“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, the mother of three-year-old Colton, telling ABC News what happened the day a trampoline park broke her son’s femur. Her warning has been shared a quarter of a million times because it resonates with the most profound fear of every parent in Anna. We have represented families who stood at the same trauma-bay bedsides at Children’s Medical Center Plano and Children’s Medical Center Dallas, watching surgeons explain what happens when a growth plate is destroyed at age nine.
If your family is living through that nightmare right now, what you do in the next 7 days determines whether your child receives the compensation they need for a recovery that may take decades. While you are focused on the surgical schedule, the trampoline park’s risk management team is focused on their DVR overwrite cycle.
In Anna, we are seeing a massive surge in trampoline park attendance and backyard trampoline density. Families are driving down US-75 to the Urban Air in McKinney or the Sky Zone in Frisco. In neighborhoods across Anna, from Anna Town Square to Hurricane Creek, the sound of rhythmic bouncing is the background track of every Saturday afternoon. But behind the marketing of “safe family fun” is a systemic architecture designed to prioritize profit over pediatric safety.
We represent children. We represent families. And we represent the fact that a trampoline injury in Anna is never an “accident.” It is the predictable output of a business decision.
The Reality of Trampoline Injuries in Anna, Texas
Anna is one of the fastest-growing cities in North Texas. This rapid suburban expansion creates a concentrated market for the trampoline industry. Nationally, trampolines send more than 300,000 Americans to the emergency room every year. In a high-growth corridor like Collin County, those statistics become medical realities for thousands of families.
The American Academy of Pediatrics (AAP) has advised against recreational trampoline use since 1999. They reaffirmed this position in 2012 and 2019, stating clearly that trampolines should not be used at home and discouraging routine recreational use even at supervised venues. Yet, manufacturers like Jumpking, Skywalker, and Bouncepro sell products that the AAP has warned against for over a quarter of a century.
When you take your child to a commercial park, you expect a higher standard of care. You assume that because you paid an admission fee, the park is safer than your neighbor’s backyard. The medical literature proves the opposite. According to Kasmire et al. in the journal Pediatrics, commercial trampoline park injuries are roughly 21% more likely to be fractures or dislocations than injuries sustained on home equipment.
Furthermore, a 2024 study by Teague et al. in Pediatrics tracked 13,256 injuries across 8.4 million jumper-hours. They found that foam-pit and inflatable-bag attractions produce injuries at a rate of 1.91 per 1,000 jumper-hours, while high-performance jumping areas produce 2.11 per 1,000. For a busy park in North Texas, these rates mean a significant injury is a daily certainty, not a rare occurrence. Up to 1.6% of all pediatric emergency department trauma visits are now trampoline-related, according to the 2024 American Journal of Roentgenology.
These numbers are why we have built our firm to handle these specific, catastrophic cases. Managing Partner Ralph Manginello brings 25+ years of experience in federal and state courts to every case. He has gone head-to-head with Fortune 500 corporations like BP, Walmart, and Amazon. The parent conglomerates behind the big trampoline park chains don’t intimidate us. We have already fought—and won—those fights.
The Physics of a Catastrophe: Why the Double-Bounce Happens
The most common catastrophic injury mechanism we see is the double-bounce.
Imagine a Saturday afternoon at a Sky Zone or Urban Air serving Anna families. The court is packed. A 200-pound adult lands on a trampoline bed at the same instant a 60-pound child is pushing off it. In that second, physics takes over. Kinetic energy transfer can multiply the child’s launch force by up to 4x. The child is no longer jumping; the child has become a projectile thrown by a catapult.
This energy transfer produces impact forces that a child’s skeletal system is not engineered to handle. We routinely document comminuted femoral shaft fractures requiring ORIF (open reduction internal fixation) with intramedullary nailing. We see Salter-Harris Type II fractures of the distal tibia—injuries to the growth plate that can lead to permanent limb-length discrepancy.
