“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 “Kati” Hill, a mother whose three-year-old son Colton suffered a broken femur at a trampoline park during a “Toddler Time” session. Her warning post was shared 240,000 times on Facebook because it resonates with a terror every parent in the Town of Prosper knows. You walk into a facility like the Urban Air in McKinney or the Sky Zone in Frisco, you sign a digital waiver on a kiosk while your children tug at your sleeve, and you believe the “safety” marketing. Then, in two seconds, a double-bounce or a harness failure changes your child’s life forever.
At Attorney911, we have spent more than 25 years standing at the bedsides of families in the Town of Prosper and throughout Texas who are facing the aftermath of a business decision disguised as an accident. Our founder, Ralph Manginello, has litigated against Fortune 500 giants like BP, Walmart, and Amazon. We bring that same “no-fear” infrastructure to the trampoline industry—an industry that is no longer about trampolines, but about multi-million-dollar family entertainment centers (FECs) backed by private equity and shielded by layers of legal paperwork.
If your family is currently dealing with a catastrophic injury at a trampoline park near the Town of Prosper, the most important thing we can tell you is this: the waiver you signed is not a wall. It is noise designed to make you go away. We have built our practice around the specialized medicine and complex corporate archeology required to pierce those shields. Whether it is a Salter-Harris growth plate fracture, a traumatic brain injury (TBI) from a concrete-strike at a park like Cosmic Jump, or the agonizing realization of rhabdomyolysis after a hot Saturday afternoon of jumping, we know how to hold these billion-dollar conglomerates accountable.
Call us 24/7 at 1-888-ATTY-911. Hablamos Español. Our associate attorney Lupe Peña used to defend these very companies; now she uses that exact playbook to win for our clients. We work on a contingency basis—no fee unless we win—and our spoliation letter goes out within 24 hours of your call to preserve the surveillance video before the Town of Prosper park overwrites it.
The Reality of Trampoline Parks in the North Texas Corridor
The Town of Prosper sits at the epicenter of a massive “adventure park” boom. Within a few miles of Prosper ISD schools and master-planned neighborhoods like Windsong Ranch, parents have their pick of national chains including Urban Air, Sky Zone, Altitude, and DEFY. These facilities are high-throughput environments designed to maximize “jumper-hours.”
According to the American Academy of Pediatrics (AAP) in their landmark 2024 studies in the journal Pediatrics, trampoline park injury rates are not just rising; they are producing more severe outcomes than backyard equipment. Nationally, more than 300,000 trampoline-related ER visits happen every year. In a high-density family market like the Town of Prosper, that share is measured in the thousands.
Why Your Injury in the Town of Prosper Wasn’t an Accident
A trampoline stores and releases elastic potential energy. It is essentially a catapult. When a 200-pound adult lands on a bed while a 60-pound child from the Town of Prosper is pushing off, the energy transfer multiplies the child’s launch force by up to 4x. This is the Double-Bounce Mechanism, and it is the signature injury of the trampoline park industry.
ASTM F2970 is the safety standard that the trampoline industry wrote about itself. It requires parks to operationalize age and weight separation to prevent exactly this kind of energy transfer. When a park in the Town of Prosper area violates that standard—when a court monitor is on his phone instead of stopping an adult from jumping near a toddler—the injury that follows is a business decision. The park chose margin over safety.
The Corporate Structure: Who Are You Actually Suing?
When a child is hurt at the Urban Air McKinney or the Altitude in Richardson, the local manager may be sympathetic, but the legal reality is a layered fortress. “Sky Zone” or “Urban Air” isn’t one company; it is a five-layer stack designed to keep the money upstream.
- The Operator LLC: This is the single-location entity that runs the park near the Town of Prosper. It often carries a minimum $1 million policy—not nearly enough for a spinal cord injury.
- The Franchisee: A multi-unit owner who may own parks across Dallas and Collin County.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC (Urban Air). They set the safety rules but try to disclaim responsibility when they aren’t followed.
- The Parent Company: Sky Zone, Inc. (formerly CircusTrix LLC) or Unleashed Brands. Effective January 1, 2023, Sky Zone, DEFY, and Rockin’ Jump are all sister brands under one roof.
- The Private Equity Sponsor: Firms like Palladium Equity Partners or Seidler Equity Partners. They are the deep pockets who approve the budget cuts that lead to understaffed courts in the Town of Prosper.
We know how to trace the money. Ralph Manginello’s experience in the BP Texas City refinery litigation taught our firm how to manage complex, multi-defendant cases against multinational corporations. We don’t just sue the local LLC; we go upstream. We use the Collins v. Urban Air $15.6 million arbitration award as a roadmap—a case where the franchisor (UATP Management) was held responsible for 40% of the damages because of a “systemic failure” to implement safety changes.
