One bounce. One bad landing. One broken neck. For many families in Round Rock, the transition from a Saturday afternoon of laughter to a lifetime of medical equipment happens in less than two seconds. "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 the voice of Kaitlin "Kati" Hill, a mother who watched her three-year-old son Colton suffer a broken femur during what was supposed to be a safe session for small children. Her warning, shared hundreds of thousands of times, echoes the experience of thousands of parents who enter facilities like the Altitude Trampoline Park on the I-35 corridor in Round Rock or the Sky Zone in Cedar Park. They sign the kiosk waiver, they hand their child a wristband, and they believe—because the marketing tells them so—that the environment is engineered for safety. We are The Manginello Law Firm, known to families across Texas as Attorney911. We have spent more than 25 years holding multi-billion-dollar corporations accountable when they prioritize profit over people. From litigating against multinational oil companies in the wake of the BP Texas City refinery explosion to our current $10 million lawsuit against the University of Houston regarding catastrophic rhabdomyolysis and kidney failure, we know how to dismantle corporate defenses. If your child was injured at a trampoline park or on a defective backyard trampoline in Round Rock, you aren't just facing 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 how Kaitlin "Kati" Hill described the moment her three-year-old son, Colton, suffered a broken femur at a trampoline park. Like many parents in the City of Rollingwood, she had no idea that a Saturday afternoon outing could end in a body cast. At the Manginello Law Firm, we hear variations of this story every week. We represent the families who were told it was a "freak accident" but later discovered it was the predictable result of a business decision. Whether your child was injured at an Urban Air in South Austin or Bee Cave, an Altitude in Travis County, or on a backyard Jumpking or Skywalker trampoline in the City of Rollingwood, the reality is the same: the system was built to prioritize margin over your child’s safety. We built Attorney911 for exactly this fight. Ralph Manginello brings over 25 years of courtroom experience, including federal court admission and a history of taking on Fortune 500 giants like BP. Our associate attorney, Lupe Peña, 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.

"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 who watched her three-year-old son suffer a broken femur at a trampoline park. Her warning, shared hundreds of thousands of times across social media, is a nightmare that stays with every parent in Pflugerville who has ever stood at an observation rail watching their child go airborne. If you are reading this from a hospital bedside at Dell Children’s Medical Center or while waiting for an orthopedic specialist in Round Rock or Pflugerville, we know the weight you’re carrying. You signed a digital waiver on a kiosk in a crowded lobby. You were told it was "safe family fun." You were told that trampoline parks are a great way for kids to burn off energy.

"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." Kaitlin "Kati" Hill told ABC News those words after her three-year-old son, Colton, suffered a broken femur at a trampoline park. He spent the following months in a body cast. Like so many families in Mustang Ridge, Kati trusted the facility’s marketing. She believed that "Toddler Time" meant the environment was engineered for her child’s safety. She later admitted the truth that haunts thousands of parents: "We had no idea. We would have never put our baby boy on a trampoline if we would have known." What happened to Colton wasn’t a "freak accident." It wasn’t "bad luck." It was the predictable output of a business model that prioritizes throughput and profit margins over the orthopedic integrity of a child’s developing skeleton. In Mustang Ridge, where families travel north on SH 130 or I-35 to reach the massive adventure parks in Austin or San Marcos, the risk is real, constant, and catastrophic. We are The Manginello Law Firm—Attorney911. Our founder, Ralph Manginello, has spent 25+ years making Fortune 500 corporations and institutional defendants pay for their failures. We’ve gone toe-to-toe with BP after the Texas City refinery explosion and litigated against giants like Walmart and Amazon.

One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park. For many families in Manor, a trip to an indoor jump center across the Travis County line or a weekend afternoon on a backyard trampoline on a lot off Highway 290 feels like harmless fun. You see the bright colors, you hear the music, and you see the laughter. But as trial attorneys who have spent more than 25 years fighting for catastrophic injury victims, we see something else. We see the physics of 1,000 Newtons of force hitting a child’s developing growth plate. We see the 5-layer corporate structure designed to hide the money we know is upstream. And we see the parent at the Dell Children’s Medical Center bedside, holding a signed waiver in one hand and their child’s hand in the other, thinking they have no rights. We are here to tell you that what happened to your child in Manor was not a "freak accident." It was the predictable output of a system that puts margin ahead of pediatric safety. Whether you were at a Sky Zone, an Urban Air, an Altitude, or an independent park near Manor, the rules that were supposed to protect your family were likely written by the industry itself to establish a floor, not a ceiling. At Attorney911, led by managing partner Ralph Manginello, we have made corporate defendants pay for more than two decades. From the BP Texas City refinery litigation to our…

