"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 three-year-old son, Colton, suffered a broken femur at a trampoline park. Her Facebook post was shared 240,000 times because it resonates with the nightmare every parent in Highland Village fears when they walk into a birthday party at a local jump center. We represent the families behind those screams. At Attorney911, we know that when your child is hurt at a trampoline park in Highland Village, the pain is compounded by a specific kind of betrayal. You signed the waiver. You believed the "Safety First" signs. You watched the five-minute orientation video. And then, in a fraction of a second—a double-bounce energy transfer or a head-first landing in a compacted foam pit—your family’s life changed. We are not just another personal injury firm that handles "accidents." Since 1998, Ralph Manginello has spent over 25 years making corporate defendants pay for the consequences of their business decisions. We’ve gone head-to-head with Fortune 500 giants like BP, Walmart, and Amazon. We know the parent conglomerates behind…

"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 exact second a trampoline park broke her son’s femur. Her story was shared 240,000 times on social media. For parents in the City of Denton, that story isn't just a viral post—it is a frequent Saturday afternoon reality. At a park like the Urban Air Adventure Park on South Interstate 35E in the City of Denton, or the newer Launch Family Entertainment centers popping up across North Texas, families are sold a vision of "safe, active fun." What the industry rarely discloses is that they are operating under a system engineered to maximize throughput and minimize liability, often at the direct expense of a child’s skeletal integrity. We are The Manginello Law Firm—Attorney911. We represent families in the City of Denton and throughout Texas whose lives have been altered by a single bad bounce. We don't just "handle" personal injury cases. We have spent over 25 years making corporate defendants pay for the predictable outputs of their business decisions. Our…

"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 at a trampoline park. Her story, shared over 240,000 times on social media, resonates with every parent in the City of Corinth who has stood at a hospital bedside in Denton or Dallas. You went for a birthday party. You went to let them burn off energy on a hot North Texas afternoon. You signed the waiver at the kiosk because the line was long and the kids were excited. Then, in two seconds, the double-bounce happened. Or the harness on the climbing wall wasn't clicked. Or your child disappeared beneath the foam blocks in a pit that hadn't been refilled in months. We are The Manginello Law Firm — Attorney911. We represent families in the City of Corinth and across Texas whose lives have been upended by the predictable, preventable output of a multi-billion-dollar industry that puts profit margins ahead of pediatric safety.

"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…

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…

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…

One bounce. One bad landing. One broken neck. That is the timeline of a catastrophic injury at a trampoline park in Lewisville, and for many families, it is a nightmare that begins in the seconds it takes for a court monitor to check their phone. At the Launch Family Entertainment center off the I-35E frontage road in Lewisville, or the nearby Urban Air and Sky Zone locations serving Denton County, thousands of children are airborne every weekend. They are jumping at facilities that market "safe family fun" while operating under a business model that prioritizes throughput and margin over the survival of your child’s growth plates. When your child comes off a court on a stretcher at Medical City Lewisville, and the manager hands you a clipboard instead of calling 911, you are seeing the first layer of a corporate defense system designed to isolate the park from the consequences of its own decisions. We are Attorney911. With over 25 years of experience fighting Fortune 500 corporations, Managing Partner Ralph Manginello has built a firm that doesn’t just handle personal injury cases—we dismantle corporate liability shields. We know that a trampoline injury in Lewisville is never an "accident." It is…

Imagine a Saturday afternoon at an Urban Air or Sky Zone near Carrollton. The music is loud, the courts are at capacity, and dozens of birthday parties are operating simultaneously. You watched your child step onto the court, wearing the required grip socks and a neon wristband, after you tapped "I Agree" on a terminal that dozens of other parents were waiting to use. Within minutes, the atmosphere changed from laughter to what one Texas mother, Kaitlin "Kati" Hill, famously described to ABC News as "the worst scream that you could ever have heard from a child." Her son, Colton, was just three years old when his knees buckled on a trampoline mat during a "Toddler Time" session. It wasn't a freak accident. It was physics. A heavier jumper landed on the same mat, transferring rebound energy that snapped Colton's femur—the strongest bone in the body. Kati later wrote, "We had no idea. We would have never put our baby boy on a trampoline if we had known." We write this guide because parents in Carrollton deserve to have that idea before the ambulance is called. Since 1998, Ralph Manginello and our team at Attorney911 have stood with families across…

"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, describing to ABC News the moment her three-year-old son Colton’s femur—the strongest bone in the body—snapped during a "Toddler Time" session at a trampoline park. Like so many families in the Town of Hebron, Kati had no idea. She would have never put her baby boy on a trampoline if she had known the truth about the industry. We represent families in the Town of Hebron who are living through that same nightmare. We represent parents sitting in trauma-bay bedsides near the Sam Rayburn Tollway, watching a surgeon explain that a growth plate has been destroyed.

"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 how Kati Hill described the moment her three-year-old son Colton’s life changed at a "Toddler Time" trampoline session. Colton suffered a broken femur, requiring a body cast and months of agonizing recovery. His mother’s warning was shared a quarter of a million times on social media, ending with a phrase we hear in nearly every intake call at our Carrollton practice: "We had no idea." If you are a parent in City of Carrollton at the bedside of an injured child right now, we know the weight of that silence. You are likely alternating between terror for your child’s future and a crushing sense of guilt. You signed the waiver at the kiosk near the front door of the Urban Air or the Sky Zone off the President George Bush Turnpike. You handed your child a wristband and watched them run toward the courts. But understand this clearly: what happened to your daughter or son wasn't an accident. It was the predictable output of a system that prioritizes corporate…
