"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…

En el condado de Harris, Texas, el veredicto del jurado más grande reportado contra un parque de trampolines comerciales en los EE. UU. sigue siendo una indemnización de 11.485 millones de dólares, que incluyó 6 millones de dólares en daños punitivos. La víctima fue un joven de 16 años en el noroeste de Houston que cayó a través de un tobogán de trampolín roto en un parque llamado Cosmic Jump, golpeando el suelo de concreto debajo de las colchonetas y sufriendo una lesión cerebral traumática que le cambió la vida. La defensa del parque fue que la familia había firmado una renuncia de responsabilidad. El jurado del condado de Harris vio a través de esa defensa, encontrando que el operador del parque fue gravemente negligente a pesar de esa firma. Al brindar asesoría legal a las familias de la Ciudad de South Houston y el área metropolitana circundante, comenzamos cada caso con esa realidad local: una renuncia no es un muro, y una lesión en un trampolín nunca es un "accidente". En el bufete de abogados Manginello Law Firm, también conocido como Attorney911, reconocemos que cuando su hijo sale de una zona de trampolines en un parque en la Ciudad de South Houston con una tibia destrozada o una lesión en el cuello, usted no está buscando a un médico general. Necesita una firma que comprenda la física específica de la transferencia de energía, los estándares de la industria escritos por los propios parques y la arquitectura corporativa diseñada para…

"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, describing the moment a trampoline park visit in North Texas turned into a life-altering disaster. Her son suffered a broken femur that required months in a body cast. Her warning to other families was shared over 240,000 times because it resonated with a terrifying truth that many parents in Piney Point Village don't realize until they are in an emergency room: we had no idea. At the Manginello Law Firm, also known as Attorney911, we have spent over 25 years representing families who find themselves in that same state of shock. We have seen the medical records from Texas Children’s Hospital and Memorial Hermann. We have stood with the parents who signed a waiver at a kiosk in seconds, only to be told by a corporate insurance adjuster days later that they have no right to seek justice. In Piney Point Village, where backyard trampolines are common and commercial parks like Urban Air, Sky Zone, and Altitude are a short drive down the Katy Freeway or West Loop, these injuries are not freak accidents. They are the predictable output of a multi-billion-dollar industry that prioritized profit margins over pediatric safety. If your child was hurt at a trampoline park serving Piney Point Village, or on a defective residential trampoline in a Harris…

"Sus pies tocaron la colchoneta, y casi instantáneamente sus rodillas cedieron, y simplemente soltó el peor grito que jamás se haya escuchado de un niño". Así fue como Kaitlin "Kati" Hill describió el momento en que el fémur de su hijo de tres años, Colton, se fracturó en un parque de trampolines. Ella le dijo a ABC News que, a pesar de la publicidad del "Tiempo para Niños Pequeños" (Toddler Time), su hijo salió lanzado por la transferencia de energía de un saltador más grande. Su advertencia fue compartida 240,000 veces por padres que, al igual que ella, no tenían idea de que la "diversión" por la que estaban pagando era un riesgo calculado que el parque decidió ignorar. Si está leyendo esto en una sala de espera del Texas Children’s Hospital o del Memorial Hermann Southeast después de un sábado por la tarde en un parque de trampolines en Pasadena, sabemos exactamente lo que está sintiendo. Usted firmó el documento en el iPad. Vio a su hijo entrar en la colchoneta. Siente un peso de culpa que la compañía de seguros quiere usar para mantenerlo en silencio. Pero aquí está la verdad de parte de una firma que ha pasado 25 años luchando contra la negligencia corporativa: lo que le sucedió a su hijo en Pasadena no fue un "accidente". Fue el resultado predecible de un modelo de negocio que prioriza el volumen de clientes y los márgenes de beneficio por encima de la seguridad de las familias de…

