"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." These are the words of Kaitlin "Kati" Hill, a mother who watched her three-year-old son, Colton, suffer a broken femur at a trampoline park. Her warning, shared a quarter of a million times on social media, ended with a haunting admission: "We had no idea." If you are reading this from a hospital waiting room at Dell Children's Medical Center or a quiet living room in the Village of Briarcliff, you likely find yourself in that same position. You thought you were giving your child an afternoon of "safe family fun" at an Urban Air in Bee Cave or the Sky Zone in Cedar Park. You signed the required electronic document on a kiosk, assuming it was a standard sign-in sheet. Then, in one second, everything changed. One bounce. One bad landing. One life-altering injury. We are Attorney911, and we have spent over 25 years representing families in the Village of Briarcliff and across Texas who have been devastated by catastrophic injuries. We know that what happened to your child wasn't…

At the Altitude Trampoline Park on South Interstate 35 in Round Rock, or the nearby Sky Zone in Cedar Park and Urban Air Adventure Parks serving Williamson County, a Saturday afternoon can change a family’s narrative in less than two seconds. For most parents in Round Rock, these facilities are seen as the "Sports Capital of Texas" equivalent of indoor recreation—a safe place for birthday parties, off-season conditioning for youth football, or a summer escape from the 100-degree Central Texas heat. But when your child hits the mat and you hear what Texas mother Kati Hill described to ABC News as "the worst scream that you could ever have heard from a child," the illusion of safety vanishes. You are no longer a parent at a birthday party; you are a parent at the bedside in a trauma bay at Dell Children’s Medical Center, watching a surgeon explain that your eight-year-old has sustained a Salter-Harris Type II fracture—a growth plate injury that may not grow straight for the next decade. At Attorney911, we believe you deserve to know the truth that the kiosk in the lobby won't tell you: A trampoline injury is never an accident. It is a business…

In Mustang Ridge, families often travel along SH-130 or US-183 toward Austin or San Marcos seeking "safe family fun" at one of the region’s massive trampoline and adventure parks. You take your children to a birthday party at an Urban Air or an afternoon jump at Altitude, trusting that the teenage staff and the corporate branding provide a safe environment for your child to burn off energy. But in a single second, the laughter stops. A double-bounce launch, a harness that wasn't clipped correctly, or an under-filled foam pit converts a Saturday afternoon into a life-altering medical emergency. At Attorney911, led by managing partner Ralph Manginello with over 25 years of courtroom experience, we’ve seen the aftermath of these business decisions. We’ve stood in trauma bays with parents from Mustang Ridge while surgeons explain what happens when a growth plate is destroyed at age nine. We’ve written the demand letters that make insurance adjusters realize they aren't dealing with a generalist firm, but with a team that knows ASTM F2970 and the physics of trampoline injuries better than the park’s own risk managers. If your child was injured at a trampoline park or on a backyard trampoline in Mustang Ridge,…

The Complete Guide to Trampoline Injury Law in Elgin: Protecting Your Family’s Rights "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 "Kati" Hill, a mother whose three-year-old son Colton suffered a broken femur and was forced into a body cast after an afternoon at a trampoline park. As she told ABC News, "We had no idea. We would have never put our baby boy on a trampoline if we had known." Kati Hill’s warning post was shared 240,000 times because it struck a chord with every parent who has ever signed an English-only waiver at a kiosk while their children pulled at their sleeves to go jump. At Attorney911, we know that scream. We represent families in Elgin and throughout Texas who are living through the nightmare Kati Hill described.

Kaitlin Hill, a mother known as Kati to her friends, took her three-year-old son Colton to a trampoline park during a session marketed for the youngest jumpers. Like many families in West Lake Hills, she believed that a facility advertising "Toddler Time" had been engineered for the safety of children his size. But a larger child—older and significantly heavier—rebounded on the same trampoline mat at the wrong instant. The energy transfer from the heavier jumper launched Colton with a force his small frame was never meant to decelerate. His femur, the strongest bone in the human body, snapped. We have read Kati’s description of that moment many times; she calls it the worst scream you could ever hear from a child. Colton spent months in a body cast. When Kati posted her warning to other parents, it was shared a quarter-million times. Her conclusion was simple and haunting: "We had no idea." At Attorney911, we share this story because we represent families in West Lake Hills who are currently living that same nightmare. We represent parents sitting in the waiting rooms of Dell Children’s Medical Center, watching as surgeons explain what a Salter-Harris growth plate fracture means for their child’s…

Her warning, shared hundreds of thousands of times, echoes the experience of thousands of parents who enter facilities like the Altitude Trampoline Park on the I-35 corridor in Round Rock or the Sky Zone in Cedar Park.
