“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 how Kaitlin “Kati” Hill described the moment her three-year-old son, Colton, suffered a broken femur at a trampoline park. Her warning, shared over 240,000 times on social media, included five words that haunt every parent in the City of Belton whose family has been touched by this industry: “We had no idea.”

At Attorney911, led by founding partner Ralph Manginello with over 25 years of trial experience, we see the aftermath of that “no idea” every day. Since 1998, we have fought for families in the City of Belton and across Texas who were told their child’s injury was a “freak accident” or an “inherent risk.” We know better. A shattered tibia on a Saturday afternoon at a park near I-35 or a traumatic brain injury in a Belton backyard is rarely an accident. It is the predictable output of a system that puts corporate margins ahead of pediatric safety.

We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure—the same catastrophic muscle and organ breakdown we see in children who jump for ninety minutes in a heated indoor facility in the City of Belton and arrive at an emergency room two days later in renal crisis. Our team includes associate attorney Lupe Peña, who used to defend insurance companies and recreational businesses from these exact claims. He knows their playbook because he helped write it. He knows which waiver clauses the Texas courts will strike down and which “independent” medical examiners are paid to minimize your child’s pain.

If your child was injured at a trampoline park or on a defective home trampoline in the City of Belton, you are likely standing at a bedside at McLane Children’s Baylor Scott & White or another regional trauma center. You may be looking at a body cast or a surgical incision and wondering how a signed piece of paper at a kiosk could possibly take away your child’s right to be whole. The answer is that it can’t. In Texas, the law protects children even when their parents have signed a waiver. We know the attack vectors, the ASTM standards, and the corporate archeology required to pierce the layers of LLCs shielding the multi-million dollar insurance towers. The case starts with a phone call to 1-888-ATTY-911. Hablamos Español. No fee unless we win.

The Reality of Trampoline Parks: A Business Decision, Not an Accident

When you walk into a commercial facility in the City of Belton, the music is loud, the lights are neon, and the marketing promises “active family fun.” What they don’t tell you is that the industry is largely self-regulated. While Europe operates under the mandatory EN ISO 23659:2022 standard, the United States relies on ASTM F2970—a voluntary standard effectively written by the trampoline park industry itself.

In a landmark Harris County case, the operator of Cosmic Jump was hit with an $11.485 million jury verdict, including $6 million in punitive damages. A sixteen-year-old fell through a rip in a trampoline slide and struck the concrete floor beneath. The park had signed waivers from every guest, but the jury found gross negligence anyway. They found that the park had actual knowledge of the tear but consciously chose to keep the attraction open.

This is the “margin over safety” architecture we fight. Most parks in and around the City of Belton, including various national chains that populate Central Texas, operate with an attendant-to-jumper ratio that collapses during peak hours. ASTM F2970 has specific provisions for court monitoring, but on a Saturday afternoon when the throughput is high, those monitors—often teenagers with less than four hours of training—can’t possibly enforce age and weight separation. When a 200-pound adult lands near a 50-pound child, the result is a “double-bounce” energy transfer that can multiply the child’s launch force by 4x. The child isn’t jumping; they are being launched like a projectile.

Why Your “Signed Waiver” Does Not End Your Case in Texas

The most common tactic used by insurance adjusters when calling a parent in the City of Belton is the “Waiver Wave.” They point to the kiosk agreement you signed and imply your case is over before it begins. One of our attorneys, Lupe Peña, used to raise these defenses for the other side. Now, he uses the Munoz and Dresser doctrines to dismantle them.

The Parental Indemnity Barrier: Munoz v. II Jaz, Inc.

The most important thing for any parent in the City of Belton to understand is that in Texas, you cannot sign away your minor child’s personal cause of action. Under the seminal case Munoz v. II Jaz, Inc. (1993), Texas courts held that parental pre-injury waivers of a minor’s claim are void against public policy. While your signature might impact your own derivative claims for medical bills, it does NOT bar your child from seeking justice for their own pain, suffering, and permanent impairment.

The Fair Notice Doctrine: Dresser v. Page Petroleum

Even for adult victims in the City of Belton, a waiver must pass the “Fair Notice” test established in Dresser Industries, Inc. v. Page Petroleum, Inc. This requires:

  1. Express Negligence: The waiver must specifically use the word “negligence” to be enforceable.
  2. Conspicuousness: The release language cannot be buried in the fine print. It must be bold, capitalized, or otherwise stand out so that a reasonable person would see it.

