The Parent's Complete Guide to Trampoline Park Injuries in City of Killeen One Bounce. One Landing. One Life Changed. "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 whose three-year-old son Colton suffered a broken femur and required a body cast after a trampoline incident. Her story, shared over 240,000 times, is the nightmare every parent in City of Killeen fears when they walk into a facility like Urban Air or Xtreme Jump. At Attorney911, we know that what happened to Colton Hill isn't an isolated accident. It is a predictable outcome of a multibillion-dollar industry that often prioritizes throughput and profit margins over the musculoskeletal safety of developing children. We are led by managing partner Ralph Manginello, who brings over 25 years of experience to every catastrophic injury case. Since 1998, our firm has held Fortune 500 companies accountable—from the BP Texas City refinery litigation to our current $10 million lawsuit against the University of Houston regarding rhabdomyolysis and acute kidney failure. If your child was injured at a trampoline park in City of Killeen, you are likely facing an uphill battle against a complex corporate shield. You may have been told that the waiver you signed at a kiosk ends your case. It doesn't. You need an attorney who can quote ASTM F2970 from memory and who understands…

City of Harker Heights Trampoline Park Injury & Pediatric Catastrophic Accident Attorneys Attorney911 of Houston TX: 25+ Years Defeating Sky Zone, Urban Air, and Altitude Waivers with Ralph Manginello and Former Recreational-Business Defense Insider Lupe Peña, $15.6M Damion Collins & $11.485M Cosmic Jump Harris County Verdict Mastery, ASTM F2970 / ASTM F381 / AAP / EN ISO 23659:2022 Standards Compliance Experts for Pediatric TBI, SCIWORA Spinal Cord, Salter-Harris Growth Plate, and Rhabdomyolysis Litigation, Defeating Unconscionable Contracts via Delfingen Bilingual Doctrine and Texas Family Code 153.073 Signer-Authority Attacks for City of Harker Heights Families Impacted by Sky Zone, Urban Air, DEFY, and Backyard Jumpking Accidents, Hablamos Español, No Fee Unless We Win, Call 1-888-ATTY-911

"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 warning to other parents was shared 240,000 times after her three-year-old son, Colton, suffered a broken femur at a trampoline park. As Colton's orthopedic surgeon later explained to her, the repetitive, high-velocity bouncing of a trampoline was never intended for the developing bones of a toddler. Kati’s words—"We had no idea"—are the same words we hear from families in Harker Heights and across Central Texas every time a fun Saturday afternoon at a place like Urban Air or Xtreme Jump turns into a nightmare of stretchers, surgery, and lifelong medical monitoring. At Attorney911, we have spent more than 25 years standing in the gap between families and the corporate conglomerates that treat child safety as an adjustable line item on a profit margin. Led by Ralph Manginello, our firm brings federal court experience and a history of taking on Fortune 500 giants like BP to the specialized field of trampoline injury litigation. We are not a volume personal injury firm that handles "slips and falls." We are a catastrophic injury practice that understands the physics of a double-bounce launching a child with 4x the force of gravity, the medical complexity of a Salter-Harris growth plate fracture, and the legal strategies needed to dismantle a "kiosk waiver" designed to trick you into thinking you…

"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. Her warning, shared over 240,000 times on social media, included five words that haunt every parent in the City of Belton whose family has been touched by this industry: "We had no idea." At Attorney911, led by founding partner Ralph Manginello with over 25 years of trial experience, we see the aftermath of that "no idea" every day. Since 1998, we have fought for families in the City of Belton and across Texas who were told their child’s injury was a "freak accident" or an "inherent risk." We know better. A shattered tibia on a Saturday afternoon at a park near I-35 or a traumatic brain injury in a Belton backyard is rarely an accident. It is the predictable output of a system that puts corporate margins ahead of pediatric safety. We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure—the same catastrophic muscle and organ breakdown we see in children who jump for ninety minutes in a heated indoor facility in the City of Belton and arrive at an emergency room two days later in renal crisis. Our team includes associate attorney Lupe Peña, who used to defend insurance companies…