The Texas Waiver: Why Munoz and Dresser Protect Your Family
The park’s insurance adjuster will call you at your home in the Town of Prosper within 48 hours. She will be “friendly.” She will mention the waiver you signed and tell you the park is “so sorry, but you accepted the risk.”
She is wrong.
Texas law has some of the strongest protections for families of injured children if you have an attorney who knows where to look. We run every Town of Prosper waiver through a specialized attack playbook based on three Texas pillars:
- The Munoz v. II Jaz Doctrine: In Texas, a parent generally cannot sign away a minor child’s right to sue for personal injuries. Your signature at the kiosk may bar your claim, but it does not bar your child’s claim.
- The Dresser Fair Notice Requirement: Under the “Express Negligence Doctrine,” a waiver in Texas must specifically use the word “negligence” and must be “conspicuous.” A release buried in a 20-screen iPad click-through often fails this test.
- The Moriel Gross Negligence Carve-Out: In the Town of Prosper, and across Texas, no waiver can release a company from gross negligence. If a park knew about a torn mat or a shallow foam pit and let your child jump anyway, that is conscious indifference. That is what happened in the $11.485 million Cosmic Jump verdict in Houston—the jury found gross negligence despite a signed waiver.
Catastrophic Injuries We Handle in the Town of Prosper
A trampoline injury to a developing body is a lifelong event. We work with board-certified pediatric orthopedic surgeons and neurologists to document the full scope of damages.
Salter-Harris Growth Plate Fractures
In a Town of Prosper child, the growth plates (physes) are made of cartilage. They are much weaker than the bone itself. A “broken leg” at age seven is frequently a Salter-Harris fracture. If not treated with specialized surgery, that bone may not grow straight or may stop growing entirely. We ensure your Pediatric Life-Care Plan accounts for the corrective osteotomies your child will need at ages 12, 14, and 18.
SCIWORA (Pediatric Spinal Cord Injury)
Children in the Town of Prosper have a flexible cervical spine. They can sustain a “Spinal Cord Injury Without Radiographic Abnormality.” This means a CT scan in a local ER might look “normal,” but the cord has suffered an intimal tear or ischemia. The Elle Yona TikTok case (27M+ views) showed the world how a backflip into a foam pit can cause a vertebral artery dissection and a spinal cord stroke. If a park monitor in the Town of Prosper didn’t stop that flip, they are liable for the result.
Rhabdomyolysis and Acute Kidney Failure
If your child has “cola-colored” urine or muscles that feel rock-hard 24 hours after a long Town of Prosper birthday party, this is a medical emergency. Extended jumping in the 85-degree heat of an indoor park without hydration can cause muscle breakdown (rhabdo) that shuts down the kidneys. We are currently litigating a $10 million lawsuit against the University of Houston involving this exact pathology. We know the creatine kinase (CK) levels, we know the renal experts, and we know how to prove the park’s environment caused the crash.
48-Hour Evidence Preservation: The “DVR Clock”
The trampoline park industry relies on evidence disappearing. DVR systems at Town of Prosper area parks typically overwrite every 7 to 30 days. Incident reports are often “revised” at the corporate office within 48 hours of the injury to remove mentions of staff error.
When you retain Attorney911, we send a formal Spoliation Letter via certified mail to the operator, the franchisor, and the insurance carrier within 24 hours. We demand:
- Multi-angle surveillance footage (before it overwrites).
- The original, handwritten incident report (before it’s sanitized).
- The waiver kiosk metadata (to prove the signature was rushed or inconspicuous).
- Attendant training logs and shift schedules.
We don’t wait for the park to “check their cameras.” We force them to preserve the hard drives.
Frequently Asked Questions for Prosper Families
Can I sue if the park’s attendant was just a teenager?
Yes. The fact that the person watching your child was a 17-year-old making minimum wage is actually part of our case. ASTM F2970 requires specific training and monitor-to-jumper ratios. Assigning an untrained minor to supervise a high-risk court is Negligent Hiring and Training.
How much is my child’s case worth in the Town of Prosper?
Damages depend on the injury, but we look beyond the hospital bill. We calculate the 60-year horizon: future medical care, lost earning capacity, educational accommodations (IEP needs), and the loss of “hedonic” value—the ability to play sports or live a pain-free life. A serious growth plate injury can anchor in the $500,000 to $2M range, while permanent spinal injuries can reach $10M to $25M+.
What if my ex-spouse signed the waiver?
Texas Family Code § 153.073 is very specific about signer authority. If a grandmother, an aunt, or a family friend at a birthday party signed for your child, they generally lack the legal authority to bind your child to a waiver. This is a common and powerful attack vector we use in Town of Prosper cases.
Should I take the $5,000 “Med-Pay” offer from the park?
No. This is the “Med-Pay Trojan Horse.” The insurance adjuster offers a small check for your immediate co-pays. Often, the fine print on the back of that check or the cover letter releases the park from ALL future liability. Never deposit an insurance check from a park until we have reviewed it.