Most kiosk waivers at national chains fail one or both of these tests. When we depose the park’s manager, we don’t ask if the waiver was signed. We ask why the safety provisions of ASTM F2970 Section 10 were ignored, and we show that the waiver didn’t cover the park’s decision to operate with half the required staff.

The 48-Hour Evidence Clock: Why Belton Families Must Act Fast

We cannot overstate the urgency of evidence preservation. The trampoline park’s risk management team is working before the ambulance leaves the parking lot. In the City of Belton, your child’s recovery depends on what we can freeze in time this week.

  • Surveillance DVRs: Most park security systems overwrite footage every 7 to 30 days. If we do not send a formal spoliation letter within the first few days, the video of the double-bounce or the harness failure disappears forever.
  • Incident Reports: The report you filled out the day of the injury is often “revised” on the park’s computer system within 48 hours. Our digital forensic protocols allow us to pull the metadata and see every edit made by corporate risk managers.
  • Waiver Kiosks: Many waiver databases purge version history on a 72-hour rolling cycle. We use Wayback Machine captures and forensic extraction to prove what the screen actually looked like when you touched “I Agree.”
  • The Equipment: Foam pits are refilled, springs are replaced, and torn pads are swapped overnight. We demand an immediate inspection by our biomechanical engineers before the scene is altered.

If your family is dealing with a catastrophic injury, don’t wait for the park to “check in” on your child. Call us at 888-ATTY-911. We advance every expense for investigators and experts so your child’s recovery fund stays intact.

Catastrophic Pediatric Injuries: Beyond the Emergency Room

A “broken leg” at age eight is not just a broken leg. It is a potential lifetime of orthopedic monitoring. At our firm, we look at the medicine with the same specificity we bring to the law. We represent the parent who is being told their child has a Salter-Harris fracture—an injury to the growth plate.

If that growth plate is destroyed at age nine, the bone may stop growing or grow at an angle, leading to a permanent limb-length discrepancy that requires corrective osteotomy years later. A cervical spine injury (SCI) in a child can manifest as SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. A child may have a “normal” CT scan in the trauma bay but be suffering from cord ischemia that leads to progressive neurological decline.

The Rhabdomyolysis Bridge

Our $10 million lawsuit against a major university for rhabdomyolysis is the blueprint for how we handle trampoline exertion cases. Exertional rhabdomyolysis occurs when muscle tissue breaks down and releases myoglobin into the bloodstream, poisoning the kidneys. This happens when children jump for extended periods in facilities without adequate hydration or temperature controls. We know the CK (creatine kinase) levels to look for, and we have the nephrology experts ready to testify that the park’s lack of a hydration protocol was the direct cause of your child’s kidney failure.

Who is Responsible? Piercing the Corporate Shield

When we file a lawsuit for a City of Belton family, we don’t just sue the local LLC. We perform corporate archeology to find the deep pockets. The defendant stack typically includes:

  1. The Operator LLC: The local entity with a likely $1 million policy.
  2. The Franchisee: Often a multi-unit owner with an umbrella policy.
  3. The Franchisor: Entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings, who mandate the training materials that failed your child.
  4. The Parent Company: Sky Zone, Inc. (formerly CircusTrix, backed by Palladium Equity Partners) or Unleashed Brands (backed by Seidler Equity Partners).
  5. The Manufacturer: If a spring failed or a net tore, the product manufacturer is on the hook for design or manufacturing defects.

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.” We take the difficult cases because we know how to pierce these layers. We’ve done it against BP, Walmart, and Amazon. We aren’t intimidated by the private equity lawyers defending national chains.

Acknowledging the Truth: A Letter to Belton Parents

You might be feeling a heavy weight of guilt right now. You signed the waiver. you paid the admission. You let them jump because you wanted them to have fun.

Look—I have spent 25 years fighting this battle, and the first thing I tell parents is this: this is not your fault. none of it. You were a customer who paid for a service. ASTM F2970 placed the duty of safety squarely on the park. They were the ones responsible for training the teenagers watching the court. They were the ones responsible for rotating the foam blocks so they didn’t compact to the concrete floor. They were the ones who saw the profit in “Toddler Time” without investing in the safety equipment and monitor ratios required to keep toddlers safe.

