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…

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…

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…

"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.

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.

"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.

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…

"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 was how Kaitlin "Kati" Hill described the second her three-year-old son Colton’s life changed forever. Colton wasn't doing anything reckless. He was participating in a "Toddler Time" session designed for children his age at a commercial trampoline park. But a larger child landed on the same trampoline bed, and the resulting energy transfer snapped Colton’s femur—the strongest bone in the human body. He spent the following months in a body cast, and his family joined the thousands of others across the United States who have realized, too late, that the marketing of "safe family fun" in places like Town of Lawn is often a sanitized mask for an industry operating under a systemic architecture of negligence. If your child was injured at a trampoline park serving Town of Lawn, or if a backyard trampoline accident has left your family in a state of medical and financial crisis, we recognize the terror of the moment. We are Attorney911—The Manginello Law Firm. For over 25 years, our founder Ralph Manginello has stood…
