"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." When Kati Hill told ABC News about the day her three-year-old son Colton broke his femur at a trampoline park, she was describing a nightmare that hundreds of families in the City of Mesquite and surrounding Dallas County face every year. Colton wasn't doing backflips or acting recklessly. He was a toddler at a facility that marketed "Toddler Time." His parents had signed the waiver at the kiosk twenty minutes earlier. They, like so many parents in City of Mesquite, had no idea that their child was walking onto a court where the physics were engineered for injury and the safety protocols were treated as optional. At Attorney911, led by Ralph Manginello with over 25 years of experience in catastrophic injury litigation, we have seen exactly how these facilities operate. From our offices in Houston, Austin, and Beaumont, we represent families across Texas—including City of Mesquite—who are tired of being told that their child’s life-altering injury was just a "freak accident" or an "inherent risk." We know better. What happened to…

One bounce. One bad landing. One broken neck. That is the timeline of a catastrophic injury at a trampoline park in Lewisville, and for many families, it is a nightmare that begins in the seconds it takes for a court monitor to check their phone. At the Launch Family Entertainment center off the I-35E frontage road in Lewisville, or the nearby Urban Air and Sky Zone locations serving Denton County, thousands of children are airborne every weekend. They are jumping at facilities that market "safe family fun" while operating under a business model that prioritizes throughput and margin over the survival of your child’s growth plates. When your child comes off a court on a stretcher at Medical City Lewisville, and the manager hands you a clipboard instead of calling 911, you are seeing the first layer of a corporate defense system designed to isolate the park from the consequences of its own decisions. We are Attorney911. With over 25 years of experience fighting Fortune 500 corporations, Managing Partner Ralph Manginello has built a firm that doesn’t just handle personal injury cases—we dismantle corporate liability shields. We know that a trampoline injury in Lewisville is never an "accident." It is…

"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 Kati Hill, describing the moment a trampoline park broke her three-year-old son’s femur. It is a scream that echoes in the minds of parents across the City of Lancaster and throughout Dallas County every time a weekend birthday party at a local adventure center ends in an ambulance ride. We have heard that story. We have stood in the trauma bays at Children’s Medical Center Dallas. And we have seen the stack of medical bills and the "friendly" phone calls from insurance adjusters that follow. If your child was injured at a trampoline park serving the City of Lancaster or on a defective backyard trampoline in your neighborhood, you are likely feeling a combination of terror, exhaustion, and guilt. You signed the waiver because the line was long and the kiosk was fast. You let your child jump because you wanted them to have fun. You trusted that the park followed the rules. None of this is your fault. A trampoline injury is never just an accident; it is…

"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, describing the moment a trampoline park shattered her three-year-old son Colton’s femur. Her warning was shared 240,000 times because it resonates with the terror every parent feels when a Saturday afternoon at a park in Irving turns into a nightmare in a trauma bay. We have stood at those bedsides. We have seen the body casts and the wheelchairs on the porch. And we have heard the phrase that echoes through every one of our intake calls: "We had no idea." If your child was injured at a trampoline park in Irving—whether at the Sky Zone in the Irving Mall, the Ground Control in Las Colinas, or an Urban Air in the surrounding mid-cities—the most important thing we can tell you is this: it was not an accident. It was the predictable output of a system designed to prioritize profit margins over your child’s safety. At Attorney911, led by Ralph Manginello with over 25 years of courtroom experience, we don’t treat these as "freak accidents." 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." That was Kaitlin Hill telling ABC News about the moment her three-year-old son’s life was upended by a broken femur at a trampoline park. It is a scream we have heard echoed in the stories of families across Texas. At The Manginello Law Firm, also known as Attorney911, we know that for parents in Hutchins and across Dallas County, that sound is the beginning of a nightmare. You take your child to a place like Sky Zone, Urban Air, or Altitude expecting a safe afternoon of family fun near the I-45 corridor. You sign a waiver because the line is long and the staff is rushing you. You trust the "court monitors" to keep the big kids away from the little ones. Then the physics of a double-bounce takes over. Within seconds, your child is airborne, then screaming on the mat while an eighteen-year-old attendant looks on, unsure of whether to call 911 because they weren't trained for this. We are not just another personal injury firm in Dallas. We 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 is how Kaitlin "Kati" Hill described the moment her three-year-old son Colton’s femur was shattered at a trampoline park. Her warning, shared a quarter of a million times on social media, echoed the same five words we hear from families in City of Grapevine every month: "We had no idea." At the Urban Air Adventure Park or the Altitude Trampoline Park near City of Grapevine, the courts look like a supervised, safe environment for a birthday party or a Saturday afternoon. But behind the neon lights is a system designed to maximize throughput and minimize legal accountability. We represent families in City of Grapevine who have lived the nightmare Kati Hill described. We know that when a child is launched by a 200-pound adult in a double-bounce or falls thirty feet from a climbing wall because a harness wasn't attached, it isn't an accident. It’s a business decision. We have spent over 25 years making corporate defendants pay for prioritizing margin over human life. Ralph Manginello brings federal court experience…

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…

Fam. Code § 153.073 Signer-Authority Attacks; Serving City of Glenn Heights with 24/7 Legal Emergency Support, Hablamos Español, Free Consultations, and No Fee Unless We Win at 1-888-ATTY-911

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…
