"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 Kati Hill, a Texas mother whose three-year-old son Colton suffered a broken femur at a trampoline park. Her warning, shared a quarter of a million times on social media, ended with a realization that haunts every parent standing in a trauma bay in Westlake: "We had no idea." One bounce. One bad landing. One life altered forever. That is the reality behind the bright lights and neon colors of the trampoline parks serving Westlake. Whether your child was injured at the Urban Air in Southlake, a Sky Zone in Irving, or on a backyard Jumpking or Skywalker trampoline in a Westlake neighborhood, you are likely hearing the same thing from insurance adjusters and park managers: "You signed the waiver. There is nothing you can do." We are here to tell you that they are wrong. In Texas, and across the nation, a signed piece of paper is not a license for a corporation to maim your child. At Attorney911, led by managing partner Ralph Manginello with…

One bounce. One bad landing. One shattered life. For families in Trophy Club, a Saturday afternoon at a nearby indoor park or a summer day on a backyard trampoline is supposed to be about laughter and high-energy fun. But in the emergency rooms serving Trophy Club and across Denton County, we see a different story. We see the "worst scream you could ever hear from a child," as Kati Hill described the moment her three-year-old’s femur snapped during a "Toddler Time" session. It is a sound that stays with a parent forever. It is also a sound that usually results from a business decision made by a corporation in a boardroom far from Trophy Club—a decision to prioritize traffic over safety, margin over court monitors, and profit over your child’s spinal cord. At Attorney911, we don't view these incidents as "freak accidents." We view them as the predictable output of a system designed to maximize revenue and minimize accountability. Whether your child was injured at an Urban Air location near Trophy Club, an Altitude Trampoline Park in the Fort Worth-Keller corridor, or on a defective Jumpking or Skywalker trampoline in your own backyard, we know the legal architecture of these…

In Harris County, Texas, a jury awarded $11.485 million — including $6 million in punitive damages — against the operator of Cosmic Jump in Houston 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, just a short drive from the Town of Westlake. It is exactly the kind of case we are built to handle. When your child is injured at a trampoline park, you are often told that the piece of paper you signed at the front desk ended your right to seek justice. You are told it was a "freak accident." You are told that "kids will be kids." At Attorney911, we know the truth that the insurance adjusters and corporate risk managers for Sky Zone, Urban Air, and Altitude don’t want you to hear: a trampoline injury is never an accident. It is the predictable output of a business decision. We are The Manginello Law Firm. Led by Ralph Manginello, who brings over 25 years of trial experience…

"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 at a trampoline park. Colton suffered a broken femur that required months in a body cast. His mother’s subsequent Facebook warning was shared over 240,000 times because it resonated with a terrifying truth every parent in the Town of Trophy Club needs to hear: we had no idea how dangerous these facilities truly are. If your child was injured at a trampoline park near the Town of Trophy Club, or in a neighbor’s backyard, you are likely reading this in a state of shock, guilt, and mounting medical anxiety. You may be sitting in a waiting room at Cook Children’s Medical Center or Children’s Medical Center Dallas, watching a surgeon explain what a Salter-Harris growth plate fracture means for your daughter’s next ten years of physical development. You might have already received a "friendly" phone call from an insurance adjuster asking you to "walk through what happened" or offering a $3,000 check to cover your ER…

"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 Hill, a mother who watched her three-year-old son Colton suffer a broken femur in a body cast after what was supposed to be a fun afternoon at a trampoline park. As she told ABC News, "We had no idea. We would have never put our baby boy on a trampoline if we would have known." If you are reading this in a hospital waiting room or at your kitchen table in Shady Shores after a similar nightmare, we want you to know three things immediately. First, what happened to your child wasn't a "freak accident"—it was the predictable result of an industry that often weights profit margins more heavily than pediatric safety. Second, the waiver you signed on that iPad at the front desk is not the absolute shield the park wants you to believe it is. Third, the evidence of what actually happened—the surveillance video, the attendant logs, the incident reports—is being overwritten or "revised" as we speak. At Attorney911, led by Ralph Manginello…

"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 was Kaitlin Hill telling ABC News what happened when her three-year-old son Colton’s femur snapped during a "Toddler Time" session at a trampoline park. Like so many families in Ponder, Texas, she was told the environment was safe. Like so many, she later realized she had been sold a version of safety that didn’t exist. "We had no idea," she said. "We would have never put our baby boy on a trampoline if we had known." We hear these stories in our offices every week. For over 25 years, Ralph Manginello and the team at Attorney911 have stood with families across Texas when catastrophic corporate negligence changes a life in a single second.

That is Kaitlin "Kati" Hill, a mother whose warning post about a trampoline park injury to her three-year-old son, Colton, was shared over 240,000 times on social media.

Town of Hackberry Trampoline Injury Guide: Accountability for Texas Families One moment, your son was launching toward a basketball rim at a park near Town of Hackberry. The next, he let out what Texas mother Kati Hill once described to ABC news as "the worst scream that you could ever have heard from a child."
