One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park serving City of Lakeway. In the trauma bays of Level 1 pediatric centers across Travis County, the story is often the same. A parent signed a waiver at a kiosk, handed their child a wristband, and within twenty minutes, their world changed. At The Manginello Law Firm, we represent families who have experienced the "worst scream you could ever hear from a child," as Kati Hill described the moment her three-year-old’s femur snapped during a Toddler Time session. We are Attorney911, and we have spent over 25 years making corporate defendants pay for putting margin ahead of safety. If your child was injured at a facility like the Urban Air near Bee Cave or a backyard trampoline in an affluent City of Lakeway neighborhood, you might think the waiver you signed ends your case. It doesn't. We know because our team includes attorney Lupe Peña, who used to sit on the other side of the table—defending insurance companies and the very recreational businesses we now sue. He knows exactly which waiver clauses are airtight and which ones are full of holes under 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."

At the Sky Zone in Cedar Park or the Urban Air serving families from the City of Jonestown, the Saturday afternoon rush follows a predictable rhythm. The music is loud, the air conditioning is humming against the central Texas heat, and hundreds of children are airborne. For the parents driving down RM 1431 from the City of Jonestown, the visit is a well-deserved break—a "safe" place for kids to burn energy. But beneath the neon lights and the "Toddler Time" branding, a systemic risk is often ignored until the moment of impact. The mechanism that changes a family’s life in the City of Jonestown doesn't take minutes; it takes milliseconds. A child pushes off a trampoline bed just as an adult lands on the same mat. In the physics of the trampoline industry, this is known as a double-bounce energy transfer. Because the trampoline bed stores and releases elastic potential energy, the heavier jumper acts as a catapult. At a 3:1 weight ratio, a child from the City of Jonestown can be launched with up to four times their normal launch force. In one second, the child is mid-air; in the next, they land with a force their developing musculoskeletal…

"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 Kaitlin "Kati" Hill, a mother who watched her three-year-old son, Colton, suffer a broken femur in a body cast after a visit to a trampoline park. As Kati told ABC News, she had no idea. She would have never put her baby boy on a trampoline if she had known the truth. If you are reading this in City of Elgin, perhaps you are in a similar position. You are sitting at a hospital bedside at a Level 1 trauma center like Dell Children's Medical Center or University Hospital, watching a surgeon explain what happens when a growth plate is destroyed at age nine. You are looking at a stack of medical bills that already exceeds your HSA, and you are remembering the iPad kiosk at the front desk where you were told to "sign quickly so the kids can jump." What happened to your child in City of Elgin wasn't a freak accident. It was the predictable output of a system. At Attorney911, we believe…

"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.

"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…

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…