The Complete Guide to Trampoline Park and Backyard Trampoline Injuries in Leander, Texas One Second in Leander. One Bad Landing. One Life Forever Changed. Imagine a Saturday afternoon in Leander. Perhaps you are celebrating a birthday at the Sky Zone in Cedar Park just off Scottsdale Drive, or you’ve finally agreed to let the kids jump on the new Skywalker trampoline in your backyard in Crystal Falls. The sun is out, the kids are laughing, and for a moment, everything feels like perfect suburban fun. Then it happens. It isn't a slow-motion event. It’s a snap. A collision. A scream that stops every other sound in the room. As Kati Hill told ABC News after her three-year-old son Colton broke his femur at a park, it is "the worst scream that you could ever have heard from a child." In that single second, your child isn't just "hurt." They are entering a world of trauma bays, orthopedic surgeries, and a recovery process that might span the next decade of their development. At Attorney911, we know what that moment feels like for a parent. We know the panic of the drive down US-183 toward the nearest pediatric ER. We also know what the trampoline park is doing while you are in that waiting room. Before you have even spoken to a surgeon, the park’s risk management team is already working to protect their margin. They are looking at the waiver you signed at the kiosk. They are checking to see if…

One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park serving City of Lakeway.

A parent signed a waiver at a kiosk, handed their child a wristband, and within twenty minutes, their world changed.

"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 over 240,000 times on social media, resonates with every family in City of Lago Vista who has watched a fun Saturday afternoon turn into a medical nightmare. At the Manginello Law Firm, also known as Attorney911, we’ve spent over 25 years standing at the bedside of families just like yours. We’ve seen the body casts, the wheelchairs on the porch, and the long, quiet drives home from the emergency room. If your child was injured at a facility like the Urban Air in Bee Cave or the Sky Zone in Cedar Park serving City of Lago Vista, the first thing you need to hear is this: it is not your fault. You signed a waiver at a kiosk because the line was long and you wanted your child to have fun. You trusted that a business invitee in City of Lago Vista would be protected by the safety standards the industry wrote for itself. When that system fails, the guilt belongs to the corporate entities that chose margin over monitoring. Our managing partner, Ralph Manginello, has spent nearly three decades making multinational corporations pay for choosing profit over people. From the BP Texas City refinery litigation to our current…

At the Sky Zone in Cedar Park or the Urban Air serving families from the City of Jonestown, the Saturday afternoon rush follows a predictable rhythm. The music is loud, the air conditioning is humming against the central Texas heat, and hundreds of children are airborne. For the parents driving down RM 1431 from the City of Jonestown, the visit is a well-deserved break—a "safe" place for kids to burn energy. But beneath the neon lights and the "Toddler Time" branding, a systemic risk is often ignored until the moment of impact. The mechanism that changes a family’s life in the City of Jonestown doesn't take minutes; it takes milliseconds. A child pushes off a trampoline bed just as an adult lands on the same mat. In the physics of the trampoline industry, this is known as a double-bounce energy transfer. Because the trampoline bed stores and releases elastic potential energy, the heavier jumper acts as a catapult. At a 3:1 weight ratio, a child from the City of Jonestown can be launched with up to four times their normal launch force. In one second, the child is mid-air; in the next, they land with a force their developing musculoskeletal system was never engineered to decelerate. As Kati Hill, the mother of three-year-old Colton, told ABC News after her son’s femur was shattered at a park: "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." Those are the words of Kaitlin "Kati" Hill, a mother who watched her three-year-old son, Colton, suffer a broken femur in a body cast after a visit to a trampoline park. As Kati told ABC News, she had no idea. She would have never put her baby boy on a trampoline if she had known the truth. If you are reading this in City of Elgin, perhaps you are in a similar position. You are sitting at a hospital bedside at a Level 1 trauma center like Dell Children's Medical Center or University Hospital, watching a surgeon explain what happens when a growth plate is destroyed at age nine. You are looking at a stack of medical bills that already exceeds your HSA, and you are remembering the iPad kiosk at the front desk where you were told to "sign quickly so the kids can jump." What happened to your child in City of Elgin wasn't a freak accident. It was the predictable output of a system. At Attorney911, we believe a trampoline injury is never just bad luck—it is almost always the result of a business decision that prioritized margin over safety. We have spent more than 25 years fighting for families in catastrophic injury cases, and we are here to tell you that the waiver you signed is not…
