"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, that moment at a trampoline park replaced the laughter of a weekend outing with the silence of a body cast and the terror of a long hospital stay. Her son Colton was three years old. He had a broken femur. They had been told the park was safe for toddlers. Like so many families in Plano, they believed the marketing. They signed the kiosk waiver. They handed over their credit card. We hear this story in different forms every week at our firm. Since 1998, Ralph Manginello has stood in the gap for families whose lives changed in one bad landing. We have seen what happens when the adrenaline of a Plano Saturday afternoon turns into a pediatric trauma bay at Children’s Medical Center Plano. We’ve read the demand letters from insurance adjusters who think a $3,000 medical-payment check will make a broken growth plate disappear. It won’t. we’ve spent over 25 years making sure corporate defendants like Sky Zone, Inc., and Unleashed Brands learn that a suburban Plano ZIP code is not a shield for negligence. Our firm is launching its dedicated trampoline injury practice from a foundation of catastrophic personal injury success across Texas. We don’t just "handle" these cases. We dismantle the system that produces them. We’ve gone head-to-head with Fortune 500 giants like BP…

Parker Trampoline Injury Lawyer: The Complete Guide to Protecting Your Family In the quiet, large-lot neighborhoods of Parker, Texas, the backyard trampoline is a staple of suburban childhood. From the equestrian-adjacent estates near Parker Road to the family-oriented communities along FM 2514, many families in zip code 75002 view trampolines as harmless exercise. However, a single bad landing can transform a sunny afternoon into a parent's worst nightmare. At the Manginello Law Firm, we know that for a parent in the trauma bay at Children's Medical Center, the sound of a bone snapping is a memory that never fades. As Kaitlin "Kati" Hill told ABC News after her son Colton suffered a broken femur, "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." At that moment, Kati realized what we have known for twenty-five years: trampoline injuries are not "accidents"—they are the predictable result of an industry that prioritizes throughput and profit over pediatric safety. Whether your child was injured on a residential trampoline in a Parker backyard or at a commercial park in nearby Plano, Frisco, or McKinney, you are now facing a complex legal battle. The park will point to a kiosk waiver you signed in a hurry. The manufacturer will claim you failed to supervise. The insurance company will call you with a "friendly" offer designed to close your file for pennies on the dollar. We represent…

"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." When Kaitlin "Kati" Hill shared those words with ABC News, describing the moment her three-year-old son Colton’s femur snapped at a trampoline park "Toddler Time," she wasn't just telling a story. She was describing a nightmare that parents in Nevada and across Collin County face every weekend. It is a nightmare we have seen play out in trauma bays from Dallas to Houston. Colton spent months in a hip spica body cast. His mother’s Facebook post was shared over 240,000 times because it struck a chord with every parent who had ever signed a kiosk waiver in a rush, handed their child a pair of grip socks, and assumed the facility was built for safety. Kati Hill’s conclusion was five simple, devastating words: "We had no idea." At Attorney911, we believe you deserve to have an idea. If you are reading this from a hospital room at Children’s Medical Center Plano or a rehabilitation facility after a trampoline accident in Nevada, you are likely feeling a crushing mix of terror, anger, and guilt. You signed the waiver. You let them jump. You thought it would be fun. We are here to tell you that none of this is your fault. The guilt belongs to a multi-billion-dollar industry that has known for twenty-five years that these products maim children but continues to…

"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 what happened on a Saturday afternoon that ended in a body cast. Her warning to other parents was shared 240,000 times on social media. We read it, just like thousands of other parents in Murphy did. It resonates because it captures the exact moment a family’s life changes—a moment that happens inside a system designed to prioritize throughput over pediatric safety. In Murphy, we see the results of this system every weekend. Families drive down FM 544 or the President George Bush Turnpike to visit Urban Air in McKinney, Sky Zone in Frisco, or the local Ninja Nation right here in Murphy. On paper, it looks like a birthday party or a quick afternoon of exercise. In reality, it is an environment where the American Academy of Pediatrics (AAP) has issued warnings for twenty-five years, and where the industry operates under voluntary standards that they wrote for themselves. One bounce. One bad landing. One broken neck. That is all it takes. When that moment occurs, the park’s risk management team is already at work before the Robinson Road ambulance arrives. Their goal is to close the file using a kiosk waiver and a $1,500 "medical payments" check. Our goal is the opposite. At Attorney911, led by Ralph Manginello with…

One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park. Imagine a Saturday afternoon at a Sky Zone or Urban Air near the City of Melissa. The parking lot is packed with families who drove in from neighborhoods along Sam Rayburn Tollway and US-75. Inside, the noise is deafening—a mix of music, shouting, and the rhythmic thud of hundreds of bodies hitting polypropylene mats. Your child is out there, laughing, burning off energy. You signed the waiver at the kiosk because the line was long and the software was fast. You believed the park when they marketed "safe family fun." Then, in two seconds, the double-bounce happens. A larger teenager lands on the same trampoline bed just as your seven-year-old is pushing off. The energy transfer multiplies your child’s launch force by up to four times. They are catapulted off-axis, missing the mat and striking the unpadded steel frame. As Kaitlin "Kati" Hill described to ABC News when her three-year-old son Colton’s femur was snapped at a similar facility: "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." Like Kati Hill, most parents in the City of Melissa walk into these facilities thinking they are supervised playgrounds. They are not. They are industrial-scale amusement centers operating under a voluntary safety standard they wrote for themselves. When the injury happens, the park manager hands…

