“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.” Those were the words of Kaitlin Hill, a mother who watched her three-year-old son’s life change in an instant during a “Toddler Time” session at a trampoline park. Her warning, shared hundreds of thousands of times by parents across the country, is the reality we face every day at Attorney911. Whether it happened at an indoor adventure center in nearby Waco or on a backyard trampoline in a quiet City of Leroy neighborhood, that scream is the sound of a system failing a child.

If you are reading this in City of Leroy, perhaps sitting in a hospital room at Baylor Scott & White in Waco or McLane Children’s in Temple, you need to know one thing immediately: what happened to your child was not a “freak accident.” It was the predictable result of an industry that, for over twenty-five years, has ignored the warnings of the American Academy of Pediatrics. Since 1998, our founder Ralph Manginello has been fighting these kinds of battles. We have gone toe-to-toe with Fortune 500 corporations and multinational giants like BP. We know that the parent conglomerates behind chains like Sky Zone, Urban Air, and Altitude operate on a margin that often puts your child’s safety second to their bottom line.

At The Manginello Law Firm, we don’t just handle personal injury cases; we dismantle the corporate architecture that allows these injuries to happen. Our team 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. He knows exactly which waiver clauses in Texas are airtight and which ones are full of holes. When you call us at 1-888-ATTY-911, you aren’t getting a generalist. You’re getting a firm that holds a deep-seated knowledge of ASTM F2970 and ASTM F381—the safety standards the trampoline industry wrote for itself and then routinely violates.

The Reality of Trampoline Injuries in City of Leroy and McLennan County

While City of Leroy is a small, close-knit community, its residents are not insulated from the national epidemic of trampoline-related trauma. Nationally, more than 300,000 emergency room visits every year are related to trampolines. In a growing region like McLennan County, these numbers translate into real families facing life-altering diagnoses. Whether your child was injured during a birthday party at the Urban Air in Waco or on a Jumpking or Skywalker trampoline in your own backyard, the physics of the injury remain the same.

We understand the specific risks facing City of Leroy families. Our Central Texas climate, with its intense Sun Belt UV rays, can degrade the polypropylene netting and safety pads of a backyard trampoline in just a few seasons, leading to catastrophic enclosure failures. Meanwhile, the high-traffic weekend peaks at regional jump parks often lead to collapsed attendant-to-jumper ratios, where a single teenager is left to monitor fifty or sixty children across multiple courts. When that happens, the standard of care is breached, and we are here to hold them accountable.

With 25+ years of trial experience and admission to the U.S. District Court for the Southern District of Texas, Ralph Manginello has built a practice capable of handling the most complex litigation. We are currently litigating a $10 million lawsuit involving rhabdomyolysis and acute kidney failure—the same muscle-wasting pathology we see in children who are overexerted or crushed in trampoline park incidents. We have recovered multi-million dollar settlements for traumatic brain injury (TBI) and spinal cord injury victims. We know the medicine, we know the mechanics, and we know how to secure the compensation your child will need for a lifetime of care.

Call us 24/7 at 1-888-ATTY-911. Hablamos Español. Our associate Lupe Peña speaks with you directly. You pay nothing unless we win, and we advance every cost of the investigation, from biomechanical engineers to pediatric orthopedic specialists. Your child’s recovery fund stays intact while we fight the corporate lawyers.

The Science of the “Double-Bounce” and ASTM F2970 Violations

The most common way children are maimed at parks serving City of Leroy is through a mechanism called the “double-bounce.” It is simple physics, but the results are devastating. When a 200-pound adult or a larger teenager lands on a trampoline bed at the same moment a 50-pound child is pushing off, the energy transfer multiplies the child’s launch force by up to four times. The child isn’t just jumping; they are being catapulted into the air with a force their developing bones cannot absorb.

This is exactly why ASTM F2970, the industry’s own safety standard, requires commercial parks to operationalize age and weight separation. When you walk into an Urban Air or a Sky Zone and see a massive teenager jumping next to a toddler, you are looking at a direct violation of the standard of care. If the park failed to enforce these zones, they were negligent. If they knew the courts were overcrowded and did nothing, they may have been grossly negligent. In Texas, a finding of gross negligence can defeat that “waiver” you signed at the kiosk.

