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…

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…

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…

"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…

"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…

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…

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…

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…

"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…

"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…