You were a parent showing your child a good time. They were a corporation making a calculated risk with your child’s safety. We will make them pay for that calculation.

Frequently Asked Questions for City of Belton Families

Can I sue if I signed the electronic waiver at the park?

Yes. In Texas, a parent generally cannot waive a child’s right to sue for personal injuries. Furthermore, if the waiver doesn’t meet the “Fair Notice” and “Conspicuousness” standards, it may be void even for adults. We attack these waivers on five different legal fronts.

What should I do if the park manager tells me they won’t call 911?

Call 911 yourself immediately. Multiple reviews of national chains, including the Urban Air in Southlake, TX, mention that staff were instructed to downplay injuries and not call for an ambulance. If this happened to you, it is evidence of a systemic policy of conscious indifference—a key element of gross negligence.

How much is a trampoline injury case worth?

Every case is different, but catastrophic pediatric cases can settle or result in verdicts in the millions. A Salter-Harris growth plate fracture at age eight is a significant damage calculation that must include a decade of medical monitoring and possible future surgeries. National industry data shows $5 million+ benchmarks for permanent cervical injuries.

My child’s injury was caused by another kid. Is the park still liable?

Absolutely. The park has a non-delegable duty to supervise and enforce safety rules. If they allowed a weight mismatch (an adult and a child) on the same bed, or failed to stop aggressive jumping that led to a collision, the park’s failure to supervise is the operative negligence.

How do I afford a lawyer and all these medical experts?

You pay us nothing upfront. We work on a contingency fee basis, and we advance every cost—the biomechanical engineer, the pediatric orthopedic surgeon, the life-care planner. If we don’t win your case, you owe us nothing for our time or the thousands of dollars we spent building the file.

What if we aren’t City of Belton residents and our child was hurt there?

We handle cases nationwide. Our Texas offices are our base of operations, but our knowledge of the laws governing trampoline injuries across all 50 states allows us to represent families wherever the park is located. We travel, we investigate, and we win.

The Moat: Why Attorney911 Is Different

Most personal injury firms handle a trampoline case like a standard slip-and-fall. They don’t know the specifics of ASTM F381 for backyard trampolines or F2970 for commercial courts. We do. We’ve memorized the standards better than the park’s own management.

We include an attorney who used to sit on the other side of the table—defending these businesses for the insurance companies. He knows exactly how they calculate “nuisance value” and exactly what evidence forces them to move toward a multi-million dollar settlement. We have litigated against the largest corporate entities in the world, including BP after the Texas City refinery explosion. The fleet of lawyers hired by private equity sponsors like Palladium Equity or Seidler Equity doesn’t scare us. We’ve already beaten their peers.

We advance the costs for the most sophisticated experts in the field:

  • Biomechanical Engineers to model the energy transfer of the double-bounce.
  • Pediatric Orthopedic Consultants to explain the growth-plate prognosis to a jury.
  • Life-Care Planners to calculate the 40-year medical costs of a spinal cord injury.

Final Action for City of Belton Families

Every minute the park delays a 911 call, a refund, or an apology is a minute the surveillance gets closer to overwriting. The evidence you need to win your case is literally disappearing while you wait.

You don’t need “a lawyer.” You need a firm that can quote the foam-pit depth requirements of ASTM F2970 from memory and one that is already litigating the pathology of rhabdomyolysis in a $10 million institutional case. That’s our firm. That’s Ralph Manginello.

Call 1-888-ATTY-911 right now. We are available 24/7. Hablamos Español. Your child’s case depends on what gets preserved this week. Let’s make sure the corporate parent behind the park understands that your family’s rights aren’t for sale.

Understanding the Liability Stack in Central Texas

Trampoline parks serving the City of Belton often belong to national franchise networks. While current data shows no dedicated park within the Belton city limits, families frequently travel to nearby Temple, Killeen, and Waco to visit attractions like Xtreme Jump in Temple—the 60,000 square foot flagship of its chain and one of the largest jump facilities in Central Texas.

When an injury occurs at a facility like Xtreme Jump Temple or an Urban Air in Waco, the local LLC is merely the first layer of a complex defendant architecture. We identify the franchisee, the franchisor (like Urban Air Franchise Holdings), and the private equity sponsor. Under the doctrine of apparent agency—established in Texas by Baptist Memorial Hospital System v. Sampson—the franchisor is often reachable because their branding, uniforms, and website lead you to believe you are doing business with the national brand, not an anonymous local LLC.

