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…

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 this fight. We include a former insurance defense attorney, Lupe Peña, who used to write the very waiver language these parks rely on. He knows where the holes are because he used to try and patch them. If your family was injured on a trampoline in the City of Hill…

"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. When your child is the one in the body cast, the trampoline park manager will point to the waiver you signed on a kiosk and tell you that there is nothing you can do. They are wrong. For over twenty-five years, Ralph Manginello and our team have held multi-billion-dollar corporations accountable. From the BP Texas City refinery litigation to our active $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure, we know how to dismantle the legal and corporate shields that chains like Sky Zone, Urban Air, and DEFY hide behind. If your child was injured at a trampoline…

"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 mother whose warning about her son Colton’s broken femur at a trampoline park was shared over 240,000 times. We have read those words. We have seen the medical charts that follow them. If you are a parent in the City of Grey Forest reading this at a hospital bedside tonight, we understand the specific, heavy silence of a trauma bay. We represent families in the City of Grey Forest who are facing the life-altering reality of a catastrophic trampoline injury. We know the weight of the questions you’re asking: Is it my fault? Can I sue if I signed that iPad at the kiosk? How am I going to pay for these surgeries? At Attorney911, led by Ralph Manginello with over 25 years of experience, we have spent decades holding massive corporate defendants accountable. We've gone toe-to-toe with Fortune 500 companies like BP, Walmart, and Amazon. The private equity conglomerates backing national chains like Sky Zone, Urban Air, and Altitude don’t intimidate us. We know that in the City of Grey Forest and across Bexar County, these parks are marketed as "safe family fun," but the data tells a different story. In Harris County, just down the road, a jury awarded $11.485 million against a facility called Cosmic Jump after a teenager fell through a torn…

The Parent’s Complete Guide to Trampoline Injury Claims in Fair Oaks Ranch If your child was injured at a trampoline park in the Fair Oaks Ranch area, or if a backyard mishap on a neighborhood trampoline has left your family facing mounting medical bills and a long road to recovery, what you do in the next 72 hours will determine the future of your case. At Attorney911, led by Ralph Manginello, we have spent 25+ years making corporate defendants pay for the catastrophic injuries they cause.

With the former insurance defense perspective of associate attorney Lupe Peña on our side, we know exactly how to dismantle the waiver defense you likely signed at the kiosk.

When your child is hurt, the park’s risk management team is already working to protect their…

"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, telling ABC News what happened the day a trampoline park broke her son's femur. Her warning post was shared 240,000 times. We read it. So did every parent in the City of Elmendorf and across Bexar County who has watched their child walk onto an interconnected trampoline court with a pit of foam or a pressurized airbag at the end of it. Colton spent months in a body cast. Kati Hill famously said, "We had no idea. We would have never put our baby boy on a trampoline if we would have known." At Attorney911, we believe that "no idea" is a failure of the industry, not the parent. You were told it was safe family fun. You were told the attendants were trained. You were told the waiver was just a "sign-in" sheet. None of that is the whole truth. If your child was catastrophically injured at a trampoline park near the City of Elmendorf, or if you were injured while jumping, your family's life changed in one landing. The park's insurance adjuster will call you within 48 hours. They will sound concerned. They will ask to "walk through the events." Don't take that call. Every word you say is being recorded to build a defense that blames you or 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." Those are the words of Kati Hill, a mother who watched her three-year-old son Colton suffer a broken femur during a "Toddler Time" session at a trampoline park. Her story is not a freak accident. It is a predictable outcome.

"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 telling ABC News what happened when a trampoline park broke her three-year-old son’s femur. Her warning to other mothers was shared 240,000 times on social media. We have read those words. We have seen the photos of little Colton in a body cast. And we have heard the same story from families in Cibolo, across Guadalupe County, and throughout Texas. One bounce. One bad landing. One life changed forever. If your child was injured at a trampoline park near Cibolo—perhaps during a weekend outing to the Urban Air in New Braunfels or a birthday party at an Altitude in San Antonio—you are likely sitting at a hospital bedside right now. You are exhausted. You are angry. And you are likely feeling a heavy weight of guilt. We are here to tell you that this is not your fault. You signed a waiver at a kiosk because the line was long and you wanted your child to have fun. You trusted that the park was following the rules. The truth we have uncovered over 25 years of catastrophic injury practice is that trampoline injuries are rarely "accidents." They are the predictable output of business decisions made by corporate giants like Sky Zone, Inc. and Unleashed Brands. At Attorney911, led by our managing partner Ralph Manginello, we don't…