We have memorized these standards so you don’t have to. We know that F2970 also dictates foam pit depth, padding specifications, and the mandatory training hours for court monitors. Most personal injury firms handle a trampoline case like a simple slip-and-fall. We don’t. We treat it like the technical, corporate-liability battle it is. As our client Chad Harris once said, “You are NOT just some client… You are FAMILY to them.” That is how we treat every City of Leroy family that walks through our doors.

If your child was double-bounced, or if they were injured because a court monitor in Waco was looking at their phone instead of the jumpers, the clock is ticking. Surveillance video at these parks is often overwritten in as little as 7 to 30 days. We need to send a spoliation letter immediately to preserve the evidence of their negligence. Call 888-ATTY-911 now.

Dismantling the Trampoline Park Waiver in Texas

The first thing the insurance adjuster will tell a City of Leroy parent is: “You signed a waiver, so you don’t have a case.” This is a lie designed to make you go away. In Texas, a waiver is not a blank check for a park to be reckless.

Our strategy for defeating these waivers in City of Leroy cases is multi-faceted, leveraging Lupe Peña’s insider knowledge of insurance defense. First, Texas courts have long held in cases like Munoz v. II Jaz Inc. that a parent generally cannot waive a minor child’s personal cause of action. While the parent may have waived their own right to sue for medical bills, the child’s right to seek justice for their own pain, suffering, and permanent impairment remains.

Second, we look at the “Fair Notice” doctrine established by the Texas Supreme Court in Dresser Industries v. Page Petroleum. For a waiver to be enforceable in Texas, it must be conspicuous—meaning the font must be large, bold, or otherwise striking—and it must explicitly mention “negligence.” Many of the iPad waivers used at parks serving McLennan County fail these basic legal tests.

Finally, there is the “Gross Negligence” exception. A waiver can almost never protect a company from its own gross negligence. Consider the landmark case of Cosmic Jump in Harris County. A 16-year-old fell through a tear in a trampoline slide and hit the concrete floor below, suffering a traumatic brain injury because the park knew about the tear and did nothing. A Texas jury awarded $11.485 million, including $6 million in punitive damages. The waiver was signed, but it didn’t matter. The jury saw the conscious indifference to safety. That is the kind of aggressive advocacy Ralph Manginello and our team bring to every City of Leroy case.

Catastrophic Pediatric Injuries: Beyond the Emergency Room

A trampoline injury at age six is not the same as one at age thirty-six. Because children’s bones are still growing, a fracture can involve the growth plate, or the physis. In pediatric orthopedics, this is known as a Salter-Harris fracture. If the growth plate is damaged, the bone may stop growing or grow at an angle, leading to a permanent limb-length discrepancy. A child injured on a trampoline in City of Leroy today may require corrective surgeries at age ten, fourteen, and eighteen.

We also specialize in documenting Traumatic Brain Injuries (TBI). A child’s brain is still developing, and a “mild” concussion on the jump court can lead to years of academic regression, behavioral changes, and executive function deficits. We use life-care planners to calculate the true cost of these injuries—not just the initial ER bill, but the decades of therapy, special education, and lost earning capacity.

For spinal injuries, we are acutely aware of SCIWORA (Spinal Cord Injury Without Radiographic Abnormality). This is a pediatric-specific condition where a child’s spinal cord is injured even if their X-rays look normal. If your child was told they were “fine” at the ER and then developed numbness or weakness, call us immediately. We know how to work with the right specialists to prove the extent of the damage.

Whether it’s an ACL tear requiring a specialized pediatric reconstruction or the terrifying onset of rhabdomyolysis after a ninety-minute jump session, our firm has the resources to document every penny of your damages. As Donald Wilcox once said after we took his case: “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.” We don’t back down from difficult cases because we know the stakes for your child are too high.