"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 who lived every parent’s nightmare when a trampoline park broke her three-year-old son Colton’s femur. Her warning to other parents was shared 240,000 times. We read it. We’ve heard that scream in the stories of the families we represent. We know that as you read this in McKinney, perhaps from a hospital room at Medical City McKinney or while sitting at your kitchen table near Stonebridge Ranch, you are feeling that same sense of "we had no idea" that Kati Hill described to ABC News. One bounce. One bad landing. One broken neck. That is the timeline of a catastrophic trampoline injury. In the seconds it takes for a child to be launched by a double-bounce energy transfer, a family’s life changes forever. At the Urban Air in McKinney on South Hardin Boulevard, or any of the dozens of parks lining the U.S. 75 corridor through Allen, Plano, and Frisco, thousands of children are airborne every weekend. Every one of them is jumping against twenty-five years of medical warnings from the American Academy of Pediatrics. Every one of them is an insurance policy with a waiver attached. If your child was hurt, the park’s risk management team is already at work. Before the EMS unit even cleared the parking lot on Hardin Blvd, the…

"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 three-year-old son Colton suffered a broken femur at a trampoline park. Her warning, shared more than 240,000 times on social media, resonates with every parent who has stood in a trauma bay in Collin County. In Lucas, where the "country living" lifestyle often includes large backyards with high-end trampolines or trips to the major adventure parks in Frisco, McKinney, and Garland, the risk is not theoretical. It is a documented pediatric trauma category. Whether your child was injured at a commercial facility like Sky Zone or Urban Air, or on a backyard Jumpking or Skywalker trampoline after a neighbor’s child wandered onto your property along FM 1378, what happens in the next 72 hours will determine the rest of your family's life. We are The Manginello Law Firm—Attorney911. Since 1998, Ralph Manginello has fought for catastrophic injury victims, securing multi-million dollar settlements for traumatic brain injuries (TBI), spinal cord injuries (SCI), and wrongful death. Our team includes Lupe Peña, a former insurance defense attorney who used to write the very waiver language these parks now use as a shield. We know how to pierce that shield. We know that in Texas, a signed waiver is not a blank check for gross negligence. In Harris County, a jury awarded $11.485 million against the operator…

One bounce. One bad landing. One broken neck. That is all it takes for a Saturday afternoon at a trampoline park to become a lifetime of medical equipment and trauma bays. For families in Lowry Crossing, these facilities represent a common destination for birthday parties and weekend fun, but beneath the neon lights and loud music lies a systemic architecture of risk. At the Sky Zone or Urban Air locations near Lowry Crossing, parents are handed an iPad and told to "sign in" at a kiosk. What they are actually doing is signing a document drafted by corporate counsel designed to strip away the legal rights of their children before they ever touch a trampoline mat. We have spent more than twenty-five years representing victims of catastrophic injuries. Ralph Manginello founded our firm in 1991 with a commitment to holding multinational corporations accountable, from the BP Texas City refinery litigation to current $10 million lawsuits against major institutions like the University of Houston. When your child is injured in Lowry Crossing, you aren't just fighting a local park operator; you are up against private equity-backed conglomerates like Palladium Equity Partners or Seidler Equity Partners. They have armies of lawyers. We have Ralph Manginello. We have Lupe Peña—an attorney who used to sit on the other side of the table, defending insurance companies and recreational facilities. He knows their playbook because he helped write it. Now, he uses that insider knowledge to dismantle their defenses for our clients. What happened to…

Trampoline Park and Backyard Trampoline Injury Guide for Josephine, Texas Families "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 what happened the day a trampoline park broke her son's femur. In one second, a toddler was in the "Little Jumper" zone at a commercial park, and in the next, he was beginning a journey that required a full body cast and months of agony. If you are reading this from a hospital bedside or your living room in Josephine, searching for answers because your child—or you—sustained a catastrophic injury on a trampoline, we understand the weight on your shoulders. You signed a waiver at a kiosk. You were told it was "safe family fun." Now, you are looking at mounting medical bills, specialized orthopedic consults, and the very real possibility of long-term impairment. At Attorney911, led by Managing Partner Ralph Manginello and our associate attorney Lupe Peña, we represent families in Josephine and across Collin County who have been blindsided by the trampoline industry's business model. We bring over 25 years of courtroom experience, federal court admission, and a structural advantage few other firms possess: Lupe Peña used to defend insurance companies and recreational facilities against these exact claims. He knows the playbook they are using against you right now, and he knows exactly how to dismantle…
