"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, a Texas mother whose three-year-old son, Colton, suffered a broken femur at a trampoline park.

We represent the parent standing at a hospital bedside in a Tarrant County trauma bay, watching a surgeon explain what happens when a growth plate is destroyed at age nine.

"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, a Texas mother, telling ABC News about the moment a trampoline park broke her three-year-old son Colton's femur. Her warning was shared over 240,000 times on social media. We have read it. We have heard it from families in our own offices.

"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 at a trampoline park. Her warning, shared over 240,000 times on social media, echoes what we hear every week at our firm. She ended her message with five words that define the tragedy of the indoor jump industry: "We had no idea." If you are reading this in Crowley, at your child’s bedside at Cook Children’s Medical Center or at home as you juggle follow-up appointments and mounting medical bills, you likely feel the same way. You were at the Urban Air on West Mansfield Highway or the Ninja Kidz Action Park right here on East Main Street. You signed the electronic waiver at the kiosk because the line was long and the staff was pressuring you to move quickly so the kids could jump. You believed that "industry safety standards" meant your child was protected. The truth is much darker. A trampoline injury is never an accident—it is the predictable output of a…

"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, a Texas mother, describing the exact moment a trampoline park in our region shattered her three-year-old son’s femur. Her warning was shared 240,000 times because it captures the visceral terror felt by every parent in Colleyville who has ever signed an electronic waiver at a kiosk while their children pulled at their arms to get onto the court. At Attorney911, we know that scream. We have spent more than 25 years representing families in Colleyville and across Texas who have been forced to watch their children navigate life in a body cast, a wheelchair, or a trauma bay because a billion-dollar recreational industry decided that profit margins were more important than ASTM F2970 safety ratios.

The Burleson Parent’s Complete Guide to Trampoline Park and Backyard Injuries One Bounce. One Bad Landing. One Broken Life. At the Urban Air or Altitude parks serving families in Burleson, a seven-year-old child can come off a court on a stretcher in less than thirty seconds. Her parents likely signed a waiver at a digital kiosk twenty minutes earlier. They were told it was a requirement for "fun." Now, as they sit in the trauma-bay waiting room at Cook Children’s Medical Center in Fort Worth, they are being told that their daughter’s life has changed forever. We have spent more than 25 years standing at the bedsides of families just like yours. Our managing partner, Ralph Manginello, has spent over two decades holding multibillion-dollar corporate defendants accountable for catastrophic injuries. We have seen the same pattern repeat from Houston and Austin to the neighborhoods of Burleson. A park decides to prioritize profit margins over safety ratios. A manufacturer sells a backyard trampoline that the American Academy of Pediatrics (AAP) has warned against for twenty-five years. A child pays the price.

The Worst Scream: A Warning for Every Parent in City of Blue Mound Our firm knows the sound. It is a sound that breaks the air in North Fort Worth hospitals like Cook Children's Medical Center and Texas Children's daily. It is "the worst scream that you could ever have heard from a child," as Texas mother Kati Hill described it to ABC News after her three-year-old son, Colton, suffered a broken femur during a "Toddler Time" session at a trampoline park. Kati, like so many parents in City of Blue Mound, had no idea. She believed the marketing. She believed that because the park had a designated time for small children, the staff was trained and the environment was safe. Today, Colton is a survivor, but his story—and the hundreds of others we have documented—remains a terrifying reminder of what happens when a business decision to cut costs meets the brutal physics of a trampoline bed. We are Attorney911, led by managing partner Ralph Manginello. For over 25 years, our firm has stood in the gap for families facing catastrophic, life-altering injuries. We have litigated against multinational corporations like BP and retail giants like Walmart. We are currently pursuing…

The Bedford Parent's Guide to Trampoline Park Injuries and Recovery One Bounce. One Landing. One Broken Life. It usually starts with a Saturday afternoon birthday party at the Urban Air on Airport Freeway or a summer outing to the Sky Zone near Hurst. You stand at the observation rail in a City of Bedford trampoline park, watching your child laugh, surrounded by the high-energy music and the rhythmic thud of dozens of jumpers hitting interconnected mats. Then, the sound changes. It is a sound that Kaitlin "Kati" Hill described to ABC News as "the worst scream that you could ever have heard from a child." Kati’s son Colton was three years old when his knees buckled on a trampoline mat, snapping his femur—the strongest bone in the human body. He spent the next several months in a body cast. Like many City of Bedford parents, Kati later said, "We had no idea. We would have never put our baby boy on a trampoline if we would have known." At Attorney911, we have spent 25 years standing at the bedsides of families who "had no idea." We represent the parents in the trauma bay at Cook Children’s Medical Center or Children’s…

"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 Colton’s life changed at a trampoline park. If you are reading this in a waiting room at Cook Children’s Medical Center in Fort Worth or sitting at your kitchen table in Azle while your child sleeps in a body cast in the next room, we know the weight you’re carrying. You didn't go to the park for a lawsuit. You went for a birthday party, a Saturday afternoon escape from the Texas heat, or a reward for good grades. You signed the waiver on the iPad because the line was long and the kids were excited. You handed over your credit card and your trust. Then the double-bounce happened. Or the attendant was on his phone while your child climbed the wall. Or the foam pit was so compacted that it offered no more protection than the concrete floor beneath it. We are The Manginello Law Firm, known to families across Texas as Attorney911. Since 1998, our founder 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 is Kaitlin "Kati" Hill, a mother from right here in North Texas, describing the moment a Saturday afternoon at a trampoline park turned into a nightmare for her three-year-old son, Colton. Colton didn’t fall off the trampoline. He didn’t try a backflip he wasn’t ready for. He was simply jumping in a designated "Toddler Time" zone when a larger child landed on the same mat. The transfer of energy—a physical phenomenon industry experts call "the double bounce"—snapped Colton’s femur. He spent the next several weeks of his life in a body cast that wrapped around his small waist and down his legs. Kati’s warning to other families was shared over 240,000 times on Facebook. We read it. We’ve seen the evidence behind it. And we know that for every family in the City of Arlington, these stories are no longer far away. When your child is airborne at an Urban Air or a Sky Zone in the City of Arlington, they are not just playing. Physically, they are interacting with…
