"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…

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. Her warning has been shared hundreds of thousands of times because it taps into a primal fear shared by every parent in Sachse: the realization that a place advertised for "family fun" can, in a split second, become a place of permanent trauma. At Attorney911, we know that what happened to Colton Hill—and what may have happened to your child in Sachse—was not a freak accident. It was the predictable output of a systemic failure. Whether the injury occurred at an Urban Air in the surrounding DFW area, a local backyard trampoline along Highway 78, or a community event in Woodbridge, the legal architecture remains the same. We are not just a personal injury firm. We are a team led by Ralph Manginello, who brings over 25 years of courtroom…

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…

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…

"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…

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…

"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,…

"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…

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…

"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.

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.
