"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 Kati Hill, a mother whose three-year-old son sustained a broken femur at a trampoline park. Her story is one that we at Attorney911 have heard variations of for over twenty-five years. Whether it happens at a birthday party at an Urban Air in South Austin or during a weekend outing at an Altitude near the I-35 corridor serving City of Creedmoor, the reality of a trampoline injury is devastating, permanent, and life-changing. If your child was injured at a trampoline park in City of Creedmoor, you are likely standing in a hospital room at Dell Children's Medical Center or a similar Central Texas trauma bay, wondering how a Saturday afternoon turned into a nightmare. You might be looking at a clipboard the park manager handed you, or re-reading the digital waiver you signed at the kiosk twenty minutes before the ambulance was called. We are The Manginello Law Firm, led by managing partner Ralph Manginello. With 25+ years of experience in catastrophic injury litigation, we have spent decades holding Fortune 500 companies and multinational corporations accountable. We have stood against teams of corporate lawyers in BP Texas City refinery litigation, and we are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure—the exact same muscle and organ breakdown…

City of Cedar Park Trampoline Park Injury and Pediatric Catastrophic Accident Attorneys Attorney911 of Houston TX deliver 25 plus years of federal court experience and former recreational defense attorney Lupe Peña’s waiver defeat playbook to hold Sky Zone Urban Air Altitude and DEFY accountable using the 11.485 million dollar Cosmic Jump Harris County verdict and 15.6 million dollar Damion Collins Urban Air arbitration for franchisor liability while mastering ASTM F2970 EN ISO 23659 2022 and AAP safety mandates to secure compensation for pediatric TBI SCIWORA Salter Harris growth plate fractures and rhabdomyolysis including backyard manufacturer defect cases against Jumpking Skywalker and Springfree throughout Central Texas with hablamos español native representation and no fee unless we win at 1-888-ATTY-911

"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 about the day a "Toddler Time" session at a trampoline park changed her family’s life forever. Colton suffered a broken femur—the strongest bone in the human body—simply because he was jumping in an environment that was never as safe as the marketing brochures promised. If your child was injured at a trampoline park in Cedar Park, you are probably feeling exactly what Kati felt: a mixture of terror, confusion, and a crushing sense of guilt. You signed the waiver at the kiosk because the line was long. You let your child onto the court because the park advertised it for their age. You believed that the "court monitors" were trained safety professionals. We are here to tell you that none of this is your fault. The guilt belongs to the corporations that prioritize profit margins over the padding on a steel frame. At Attorney911, led by Ralph Manginello with over 25 years of courtroom experience, we don’t treat trampoline injuries like typical "scrapes and bruises." We understand the physics of energy transfer that multiplies a child's launch force. We know the medical reality of Salter-Harris growth plate fractures that can stunt a child's leg growth for a decade. And we know that the "Participation Agreement" you signed in a…

At the Urban Air Adventure Park in Bee Cave, located just off Highway 71 near the Hill Country Galleria, a Saturday afternoon feels like the definition of "safe family fun." You hear the music, the laughter, and the rhythmic thud of hundreds of children launched into the air. You signed the waiver at the kiosk in thirty seconds because the line was long and your kids were vibrating with excitement. You handed them their grip socks and watched them run toward the courts. Then, the scream happens. It is a sound Kaitlin "Kati" Hill, a mother whose story we followed closely, once described as "the worst scream that you could ever have heard from a child." For Kati’s son Colton, it was a shattered femur during a "Toddler Time" session. In Bee Cave, it might be a double-bounce collision on the main court or a fall from the ropes course while a teenage monitor was looking at a smartphone. Within minutes, your child is in the back of an ambulance, likely heading down RM 620 toward Dell Children’s Medical Center in Austin. While you are sitting in a trauma bay waiting for an orthopedic surgeon to explain what a Salter-Harris growth plate fracture means for your child’s next ten years of development, the trampoline park’s risk management system is already moving. They are not moving to help you. They are moving to protect themselves. By the time you drive home from the hospital, the clock on the park’s surveillance DVR…

One bounce. One bad landing. One broken neck. That is all it takes at an indoor trampoline park in the City of Austin. You were at a Saturday afternoon birthday party on the North IH-35 corridor. You were watching your child from the observation deck, and then you weren't—because the double-bounce that launched your son occurred in less than two seconds. One moment he was laughing, and the next, he let out what Kati Hill, a mother who lived through this nightmare, called "the worst scream that you could ever have heard from a child." At the Sky Zone in Cedar Park or the Urban Air in South Austin, your family’s life can change in a single jump. You signed the waiver at the kiosk because the line was long and the software was designed for speed, not comprehension. Now, as you sit in the trauma bay at Dell Children's Medical Center or University Medical Center Brackenridge, the park’s insurance adjuster might already be calling to "check in." They are hoping you believe that the piece of paper you signed ended your case before it began. It didn't. For over 25 years, our managing partner Ralph Manginello has fought for catastrophic injury victims across the City of Austin and the State of Texas. He has gone toe-to-toe with Fortune 500 corporations like BP, Walmart, and Amazon. The parent conglomerates behind the big trampoline park chains—Sky Zone, Inc. (formerly CircusTrix LLC), backed by Palladium Equity Partners, and Unleashed Brands (the parent…