ASTM F2970, the industry standard written by the trampoline park industry itself, requires parks to operationalize age and weight separation. When a park ignores this rule to keep throughput high, they aren’t being careless. They are making a margin decision that they know—by their own written standards—increases the risk of a child’s bone snapping like a dry twig.
The Waiver is Not a Wall: How We Fight Back in Texas
The first thing the park’s insurance adjuster will tell you is: “You signed a waiver. You have no case.”
In Texas, that is a legal bluff. Our firm includes associate attorney Lupe Peña, who used to sit on the other side of the table. He spent years defending insurance companies and recreational businesses against injury claims. He knows exactly which waiver clauses hold up and which ones Texas courts will throw out.
Waivers in Texas cannot release gross negligence. In Harris County, a jury awarded $11.485 million—including $6 million in punitive damages—against the operator of Cosmic Jump after a teenager fell through a torn trampoline slide onto concrete. The waiver was signed. The jury found gross negligence anyway.
Furthermore, Texas courts follow the Munoz v. II Jaz Inc. doctrine. A parent generally cannot bind a minor child to a pre-injury waiver of the child’s personal cause of action. While the Texas Supreme Court’s 2025 decision in Cerna v. Pearland Urban Air enforced a delegation clause regarding arbitration, it did not eliminate the underlying liability of the park.
If your family’s primary language is Spanish, we have a unique advantage. Lupe Peña is a native Spanish speaker who represents our clients directly. Under the Delfingen US-Texas, L.P. v. Valenzuela doctrine, a Texas court may deny enforcement of an agreement if the park provided an English-only waiver and the patron lacked English literacy. If you were pressured to sign an iPad waiver in English while waiting in line at a park in McKinney or Allen, you may have never formed a valid contract.
Don’t let a piece of paper stop you from seeking justice. We run a five-vector attack on every waiver that comes across our desks. We know which defenses the insurance companies deploy first because we’ve seen them from the inside.
Identifying the Deep Pockets: Corporate Archeology in Trampoline Cases
When we say “we are suing the trampoline park,” we aren’t just looking at the local LLC. We perform a deep corporate archeology on every case to find the money that has been intentionally shielded.
Major chains use layered corporate structures to hide assets. “Unleashed Brands,” “Sky Zone, Inc.,” and “Altitude Franchise Holdings” are the entities that control the safety manuals and the training protocols, but your lawsuit might initially only name a local “Anna Jump LLC” that has zero assets.
We go upstream. We trace the ownership to the private equity sponsors like Palladium Equity Partners or Seidler Equity Partners. We look for the franchisor’s “additional insured” coverage and the $25M+ excess towers that national chains carry.
Recent arbitrations prove this strategy works. In the Damion Collins v. Urban Air case, which resulted in a $15.6 million award for a quadriplegic plaintiff, the franchisor (UATP Management, LLC) was held responsible for 40% of the fault. The arbitrator found there was a “systemic failure” to implement safety changes. We don’t stop at the local manager; we hold the conglomerate accountable.
The 48-Hour Evidence Gap in Anna
The evidence that will win your child’s case is disappearing while you read this.
Park surveillance systems are often set to overwrite in as little as 7 to 30 days. Incident reports get “revised” by management to remove damaging admissions like “monitor was distracted.” Waiver kiosk databases can be purged on 72-hour cycles.
Our firm doesn’t wait for a lawsuit to start work. Within 24 hours of your retention, we send a comprehensive spoliation letter by certified mail to the park, the franchisor, and the insurer. We demand the preservation of:
- Multi-angle surveillance footage (all cameras, all angles).
- The original incident report (with metadata showing any edits).
- The court monitor’s shift time-clock records and training file.
- Daily inspection logs and maintenance records.
- The exact version of the kiosk waiver you signed.
Every minute the park delays a 911 call or pressures you for a “friendly statement,” they are buying time for the evidence to overwrite. We send the preservation demand before the park attendants even finish their next shift.
Catastrophic Pediatric Injuries: Why a “Broken Leg” is never just that
In the world of trampoline injuries, a “broken leg” is a medical oversimplification.
