak to McLennan County jurors about the sacred duty of a business to protect the children in its care.

FAQs for Waco Parents at 2 AM

1. I signed the waiver at Urban Air. Does that mean I can’t sue?

No. In Texas, a parent cannot waive a minor child’s independent legal claim. Additionally, waivers do not cover gross negligence or reckless behavior. If the park failed to staff enough monitors or had broken equipment, the waiver likely will not stop your case.

2. The park manager offered a refund and to pay our deductible. Should we take it?

Do not sign anything to receive that money. This is often a “Med-Pay” trap. They give you a small check now in exchange for a release that prevents you from seeking millions in future medical care later. Call us before you accept any “goodwill” payment.

3. How long do I have to do something about a trampoline injury in Texas?

The statute of limitations for personal injury is generally two years. For a minor, that clock is “tolled” (paused) until they turn 18, meaning they have until age 20. HOWEVER, the evidence clock is much shorter. If you don’t act within the first 30 days, the surveillance video of the accident will be gone forever.

4. What is a “Salter-Harris” fracture?

This is a fracture that involves the growth plate of a child’s bone. It is a common trampoline injury. It is critical because if the plate is damaged, the limb may not grow straight or at the same length as the other. These cases require life-care planners to project the cost of orthopedic surgeries 10 or 15 years into the future.

5. Does it matter that my primary language is Spanish?

Yes. Under the Delfingen doctrine in Texas, if the park provided an English-only waiver and you are a primary Spanish-speaker who was pressured to sign quickly, we can argue the waiver was never validly formed. Lupe Peña of our office handles these bilingual investigations personally.

The Evidence Clock is Ticking

Right now, in a server room at a trampoline park, your evidence is being buried. The DVR is preparing to overwrite the moment of impact. The attendant who saw your child fall is being transferred to a different shift. The “incident report” is being reviewed by a corporate risk manager who is “refining” the details.

The Moat of Protection: Our Forensic Expertise

Most personal injury firms can’t tell you what ASTM F2970 requires of a trampoline park. We can cite it from memory—the attendant-to-jumper ratios, the required foam pit depth, the age-separated jumping zones. When we depose the park’s operations manager, we know their standards better than they do. We have gone head-to-head with Fortune 500 corporations and made them pay. The parent conglomerates behind Sky Zone (owned by Palladium Equity) and Urban Air (owned by Seidler Equity) do not frighten us. We have already won the fight against bigger giants like BP.

Your child’s life changed in one bounce. The park knew the risks. They knew the AAP has recommended against these facilities for 25 years. They took your money and ignored the rules. We are here to make them pay.
