One second. One bounce. One bad landing at a trampoline park is all it takes to change a family’s life in the City of Petronila forever. You were likely at a birthday party or a weekend outing at one of the parks serving the Nueces County area, perhaps making the short drive down Highway 77 or I-37 toward the clusters of entertainment centers in nearby Corpus Christi. You signed the waiver on the iPad at the front desk because the line was long, your kids were excited, and the teenage attendant was rushing you through the “registration” process. Now, you’re sitting in a trauma bay at Driscoll Children’s Hospital, watching a surgeon explain what a Salter-Harris fracture means for your nine-year-old’s future.

We’ve spent 25 years standing with families in these exact moments. Since 1998, Ralph Manginello and our team at Attorney911 have held corporate defendants accountable for putting profit margins ahead of child safety. Whether your injury happened at the Urban Air on Staples Street, the Jumping World in Corpus Christi, or on a Jumpking trampoline in your own backyard in the City of Petronila, we know the architecture of these cases. We know that while the park manager is handing you an “incident report,” their risk management team is already preparing to tell you that you “assumed the risk” and “signed away your rights.”

They’re wrong. That piece of paper is not an absolute shield. In Texas, we have a history of breaking through these corporate barriers. We bring federal court experience and a primary source of knowledge that most firms lack: an attorney on our team, Lupe Peña, who used to defend insurance companies and recreational businesses against these exact claims. He knows the playbook they are using against you right now because he helped write it. Now, he uses that insider knowledge to dismantle it.

The Worst Scream: Why We Fight for City of Petronila Families

Parents in the City of Petronila often hear the same thing after an accident: “It was just a freak accident.” But as Kaitlin “Kati” Hill told ABC News after her three-year-old son Colton’s femur was snapped at a trampoline 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.” Kati later added, “We had no idea. We would have never put our baby boy on a trampoline if we would have known.”

That feeling of “we had no idea” is the result of a multi-million-dollar marketing machine designed to make you believe these parks are as safe as a neighborhood playground. They aren’t. While parks like Sky Zone and Urban Air advertise “safe family fun,” the data tells a different story. According to the American Journal of Roentgenology (2024), up to 1.6% of all pediatric emergency department trauma visits in the United States are now related to trampolines.

When your family is dealing with the fallout of a catastrophic injury, you don’t need a generalist. You need a firm that knows that ASTM F2970 is the industry standard for commercial trampoline courts. You need a lawyer who knows that the International Organization for Standardization published EN ISO 23659:2022 as a mandatory safety standard in Europe, while the US industry still relies on voluntary rules they wrote for themselves. We understand that in the City of Petronila, the salt air and Gulf Coast humidity don’t just affect our cars—they degrade the polypropylene netting and steel springs of backyard trampolines, making a collapse inevitable if the equipment isn’t maintained to ASTM F381 standards.

Our firm is currently litigating a $10 million lawsuit involving rhabdomyolysis and acute kidney failure. This is the same catastrophic muscle breakdown we see in children who are double-bounced or forced into extended-jumping sessions in overheated indoor facilities. We know the medicine, we know the engineering, and we know how to win.

The Evidence Clock: Why You Cannot Wait in City of Petronila

The most critical thing you need to know right now is that the evidence of what happened to your child is disappearing. Most families think they have two years to file a lawsuit because of the Texas statute of limitations. While that’s technically true (and the clock is often tolled for minors until they turn 18), the evidence clock is much shorter.

In our experience, trampoline park surveillance DVR systems are typically set to overwrite every 7 to 30 days. The “incident report” you saw the manager typing might be “revised” by corporate risk management within 48 hours. The attendant who was on their phone instead of watching the court might quit their job next week.

If you were injured at a park near the City of Petronila, our spoliation letter goes out within 24 hours of you hiring us. We demand the preservation of:

  • Multi-angle surveillance footage: We don’t just want the clip they choose to show you; we want the full day’s data to show the pattern of understaffing.
  • Kiosk metadata: We want to see how long you were actually given to read that 20-page waiver. If you weren’t given a Spanish translation and Spanish is your primary language, the Delfingen doctrine in Texas may make that entire waiver void.
  • Attendant training logs: We want to know if the “court monitor” had the minimum training required by the chain’s own operations manual.
  • Maintenance records: We want to see the daily inspection logs. If they’ve signed off on a “safe” foam pit for 90 days straight but the foam is compacted to half its required depth, that is gross negligence.

As client Angel Walle said of our firm, “They solved in a couple of months what others did nothing about in two years.” Speed is our strategy.

Texas Law and the Myth of the “Unbreakable” Waiver

The insurance adjusters for chains like Sky Zone (now owned by Palladium Equity Partners) or Urban Air (owned by Unleashed Brands/Seidler Equity) want you to believe that the waiver you signed at the kiosk ended your case before it began. In the City of Petronila and throughout Texas, that simply isn’t true.

First, under the landmark Texas case Munoz v. II Jaz Inc. (1993), a parent generally cannot sign away a minor child’s right to sue for personal injuries. Your signature might affect your own claims, but your child’s right to be made whole usually survives.

Second, Texas law follows the “fair notice” doctrine established in Dresser Industries v. Page Petroleum. A waiver must be conspicuous and use express negligence language. If the waiver was buried in a tiny font on a flickering iPad screen near a noisy birthday party, it may not be enforceable.

