"It’s the worst shout you could ever hear from a child." For Kaitlin Hill, that moment at a trampoline park didn’t just signal a broken bone; it was the start of a nightmare where her three-year-old son Colton ended up in a body cast. In Town of Highland Park, where family life centers on the Highland Park High School "Scots" spirit and elite youth athletics, an afternoon at a local trampoline park is often seen as a standard weekend activity. But at The Manginello Law Firm, we know the truth that many parents in the Park Cities only discover in the trauma bay at Children's Medical Center Dallas: these facilities are often business-driven environments where safety standards are treated as optional suggestions. Whether your child was injured at an Urban Air in Southlake, a Sky Zone in Frisco, or on a premium Springfree trampoline in your own Town of Highland Park backyard, your family deserves more than an insurance adjuster’s "friendly check-in." You need an advocate who has spent over 25 years making corporate giants like BP and Walmart pay for their negligence. Ralph Manginello and our team don't just "handle" personal injury cases; we dismantle the legal shields 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." For Kaitlin Hill, the Texas mother whose story was shared a quarter of a million times, that moment at a trampoline park changed her family’s life forever. For families in the Town of Addison, that scream is the sound of a system failing. Injured at an indoor jump arena or on a backyard trampoline in the Town of Addison? You’ve likely already encountered the first layer of the defense machine. You were handed a clipboard or an iPad. You were told to sign a waiver before your child could enter the court. You were told the park has "industry-leading safety standards." And now, with your child facing a potential lifetime of orthopedic monitoring or a permanent spinal cord injury, the insurance adjuster is calling with a "friendly" check-in, waving that signed piece of paper as if it carries the force of law. It doesn’t. At Attorney911, led by Managing Partner Ralph Manginello with over 25 years of courtroom experience, we know that a trampoline injury in the Town of Addison is…

One bounce. One bad landing. One broken neck. That is all it takes at a Rowlett trampoline park for a family’s life to change forever. We have seen it happen on Saturday afternoons in neighborhoods all over Rockwall County. You were at a birthday party, you were watching your child enjoy themselves, and then you weren't—because the double-bounce happened in two seconds, and your child was airborne. When your seven-year-old comes off a court on a stretcher at a park near Rowlett, you don’t need a lawyer who "handles personal injury cases." You need a legal team that can quote ASTM F2970 Section 10 from memory. You need an attorney who knows that specific court needed a minimum of one attendant per 32 jumpers, and who has spent over 25 years making multi-billion-dollar corporate defendants accountable. That is Ralph Manginello. That is our firm. For more than two decades, we have fought for families in Rowlett and across Texas. We understand the terror of the parent standing at a hospital bedside in a trauma bay, watching a surgeon explain what happens when a growth plate is destroyed at age nine. We built our practice to pierce the corporate shields that…

Kaitlin "Kati" Hill describes the moment in a way that stays with any parent who has ever visited a trampoline park in North Texas. Her three-year-old son, Colton, was jumping during a "Toddler Time" session—a window supposedly designed to keep small children safe from the chaos of older jumpers. But the segregation didn't work. A bigger child landed on the same trampoline bed as Colton, and his femur snapped. Kati later told ABC News it was "the worst scream that you could ever have heard from a child." Colton spent the next several months in a body cast that reached from his chest to his ankles. Kati’s warning post was shared 240,000 times, ending with a phrase we hear across Ovilla and Ellis County every week: "We had no idea." We hear that same sentiment at hospital bedsides when we represent families whose lives were upended in a single bounce. Families in Ovilla often visit the big chains along the I-35E or US-287 corridors—Urban Air in Waxahachie or Mansfield, Altitude in Cedar Hill, or Sky Zone in Irving. You walk through the doors, a teenager hands you an iPad to sign a waiver, and you assume the park has a…

The Parent’s Guide to Trampoline Injury Law in Grand Prairie One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park in Grand Prairie. Your family were likely at a Saturday afternoon birthday party at an Urban Air or a Sky Zone near the I-30 corridor, or perhaps you were in your own backyard in a quiet neighborhood near Joe Pool Lake. You were watching, and then you weren’t—because the double-bounce happened in two seconds. Your child was airborne, and then they were on the mat, letting out what Texas mother Kati Hill described to ABC News as "the worst scream that you could ever have heard from a child." At Attorney911, led by Ralph Manginello with over 25 years of experience, we represent families in Grand Prairie who have had their lives upended by these "business decisions disguised as fun." When your eight-year-old comes off a trampoline park court on a stretcher and the operations manager hands you a clipboard instead of calling 911, you don't need a lawyer who "handles personal injury." You need an attorney who can quote ASTM F2970 Section 10 from memory, who knows that the court needed 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 mother who watched her three-year-old son suffer a broken femur during what was supposed to be a safe afternoon at a trampoline park. She later shared those words with ABC News, and they have become a haunting anthem for thousands of parents across North Texas. In Glenn Heights, where families flock to nearby adventure parks in Waxahachie, Mansfield, and Cedar Hill, that scream is becoming an all-too-common reality. Whether your child was injured during a "Toddler Time" session at a major chain or you were blindsided by a catastrophic collision on a Saturday afternoon, you are likely hearing the same lines from the park’s management. They tell you it was a "freak accident." They point to the iPad you signed at the front desk and tell you that you waived your right to sue. They might even offer to pay your emergency room copay in exchange for a "discretionary" settlement form. We are here to tell you that the park manager and their insurance adjuster are…

