One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park in Grand Prairie. At the Big Air Trampoline Park or the nearby Urban Air and Altitude locations serving Grand Prairie families, a child can go from a Saturday afternoon birthday party to a pediatric trauma bay in less than three seconds. Their parents signed a waiver at a flickering kiosk twenty minutes earlier, usually under the pressure of a long line and excited kids. Now, as they sit in the waiting room at Children’s Medical Center Dallas or Cook Children’s in Fort Worth, they are told their child has a Salter-Harris growth plate fracture or, worse, a cervical spine injury that the ER staff is screening for SCIWORA—spinal cord injury without radiographic abnormality. When that happens, the park's management doesn't usually call 911. They hand you a clipboard. They tell you it was a "freak accident." They remind you that you "assumed the risk." They are wrong. At Attorney911, we have spent more than 25 years making corporate defendants pay for the "business decisions" they disguise as accidents. Our founder, Ralph Manginello, has taken on Fortune 500 giants like BP in the wake…

One bounce. One bad landing. One broken neck. That is all it takes for a Saturday afternoon in the City of Glenn Heights to turn into a lifetime of medical monitoring and trauma-bay recovery. Families across the City of Glenn Heights often visit the massive adventure parks that line the I-35E corridor, from the Urban Air in Waxahachie or Mansfield to the Altitude in Cedar Hill. You sign a waiver because the line is long and your children are excited. You hand over your credit card and receive a wristband. You believe that because the facility is open to the public, it has been inspected by the state or follows professional safety protocols. The truth is much darker. In Texas, there is no statewide law regulating trampoline park safety. There are no mandatory state inspections of trampoline decks, and there is no requirement for the park to report injuries to the government. At parks across the City of Glenn Heights and the DFW Metroplex, the person watching your child is often a 17-year-old making near-minimum wage with fewer than four hours of training. When your child is launched into the air by a "double-bounce" or sinks to the bottom of…

One second your child was jumping on a trampoline in the City of Garland. The next, their legs crumpled, and they let out a scream that no parent should ever have to hear. It’s a moment of pure terror that shifts from a Saturday afternoon birthday party to a life-changing medical emergency in the time it takes to land a single bounce. If you are reading this from a hospital bedside at Children’s Medical Center Dallas or while your child recovers in a body cast at your City of Garland home, we have one thing to say to you first: This is not your fault. For over 25 years, our managing partner Ralph Manginello has stood with families facing the aftermath of catastrophic injuries. We have seen how insurance companies use the paperwork you signed at a kiosk as a weapon to make you believe you have no rights.

From our Texas offices in Houston, Austin, and Beaumont, we represent City of Garland families and victims nationwide who have been harmed by a system…

"Sus pies tocaron la colchoneta y, casi al instante, sus rodillas se doblaron y soltó el peor grito que jamás se haya escuchado de un niño". Esa es Kaitlin "Kati" Hill, una madre cuyo hijo de tres años, Colton, sufrió una fractura de fémur y pasó semanas con un yeso de cuerpo completo tras una visita a un parque de trampolines. Como le dijo a ABC News: "No teníamos idea. Nunca habríamos puesto a nuestro bebé en un trampolín si lo hubiéramos sabido". En la Ciudad de Ferris, las familias se encuentran a un corto trayecto en auto por la I-45 del grupo más denso de parques de trampolines del país. A menos de treinta minutos de un vecindario tranquilo en la Ciudad de Ferris, sus hijos pueden estar dentro de un Urban Air en Waxahachie, un Altitude en Cedar Hill o un Sky Zone en Irving. Estas instalaciones se promocionan como centros de "diversión familiar segura", pero la realidad detrás de las luces brillantes y la música fuerte es un modelo de negocio que escala el riesgo a un nivel industrial. Somos Attorney911. Nuestro socio director, Ralph Manginello, ha pasado más de 25 años exigiendo responsabilidades a demandados corporativos…

