"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 words, told to ABC News by Kaitlin Hill after her three-year-old son Colton suffered a broken femur at a trampoline park, resonate with every parent who has ever stood in a trauma bay. For families in Royse City, the drive along I-30 to a nearby adventure park is supposed to end with tired, happy children—not with a life-altering orthopedic emergency. We understand that you had no idea. We know you would never have let your child onto that court if you had known the physics involved. At Attorney911, we’ve spent more than 25 years holding corporate defendants accountable, and we see the pattern that the industry tries to hide behind kiosk waivers and loud music. Whether your injury happened at the Urban Air in Rockwall, a backyard Jumpking in a Royse City neighborhood, or a school event within Royse City ISD, your family deserves more than an insurance company’s scripted apology. You deserve a legal team that has memorized ASTM F2970, that manages multi-million dollar catastrophic cases, and that knows exactly how to dismantle the "paper shield" the park forced you to sign. The Reality of Trampoline Injuries in Royse City Every year in the United States, roughly 300,000 people visit the emergency room because of trampoline-related accidents. In a growing community like Royse City, where youth sports and active…

One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park in Richardson. While you were at a birthday party watching your child laugh, the double-bounce happened in two seconds. Your child was airborne, then they weren't. Today, you're standing in a hospital room at Children’s Medical Center Dallas or the pediatric trauma unit at Medical City Plano, watching a surgeon explain what happens when a growth plate is destroyed at age nine. If your child was injured at the Altitude Trampoline Park on Campbell Road in Richardson, or a nearby Urban Air in Garland or McKinney, you likely signed an iPad waiver at the kiosk twenty minutes before the paramedics arrived. The park manager might have told you that the waiver ends your claim. They hit you with the "Assumption of Risk" reflex before the ambulance even cleared the parking lot. We’re here to tell you they're wrong. For 25+ years, Attorney911 has fought for catastrophic injury victims across Richardson and the DFW metroplex. Ralph Manginello has spent his career making corporate defendants pay, from the BP Texas City refinery litigation to current $10 million lawsuits against major institutions. Our associate attorney, Lupe Peña, used to sit on the other side of the table—defending trampoline parks and recreational businesses against injury claims. He knows exactly which Richardson waiver clauses are full of holes and which insurance adjusters are using the "Friendly Adjuster Call" tactic to trick you into a quick, cheap settlement.

One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park. At the Urban Air and Altitude parks serving families in Renner, a child can go from a birthday party celebration to a trauma bay at Children’s Medical Center Plano in under thirty seconds. It happens because a parent signed a waiver at a kiosk twenty minutes earlier, believing the marketing that these facilities are "safe family fun." We know the truth. For over twenty-five years, Ralph Manginello and our team at Attorney911 have stood with families across Dallas County when corporate negligence shatters a child’s future. We have seen what happens when the Saturday afternoon rush at a park near Renner collides with a business model that cuts staff to protect margins. We represent families who have heard the sound of a tibia snapping over the loud music of a "Glow Night." We represent the parents sitting at a hospital bedside tonight, wondering if the piece of paper they signed ended their right to hold the park accountable. It didn’t. That waiver isn't a wall; it's noise. In Renner and across Texas, we use a specific, aggressive litigation architecture to pierce those waivers and the multi-layered corporate shells that hide the big insurance towers. Whether your child was injured by a double-bounce on a crowded court, a harness failure on a climbing wall, or a hidden defect in a backyard Jumpking or Skywalker trampoline, we are built for this fight. The Reality of…

One bounce. One bad landing. One broken neck. At a trampoline park near the intersection of US-75 and the President George Bush Turnpike, a seven-year-old came off a court on a stretcher last Saturday. His parents had signed the waiver at the kiosk twenty minutes earlier. They were told it was just a formality—a digital "check-in" to let their child play at a birthday party. Now, they are sitting in a waiting room at Children’s Health Specialty Center Plano, watching a specialist explain why their child may never walk again. We have seen this story unfold too many times in Plano. We have spent over 25 years fighting these exact battles for families in Collin County and across the state of Texas. When your life changes in a split second on a trampoline mat, the park's management will not be your ally. They have been trained by corporate risk teams to minimize your injury, hide their surveillance video, and point to the piece of paper you signed. We are here to tell you that the waiver is not a wall. It is a business tactic designed to make you give up. At Attorney911, led by founding partner Ralph Manginello and associate attorney Lupe Peña, we don’t give up. We have litigated against some of the largest corporations in the world, including BP and Walmart. We bring that same Fortune 500-level aggression to every case we handle in Plano.

"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 were the words of Kati Hill, a mother whose three-year-old son, Colton, suffered a broken femur at a trampoline park. Kati’s words, shared over 240,000 times, echo through the living rooms of Josephine and the hospital waiting rooms of Hunt County every weekend. Here in Josephine, we see families searching for a way to let their children burn off energy during the humid Texas summers or after a long week of school. You likely did what every other parent does: you signed the iPad at the kiosk because the line was long, you paid your admission, and you handed your child a pair of grip socks. You didn't expect that fifteen minutes later, your life would be measured by surgical schedules and physical therapy appointments. At Attorney911, led by Ralph Manginello with 25+ years of experience in catastrophic injury law, we are telling you what the park manager won't: what happened to your child wasn't a freak accident. It was the predictable result of a business model that prioritizes throughput and margin over ASTM F2970 safety standards. Whether your injury happened at an Urban Air in McKinney, a Sky Zone in Frisco, or an Altitude in Richardson—parks that serve families right here in Josephine—the corporate playbook used against you is the same. We know that playbook because our team includes…