For most families in Nassau Bay, a trip to a nearby trampoline park in Webster or a weekend jumping in a Clear Lake backyard feels like a safe way to burn off energy. But for us at Attorney911, these venues represent something different. We see the medical charts. We see the radiographic evidence of vertebral artery dissections and Salter-Harris growth plate fractures. We see the 11 PM terror of a parent sitting in a trauma bay at Texas Children’s Hospital in the Bay Area, wondering how a "supervised" environment produced a life-altering injury. If your child was injured at a trampoline park serving Nassau Bay, or on a defective backyard trampoline in one of our neighborhoods near the Johnson Space Center, you aren't just dealing with an "accident." You're dealing with the output of a business model that often prioritizes throughput over the safety standards our industry wrote for itself. One Bad Landing in Nassau Bay: Why We Fight for These Families Imagine a Saturday afternoon at an Urban Air or an Altitude near NASA Road 1. The court is packed. The music is loud. The attendant—likely a seventeen-year-old hired two weeks ago—is balancing his attention between four different courts. Your child pushing off a trampoline mat is met with the downward force of a teenager three times his size landing on that same bed. In two seconds, the physics of energy transfer multiplies your child's launch force by up to four times. His knees buckle. He lets out what…

In Harris County, a Saturday afternoon is supposed to be about laughter, birthday cake, and the salt-air breeze off Galveston Bay. But for too many families in City of Morgan's Point, that afternoon ends with "the worst scream you could ever have heard from a child." That is how Kati Hill described the moment her son’s femur snapped during a "Toddler Time" session. It is a sound we have heard described by parents from the Houston Heights to the coastal neighborhoods of City of Morgan's Point. At Attorney911, we know that when your eight-year-old is rushed from a trampoline park toward Texas Children’s Hospital with a shattered tibia, the park’s management won't offer a hand—they’ll offer a clipboard. They want you to believe that the waiver you signed at a kiosk in seconds ended your legal rights before your child even touched the mat. They are wrong. We have spent more than 25 years making corporate defendants accountable. From litigating against multinational giants in the BP Texas City refinery explosion to our current $10 million lawsuit against the University of Houston regarding rhabdomyolysis and acute kidney failure, Ralph Manginello and our team have seen every tactic in the corporate-defense playbook. We even have an attorney, Lupe Peña, who used to sit on the other side of the table defending these very businesses. He knows exactly where the holes are in their "airtight" waivers. If your child was injured at a trampoline park serving City of Morgan's Point or on a…

In a quiet neighborhood off Spencer Highway or near the shaded streets of Fairmont Park here in La Porte, the sound of a spring-loaded mat and the laughter of children is a staple of Texas suburbia. Many families in our community choose the backyard trampoline as a way to burn energy during those humid Gulf Coast afternoons. Others make the short drive up Highway 146 to the massive indoor adventure hubs like Sky Zone in Baytown, Urban Air in Pasadena, or Altitude in Webster. But we have seen how quickly that laughter turns into a sound no parent ever forgets. At The Manginello Law Firm—known to the families we represent as Attorney911—we know that sound because we have stood at the bedsides of children in trauma centers from Texas Children’s Hospital to Children’s Memorial Hermann. We have heard what Kati Hill, a mother whose son Colton’s femur was shattered at a park, called "the worst scream that you could ever have heard from a child." You are likely reading this at 11 PM in a hospital waiting room or on your couch after a long, quiet drive home from the emergency room. You are dealing with a mixture of terror, confusion, and a crushing sense of guilt. You signed a waiver at a kiosk. You let your child jump because you wanted them to have fun. The first thing we need to tell you is this: None of this is your fault. What happened to your child wasn't a "freak…

One bounce. One bad landing. One life forever altered. At the trampoline parks serving the City of Katy, a Saturday afternoon birthday party can turn into a surgical emergency in less than two seconds. You were in the observation area of a park near the Katy Freeway or watching from the sideline of a backyard in Cinco Ranch. You signed the waiver at the kiosk because the line was long and the staff was pressuring you to hurry so the kids could get their wristbands. You believed the advertisements that promised "safe family fun." Then you heard it. Kaitlin Hill, a mother whose story went viral after her three-year-old son Colton broke his femur at a park, described it as "the worst scream that you could ever have heard from a child." At our firm, we hear that scream in every file we open. We are Attorney911—The Manginello Law Firm.