Liable Parties in City of Leroy Trampoline Accidents

One of the reasons families in City of Leroy choose Attorney911 is our ability to identify every “deep pocket” in a case. A trampoline injury isn’t just the fault of the teenager on the court; it goes all the way up the corporate ladder.

In a commercial park case, we may sue:

  1. The Operator LLC: The local entity running the park in Waco or Temple.
  2. The Franchisor: Corporate entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings, which dictate safety manuals and training but often fail to audit their locations.
  3. The Parent Company: Major conglomerates like Sky Zone, Inc. or Unleashed Brands, often backed by private equity firms like Palladium Equity Partners or Seidler Equity Partners.
  4. The Manufacturer: The company that designed a defective trampoline bed, a failed harness on a climbing wall, or an inadequately padded indoor coaster like the Sky Rider.

In backyard cases, the liability might lie with:

  • The Manufacturer: Like Jumpking or Skywalker, especially if there was a frame weld failure or a known netting defect that led to a recall.
  • The Retailer: Walmart, Amazon, or Academy Sports, who are often liable for distributing products they know to be dangerous.
  • The Homeowner: Under the “Attractive Nuisance” doctrine, which in Texas holds people accountable if they have a dangerous item that attracts children (like a trampoline) but is not properly secured.

We have the federal court experience to handle multi-state product liability claims and the local tenacity to fight a neighborhood premises liability case. If your child wandered onto a neighbor’s yard in City of Leroy and was hurt, or if a defective part from a Walmart Bouncepro caused a fall, we are ready to file.

The Evidence Clock is Running in McLennan County

Every minute that passes after a trampoline accident in City of Leroy is a minute the defense uses to hide the truth. Trampoline parks are not just fun centers; they are risk-management machines. Before your child even reaches the hospital, the park manager is likely “finalizing” the incident report and making sure their story aligns with the corporate manual.

We have a 7-to-30-day window to secure:

  • Multi-angle Surveillance Video: To show the exact monitor-to-jumper ratio and the lack of supervision.
  • Kiosk Metadata: To prove how fast the waiver was signed and if it was even legible.
  • Maintenance Logs: To see if the foam pit had been compacted or if the mat was already torn.
  • Shift Records: To find out if the employees were being illegally overworked, a pattern identified in several Washington and Alabama labor citations against major chains.

Our spoliation letter is already drafted. It goes out within 24 hours of your call. We don’t wait for “standard procedures.” We move with the urgency that a catastrophic injury requires. Call 1-888-ATTY-911 and let us put our system to work for you.

FAQs for City of Leroy Parents

Can I sue if I signed a waiver for my child at a park in Waco?
Yes. In Texas, parents generally cannot waive a minor’s personal cause of action for injuries. While the waiver may be used as a defense, it is frequently voided or bypassed in cases of gross negligence or failure of fair notice.

How long do I have to file a lawsuit in City of Leroy?
The Texas statute of limitations for personal injury is two years. However, for minors, this clock is often “tolled” until they turn eighteen, giving them until age twenty to file. Regardless of the legal deadline, the evidence will be gone in weeks. Call us today at 1-888-ATTY-911 to preserve your rights.

What is “rhabdo” and how is it related to trampolines?
Rhabdomyolysis is the breakdown of muscle tissue that can lead to kidney failure. It can happen after extreme exertion or crush injuries. If your child has dark urine or extreme muscle pain 24 hours after jumping, go to the kidney-specialist or ER immediately. Our firm is currently litigating a $10M case on this exact medical issue.

What if my neighbor’s kid got hurt on my trampoline in City of Leroy?
You may be liable under the attractive nuisance doctrine. Check your homeowners’ policy—many unfortunately exclude trampoline injuries. We can help you look at every insurance layer, including the manufacturer’s product liability, to find the best path forward for everyone involved.

Should I talk to the insurance company?
No. Never give a recorded statement. The adjuster is not your friend; they are looking for reasons to blame your child for the injury. Tell them you are represented by Attorney911 and have them call us.
