"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 from right here in Texas, describing for ABC News the moment her three-year-old son Colton’s femur was shattered at a trampoline park. Colton was jumping in a "Toddler Time" session—a window specifically marketed to parents of small children as a safe environment. He spent months in a body cast. His mother’s public warning has been shared more than 240,000 times because it resonates with the private fear of every parent in the City of Wilmer who has ever signed an iPad waiver while a line of excited children waited behind them. "We had no idea," Kati said. "We would have never put our baby boy on a trampoline if we would have known." At the Manginello Law Firm—Attorney911—we believe you shouldn't have to find out the hard way. If you are reading this at a hospital bedside or in your home in the City of Wilmer after a trampoline accident, you need to understand one thing clearly: what happened to your child was not…

Imagine a Saturday afternoon in University Park. Your family is transitioning from a morning soccer match at Curtis Park or perhaps a youth clinic near the SMU campus. You decide to reward the kids with a trip to one of the nearby trampoline parks in North Dallas, Frisco, or Grapevine. You stand at the kiosk, the line behind you is long, and you quickly tap "I agree" on a digital waiver so the kids can start jumping. Twenty minutes later, you hear it—the sound that stops every parent's heart. As Kati Hill told ABC News after her three-year-old son Colton broke his femur at a park, it is "the worst scream that you could ever have heard from a child." In an instant, a fun family outing has turned into a nightmare of sirens, trauma bays at Children’s Medical Center Dallas, and a surgeon explaining what happens when a growth plate is destroyed at age nine. We are Attorney911. Since 1998, Ralph Manginello has fought for catastrophic injury victims against the world’s largest corporations. We didn’t build our firm to handle "slip and falls."

Her warning, shared over 240,000 times on social media, resonates with every parent in Seagoville who has ever signed a kiosk waiver while a line of excited children waited behind them. At Attorney911, we have spent more than 25 years standing with families at the trauma-bay bedside, watching surgeons explain what happens when a growth plate is destroyed at age nine.

You were likely there for a birthday party or a "Toddler Time" session. You signed the document on the iPad at the kiosk because the line was long and your child was eager to jump. Then, the double-bounce happened. Or the attendant was looking at a phone while an adult landed on your child’s court. Or the harness on the climbing wall wasn’t checked. "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 Kati Hill, the mother of a three-year-old who suffered a broken femur at a trampoline park.

The Complete Ovilla Parent’s Guide to Trampoline Injury Accountability One Bad Landing. One Broken Life. We Hold the System Accountable. "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 whose three-year-old son Colton suffered a broken femur and was forced into a body cast because of a trampoline park incident. Her warning was shared 240,000 times on social media. We have heard that scream in our practice for over twenty-five years. We represent the parent at the trauma-bay bedside in Ovilla who has just realized that the "safe family fun" they were promised was a business decision made to favor margins over their child's skeletal integrity.

"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." When Kati Hill told ABC News about the day her three-year-old son Colton broke his femur at a trampoline park, she was describing a nightmare that hundreds of families in the City of Mesquite and surrounding Dallas County face every year. Colton wasn't doing backflips or acting recklessly. He was a toddler at a facility that marketed "Toddler Time." His parents had signed the waiver at the kiosk twenty minutes earlier. They, like so many parents in City of Mesquite, had no idea that their child was walking onto a court where the physics were engineered for injury and the safety protocols were treated as optional. At Attorney911, led by Ralph Manginello with over 25 years of experience in catastrophic injury litigation, we have seen exactly how these facilities operate. From our offices in Houston, Austin, and Beaumont, we represent families across Texas—including City of Mesquite—who are tired of being told that their child’s life-altering injury was just a "freak accident" or an "inherent risk." We know better. What happened to…

One bounce. One bad landing. One broken neck. That is the timeline of a catastrophic injury at a trampoline park in Lewisville, and for many families, it is a nightmare that begins in the seconds it takes for a court monitor to check their phone. At the Launch Family Entertainment center off the I-35E frontage road in Lewisville, or the nearby Urban Air and Sky Zone locations serving Denton County, thousands of children are airborne every weekend. They are jumping at facilities that market "safe family fun" while operating under a business model that prioritizes throughput and margin over the survival of your child’s growth plates. When your child comes off a court on a stretcher at Medical City Lewisville, and the manager hands you a clipboard instead of calling 911, you are seeing the first layer of a corporate defense system designed to isolate the park from the consequences of its own decisions. We are Attorney911. With over 25 years of experience fighting Fortune 500 corporations, Managing Partner Ralph Manginello has built a firm that doesn’t just handle personal injury cases—we dismantle corporate liability shields.

"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 Kati Hill, describing the moment a trampoline park broke her three-year-old son’s femur. It is a scream that echoes in the minds of parents across the City of Lancaster and throughout Dallas County every time a weekend birthday party at a local adventure center ends in an ambulance ride. We have heard that story. We have stood in the trauma bays at Children’s Medical Center Dallas. And we have seen the stack of medical bills and the "friendly" phone calls from insurance adjusters that follow. If your child was injured at a trampoline park serving the City of Lancaster or on a defective backyard trampoline in your neighborhood, you are likely feeling a combination of terror, exhaustion, and guilt. You signed the waiver because the line was long and the kiosk was fast. You let your child jump because you wanted them to have fun. You trusted that the park followed the rules. None of this is your fault. A trampoline injury is never just an accident; it 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." That was Kaitlin Hill telling ABC News about the moment her three-year-old son’s life was upended by a broken femur at a trampoline park. It is a scream we have heard echoed in the stories of families across Texas. At The Manginello Law Firm, also known as Attorney911, we know that for parents in Hutchins and across Dallas County, that sound is the beginning of a nightmare. You take your child to a place like Sky Zone, Urban Air, or Altitude expecting a safe afternoon of family fun near the I-45 corridor. You sign a waiver because the line is long and the staff is rushing you. You trust the "court monitors" to keep the big kids away from the little ones. Then the physics of a double-bounce takes over. Within seconds, your child is airborne, then screaming on the mat while an eighteen-year-old attendant looks on, unsure of whether to call 911 because they weren't trained for this. We are not just another personal injury firm in Dallas. We are…