The Medical Trajectory of a Trampoline Injury

If your child is being treated at a facility like McLane Children’s in Temple, you are entering a long-term medical journey. We engage with life-care planners early because the medical bills you see today are only the beginning.

Traumatic Brain Injury (TBI) and the Developing Brain

A head strike on an unpadded frame or concrete floor can cause a Diffuse Axonal Injury (DAI)—a shearing of the brain’s long connecting fibers. In a developing child, a TBI doesn’t just damage existing tissue; it disrupts the formation of future neural pathways. We retain pediatric neuropsychologists to document the academic regression and executive function damage that might not be fully visible for six months to a year after the crash.

Spinal Cord Injury Without Radiographic Abnormality (SCIWORA)

The pediatric cervical spine is uniquely flexible. A child can suffer a spinal cord injury even when their vertebrae aren’t fractured or dislocated. This condition, SCIWORA, is often misdiagnosed as “neck strain” until the neurological symptoms worsen. We look for whether the park’s staff was trained to recognize the signs of a cervical injury and whether they inappropriately moved your child, extending the cord ischemia.

The Salter-Harris Classification

If your doctor mentions a “Salter-Harris fracture,” they are referring to a break through the physis, or growth plate.

  • Type II: Through the physis and metaphysis (most common).
  • Type III: Through the physis and epiphysis into the joint.
  • Type IV: Through all three layers.
    Types III and IV carry a high risk of growth arrest. we ensure the insurance carrier understands that settlement must account for a lifetime of orthopedic monitoring.

The Hidden SANITATION Hazards

Most Belton families never consider what happens inside a foam pit. These pits are bacterial reservoirs. Polyurethane foam blocks are porous; they absorb sweat, saliva, blood, and urine. Because the interior of the blocks cannot be sanitized, bacteria like MRSA can colonize the pit.

If your child developed a staph infection, cellulitis, or even necrotizing fasciitis following a visit to a park, the park’s failure to maintain a sanitary environment is a breach of premises liability. We pull the cleaning logs and chemical invoices to prove the park was operating a biological hazard in the guise of a play area.

The Manufacturer Defect Vertical: Backyard Trampolines

While commercial parks have a high injury density, the backyard trampoline in the City of Belton produces the largest volume of ER visits. If a Jumpking, Skywalker, or Bouncepro trampoline frame weld fails, or the netting tears from UV degradation sooner than promised, the manufacturer bears strict product liability.

We look at the owner’s manual (IFU) and the CPSC recall history. Jumpking had 1 million units recalled in 2005 for breaking welds. Skywalker has historical enclosure strap failures. Walmart’s private-label Bouncepro has been recalled for netting that fails under impact. Under the doctrine of Bolger v. Amazon and Oberdorf v. Amazon, even the online marketplace or retailer who sold you a defective off-brand trampoline can be held liable as a “seller.”

Attractive Nuisance and Belton Neighborhoods

If a neighbor’s kid wandered onto your property and was injured on your trampoline, Texas law applies the Attractive Nuisance Doctrine. This holds that a landowner can be liable for injuries to child trespassers if they have a condition (like a trampoline) that they know is likely to attract children who cannot appreciate the danger.

Homeowners insurance policies in Belton increasingly EXCLUDE trampoline injuries. If your policy has this exclusion, you could find yourself personally exposed. We help families navigate these sensitive situations by identifying the manufacturer or the original retailer’s liability to shift the burden from the individual homeowner.

The Step-by-Step Path to Accountability

How do we actually build your case? We don’t just “handle” it. We engineer it:

  1. Litigation Hold (Day 1): We send a formal preservation demand for all surveillance, digital logs, and physical components.
  2. Scene Investigation (Day 2): We send a photographer and forensic investigator to Belton or Temple to document the current conditions before they are cleaned.
  3. Medical Chronology: Our in-house medical experts review every page of the EMS run sheet and hospital chart.
  4. Corporate Discovery: We subpoena the franchisor’s audit reports. We want to see if corporate knew the local park was failing its safety checks.
  5. Biomechanical Modeling: We reconstruct the impact. We prove the force exceeded what any child’s bone could withstand.
  6. The Stowers Demand: We make a policy-limits demand to the insurer that puts them on the hook for “Bad Faith” if they refuse a reasonable settlement.

