"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 "Toddler Time" session in a Texas trampoline park. Colton suffered a broken femur, and he spent months in a body cast that reached his chest. "We had no idea," Kati said later, echoing a sentiment we hear from families in the City of San Antonio every week. "We would have never put our baby boy on a trampoline if we would have known." We are Attorney911—The Manginello Law Firm—and we represent families who are living through that nightmare. Since 1998, Ralph Manginello has fought for the victims of catastrophic injuries across Bexar County and the State of Texas.

"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 mother whose three-year-old son Colton suffered a shattered femur at a trampoline park. Like so many families in City of Olmos Park, she was told she was at a place built for "family fun." She was told that "Toddler Time" was a safe, segregated environment for her child’s developing body. She signed a waiver at a kiosk because the line was long and the staff was rushing her through. She believed the park was supervised by trained professionals. She had no idea that her son’s life—and her family’s peace—would change in a single two-second bounce. At Attorney911, we hear these stories every day. We are currently represent families who arrive at the trauma bay in a state of shock, clutching an ice pack and a business card from a park manager who refused to call 911. We represent parents in City of Olmos Park who are watching a pediatric orthopedic surgeon explain that their child’s growth plate has been destroyed at age eight,…

For families in City of Lytle, a Saturday trip up I-35 into San Antonio for a few hours at a trampoline park is a common weekend ritual. You load the kids into the car, you drive past the Lydia’s Mexican Restaurant, enter the highway, and twenty minutes later you’re at a facility like Urban Air or Altitude. You pay the admission, you hand your children the neon wristbands, and you sign the electronic waiver on the iPad kiosk because the line is long and the kids are eager to jump. You assume that because the park is open for business, it is safe. You assume that because there are teenagers in "Court Monitor" shirts standing at the edge of the mats, your child is being watched. You assume the waiver you signed is a standard formality of modern life. Then the double-bounce happens. Your child is airborne, then screaming. The femur—the strongest bone in the human body—snaps under the multiplied force of a 200-pound adult landing on the same trampoline bed. As that sound, which Texas mother Kati Hill described to ABC News as "the worst scream that you could ever have heard from a child," echoes through the facility,…

Throughout the City of Live Oak and the greater San Antonio metro, parents look for safe, high-energy environments like the Urban Air on Fourwinds Drive or The Rush Fun Park just minutes away in Universal City. You bring your children to these facilities because they are marketed as "premier adventure destinations" and "the ultimate indoor playground." You sign the digital form at the kiosk because the line is long and your children are anxious to jump. You believe that "standardized safety rules" and teenage "court monitors" are there to prevent catastrophe. Then, the double-bounce happens. At a trampoline park in Live Oak, a child happens to push off the mat at the exact millisecond a 200-pound adult lands. The resulting energy transfer is not a bounce; it is a launch. Physics dictates that the smaller jumper—your child—is propelled with force multiplied by up to 4x. This is the "catapult effect," and it is the signature mechanism of pediatric trampoline injuries. When Kaitlin "Kati" Hill described her three-year-old son’s femur snapping at a trampoline park, she told ABC News it was "the worst scream that you could ever have heard from a child." If your family is currently dealing with the…

"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 Kaitlin Hill told ABC News about her three-year-old son Colton’s broken femur, she wasn't speaking about a freak accident. She was describing the predictable output of a multi-billion-dollar industry that has scaled a dangerous recreational activity to industrial proportions. That scream has been echoed by thousands of families across Texas and right here in the City of Leon Valley. Colton spent months in a body cast because a heavier jumper landed on his trampoline bed—a mechanism known as a "double-bounce." If you are reading this in a waiting room at University Hospital or any other San Antonio-area trauma center, or if you are at home in the City of Leon Valley watching your child struggle with a heavy, uncomfortable cast, we want you to know three things immediately. First, this is not your fault. You signed the kiosk waiver because you wanted your child to have fun, and the park told you it was safe. Second, the piece of paper you signed is not the absolute shield the park wants…

One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park. For many families in Kirby, a trip to a jump park is a routine Saturday afternoon—a way to escape the South Texas heat and let the kids burn off energy. You walk into a facility like Urban Air, Altitude, or The Rush Fun Park. You wait in a long line at a kiosk. You see a series of screens with dense legal text. You tap "agree" because your child is tugging at your arm, and you handed over your credit card twenty minutes earlier. You assume the park is safe because it is open for business. You assume the staff is trained. You assume the "waiver" you just signed is a formality. Then you hear it. Kaitlin "Kati" Hill, a mother who lived through the nightmare we see every day, told ABC News it was "the worst scream that you could ever have heard from a child." Her three-year-old son, Colton, broke his femur—the strongest bone in the human body—during a "Toddler Time" session. Like so many parents in Kirby and across Bexar County, Kati and her husband later said, "We had no…

In cases of catastrophic trampoline injuries in the City of Hill Country Village, the moments following the accident are often defined by a high-stakes silence. You are in a trauma bay or a quiet hospital room, perhaps at University Hospital or another leading pediatric trauma center serving Bexar County, watching a six-year-old deal with a fracture or a teenager struggle with a concussion. You remember the Saturday afternoon at the park—the bright lights of an Urban Air or the music at The Rush Fun Park in San Antonio—and the quick signature you provided at a kiosk twenty minutes before the world changed. The insurance adjuster will call you within forty-eight hours. They will be friendly. They will ask how your child is doing. Then, they will mention the waiver. They want you to believe that the piece of paper you signed is a total wall between your family and justice. It isn't. At the Manginello Law Firm, we know that piece of paper is often just noise. For over 25 years, Ralph Manginello has fought for families against some of the largest corporate entities in the world, including BP after the Texas City refinery disaster. Our firm is built for…

"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, describing the moment a trampoline park changed her family’s life forever. Colton’s femur—the strongest bone in the human body—snapped during a "Toddler Time" session that was supposed to be a safe environment for small children. As Kati told ABC News, "We had no idea. We would have never put our baby boy on a trampoline if we had known." We hear these stories far too often at Attorney911. Families in Helotes and across Bexar County visit places like Urban Air in San Antonio or Altitude Trampoline Park expecting safe family fun, only to leave in an ambulance headed for University Hospital or the Children’s Hospital of San Antonio.