One bounce. One bad landing. One broken neck. That's all it takes for a Saturday afternoon at a Cedar Park trampoline park to transform into a lifetime of medical monitoring and forensic reconstruction. At the Sky Zone on Scottsdale Drive or the Urban Air off Ranch Road 620, a seven-year-old child can come off a court on a stretcher while their parents are still finishing the birthday party pizza. We've seen this scene replay across Texas. We've spoken to the parents who signed a waiver at a kiosk twenty minutes earlier, only to be told by a manager that the park "isn't responsible" for the shattered femur or the traumatic brain injury. Kaitlin "Kati" Hill, a mother whose story was shared a quarter of a million times on Facebook, told ABC News about the moment her three-year-old son Colton’s knees buckled: "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, like so many parents in Cedar Park, had no idea. She said, "We would have never put our baby boy on a trampoline if we would have known." We publish this guide because you deserve to know what the industry won't tell you. Attorney911 is launching our dedicated trampoline injury practice from a foundation of 25+ years of catastrophic injury experience. Our managing partner, Ralph Manginello, has spent over two decades holding Fortune 500 corporations accountable—from the BP Texas…

"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’s femur—the strongest bone in the human body—snapped during a morning session at a trampoline park. Her warning was shared 240,000 times by parents who, like her, had no idea that the "Toddler Time" advertised in Austin was anything other than safe family fun. We represent families in Austin who are living through that nightmare. We are The Manginello Law Firm—Attorney911. For over twenty-five years, Ralph Manginello has stood in trauma bays and hospital rooms, watching surgeons explain to parents what happens when a growth plate is destroyed or a cervical spine is crushed.

When your child is injured at an Austin trampoline park, the clock starts running immediately. Surveillance footage at parks like Urban Air in Cedar Park or Sky Zone in South Austin is often overwritten in as little as seven to thirty days. Incident reports are frequently "finalized" on corporate servers with revisions that sanitize the park’s negligence. Our team, which includes an attorney who used to defend these exact recreational businesses, knows the…

"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 are the words of Kati Hill, a mother who watched her three-year-old son, Colton, suffer a broken femur at a trampoline park. To Kati, and to thousands of parents across Texas, that sound is the end of an era of innocence. It is the sound of a family’s life changing in two seconds of airborne energy. Kati told ABC News what every parent we represent in Anderson Mill (historical) eventually says: "We had no idea. We would have never put our baby boy on a trampoline if we had known." At Attorney911, led by Ralph Manginello with over 25 years of catastrophic injury experience, we have heard that scream through the files of our clients. We have stood in the trauma bays of Level 1 pediatric centers like Dell Children’s Medical Center in Austin, serving families from Anderson Mill (historical), watching specialists explain what happens when a growth plate is destroyed at age nine. We know that a trampoline injury in Anderson Mill (historical) is almost never an "accident." It is the predictable, mathematical output of a business decision made by a corporation that prioritized throughput over participant safety. Whether your child was injured at an Urban Air, a Sky Zone, an Altitude, or on a neighbor’s backyard Jumpking or Skywalker trampoline, you are likely being told that the waiver…

At the Sky Zone in Cedar Park or the Urban Air serving families near Anderson Mill, a child comes off a court on a stretcher. His parents had signed the waiver at the kiosk twenty minutes earlier. They believed the "Toddler Time" advertising. They believed the teenagers in the neon shirts were watching the court. They believed the environment was designed for their five-year-old’s safety. Then, the double-bounce happened. In two seconds, their child was airborne, then he wasn't. We have seen this scene at the trauma-bay bedside of Dell Children’s Medical Center more times than we care to count. One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park. If your life has been altered by a trampoline accident in Anderson Mill, you are likely feeling a combination of terror, anger, and a crushing sense of guilt. You tell yourself you shouldn't have let them go. You tell yourself you should have read every word of that twenty-page waiver on the iPad at the front desk. We are here to tell you that what happened to your child in Anderson Mill wasn't an accident—it was the predictable output of a system. The American Academy of Pediatrics (AAP) has been warning since 1999 that trampolines do not belong in a recreational setting for children. ASTM F2970 was written by the trampoline park industry itself to establish a safety floor. The park in the Anderson Mill area likely operated below that floor to hit…

"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 was shared 240,000 times. We have read it. So has every parent of every child who has been hurt at a trampoline park or on a backyard trampoline since. In Wylie and throughout San Saba County, that scream is the sound of a family's life changing in two seconds. You were at a birthday party in Austin or San Antonio, or perhaps you were watching from the porch in Wylie as the neighbors' kids jumped. Then the double-bounce happened. Whether the injury occurred at a high-throughput commercial facility like Urban Air or Sky Zone, or on a mass-market backyard trampoline from Jumpking or Skywalker, the aftermath is the same: the ambulance ride, the trauma bay, and the insurance adjuster calling 48 hours later to "check in." We are the attorneys of Attorney911. We represent families in Wylie who are facing the most difficult chapters of their lives. Our founder, Ralph Manginello, brings over 25 years of courtroom experience to these cases, including litigation against Fortune 500 giants like BP.

On a hot Saturday afternoon in the Town of Trent, the atmosphere inside a packed trampoline park can shift from laughter to a life-altering emergency in less than two seconds. We have seen this transition too many times. A three-year-old boy named Colton was jumping during a "Toddler Time" session in a Texas park when a larger child landed on the same trampoline bed. His mother, Kaitlin "Kati" Hill, later told ABC News that the sound her son’s femur made when it snapped was followed by "the worst scream that you could ever have heard from a child." Colton spent the next several months in a body cast. His mother’s public warning has been shared hundreds of thousands of times because, as she put it, "We had no idea." At the Manginello Law Firm, we know that families in the Town of Trent and across Taylor County visit these facilities because they believe the marketing. They believe the "Safety First" signs and the "certified" court monitors. But we understand the architecture of the industry differently. We know that roughly 1.6% of all pediatric emergency department trauma visits in the United States are now trampoline-related, according to the American Journal of Roentgenology (AJR 2024). We know that behind the neon lights of national chains like Urban Air, Sky Zone, and Altitude, there is a profit-driven system that routinely prioritizes throughput over the safety of your child. If your family is currently at a hospital bedside in an Abilene or San Angelo…
