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.…

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.…

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,…

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.

"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 who watched her three-year-old son Colton suffer a broken femur—the strongest bone in the human body—at a trampoline park during a dedicated toddler session. As Kati told ABC News, "We had no idea. We would have never put our baby boy on a trampoline if we would have known." Colton spent weeks in a full body cast. His family’s life was upended in a single second. If you are reading this in City of Jersey Village, you might be standing exactly where Kati stood: at a hospital bedside, staring at a surgical discharge form, wondering how a Saturday afternoon birthday party turned into a life-altering medical crisis.

In a quiet neighborhood like the City of Hunters Creek Village, parents often feel a sense of security when they take their children to a birthday party or an afternoon of "Toddler Time" at a nearby trampoline park. We see it every weekend: the line of cars heading down I-10 toward the high-energy hubs of Urban Air or Sky Zone, or families gathering in backyard play spaces. But beneath the music and the laughter of jumping children, there is a physical reality that most parents never hear about until it is too late. One bad bounce. One distracted teenager holding a court monitor whistle. One "Wipe-Out" arm that spins too fast. That is all it takes to transform a sunny City of Hunters Creek Village Saturday into a lifetime of orthopedic surgeries and specialized care. At Attorney911, we have spent 25 years standing in the gap between families and the massive corporate conglomerates that own these parks. Our managing partner, Ralph Manginello, has spent his career holding Fortune 500 companies accountable—from the BP Texas City refinery litigation to current $10 million lawsuits against major institutions.

"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 were the words of Kaitlin "Kati" Hill, a mother whose three-year-old son Colton suffered a broken femur and spent weeks in a body cast after a trampoline-park accident. Her warning, shared hundreds of thousands of times, resonates with every parent who has sat in a Humble emergency room waiting for news. At the Urban Air on Highway 59 in Humble or the Cosmic Air in the surrounding metro, families expect that the safety rules are being followed. They expect that the teenage court monitor is properly trained. They expect that the "waiver" signed at a fast-moving kiosk was a fair notice of risk, not a total immunity shield for the park's own negligence. The truth about the trampoline industry is that it operates in a regulatory vacuum. While you might assume a state or federal agency inspects these facilities, no such oversight exists in Texas. The industry exists under a voluntary consensus standard — ASTM F2970-22 — that the trampoline park owners essentially wrote about themselves. When a child 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." For Kaitlin "Kati" Hill, describing the moment her three-year-old son Colton's femur was shattered at a trampoline park, that scream was the end of "family fun" and the beginning of a nightmare. Her story, shared over 240,000 times on social media, resonates with every parent in the City of Houston who has stood in a trauma bay at Texas Children’s Hospital or Children’s Memorial Hermann watching a surgical team stabilize a child’s shattered limb. In the City of Houston, we see this story repeated with clinical precision. It happened to sixteen-year-old Max Menchaca on the first day of his summer vacation at Cosmic Jump in northwest Harris County. He fell through a tear in a trampoline slide, struck the unpadded concrete floor beneath, and suffered a massive traumatic brain injury. While the park pointed to a signed waiver, our legal system held them accountable. A Harris County jury saw through the "paper shield" and awarded $11.485 million—including $6 million in punitive damages—finding the operator grossly negligent. That remains the largest reported…

"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 life changed forever. They were at a "Toddler Time" session in a park that marketed itself as safe for children his age. They had no idea that a single jump on a trampoline shared with a larger jumper could snap the strongest bone in a child's body. Colton’s femur was shattered, and he spent the summer in a body cast. Their story is not an outlier; it is the predictable output of a commercial industry that values throughput over safety. If you are reading this in City of Hedwig Village, perhaps in a waiting room near the Houston Medical Center or at your child’s bedside after an emergency transport from a nearby park, we want you to know one thing clearly: what happened was not an accident. It was the result of a business decision. At Attorney911, we have spent more than 25 years holding massive corporations accountable, from the BP Texas City litigation to our current $10…