Third, no waiver in Texas protects a park from gross negligence. We look at the $11.485 million verdict in Max Menchaca v. Cosmic Jump right here in Harris County. In that case, a 16-year-old fell through a tear in a trampoline slide onto a concrete floor. The park knew about the tear and didn’t fix it. The jury found gross negligence, and the waiver was essentially tossed aside. $6 million of that verdict was for punitive damages—money meant to punish the company for its conscious indifference to safety.

One of our attorneys, Lupe Peña, brings a unique edge to these arguments. Having sat on the other side of the table defending businesses against these suits, he knows which clauses are airtight and which ones are full of holes. He speaks Spanish fluently, ensuring that our families in Nueces County are never taken advantage of by adjusters who rely on a language gap to push through a cheap settlement. Hablamos Español.

The Mechanics of a Catastrophe: How Injuries Happen

We don’t look at a trampoline injury as an “accident.” We look at it as a mechanical failure or a supervision failure. In the City of Petronila area, we see three primary ways people are hurt:

1. The Double-Bounce Physics

The most common injury mechanism is the double-bounce. When a 200-pound adult lands on a trampoline bed at the same time a 60-pound child is pushing off, the energy transfer multiplies the child’s launch force by up to four times. The child isn’t jumping anymore; they are being launched like a projectile. This leads to what orthopedic surgeons call “trampoline fractures”—specifically proximal tibial metaphyseal fractures in young children.

2. The Foam Pit Trap

Foam pits look safe, but they are often the site of permanent paralysis. If the foam blocks are not rotated or replaced regularly (as ASTM F2970 requires), they compact. A child doing a backflip—a move often encouraged by park marketing—can land head-first and strike the concrete floor beneath the foam. This is where we see SCIWORA (Spinal Cord Injury Without Radiographic Abnormality), a pediatric-specific condition where the child’s spine is damaged even if the bones don’t look broken on a standard X-ray.

3. The Harness and Attraction Failure

As parks like Urban Air have evolved into “adventure parks,” they’ve added Sky Riders, climbing walls, and ropes courses. We look at the tragedy of Matthew Lu at an Altitude park, who fell 20 feet because an employee failed to secure his harness. The park later admitted “human error” and removed the attraction. If your child fell from a height at a park, we look for design defects in the safety equipment and training gaps in the staff.

Living with the Aftermath: Pediatric Damages in Texas

When we calculate a claim for a family in the City of Petronila, we aren’t just looking at the hospital bill. We are looking at the next seventy years. A Salter-Harris fracture—an injury to the growth plate—at age eight might mean the child’s leg grows crooked or stops growing entirely by age twelve. This requires a lifetime of orthopedic monitoring.

Our firm works with Certified Life Care Planners and biomechanical engineers to project these costs. We look at:

  • The Developing Brain: Pediatric traumatic brain injury (TBI) can affect executive function and academic performance years after the initial impact.
  • Physical Impairment: Compound fractures of the femur or tibia often require multiple surgeries and can leave a child with a measurable limp.
  • Psychological Trauma: Many children suffer from PTSD after a catastrophic fall, experiencing nightmares and a deep fear of physical activity.

We advance all of these investigation costs ourselves. You pay nothing unless we recover money for you. As client Donald Wilcox said, “One company said they would not accept my case. Then I got a call from Manginello… I got a call to come pick up this handsome check.”

Frequently Asked Questions for City of Petronila Families

Can I sue if the park monitor was a teenager?
Yes. In fact, the teen’s age is often evidence of the park’s negligence. If a park hires a 16-year-old with only two hours of training to supervise a high-risk area like a foam pit, they are violating ASTM F2970 training provisions. The park is responsible for the actions of its employees under the doctrine of respondeat superior.

What if my child was double-bounced by another child?
The park is still liable. It is the park’s duty to enforce age and weight separation rules. If an attendant allows a large teenager in the same zone as a toddler, and the toddler is launched and injured, the park has breached its duty of care.

How much is a trampoline injury case worth?
There is no “average” settlement, but catastrophic cases have resulted in multi-million-dollar recoveries. A permanent spinal cord injury can range from $5 million to over $25 million in lifetime care needs. A serious growth-plate fracture case often anchors in the $500,000 to $2 million range. We fight for every dime, as client Glenda Walker noted: “They fought for me to get every dime I deserved.”

Is there a deadline to file in the City of Petronila?
Texas law generally gives you two years, but specifically for minors, the statute is “tolled,” meaning the two-year clock doesn’t typically start until their 18th birthday. However, you should never wait this long. By then, the corporate entities have dissolved, the insurance policies have changed, and the witnesses have vanished. You need to act while the evidence is fresh.

Why Attorney911 is the Right Choice for Your Family

We are not a volume firm. We are a family-focused catastrophic injury firm that treats our clients like our own. Client Chad Harris said it best: “You are NOT just some client… You are FAMILY to them.”

We bring the same relentless energy to a trampoline park case that we brought to the BP Texas City refinery litigation. We aren’t intimidated by the private equity firms behind these parks. We know that Sky Zone’s parent company, Palladium Equity, saw $642 million in systemwide sales recently. They have the resources to pay for the damage they cause, but they won’t do it unless a firm like ours makes them.

We litigate against the largest corporations in the world—Walmart, Amazon, Coca-Cola—and we bring that same Fortune 500 litigation experience to Nueces County.
