"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 was Kaitlin Hill telling ABC News about the day Colton, her three-year-old, suffered a snapped femur at a trampoline park during a small-child session. It is a scream we have heard too many times in our twenty-five years of catastrophic injury practice. Parents in Aubrey often believe that the "Toddler Time" sessions or the safety netting on a backyard mat are sufficient protections. We know better. Whether it is a Saturday afternoon birthday party at an Urban Air in the DFW metro or a summer evening on a Jumpking in an Aubrey backyard, a trampoline injury is never just an accident. It is the predictable output of a system designed to prioritize profit over pediatric safety. At Attorney911, led by Ralph Manginello, we have spent over two decades making multi-billion-dollar corporations accountable for putting revenue ahead of human lives. From litigating against BP after the Texas City refinery explosion to our current $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure, we know how to dismantle corporate shields. We understand the corporate archeology of parent companies like Sky Zone, Inc., currently backed by Palladium Equity Partners, and Unleashed Brands, the parent of Urban Air now owned by Seidler Equity Partners. If your child was injured in or around Aubrey, you are not just fighting a…

The Essential Argyle Parent’s Guide to Trampoline Injury Accountability The Worst Scream You Will Ever Hear Kaitlin "Kati" Hill was like any other parent in Argyle. She wanted her three-year-old, Colton, to burn off energy on a Saturday afternoon. She took him to a nearby trampoline park for "Toddler Time," a session marketed as a safe sanctuary for small children. But in an instant, the fun ended. A larger child landed on the same trampoline mat as Colton. The physics of energy transfer—what we call a "double-bounce"—multiplied the force of the impact. Colton's femur, the strongest bone in the human body, snapped. Kati described the moment to ABC News in a way that haunts every parent: "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." Colton spent weeks in a body cast. Kati’s warning to other families was shared over 240,000 times on social media. She ended her message with five words that we hear from parents in our office every single week: "We had no idea." If you are reading this while sitting at the bedside of your child in a pediatric trauma ward at Cook Children’s in Fort Worth or Children’s Medical Center in Plano, we want you to know three things immediately. First, this is not your fault. You signed the waiver because the line was long and you trusted the park to follow basic safety standards.…

The Complete Guide to Trampoline Injury Accountability in Sunnyvale, Texas One bounce. That is all it takes. You were likely at a weekend birthday party at an adventure park near Sunnyvale, perhaps at the Urban Air in Mesquite or the Sky Zone off the highway. Or perhaps it was a sunny afternoon in your own backyard in one of Sunnyvale’s quiet neighborhoods, where a trampoline that has sat under the Texas sun for years finally reached its breaking point. The double-bounce happened in two seconds. Your child was airborne, and then they were not. Most parents in Sunnyvale describe the aftermath in the same way. As Kaitlin "Kati" Hill told ABC News after her three-year-old son Colton broke his femur at a park: "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." We have spent more than 25 years standing at the bedsides of families just like yours. At Attorney911, led by our founding partner Ralph Manginello, we have handled catastrophic injury cases since 1998. We have seen the medical bills mount after a trip to Children's Medical Center Dallas. We have seen the insurance adjusters from national chains like Sky Zone and Urban Air call with a "friendly" tone, trying to settle for a fraction of what a child’s spinal cord or growth plate is worth. If you are reading this while your child is in surgery or recovery,…

"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 parks use to hide from accountability. We know the industry safety standards like ASTM F2970 by heart, and we know exactly how to prove that the "waiver" you signed at the kiosk is not the ironclad barrier the park wants you to believe it is. One Bounce and a Lifetime…

"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 never just an accident. It is the predictable output of a business decision. Whether the injury happened at a major chain like Urban Air near the Dallas North Tollway or a Sky Zone in nearby Irving, the mechanism and the negligence follow a pattern we have spent two decades dismantling.…

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 national chains like Sky Zone, Urban Air, and Altitude use to hide from Rowlett families. If your child was injured in Rowlett, what you do in the next 7 days will determine whether your case survives.

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 system in place to keep your child alive. But the truth is more sobering. A trampoline injury is almost never a "freak accident." It is the predictable output of a business model that prioritizes throughput and margin over pediatric safety. At Attorney911, led by Ralph Manginello with over 25 years…

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 minimum of one attendant per 32 jumpers, and who has spent decades making multi-billion-dollar corporate defendants accountable.

"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 not telling you the truth. For over 25 years, Ralph Manginello and the team at Attorney911 have fought for families in Glenn Heights and across the country who have been shattered by corporate negligence. We don’t just "handle" personal injury cases; we build catastrophic-injury architectures designed to pierce the corporate…

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 accept the "inherent risk" excuse. Our team includes former insurance defense attorney Lupe Peña, who used to write the very waivers these parks use to hide from accountability. We know the holes in their paper shields, and we know how to pierce the five-layer corporate stack they use to hide…
