Town of Hackberry Trampoline Injury Guide: Accountability for Texas Families One moment, your son was launching toward a basketball rim at a park near Town of Hackberry. The next, he let out what Texas mother Kati Hill once described to ABC news as "the worst scream that you could ever have heard from a child." In those two seconds, the trajectory of your family’s life in Town of Hackberry shifted from a Saturday afternoon celebration to the interior of a Level 1 pediatric trauma center like Children’s Medical Center Plano or Dallas. We are Attorney911, and we have spent more than 25 years handling the catastrophic medical and legal fallout of business decisions disguised as accidents.

"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 sustained a broken femur at a trampoline park. Her warning, shared hundreds of thousands of times across social media, ends with a phrase we hear in our offices every week: "We had no idea." If your child was recently injured at a facility in Flower Mound, or if you were hurt on a backyard trampoline while visiting a neighbor in one of our master-planned communities like Bridlewood or Wellington, you likely feel that same sense of shock. You signed a waiver at a kiosk on Long Prairie Road, or you watched your child climb onto a neighbor's Skywalker or Jumpking trampoline, assuming the safety netting and the presence of staff meant the risk was managed. We are The Manginello Law Firm, also known as Attorney911. Our founder, Ralph Manginello, has spent more than 25 years holding corporate defendants and insurance companies accountable for catastrophic injuries. We represent families in Flower Mound and throughout North Texas whose lives have been altered by 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 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.

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."

"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.

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…