A Central Texas mother's memory of a Saturday afternoon in the City of Bartlett doesn't begin with the drive down State Highway 95 or the excitement of a birthday party in a nearby Round Rock or Cedar Park attraction. It begins with a sound. Kaitlin "Kati" Hill described it to ABC News as "the worst scream that you could ever have heard from a child." Her three-year-old son, Colton, was jumping in a "Toddler Time" session designed for small children. A larger, older jumper landed on the same mat. The transfer of energy—a physics-driven event known as a double-bounce—snapped Colton’s femur. We have seen this story repeat across the City of Bartlett and the surrounding Williamson County corridor. We represent the families who were told "it's just a freak accident." We represent the parents who signed a digital waiver on an iPad and now believe they have no rights. We are here to tell you that what happened to your child wasn't an accident; it was the predictable output of a business model that prioritizes throughput and margin over the safety of the children of City of Bartlett. At Attorney911, led by Ralph Manginello with over 25 years of catastrophic injury experience, we don't accept the park's excuses. Our firm includes attorneys like Lupe Peña, who used to sit on the other side of the table defending recreational businesses. He knows the playbook they use to deny your claim in City of Bartlett, and he knows how to dismantle it.…

If you are reading this in a waiting room near Bartlett or while sitting at your child’s bedside at Baylor Scott & White McLane Children’s Medical Center in Temple, you’ve likely just lived through every parent’s worst nightmare. Your child was airborne at a trampoline park—perhaps the Urban Air in Killeen or the massive 60,000 square foot Xtreme Jump in Temple—and in one-tenth of a second, their life changed. We have spent more than 25 years representing families who have seen their world shattered by catastrophic injuries. We have stood where you are standing. We have looked at the x-rays of a shattered pediatric femur and listened to orthopedic surgeons explain that a growth plate injury at age eight means a decade of surgeries to come. We know that right now, you aren't just dealing with a "broken bone." You are dealing with mounting medical bills, the fear of permanent disability, and a predatory insurance adjuster who is already calling you to offer a "friendly settlement" that wouldn't cover the cost of your child’s first follow-up surgery. At Attorney911, led by Ralph Manginello since 1998, we don't handle trampoline cases like a typical neighborhood law firm. We treat them like the corporate accountability battles they are. We’ve gone toe-to-toe with Fortune 500 giants like BP after the Texas City refinery explosion; we are not intimidated by the private equity sponsors like Palladium Equity or Seidler Equity that back the parent companies of Sky Zone, Urban Air, and DEFY. We represent…

In the heat of a Texas Saturday afternoon, thousands of families across Houston, Dallas-Fort Worth, Austin, and San Antonio walk through the doors of facilities like Sky Zone, Urban Air, and Altitude. They are seeking an hour of active fun, often celebrating a birthday or a school milestone. But for many of these families, the visit ends not with cake and goody bags, but with the sound that Kati Hill, a mother of a three-year-old boy named Colton, still hears in her nightmares. As she told ABC News after her son’s femur was shattered at a trampoline park, it was "the worst scream that you could ever have heard from a child." At Attorney911, we have spent more than 25 years standing at the bedsides of families facing these exact moments. We know the terror of watching a surgeon explain what a Salter-Harris growth plate fracture means for a seven-year-old’s ability to walk properly in a decade. We know the frustration of the "friendly" phone call from an insurance adjuster who claims the waiver you signed on a park iPad ends your case before it begins. Most of all, we know the truth that the trampoline park industry spends millions to hide: these injuries are not "accidents." They are the predictable output of business decisions that put profit margins ahead of child safety. If your family is dealing with the aftermath of a trampoline injury in Texas, you are not just a client to us. As our client Chad Harris…

