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. If you are reading this from a hospital bedside or your living…

"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.

Second: that waiver you signed is not the absolute wall they want you to believe it is.

The Complete Parent’s Guide to Trampoline Park Injuries in Sachse, Texas "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 Kaitlin "Kati" Hill, a mother whose three-year-old son Colton suffered a broken femur and a grueling recovery in a body cast after a trampoline incident.

At the Altitude Trampoline Park on West Campbell Road in Richardson, just a few minutes from the University of Texas at Dallas campus, a Saturday afternoon feels like a rite of passage for families. The parking lot is full, the air is thick with the scent of pizza, and the sound of hundreds of children catching air is deafening. But for many parents in Richardson, that afternoon of "family fun" ends with a sound that Kaitlin Hill described to ABC News in words we hear all too often: "The worst scream that you could ever have heard from a child." Her son Colton was three years old when a heavier jumper double-bounced him, snapping his femur—the strongest bone in the human body. As he lay in a body cast for months, his family was left with the same realization that hits every parent in the trauma bay at Children's Medical Center Dallas or Medical City Plano: "We had no idea." If your child was injured at a trampoline park in Richardson, or on a backyard trampoline in neighborhoods like Richardson Heights or Canyon Creek, you are likely hearing the same thing from insurance adjusters: "You signed the waiver." They want you to believe that a digital signature on a kiosk at the front desk ended your rights before your child even stepped onto the court. They are wrong. Our firm, led by Ralph Manginello with over 25 years of catastrophic injury experience, was built for exactly this fight. We don't…

One Bad Landing in Princeton: The Reality of Trampoline Injuries It happens in the space of a single breath. You are at the Urban Air in McKinney or the brand-new Sky Zone at Preston Ridge in Frisco, celebrating a birthday on a Saturday afternoon. You see your child on the court, laughing, mid-jump. Then, you hear it—a sound that overrides the loud music and the shouting of hundreds of other children. It is what Texas mother Kati Hill once described to ABC News as "the worst scream that you could ever have heard from a child." In Princeton, as neighborhoods like Arcadia Ridge and Brookside continue to expand, the backyard trampoline has become a staple of the North Texas landscape. Whether it is a Jumpking from a local big-box store or a premium Springfree model, these devices are marketed as tools for "safe family fun." But the data we track at Attorney911 tells a different story. Nationally, the Consumer Product Safety Commission (CPSC) reports over 300,000 trampoline-related emergency room visits every year. Many of these victims are children under the age of six, a demographic the American Academy of Pediatrics (AAP) has explicitly warned against using trampolines since 1999. In fact, the AAP has updated its guidance twice—once in 2012 and again in 2019—reiterating that trampolines do not belong in home environments and carry substantial risks even in supervised commercial parks. When a Princeton family experiences a catastrophic injury—a fractured femur, a Salter-Harris growth plate injury, or a life-altering cervical…