One bounce. One bad landing. One life changed forever. For families in City of Farmers Branch, a Saturday afternoon at a trampoline park is marketed as a high-velocity playground for birthday parties and "glow nights." But the reality inside facilities like Sky Zone Irving or Urban Air North Dallas is often far more dangerous than the bright lights and loud music suggest. At Attorney911, we call the sound that follows a trampoline accident in City of Farmers Branch "the worst scream you could ever hear from a child." That is how Kaitlin "Kati" Hill described the moment her three-year-old son’s femur snapped during a session marketed for toddlers. Colton spent months in a body cast because a bigger child landed on his trampoline bed. Kati’s warning was shared over 240,000 times because most parents in City of Farmers Branch have no idea that these facilities are built on a foundation of systemic negligence and calculated risk. We don't look at a child’s broken leg as a "freak accident." We see a business decision. When a park in City of Farmers Branch operates at half the required attendant ratio during a weekend rush to protect their profit margins, the injuries that…

"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 "Kati" Hill, a mother whose three-year-old son, Colton, suffered a broken femur during a "Toddler Time" session at a trampoline park. Colton spent months in a body cast. Kati shared her story on social media, and more than 240,000 parents shared it with her, all repeating the same heartbreaking refrain: "We had no idea." If you’re reading this at 11 PM from a hospital waiting room at Children’s Medical Center Dallas or another Level 1 pediatric trauma center serving the City of Duncanville, you are now part of a group no parent ever wants to join. Your child was at a birthday party, an open-jump session, or simply playing in a neighbor’s backyard near the Wheatland Road corridor or along US-67. Then, in two seconds, everything changed. We’re here to tell you that what happened to your child wasn't a freak accident. It was the predictable result of an industry that, for decades, has put profit margins ahead of pediatric safety.

The Parent’s Guide to Trampoline Park Injuries in City of DeSoto, 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."

Colton didn't just fall; he suffered a broken femur that required him to be placed in a body cast for months.

At Attorney911, we have spent 25+ years representing families who had "no idea" how dangerous these facilities actually are.

"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 Kaitlin "Kati" Hill, telling ABC News what happened when her three-year-old son, Colton, broke his femur at a trampoline park during a "Toddler Time" session. Her warning to other parents was shared 240,000 times. We read it. We hear that scream in almost every initial phone call we take from families in the City of Coppell and across North Texas. What happened to Colton—and what may have happened to your child at an indoor jump center near the City of Coppell—was not an "accident." It was the predictable, mathematically certain output of a business model that prioritizes throughput and profit margin over pediatric safety. At Attorney911, we don't treat these as simple slip-and-falls. We treat them as corporate accountability cases. Whether your injury occurred at the Urban Air in Southlake, the Sky Zone in Irving, or on a backyard Jumpking in a City of Coppell neighborhood, you are now facing an insurance machine designed to silence you with a signature you gave at a kiosk.

In Harris County, Texas, a jury awarded $11.485 million—including $6 million in punitive damages—against the operator of Cosmic Jump after a 16-year-old fell through a torn trampoline slide onto concrete and suffered a traumatic brain injury.

"Sus pies tocaron la lona, y casi al instante sus rodillas cedieron, y simplemente soltó el peor grito que jamás podrías haber escuchado de un niño". Esa es Kaitlin "Kati" Hill, una madre que vio a su hijo de tres años, Colton, fracturarse el fémur en un parque de trampolines. Su historia, que ha sido compartida más de 240,000 veces en las redes sociales, resuena en cada padre que ha estado en una sala de traumatología en el condado de Dallas. En el bufete de abogados Manginello, nosotros también hemos escuchado ese grito. Hemos estado al lado de la cama de niños en Cockrell Hill que fueron a una fiesta de cumpleaños en un Urban Air o Sky Zone cercano y regresaron a casa con un yeso de cuerpo completo. Si está leyendo esto a las 11 p. m. desde la sala de espera de un hospital en el Children’s Medical Center Dallas o en otro centro de traumatología de DFW, hay tres cosas que debe saber de inmediato. Primero, lo que le sucedió a su hijo no fue un "accidente fortuito"; fue el resultado predecible de una industria multimillonaria que prioriza el margen de beneficio sobre la supervisión. Segundo,…