A comminuted femoral shaft fracture in a child whose bones are still developing is a multi-year orthopedic challenge. If a growth plate is involved (a Salter-Harris fracture), your child may experience permanent limb-length discrepancy or angular deformity as they grow. They might need a corrective osteotomy at age 14 because of a jump they took at age 8.
We also litigate cases involving SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). This is a pediatric-specific phenomenon where a child’s highly flexible spine allows for a permanent spinal cord injury even when the X-rays or CT scans look “normal.” Many ERs miss this diagnosis, treating a child for a “panic attack” when they are actually suffering a spinal cord stroke.
And then there is Rhabdomyolysis. We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdo and acute kidney failure. We see the same muscle and organ breakdown in children who jump for two hours straight in an 85-degree indoor park in North Texas without adequate hydration. If your child has cola-colored urine or severe muscle swelling after a visit to a park, they are in a medical emergency.
We use biomechanical engineers, pediatric orthopedic surgeons, and life-care planners to calculate the true cost of these injuries. We don’t settle for the ER bill; we recover for the next fifty years of your child’s life.
Frequently Asked Questions for Anna Families
Can I sue if I signed a waiver for my child at the Frisco or McKinney park?
Yes. In Texas, a parent’s signature generally cannot waive a child’s future right to sue for personal injuries. Additionally, no waiver in Texas can release a company from gross negligence. If the park failed to follow ASTM F2970 or its own safety manual, the waiver is often legally irrelevant.
How much is my child’s trampoline injury case worth?
Settlements for serious pediatric fractures often range from $500k to $2M. Catastrophic cases involving brain or spinal injuries frequently reach multi-million dollar figures, like the $15.6M Urban Air arbitration or the $11.485M Cosmic Jump verdict.
What if my child was double-bounced by another kid?
The park’s duty is to supervise and separate jumpers. They cannot outsource their safety responsibility to other children. If the attendants failed to stop a size-mismatch jump, the park is liable for the resulting injury.
How long do I have to file a claim in Texas?
The statute of limitations for personal injury is generally two years. However, for minors, the clock is tolled until they turn 18, meaning they have until age 20 to file. But remember: the evidence (video and witness memory) is gone in weeks. Call us today.
What if we aren’t sure our child’s injury was the park’s fault?
That is what investigators and biomechanical engineers determine. Most parents “had no idea” until an expert examined the foam pit depth or the attendant-to-jumper ratio. Let us do the investigation for you at zero upfront cost.

The Hidden Risks of Anna’s Backyard Trampolines
While commercial parks are high-risk environments, backyard trampolines in Anna’s newer subdivisions present theirs own unique dangers. Texas law holds homeowners accountable under the attractive nuisance doctrine when a child wanders onto a property and is injured by a hazardous condition the owner failed to secure.
Homeowners’ insurance policies in Collin County exclude trampoline injuries more often than they cover them. If your neighbor’s trampoline injured your child, we look at every layer: the homeowner’s General Liability, any existing umbrella policies, and the manufacturer’s product liability.
Jumpking, Skywalker, and the Bouncepro models sold through Walmart all carry owner’s manuals that warn against use by children under six and multi-jumper use. If the manufacturer’s warnings were inadequate or the product was defectively designed, we hold the manufacturer accountable. We advance the costs for forensic engineers to inspect the frame welds, mat tension, and net integrity of your backyard equipment.
The Rhabdo Bridge: A $10 Million Accountability Record
On the University of Houston campus and in courtrooms across Texas, we are fighting a $10 million lawsuit involving rhabdomyolysis—the same muscle breakdown that can kill after an extended trampoline session.
A child jumping for ninety minutes in a heated indoor park in Anna, drinking one soda, and arriving at the ER two days later in acute kidney failure is not a mystery to us. We have the medical experts, the nephrology consultants, and the litigation playbook to prove that the park’s failure to monitor heat and hydration was a direct cause of your child’s trauma.
The industry knows. We know. Now we make them pay.