At the Sky Zone in Frisco, specifically the Preston Ridge location near the intersection of Preston Road and Warren Parkway, a seven-year-old came off a court on a stretcher last year. His parents had signed the waiver at the kiosk twenty minutes earlier, assuming that because the facility was packed with Frisco ISD families, the safety protocols must be as high as the admission price. They were wrong. One bounce, one bad landing, and one broken neck are all it takes to change a Frisco family’s life forever. For over twenty-five years, Ralph Manginello has been fighting for injury victims against corporate giants like BP, Walmart, and Amazon. Now, we bring that same relentless energy to holding trampoline parks in Frisco and throughout North Texas accountable for the business decisions that maim children. What happened to your child wasn’t a "freak accident." It was the predictable output of a system designed to maximize throughput at the expense of safety. The American Academy of Pediatrics (AAP) has been warning since 1999 that trampolines do not belong in recreational centers or homes. Yet, in Frisco neighborhoods from Stonebriar to Phillips Creek Ranch, backyard trampolines are a staple, and the local indoor parks are booked solid for birthday parties every Saturday. We know the industry standards like ASTM F2970 for commercial courts and ASTM F381 for home equipment because we’ve spent our careers studying the ways corporate defendants cut corners to hit margin targets. When your eight-year-old comes off a court with 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, the mother of three-year-old Colton, telling ABC News about the day a trampoline park shattered her son’s femur. Her warning was shared 240,000 times on social media. We read it. We suspect you are reading this because you have heard that same scream, perhaps at an Urban Air or a Sky Zone here in Dallas. One bounce. One bad landing. One life-altering injury. That is the reality of the trampoline park industry in North Texas. Whether you were at a birthday party at the Urban Air near NorthPark Center, a team event at the Altitude off the Dallasside of the President George Bush Turnpike, or a Saturday jump session at the Sky Zone in Irving, the system remains the same. You signed a waiver at a kiosk while your child pulled at your arm, eager to jump. You handed over your credit card and received a pair of grip socks. Twenty minutes later, your family’s life changed forever. We are Attorney911.

We have gone head-to-head with some of the largest corporations in the world, including BP, Walmart, and Amazon.

"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 words, spoken to ABC News by a mother named Kati Hill after her three-year-old son Colton suffered a broken femur at a trampoline park, resonate with every family in Wylie that has lived through a similar nightmare. One moment, your child is at a birthday party at a park near State Highway 78 or over in McKinney; the next, you are in a quiet ambulance heading toward Children's Medical Center, wondering how a "supervised" facility could allow your child's life to change in a single bounce. We are Attorney911, led by Managing Partner Ralph Manginello. For over 25 years, our firm has stood at the bedside of families whose lives were upended by catastrophic negligence. We have gone toe-to-toe with Fortune 500 corporations like BP and Walmart, and we bring that same relentless weight to the trampoline industry. If your child was injured at a commercial park or on a defective backyard trampoline in Wylie, you don't need a lawyer who "handles accidents." You need a team that has memorized ASTM F2970, that knows exactly which clauses in an Urban Air or Sky Zone waiver are void under Texas law, and that includes a former insurance defense attorney, Lupe Peña, who used to write the very arguments these parks now use to deny your claim. The trampoline park industry in…

The Parent’s Guide to Trampoline Park and Backyard Injuries in Weston, Texas One Bounce Can Change Everything for a City of Weston Family Standing at the observation rail on a Saturday afternoon at an Urban Air or Sky Zone near the City of Weston, you hear a rhythmic thumping that sounds like childhood itself. It is a sound of laughter, energy, and freedom. But as we have learned over twenty-five years of catastrophic injury practice, that rhythm can be shattered in two seconds. There is a specific sound that replaces it—one that parents never forget. As Kaitlin "Kati" Hill told ABC News after her three-year-old son Colton broke his femur in a body cast, it was "the worst scream that you could ever have heard from a child." If your child was injured at a trampoline park serving the City of Weston or on a residential trampoline in a Collin County backyard, the nightmare usually begins with that sound. It continues in the trauma bay at Children's Medical Center Plano or the emergency room at McKinney Methodist. You are told your daughter has a Salter-Harris Type II fracture of the distal tibia or that your son’s concussion was actually a traumatic brain injury. Then, before the cast is even dry, the trampoline park's manager hands you a clipboard or their insurance adjuster calls with a "friendly check-in." They want you to believe that the waiver you signed at the kiosk ended your case. They want you to believe that because…

"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 accident shattered her three-year-old son Colton’s femur. She ended her public warning to other families with five words that we hear in our offices every single week: "We had no idea." If you are reading this in a hospital waiting room or at your kitchen table in Van Alstyne while your child sleeps in a room nearby, we know exactly what you’re feeling. You feel the weight of a signature you gave at a kiosk twenty minutes before the world changed. You feel the guilt of letting them jump. You feel the exhaustion of a long drive from an emergency room in McKinney or Dallas back to Grayson County. We are here to tell you two things that the trampoline park’s manager and their insurance adjuster never will. First: this was not your fault. Second: that waiver you signed is not the absolute wall they want you to believe it is. At Attorney911, led by Ralph Manginello with over 25 years of experience in catastrophic injury litigation, we represent families in Van Alstyne and across Texas who have been victimized by an industry that prioritizes profit margins over pediatric safety.