As client Glenda Walker said, “They fought for me to get every dime I deserved.” We bring that same level of aggression to every trampoline case.

Why Time is the Enemy

If you are reading this and your child was hurt a month ago, don’t assume you’ve missed the boat. The statute of limitations in Texas gives you time. But the evidence is dying.

The employee who saw your child fall? They were likely a student from Mary Hardin-Baylor or a local high school who has since moved on to another job. The manager who admitted “the court was too full” has probably been reassigned. The surveillance video is almost certainly gone.

BUT HERE IS THE THING: Even if the video is gone, we know how to use “Adverse Inference.” When a park’s video “glitches” or is deleted after we’ve sent a warning, we tell the jury to assume the footage was devastating to the park. A Georgia jury awarded $3.5 million over a video glitch. We know where the pressure points are.

What Your Case is Really Worth: The Life Care Plan

Every parent’s biggest fear is that they will settle their case today and realize five years from now that their child needs more help. In a catastrophic pediatric case—like a cervical spine injury or a severe TBI—we develop a Life Care Plan with a certified specialist.

We forecast the cost of:

  • Wheelchair replacements every five years.
  • Home and vehicle modifications.
  • Special education tutors and academic aides.
  • Lifetime psychiatric care for the PTSD and anxiety that follow a trauma.
  • Lost future earning capacity—quantifying what your child would have earned over a 40-year career had they been healthy.

We don’t settle for “medical bills plus a little extra.” We settle for the amount that protects your child’s future after you are gone.

The Moat: Our Credential Stack

Ralph Manginello started this firm in 2001 after gaining experience in high-stakes federal court litigation. Since then, he has focused on one goal: making sure families in the City of Belton and across Texas have a fighter in their corner.

Lupe Peña adds the “Insider Advantage.” Because he defended these same corporations, he can tell us exactly which waiver arguments will be laughed out of court and which ones need a strategic pivot.

We are not just “injury lawyers.” We are advocates for safety in an industry that refuses to police itself. Your child’s life changed in one bad jump. The park’s insurance carrier is hoping you’ll just accept their small offer and go away. We won’t.

Our team litigated the BP Texas City refinery explosion. We’ve gone toe-to-toe with Walmart, Amazon, FedEx, and UPS. The corporations backing Urban Air and Sky Zone don’t bring anything we haven’t beaten before.

FAQ: State-Specific Laws for Belton Families

Is the law the same in Temple as it is in Belton?
Yes. For premises liability and waiver enforceability, the laws of the State of Texas govern. Both cities are in Bell County, meaning your case would likely be heard in the Bell County District Court in Belton. We are local.

How does “Comparative Fault” work in a trampoline case?
Texas follows a Modified 51% bar. If you or your child are found to be 51% or more at fault, you recover zero. The trampoline park will always try to blame the child (“they were doing unauthorized flips”). We counter this by showing that children (especially under 7) are legally considered more susceptible to risk and that the park’s duty to supervise overrides the child’s error.

What if my child was hurt at a summer camp in Belton?
Summer camps, schools, and daycares have a high duty of care. Peer-reviewed medical literature by the AAP has advised against trampolines in these settings since 1999. If a camp included trampolines in its program against medical consensus, their liability is enormous.

Why should I call Attorney911 instead of a firm I see on TV?
TV firms are often “settlement mills.” They want to process 1,000 cases a month. We take a different approach. We are a family law firm in the original sense. As Chad Harris said, “You are FAMILY to them.” We build each case for trial, and we don’t accept any offer that doesn’t fully fund your child’s Life Care Plan.

Closing Authority: The Kill Shot

What happened to your child at the trampoline park wasn’t an accident—it was the output of an architecture designed by corporate parents and private equity sponsors who value through-put more than safety. ASTM F2970 was written by the industry to give itself a floor; most parks in Central Texas operate below even that floor.

The waiver at the kiosk was written by corporate counsel who knew it wouldn’t hold. The surveillance is designed to overwrite before you even have a chance to call a lawyer. They are counting on your silence. They are counting on your guilt.

Don’t give them either.

Attorney911 was built for exactly this fight. We have the 25 years of experience, we have the former defense-counsel edge, and we have the active $10 million rhabdomyolysis litigation results to prove we know the medicine and the accountability theories. Your child’s recovery fund starts with one phone call.