The Complete Guide to Trampoline Injury Law in the United States The Heart of the Matter: Why We Wrote This Guide "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 what Kaitlin "Kati" Hill told ABC News after her three-year-old son, Colton, suffered a broken femur during a "Toddler Time" session at a trampoline park. Her Facebook post, shared over 240,000 times, ended with five words that haunt every parent who has ever signed a digital waiver at a kiosk: "We had no idea." We hear that phrase at our firm constantly. Families across the United States walk into these facilities believing that "industry standards" and "certified monitors" mean their children are safe. They aren't. Approximately 1.6% of all pediatric emergency department trauma visits in the United States are now related to trampolines. Whether it is a commercial park or a backyard trampoline in a neighborhood anywhere in the United States, the physics of a high-energy rebound do not negotiate with developing bones. Our lead attorney, Ralph Manginello, has spent over 25 years handling catastrophic injury cases in both state and federal courts. We are not just another personal injury firm; we are a team that has gone toe-to-toe with Fortune 500 giants like BP, Walmart, and Amazon. We understand that a trampoline injury in the United States is rarely a "freak accident." It is almost always the…

"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 during a "Toddler Time" session at a trampoline park. Her warning, shared hundreds of thousands of times across North America, echoes a terrifying reality that we see in our practice every day: these facilities are not the safe havens for family fun they claim to be. They are industrial-scale energy-transfer environments where a single business decision—cutting staff, skipping maintenance, or ignoring safety standards—can change a child's life forever. If your family is currently sitting in a pediatric trauma ward in North America, or if you are at home watching your child struggle with a body cast or a developing brain injury, you likely feel a crushing weight of guilt and uncertainty. You signed a waiver. You thought it was a freak accident. You were told the park isn't responsible. We are here to tell you that none of that is true. What happened to your child wasn't an accident; it was the predictable output of a system. At Attorney911, led by Ralph Manginello with over 25 years of experience in catastrophic injury and federal court litigation, we have spent decades making corporate defendants pay for putting margin ahead of safety. Whether the defendant is a multinational oil company or a private-equity-backed trampoline chain like…

"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 what happened the day a trampoline park broke her son’s femur. Her warning post was shared 240,000 times. We read it. So did every parent of every child who has been hurt at a trampoline park in Earth since. At Attorney911, we know that scream. We represent the families who have to hear it. We represent the parent standing at a hospital bedside in Earth watching a surgeon explain what happens when a growth plate is destroyed at age nine. We have spent more than 25 years fighting for families facing catastrophic, life-altering injuries. Our managing partner, Ralph Manginello, has been holding corporate defendants accountable since 1998, with admission to federal courts and a track record of multi-million dollar results. If your child was injured at a trampoline park in Earth, the first thing you need to hear is this: this is not your fault. 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. The park knew the safety standards. The park knew the risks. The park chose margin over your child’s safety. What happened to your family wasn't an accident. It was the predictable output of a system designed to maximize…

Ley de Exposición Tóxica y Lesiones Industriales en Crystal City: Haciendo que las corporaciones rindan cuentas a los trabajadores del condado de Zavala Usted no lo sabía. Durante veinte años, treinta años, tal vez más, fue a trabajar a los campos que rodean Crystal City, cumplió con su labor en las plantas de procesamiento o trabajó turnos en las plataformas petroleras en toda la formación Eagle Ford Shale. Regresaba a casa con su familia en Crystal City, se quitaba el polvo de la piel y nunca cuestionó el aire que respiraba ni los productos químicos que manipulaba. Nadie en la oficina administrativa le dijo que el fino polvo blanco de su ropa o los vapores de olor dulce en la casa de bombas algún día intentarían matarlo. Ahora, un médico en Uvalde o San Antonio le ha dado un diagnóstico que hace que esas décadas de arduo trabajo se sientan como una traición. Ya sea mesotelioma, leucemia mieloide aguda o los temblores de la enfermedad de Parkinson, hay una palabra para lo que le sucedió. No fue mala suerte ni simplemente la vejez. Fue exposición. Y hoy, usted tiene derechos que estamos listos para hacer valer. En la "Capital Mundial de la Espinaca", la herencia del trabajo duro nos define. Pero durante demasiado tiempo, las empresas que se beneficiaron de la mano de obra de Crystal City —desde los gigantes agrícolas históricos hasta los operadores multinacionales que actualmente explotan los derechos minerales del condado de Zavala— han tratado la salud…
