"Sus pies golpearon la colchoneta, y casi instantáneamente sus rodillas se doblaron, y simplemente soltó el peor grito que jamás se podría haber escuchado de un niño". Cuando Kaitlin "Kati" Hill le contó a ABC News sobre el momento en que el fémur de su hijo Colton, de tres años, se partió en un parque de trampolines, estaba dando voz a una pesadilla que se ha convertido en una realidad semanal en las salas de emergencias del Valle del Río Grande. Colton pasó meses con un yeso de cuerpo completo. Su familia no tenía idea de que el peligro existía hasta que el hueso se rompió. Al igual que muchas familias en la ciudad de Alton y en todo el condado de Hidalgo, confiaron en que una instalación comercializada para niños estaría diseñada para su seguridad. En Attorney911, conocemos la verdad que la industria multimillonaria de los trampolines intenta ocultar tras las exenciones de responsabilidad de los quioscos y las colchonetas de colores brillantes: estas lesiones no son "accidentes fortuitos". Son los resultados predecibles de decisiones comerciales tomadas por conglomerados matrices como Sky Zone, Inc. y Unleashed Brands. Ya sea que su hijo se haya lesionado en un Urban Air en McAllen, en un Xtreme Jump en Harlingen o en un Jumpking de patio trasero en un vecindario de Alton, nuestra firma fue creada para esta lucha específica. Estamos dirigidos por Ralph Manginello, un abogado litigante con más de 25 años de experiencia en litigios de casos de lesiones catastróficas…

"Sus pies tocaron la lona y, casi al instante, se le doblaron las rodillas y soltó el peor grito que jamás se le haya escuchado a un niño".

Waller Trampoline Park Injury Attorneys Attorney911 of Houston, TX provide the Insider Advantage with Ralph Manginello’s 25+ years of Federal Court experience and former recreational-defense insider Lupe Peña to defeat Sky Zone and Urban Air waivers for pediatric TBI, SCIWORA, Salter-Harris growth plate, and rhabdomyolysis injuries using ASTM F2970, EN ISO 23659:2022, and AAP standards while leveraging industry-leading case anchors like the Cosmic Jump $11.485M Harris County verdict and Damion Collins $15.6M Urban Air arbitration against corporate parents Palladium Equity and Unleashed Brands, representing families in Waller for backyard manufacturer defects (Jumpking, Skywalker, Springfree) and adjacent-attraction Sky Rider strangulation patterns or climbing wall falls with DVR forensic imaging, Delfingen bilingual defense-breaking tactics, and a no-fee guarantee unless we win at 1-888-ATTY-911.

One bounce. One bad landing. One broken neck. For many families in Waller, that is all it takes for a Saturday afternoon at a trampoline park to turn into a life-altering tragedy. At the Sky Zone or Urban Air locations serving the Waller area, children are airborne every few seconds. Most of them land safely. But when they don’t, the consequences are often catastrophic. We’ve seen the aftermath: seven-year-olds leaving facilities on stretchers, and parents standing in trauma bay waiting rooms at Texas Children's Hospital in Houston, clutching a wristband and a signed kiosk waiver, wondering how a "fun" birthday party ended in a body cast. The industry wants you to believe that what happened to your child was a fluke—a "freak accident" or an "inherent risk" of jumping. We know better. With over 25 years of experience in catastrophic injury litigation, Ralph Manginello and our team at Attorney911 have seen how these facilities operate. Your child’s injury wasn't an accident. It was the predictable output of a business model that prioritizes throughput and margin over pediatric safety. Whether your child was hurt at a commercial park along the US-290 corridor or on a weather-degraded backyard trampoline in a Waller neighborhood, you are now facing an insurance machine designed to silence your claim. They have risk management teams, corporate defense firms, and waivers drafted by lawyers to protect their bottom line. You need someone who fights back—a firm that knows the safety standards they violated and the corporate shells they…