Coppell Trampoline Park Injury & Pediatric Catastrophic Injury Attorneys at Attorney911 of Houston TX: 25+ Years Defeating Sky Zone Urban Air Altitude and DEFY Waivers and Holding Corporate Parents Unleashed Brands Seidler Equity and Palladium Equity Accountable for Pediatric TBI Spinal Cord SCIWORA and Salter-Harris Growth Plate Fractures Featuring Our Insider Advantage as Former Recreational-Business Defense Counsel Following the $11.485M Cosmic Jump Verdict and $15.6M Damion Collins Arbitration Success Utilizing ASTM F2970 EN ISO 23659:2022 and AAP Standards for Backyard and Commercial Park Litigation with No Fee Unless We Win Hablamos Español 1-888-ATTY-911

At the trampoline parks serving Coppell and across the North Texas suburbs, a Saturday afternoon can change a family’s life in roughly two seconds. We have seen it happen repeatedly. One moment, a child is celebrating a birthday in a crowded facility off Highway 121 or near the Grapevine Mills area; the next, they are being loaded into an ambulance bound for Children’s Medical Center Dallas or Cook Children’s with an injury that will require years of specialized orthopedic care. If your child was injured at a trampoline park in Coppell, the first thing the facility manager likely did was hand you a clipboard or point to the digital waiver you signed at the kiosk. The park’s insurance adjuster will follow up within 48 hours, sounding concerned and helpful, while subtly trying to get you to agree that the accident was "just one of those things." We are here to tell you that it wasn't. A trampoline injury is almost never a freak accident; it is the predictable output of a business decision to operate below the safety floor established by the industry’s own standards. At Attorney911, led by Ralph Manginello with over 25 years of trial experience, we don’t…

"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 whose son Colton, age three, suffered a broken femur at a trampoline park. Her warning post was shared over 240,000 times, and she ended her account with words that every parent in Combine needs to hear: "We had no idea. We would have never put our baby boy on a trampoline if we would have known." In Combine, and across the Dallas-Fort Worth metroplex, we see families every weekend walking into facilities like Urban Air, Sky Zone, and Altitude. You sign a waiver at a flickering kiosk, pay for a wristband, and assume that "industry standards" are keeping your child safe. But the truth is, a trampoline injury is never just a "freak accident." It is almost always the predictable output of a business decision. Whether it is a park operating at half the required attendant ratio to save on labor costs, or a manufacturer selling a backyard trampoline that the American Academy of Pediatrics (AAP) has warned against since 1999, the responsibility belongs…

"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 Texas, describing for ABC News the moment her three-year-old son Colton’s femur was shattered at a trampoline park. Colton was jumping in a "Toddler Time" session—a window specifically marketed to parents of small children as a safe environment. He spent months in a body cast. His mother’s public warning has been shared more than 240,000 times because it resonates with the private fear of every parent in the City of Wilmer who has ever signed an iPad waiver while a line of excited children waited behind them. "We had no idea," Kati said. "We would have never put our baby boy on a trampoline if we would have known." At the Manginello Law Firm—Attorney911—we believe you shouldn't have to find out the hard way. If you are reading this at a hospital bedside or in your home in the City of Wilmer after a trampoline accident, you need to understand one thing clearly: what happened to your child was not…

Imagine a Saturday afternoon in University Park. Your family is transitioning from a morning soccer match at Curtis Park or perhaps a youth clinic near the SMU campus. You decide to reward the kids with a trip to one of the nearby trampoline parks in North Dallas, Frisco, or Grapevine. You stand at the kiosk, the line behind you is long, and you quickly tap "I agree" on a digital waiver so the kids can start jumping. Twenty minutes later, you hear it—the sound that stops every parent's heart. As Kati Hill told ABC News after her three-year-old son Colton broke his femur at a park, it is "the worst scream that you could ever have heard from a child." In an instant, a fun family outing has turned into a nightmare of sirens, trauma bays at Children’s Medical Center Dallas, and a surgeon explaining what happens when a growth plate is destroyed at age nine. We are Attorney911. Since 1998, Ralph Manginello has fought for catastrophic injury victims against the world’s largest corporations. We didn’t build our firm to handle "slip and falls."
