"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 "Kati" Hill, a mother whose account of her three-year-old son’s broken femur was shared a quarter of a million times on social media. It is a scream we have heard variations of for over twenty-five years. It is a scream that echoes through the quiet suburban streets of Town of Double Oak when a backyard playdate goes wrong, and it is the same scream that pierces the loud, neon-lit atmosphere of trampoline parks across Denton County. In Town of Double Oak, life often centers around family, large backyards, and local recreation. Whether your children are jumping on a backyard Skywalker or Springfree trampoline near Cedarcrest Lane or attending a birthday party at an Urban Air or Sky Zone near Lewisville or Flower Mound, the belief is always the same: that the equipment is safe, the staff is trained, and the risks are "inherent." We are here to tell you that what happened to your child was not an accident. It was the predictable output of a system that…

"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. Her warning post was shared 240,000 times. We read it. So did every parent of every child who has been hurt at a trampoline park since. For families in the Town of DISH, that scream isn't just a headline—it is the reality of a Saturday afternoon gone wrong at a park in Denton, Frisco, or Lewisville. Whether your child was injured at an Urban Air in the DFW metroplex or on a backyard Jumpking in a Town of DISH neighborhood, you aren't just dealing with an "accident." You're dealing with the predictable output of a professional recreation industry that has put margin ahead of your child's safety. One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park. At facilities serving the Town of DISH area, children are being airborne, then launched in ways their developing bodies cannot control. You may have…

"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 Kati Hill described the moment her three-year-old son Colton’s life changed at a foam-pit-and-trampoline facility. Her warning, shared more than 240,000 times on social media, ends with a phrase we hear in nearly every intake call at our firm: "We had no idea." If you are reading this in a waiting room at Cook Children’s in Prosper or near the trauma bay at Children’s Medical Center in Dallas because your child was injured at a facility near Town of Cross Roads, we want you to know three things immediately. First, this 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 did not consent to the park’s failure to follow safety standards. Second, the "temporary" injury you are looking at might have lifelong orthopedic or neurological consequences that the park’s insurance adjuster is already trying to minimize. Third, the evidence that will prove what actually happened—the surveillance video and the digital logs—starts overwriting…

The double-bounce happened in two seconds. You were watching from the observation rail at the trampoline park in Denton County, just a short drive from Town of Corral City, and then your world shifted. One moment, your child was airborne, laughing; the next, they were on the mat, and you heard what Texas mother Kati Hill once described to ABC News as "the worst scream that you could ever have heard from a child." We have seen this scene play out across North Texas too many times. What happens in the next seven days will determine whether your family receives the justice is deserves or is silenced by a kiosk waiver. At Attorney911, we know that when a eight-year-old comes off a court in Town of Corral City with a comminuted femoral shaft fracture, they don't just need a lawyer.

We bringing that same level of federal court experience and relentless pressure to the trampoline industry. We are launching our dedicated…

On any given Saturday afternoon, families from the Town of Copper Canyon travel just a few miles south or east to the massive entertainment hubs in Southlake, Denton, or Frisco. You might be at the Urban Air in Southlake—the flagship location where the entire franchise began—or perhaps the Altitude in Fort Worth Keller. You signed the waiver at the kiosk because the line was long and your children were vibrating with excitement. You handed them their grip socks, told them to have fun, and found a seat at the observation rail. Then, the scream happens. As Kaitlin "Kati" Hill told ABC News after her son Colton’s femur was shattered at a park, it is "the worst scream that you could ever have heard from a child." In that split second, your life in the Town of Copper Canyon changes. The park manager approaches not with a medical kit or an ambulance on speed dial, but with a clipboard and a "guest error" form. You are told the injury was an "inherent risk." You are reminded that you signed a waiver. At the emergency room at Cook Children’s or a trauma bay in Denton, the surgeon explains that your child has…