In Harris County, Texas, the sound of laughter at a birthday party can transform into a life-altering medical emergency in less than two seconds. For families in City of West University Place, a Saturday trip to an indoor adventure park or a neighbors backyard gathering is supposed to be about exercise and community. However, beneath the surface of bright colors and upbeat music at parks across the Houston metro—from Sky Zone and Urban Air to Altitude and the historic site of Cosmic Jump—lies a systemic failure of safety that we have spent over twenty-five years exposing. We’ve seen what happens when the physics of a trampoline meets the developing body of a child. We have stood at the bedside of children in the Texas Medical Center, just minutes from City of West University Place, watching surgeons explain why a growth plate injury at age eight means a decade of corrective procedures. At Attorney911, led by Ralph Manginello, our mission is to peel back the layers of corporate protection that national chains use to hide the truth: trampoline injuries aren’t accidents. They are the predictable output of business decisions that prioritize profit margins over the safety of the children in City of West University Place. If your child was injured in a trampoline accident, you are likely facing an insurance adjuster who is already pointing at a kiosk waiver and a park manager who refused to call 911. We are here to tell you that the waiver isn't a wall, and…

One bounce. One bad landing. One broken neck. That is all it takes at a commercial trampoline park on a Saturday afternoon in the City of Webster. At the Urban Air Adventure Park on the Gulf Freeway or the Altitude Trampoline Park just down the road, a seven-year-old can come off a court on a stretcher in less than thirty seconds. Her parents likely signed a digital waiver at a kiosk twenty minutes earlier, believing the marketing that promised "safe family fun." They had no idea that the piece of paper they signed was drafted by corporate lawyers to be a shield for gross negligence. They had no idea that the "court monitor" watching their child was a sixteen-year-old with four hours of training and no CPR certification. Most importantly, they had no idea that in Harris County, Texas, the waiver is not the wall the park wants you to believe it is. In a landmark Harris County case, 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. The waiver was signed. The jury found gross negligence anyway. That is the largest reported jury verdict against a U.S. commercial trampoline park, and it happened right here in our backyard. At Attorney911, we have spent 25 years making corporate defendants pay for the decisions they make to prioritize margin over children's lives. Our managing partner, Ralph Manginello, has…

The moment your child enters a trampoline park in City of Waller, the environment is carefully calibrated to feel like a world of safe, high-energy fun. The music is loud, the lights are neon, and the waivers are signed on a fast-moving kiosk before you even have a chance to look at the courts. But twelve minutes later, a single landing can change your family’s life forever. We’ve seen the aftermath of that landing. We’ve stood with families in the trauma bays of West Houston, and we’ve heard the same story: "We had no idea." As Kati Hill told ABC News after her three-year-old son Colton suffered a broken femur that required a body cast, she let out “the worst scream that you could ever have heard from a child.” Her warning was shared 240,000 times because parents sense a truth the industry tries to hide: the "accident" your child suffered was the predictable output of a business decision. At the Manginello Law Firm, we don’t treat trampoline injuries like simple slip-and-fall cases. We approach them as corporate accountability investigations. Our founder, Ralph Manginello, brings 25 years of experience litigating against Fortune 500 companies and multinational corporations like BP. Our associate attorney, Lupe Peña, once defended insurance companies and recreational businesses against the exact claims we now file. He knows the playbook they use to hide evidence, and he knows how to dismantle the same waivers he once drafted. In City of Waller, whether your injury happened at an Urban…

"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 Kati Hill described the moment her three-year-old son’s life changed at a "Toddler Time" session. It is a scream we have heard echoed in the stories of families across the City of Tomball and throughout Harris County. We represent families who walked into a place like Urban Air or Sky Zone for a Saturday afternoon of fun and walked out with a child in a body cast or a teenager facing a lifetime of neurological deficit. What happened to your child in City of Tomball wasn't a "freak accident" or an "unlucky break." It was the predictable output of a business model that puts profit margins ahead of pediatric safety. For over 25 years, Ralph Manginello and our team at Attorney911 have stood at the hospital bedsides of catastrophic injury victims. We have gone toe-to-toe with multinational corporations like BP, Walmart, and Amazon. The private equity sponsors behind the big trampoline chains — Palladium Equity Partners and Seidler Equity Partners — don't bring anything to the table that we haven't already beaten in federal and state courts. If your child was hurt at a trampoline park near City of Tomball, you are likely being told that the waiver you signed at the kiosk ended your case before it began. That is the first lie the insurance adjuster will…

