The Complete Parent’s Guide to Trampoline Injuries in Sanger, Texas One moment you’re standing at the observation rail of a trampoline park near Sanger, watching your child laugh. The next, the air is cut by a sound no parent should ever hear. As Kaitlin "Kati" Hill told ABC News after her three-year-old son Colton’s femur was shattered during a "Toddler Time" session: "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." Like many families in Denton County, the Hills had no idea. They believed the marketing. They believed the "Toddler Time" designation meant the facility was safe for a child's developing body. They believed the signature at the kiosk was just a routine formality. At Attorney911, we know the truth that trampoline park corporations—and the manufacturers of backyard trampolines—try to hide. Since 1998, Ralph Manginello and our legal team have fought for catastrophic injury victims. We have seen how a Saturday afternoon along the I-35 corridor can turn into a decade of orthopedic surgeries, neurological monitoring, and mounting medical debt. Whether your child was injured at an Urban Air in…

"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 the voice of Kaitlin "Kati" Hill, a mother whose three-year-old son, Colton, suffered a broken femur and was placed in a body cast after a visit to a trampoline park. As Kati told ABC News, she had no idea. Thousands of parents across the country—and right here in City of Roanoke—are in that same position today. They signed a waiver at a kiosk, handed over their hard-earned money, and watched their children walk onto a court that they assumed was safe. Within minutes, their lives changed. If your family is currently sitting in a pediatric trauma bay or navigating the aftermath of a catastrophic fracture, you need more than just a lawyer; you need a system of accountability. At Attorney911, led by managing partner Ralph Manginello, we have spent over 25 years making corporate defendants pay for the consequences of their business decisions.

"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, speaking to ABC News after her son’s femur was shattered at a trampoline park. Her warning, shared more than 240,000 times by parents like you, is the reality we see every week. At Attorney911, we have spent 25 years standing in the gap between families in the City of Pilot Point and the massive corporate conglomerates that own these facilities. When your child is injured on a Saturday afternoon at a park near Denton or Frisco, you are not just dealing with a "freak accident." You are facing a multi-layered insurance system designed to silence you with a signature. We are writing this because, as a parent in Pilot Point, you probably believe that the waiver you signed at the kiosk ended your case. You likely think that because trampolines are "inherently dangerous," the law won't step in to help your child. Our managing partner, Ralph Manginello, has spent over two decades proving those assumptions wrong in federal and state courts. Our…

If your child was injured at a trampoline park in Oak Point or a neighboring North Texas community, what you do in the next seven days will determine whether your family receives justice or whether a corporate risk management team successfully closes your file forever. At Attorney911, led by managing partner Ralph Manginello with over 25 years of trial experience, we know that a trampoline injury is never just a "freak accident." It is the predictable result of a business system that chooses profit margins over the safety specifications mandated by the industry’s own standards. Whether your child suffered a catastrophic break during "Toddler Time" at an Urban Air in Denton or Frisco, or sustained a life-altering spinal injury at a Sky Zone in the North Texas corridor, you are now facing a sophisticated defense machine. The park has already begun its process. They have a waiver they believe is ironclad. They have a surveillance system that is set to overwrite the footage of your child’s injury within weeks. And they have an insurance adjuster who is trained to call you with a friendly tone while building a defense that blames you or your child for the accident. We are…

"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." These words, shared by Kati Hill with ABC News after her three-year-old son Colton suffered a broken femur at a trampoline park, resonate with every parent who has ever stood in a trauma bay in Denton County. Colton spent months in a body cast. Kati’s warning has been shared hundreds of thousands of times because it touches on a terrifying truth that the industry hides: we had no idea. If your family is currently dealing with the fallout of an injury at a trampoline park in City of Little Elm, or if a defective backyard trampoline has changed your life in a single afternoon, you are not alone. And more importantly, the guilt you may feel as a parent does not belong to you. You signed a waiver because the line was long and the kiosk was fast. You let your child jump because you wanted them to have fun. None of that caused the injury. The park was injured because of a system—an architecture of negligence that prioritizes corporate margins…

When a family in Lakewood Village decides to spend a Saturday afternoon at a nearby trampoline park in Frisco, Denton, or Lewisville, they aren’t looking for a legal battle. They’re looking for a birthday party reward, a way to burn off energy during a hot Texas summer, or a safe place for their children to practice gymnastics. They trust that the facility is operated by professionals who follow safety standards. They trust that the "Toddler Time" sessions are actually safe for toddlers. And they trust that the multi-page waiver they clicked through at a digital kiosk is just a standard formality. But as our firm has seen for over 25 years, that trust is often misplaced. What happened to Colton, the three-year-old son of Kaitlin "Kati" Hill, is a nightmare that stays with every parent who hears it. As Kati told ABC News, the moment Colton hit the mat on a court where a larger jumper was also active, his knees buckled and he let out "the worst scream that you could ever have heard from a child." Colton suffered a broken femur and spent weeks in a body cast. His mother’s warning, shared over 240,000 times, echoes the reality…

At a trampoline park in Lewisville or Denton, just a short drive from City of Lake Dallas, the afternoon usually starts with the same routine. You stand at a kiosk, you scroll through screens of fine print, and you tap an "I agree" button while your children pull at your sleeve, anxious to get onto the court. You handed over the credit card, you bought the grip socks, and you believed that because the facility was open to the public, it was safe. Twenty minutes later, the routine changed forever. Maybe it was the sound of the double-bounce—the "rebound energy transfer" that physicists and pediatricians have been warning about for decades. Your child was launching off the mat just as a teenager twice their size landed. In that microsecond, the kinetic force multiplied by four times. Your child didn't just jump; they were catapulted. Then came the scream—what Kati Hill, a mother whose story went viral after a similar incident, called "the worst scream that you could ever have heard from a child." At Attorney911, we know what follows that scream. We know the drive to Medical City Lewisville or the frantic transport to a Level 1 pediatric trauma center…

"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 the voice of Kati Hill, a mother who watched her three-year-old son Colton suffer a broken femur at a trampoline park. She, like so many parents in City of Krum, believed the facility was a controlled, safe environment for a Saturday afternoon. She ended her public warning with five words that haunt every family we represent: "We had no idea." At Attorney911, we know that what happened to your child in City of Krum wasn't a "freak accident."

At a Saturday afternoon birthday party at a trampoline park serving Krugerville families, the atmosphere is usually a blur of neon lights, loud music, and high-velocity motion. Your child is airborne, surrounded by dozens of others in a facility that markets itself as a safe haven for family fun. Then, in two seconds, the double-bounce happens. A heavier jumper lands on the same mat just as your child is pushing off. The energy transfer multiplies the launch force by up to four times, and your child returns to the mat at an angle their developing skeletal system was never engineered to decelerate. The sound that follows is what Kaitlin “Kati” Hill described to ABC News as "the worst scream that you could ever have heard from a child." Her son Colton was only three when his femur snapped at a park during a "Toddler Time" session. Like many parents in Krugerville and throughout Denton County, she was told the waiver she signed at the kiosk ended her right to seek accountability. We are here to tell you that the waiver is not the wall the park wants you to believe it is. At Attorney911, led by Managing Partner 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, telling ABC News what happened the day a trampoline park broke her son's femur. Colton was only three years old. He spent the next several months in a body cast that covered half his tiny body. His mother’s warning was shared over 240,000 times, and every parent in Justin who has ever signed a kiosk waiver at a birthday party knows that cold shiver of recognition. We’ve seen the aftermath of that scream in Justin too many times. At Attorney911, we know that when a child leaves a park on a stretcher, the facility’s first priority isn’t your family’s recovery—it’s their own liability.