"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 Kati Hill described the moment her three-year-old’s life changed at a North Texas trampoline park. As parents in the Town of Bartonville, we understand that sound represents every mother’s and father’s worst nightmare. You take your family to a place like Urban Air or Sky Zone near the Town of Bartonville to have fun, to let the kids burn off energy on a hot Texas afternoon, and you believe—because the marketing tells you so—that the environment is safe. But then the double-bounce happens in two seconds. Your child is launched with force multiplied by up to four times their own weight. The landing is off-axis. The bone breaks clean through the growth plate. And while you are standing over your child in a trauma bay, the park’s risk management team is already working to protect their margin, not your family. At Attorney911, led by Ralph Manginello, we have spent over 25 years making corporate defendants accountable for putting profit ahead of safety. Since 1998, we have litigated against…

"Employees are specifically instructed by management to NOT call 911... staff have been told by management to down-play injuries." These were the words written by a mother on Tripadvisor about the original Urban Air Adventure Park right here in Southlake. Her ten-year-old daughter had stepped from a padded walkway onto an active trampoline, shattering her ankle. Instead of a medical response, the parent reported that her child sat for forty-five minutes without aid while the facility focused on managing its own liability. One bounce. One bad landing. One broken bone. That is all it takes at a trampoline park in Southlake. Whether your child was injured at the Urban Air on Southlake Boulevard, a backyard Jumpking in a Southlake master-planned neighborhood, or a school field trip destination elsewhere in Tarrant County, you are currently standing where thousands of parents have stood before: at a hospital bedside, struggling with questions that the park's insurance company is already being paid to avoid answering. At Attorney911, led by managing partner Ralph Manginello with over 25 years of experience, we have built our practice around making corporate defendants pay for the consequences of their business decisions. Your child's injury in Southlake was not a…

One bounce. One bad landing. One broken neck. That is all it takes for a family’s life to change forever at a trampoline park. At a facility in Fort Worth, a seven-year-old child came off a court on a stretcher while the operation’s manager handed the parents a clipboard instead of calling 911. We have seen this pattern too many times. We know the terror of the parent standing at a hospital gurney in a Fort Worth trauma bay, watching a surgeon explain that a growth plate has been destroyed. We represent families who hear that "worst scream you could ever hear from a child," as Kati Hill told ABC News after her three-year-old son Colton suffered a broken femur at a park. Her warning was shared 240,000 times because it resonates with the fear every parent feels when the fun stops and the sirens start. If your child was injured at a trampoline park or on a backyard trampoline in Fort Worth, what you do in the next 7 days will determine whether your case survives. The trampoline industry is a multi-million-dollar machine designed to shield itself from accountability. From the headquarters of Urban Air in Grapevine and Altitude…

"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’s life changed at a "toddler time" session. She told ABC News that despite the marketing, she had no idea of the risk. We hear these stories every day at our firm. From the suburban backyards of The Tribute and Austin Waters in City of The Colony to the packed courts of the commercial trampoline parks along the Sam Rayburn Tollway, the "worst scream" is a sound we are dedicated to answering with accountability. What happened to your child in City of The Colony wasn't an accident. It was the predictable output of a system designed to prioritize throughput and margin over pediatric safety. Whether the double-bounce happened at a Launch in Lewisville, an Urban Air in Frisco, or a Sky Zone in Irving, the legal architecture of the case is the same. The American Academy of Pediatrics (AAP) has been warning parents since 1999 that trampolines don't belong at home. In 2012 and 2019, they reaffirmed that recreational…

"Employees are specifically instructed by management to NOT call 911 ... staff have never received any safety training and there is no safety plan ... staff have been told by management to down-play injuries." These words were not written by a lawyer in a courtroom; they were written by a parent in a public review of the Urban Air park right here in Southlake after her daughter suffered a broken ankle. It is a sentiment we hear echoed in hospital waiting rooms and trauma bays across Tarrant County. One bounce. One bad landing. One life altered forever. At the trampoline parks serving Southlake, a Saturday afternoon birthday party can transition from laughter to a catastrophic medical emergency in less than two seconds. While your child is being rushed to a pediatric trauma center like Cook Children’s in Fort Worth or Children’s Medical Center Dallas, the park’s risk management team is already working. They are relying on the digital signature you gave at the kiosk and the teenaged "court monitors" they hired at minimum wage to shield them from accountability. We are The Manginello Law Firm—Attorney911. We represent families, we represent children, and we represent the parent standing at a hospital…