Attorney911: The Premier City of Taylor Lake Village Trampoline Park Injury & Pediatric Catastrophic Litigation Firm Led by Ralph P. Manginello (25+ Years Experience) and Lupe Peña (Former Recreational-Business Defense Insider) Defeating Sky Zone and Urban Air Waivers with Cosmic Jump $11.485M Harris County Verdict & Damion Collins $15.6M Arbitration Authority; Expert Prosecution of ASTM F2970 and EN ISO 23659:2022 Standards for TBI, SCIWORA, Salter-Harris Growth Plate, and Rhabdomyolysis Claims Involving Sky Rider Strangulations and Backyard Jumpking or Skywalker Defects; Federal Court Admitted BP Texas City Veteran Holding Palladium Equity and Unleashed Brands Accountable; Hablamos Español with Delfingen Doctrine Edge; Free Consultation & 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 describing to ABC News the moment her three-year-old son Colton’s femur—the strongest bone in the human body—snapped during a "Toddler Time" session at a trampoline park. Like thousands of families in Taylor Lake Village, Kati trusted that a facility marketed for children was safe. She later wrote five words that every parent at a hospital bedside eventually whispers: "We had no idea." We at Attorney911 have heard those words too many times. Whether your child was injured at an Urban Air near Webster, an Altitude Trampoline Park along the I-45 corridor, or on a Jumpking backyard trampoline in a Taylor Lake Village cul-de-sac, the story is often the same. You were told it was a place for safe family fun. You were handed a wristband and a waiver. Minutes later, your life changed. A trampoline injury is never just an accident. It is the predictable output of a business decision. At The Manginello Law Firm, we don't treat these as simple slip-and-falls. We treat them as the corporate accountability cases they are. Managing partner Ralph Manginello brings over 25 years of experience litigating against Fortune 500 giants like BP and Walmart. Our associate attorney, Lupe Peña, used to sit on the other side of the table, defending the insurance companies and recreational venues that now try…

In the quiet, leafy neighborhoods of City of Spring Valley Village, where families value community, safety, and the well-being of their children, the local trampoline park or back-yard setup often seems like a harmless rite of passage. But every Saturday afternoon, at industrial-scale facilities just a short drive down the Katy Freeway or across the West Loop, a business system is operating that prioritizes margin over your child’s skeletal integrity. At Attorney911, we have spent more than twenty-five years standing at the bedsides of families whose lives were altered in a single, catastrophic bounce. We have seen what happens when the physics of a trampoline bed—engineered to multiply force—meets the developing bones of a child who was never warned about the risks. One bad landing. One distracted teenager on a phone instead of monitoring a court. One "double-bounce" that launches a sixty-pound child with four times the force of gravity. That is all it takes to transition from a birthday party celebration to a trauma bay at Texas Children’s Hospital or Memorial Hermann. We are not just a personal injury firm that "handles" these cases; we are a firm that dismantled the industry’s defenses before the first phone call was even made. Our founder, Ralph Manginello, brings over two decades of trial experience, including federal court admission to the Southern District of Texas. Our team includes Lupe Peña, an attorney who used to sit on the other side of the table—defending insurance companies and the very recreational businesses we now…

In the City of Southside Place, a Saturday afternoon often means heading toward the West Loop or down US-59 to one of the dozens of high-intensity trampoline parks that saturate the Houston metro. You take your children there because it is advertised as "safe family fun," a controlled environment where the energy of a weekend can be burned off in a padded arena. But for families in the City of Southside Place, the transition from a birthday party to a pediatric trauma bay at Texas Children’s Hospital can happen in less than two seconds. One minute, you are watching from the rail; the next, you hear what Kati Hill described to ABC News as "the worst scream that you could ever have heard from a child." What many operators in the City of Southside Place area won't tell you is that their business model relies on you believing a myth: that the waiver you signed at the kiosk ended your legal rights before your child even touched the mat. At Attorney911, we have spent 25 years dismantling that myth. Led by Ralph Manginello, our firm brings over two decades of trial experience in federal and state courts to the fight against the multi-billion-dollar conglomerates that own brands like Sky Zone, Urban Air, Altitude, and DEFY. We don’t just "handle" personal injury cases; we build architectures of accountability against corporate giants, from the BP Texas City refinery litigation to our current $10 million lawsuit against the University of Houston involving rhabdomyolysis…
