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…

Seeking Justice After a Trampoline Injury in the City of Sunset Valley "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 during what was supposed to be a safe "Toddler Time" session at a park. Her warning, shared a quarter of a million times, ends with a sentiment we hear from families in the City of Sunset Valley every single week: "We had no idea." If your child was injured at a trampoline park near the City of Sunset Valley, or if you were hurt on a defective backyard trampoline in your own neighborhood, you are likely standing where Kati Hill stood. You are at the bedside in a trauma bay—perhaps at Dell Children’s Medical Center—watching your child deal with a Salter-Harris growth plate fracture or a traumatic brain injury. You are probably replaying the moment you signed that electronic waiver on the iPad kiosk, wondering if you signed away your family's future. We are Attorney911. Our firm is led…

"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. Like many parents in the City of Rollingwood, she had no idea that a Saturday afternoon outing could end in a body cast. At the Manginello Law Firm, we hear variations of this story every week. We represent the families who were told it was a "freak accident" but later discovered it was the predictable result of a business decision. Whether your child was injured at an Urban Air in South Austin or Bee Cave, an Altitude in Travis County, or on a backyard Jumpking or Skywalker trampoline in the City of Rollingwood, the reality is the same: the system was built to prioritize margin over your child’s safety.

"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 suffer a broken femur at a trampoline park. Her warning, shared hundreds of thousands of times across social media, is a nightmare that stays with every parent in Pflugerville who has ever stood at an observation rail watching their child go airborne. If you are reading this from a hospital bedside at Dell Children’s Medical Center or while waiting for an orthopedic specialist in Round Rock or Pflugerville, we know the weight you’re carrying. You signed a digital waiver on a kiosk in a crowded lobby. You were told it was "safe family fun." You were told that trampoline parks are a great way for kids to burn off energy.

One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park. For many families in Manor, a trip to an indoor jump center across the Travis County line or a weekend afternoon on a backyard trampoline on a lot off Highway 290 feels like harmless fun. You see the bright colors, you hear the music, and you see the laughter. But as trial attorneys who have spent more than 25 years fighting for catastrophic injury victims, we see something else. We see the physics of 1,000 Newtons of force hitting a child’s developing growth plate. We see the 5-layer corporate structure designed to hide the money we know is upstream. And we see the parent at the Dell Children’s Medical Center bedside, holding a signed waiver in one hand and their child’s hand in the other, thinking they have no rights. We are here to tell you that what happened to your child in Manor was not a "freak accident." It was the predictable output of a system that puts margin ahead of pediatric safety. Whether you were at a Sky Zone, an Urban Air, an Altitude, or an independent park near Manor, the…

One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park serving City of Lakeway.

A parent signed a waiver at a kiosk, handed their child a wristband, and within twenty minutes, their world changed.

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 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…

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…
