One bounce. One bad landing. One broken neck. That is all it takes at an indoor trampoline park. At the Altitude Trampoline Park near the City of Shavano Park on IH-10, or the nearby Urban Air locations in San Antonio, a seven-year-old child can come off a court on a stretcher in less than thirty minutes. Their parents likely signed the kiosk waiver only moments before, believing the facility was a safe environment for a Saturday afternoon birthday party. We have seen this nightmare unfold for families across Texas for over two decades. What follows is not an accident—it is the predictable output of a system that puts profit margins ahead of child safety. At Attorney911, we have spent 25+ years holding corporate defendants accountable, and we are launching our dedicated trampoline injury practice to ensure that families in the City of Shavano Park have the aggressive, experienced representation they need when the unthinkable happens. When your child is airborne at a park serving the City of Shavano Park, they are moving at velocities that their developing musculoskeletal system was never engineered to decelerate. The American Academy of Pediatrics (AAP) has been warning parents since 1999 that trampolines do not belong in homes or in routine recreational use. Yet, corporations like Sky Zone, Inc. and Unleashed Brands continue to scale these risks to an industrial level. In the City of Shavano Park, where backyard trampolines are common in affluent neighborhoods and commercial jump parks are a short drive down Loop…

"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 a mother named Kati Hill, describing the moment a trampoline park shattered her three-year-old son’s femur. Her warning has been shared hundreds of thousands of times by parents who, in her words, "had no idea" that a Saturday afternoon outing could end in a body cast. If you are reading this in a hospital room at University Hospital in San Antonio or sitting at your kitchen table in Selma after a similar nightmare, we want you to know two things: what happened to your child wasn't a "freak accident," and the waiver you signed is not the final word on your family's future. For over 25 years, Ralph Manginello and our team at Attorney911 have stood in the gap between families and the massive corporations that prioritize profit over pediatric safety. We have gone toe-to-toe with Fortune 500 giants like BP, Walmart, and Amazon. We carry that same battle-hardened discipline into every trampoline injury case we handle. We aren't just personal injury lawyers; we are a specialized practice that has memorized ASTM F2970, analyzed the five layers of the corporate defendant stack, and built a medical litigation architecture that connects the dots between a trampoline bounce and lifelong disability. Whether your injury occurred at the Urban Air in Universal City, The Rush Fun Park on Pat…

"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 Kati Hill, a Texas mother, describing to ABC News the moment her three-year-old son Colton’s femur was shattered during "Toddler Time" at a trampoline park. Her story was shared 240,000 times because it resonates with the terror every parent feels when a day of family fun in City of Schertz turns into a nightmare in a trauma bay. We read her story not as an isolated incident, but as the predictable result of a multi-billion-dollar industry that has spent decades operating under its own rules while ignoring pediatric medical consensus. If your child was injured at a trampoline park in City of Schertz or on a backyard trampoline in Guadalupe County, you are likely hearing two things from the people responsible. First, that it was a "freak accident." Second, that the waiver you signed at the kiosk or the warning on the box ends your legal rights. Both are wrong. At Attorney911, led by Ralph Manginello with over 25 years of catastrophic injury experience, we operate from a different premise: a trampoline injury is never an accident; it is the output of a system that puts profit margins ahead of child safety. We represent families in City of Schertz and throughout Texas who are facing life-altering diagnoses—traumatic brain injuries, spinal cord infarctions, Salter-Harris growth plate fractures, and rhabdomyolysis.

At a birthday party near Sandy Oaks, the music is loud, the air is thick with the scent of concession-stand pizza, and your child is doing exactly what you paid for them to do: having the time of their life. You stood at the kiosk twenty minutes ago, scrolled through several screens of legal text you didn't have time to read with a line of parents behind you, and tapped "I agree." You handed your child a colored wristband, watched them race onto the court, and for a moment, everything felt like safe, high-energy fun. Then the double-bounce happened. In less than two seconds, the kinetic energy of a much larger jumper transferred through the trampoline bed and launched your child with four times the force they could have generated on their own. They didn't just jump; they were catapulted. The landing didn't happen on the center of the mat. It happened on the edge, where a spring cover had slipped just enough to expose the steel coils beneath. You heard it before you saw it. As Kati Hill, the mother of a three-year-old who suffered a broken femur at a similar park, told ABC News: "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." In Sandy Oaks, when that scream happens, your life changes. You find yourself in the back of an ambulance on the long, quiet drive toward…

"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.

"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, and that the bone may never grow straight again. What happened to your family in City of Olmos Park wasn't an accident. It was the predictable output of a system designed by corporate conglomerates that put margin ahead of your child’s spine.

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, the teenagers with the whistles don't move. They aren't trained to move. In fact, as documented in public reviews of Urban Air locations in Southlake and San Antonio, some employees are reportedly instructed by management to NOT call 911. At the Manginello Law Firm, we have spent 25 years representing…

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 aftermath of an injury at a commercial jump park or a neighbor's backyard in Live Oak, you are likely hearing the same defensive talking points: "You signed a waiver," "The risks are inherent," or "It was a freak accident." We are here to tell you that what happened to your…

"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 you to believe it is. Texas law, including the landmark Munoz v. II Jaz decision, provides several pathways to hold these facilities accountable. Third, the evidence of what happened to your child is disappearing right now. Surveillance DVRs in commercial parks often overwrite in as little as seven to thirty…

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 idea. We would have never put our baby boy on a trampoline if we would have known." We are Attorney911, The Manginello Law Firm. We represent families who find themselves in the trauma bay of University Hospital in San Antonio or Texas Children’s, watching a surgeon explain what happens when…
