One bounce. One bad landing. One broken neck. That is all it takes at a trampoline park. At the facilities serving families from Village of The Hills, a seven-year-old child could come off a court on a stretcher while their parents are still standing at the kiosk where they signed a waiver twenty minutes earlier. The double-bounce happens in two seconds. Your child is airborne, launched by a force they cannot control, and then they land in a trauma bay at a Level 1 pediatric center like Dell Children's Medical Center in Austin. For 25+ years, Ralph Manginello and our team at Attorney911 have fought for catastrophic injury victims across Village of The Hills and the state of Texas. We have gone toe-to-toe with Fortune 500 corporations like BP, Walmart, and Amazon. The parent conglomerates behind national trampoline park chains, such as Sky Zone, Inc. (backed by Palladium Equity Partners) and Unleashed Brands (the owner of Urban Air), hire massive corporate-defense firms to shield their assets. That does not intimidate us. We have already won those battles. If your child was injured at a trampoline park near Village of The Hills, what you do in the next 7 days will determine whether your case survives. Most personal injury firms handle these as simple "slip and fall" cases. We don't. We built our practice to dismantle the specific systemic negligence that defines this industry. We cite ASTM F2970 from memory. We know that the court monitor on duty was likely 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 Kati Hill describing the moment her three-year-old son Colton’s femur snapped during a "Toddler Time" session at a trampoline park. Hill told ABC News, "We had no idea. We would have never put our baby boy on a trampoline if we had known." If you are a parent in Village of San Leanna standing at a bedside at Dell Children’s Medical Center in Austin, watching your child in a body cast or waiting for a neurology consult, you are now living Kati Hill’s nightmare. You are likely being told by a park manager or an insurance adjuster that you signed a waiver and therefore have no rights. We are here to tell you that is a lie. The team at Attorney911, led by Managing Partner Ralph Manginello, has spent over 25 years making multi-billion-dollar corporations like BP, Walmart, and Amazon account for the damage they do. Along with associate attorney Lupe Peña—who previously defended insurance companies and recreational facilities from the other side of the table—we know that the piece of paper you signed at the kiosk is not a wall. It is a business tactic designed to make you go away. We don’t go away. We have seen what happens when the trampoline industry’s self-written safety standards are ignored to hit a margin target. We have recovered multi-million…

Imagine a sunny Saturday morning in the Village of Point Venture. Families are packing cars for a day on Lake Travis, but for dozens of other households in the Austin metro area, the day ends not with a sunset on the water, but in the trauma bay at Dell Children’s Medical Center. We have seen this transition from "family fun" to "medical catastrophe" happen in seconds. When a child is launched by a double-bounce at a Sky Zone or a teenager falls from a climbing wall at an Urban Air, the aftermath is a blur of sirens, surgical consults, and a high-pressure stack of "sign-in" forms that the park will later claim were ironclad legal waivers. "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’s femur snapped at a trampoline park. Her story, shared over 240,000 times on social media, isn’t just a warning; it is the documented reality of an industry that operates with a "safety floor" they wrote themselves. At the Manginello Law Firm, also known as Attorney911, we don't just handle personal injury cases; we dismantle corporate shields. Since 1998, our founder Ralph Manginello has spent over 25 years making multi-billion-dollar corporations like BP, Walmart, and Amazon account for the damage they cause. We are bringing that same industrial-scale litigation experience to families in the Village…

"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." These are the words of Kaitlin "Kati" Hill, a mother who watched her three-year-old son, Colton, suffer a broken femur at a trampoline park. Her warning, shared a quarter of a million times on social media, ended with a haunting admission: "We had no idea." If you are reading this from a hospital waiting room at Dell Children's Medical Center or a quiet living room in the Village of Briarcliff, you likely find yourself in that same position. You thought you were giving your child an afternoon of "safe family fun" at an Urban Air in Bee Cave or the Sky Zone in Cedar Park. You signed the required electronic document on a kiosk, assuming it was a standard sign-in sheet. Then, in one second, everything changed. One bounce. One bad landing. One life-altering injury. We are Attorney911, and we have spent over 25 years representing families in the Village of Briarcliff and across Texas who have been devastated by catastrophic injuries. We know that what happened to your child wasn't a "freak accident." It was the predictable output of a multi-billion-dollar system that puts profit margins ahead of pediatric safety. Whether the injury happened at a commercial park or on a defective backyard trampoline in a Village of Briarcliff neighborhood, the road to recovery starts with understanding that the law…

At the Altitude Trampoline Park on South Interstate 35 in Round Rock, or the nearby Sky Zone in Cedar Park and Urban Air Adventure Parks serving Williamson County, a Saturday afternoon can change a family’s narrative in less than two seconds. For most parents in Round Rock, these facilities are seen as the "Sports Capital of Texas" equivalent of indoor recreation—a safe place for birthday parties, off-season conditioning for youth football, or a summer escape from the 100-degree Central Texas heat. But when your child hits the mat and you hear what Texas mother Kati Hill described to ABC News as "the worst scream that you could ever have heard from a child," the illusion of safety vanishes. You are no longer a parent at a birthday party; you are a parent at the bedside in a trauma bay at Dell Children’s Medical Center, watching a surgeon explain that your eight-year-old has sustained a Salter-Harris Type II fracture—a growth plate injury that may not grow straight for the next decade. At Attorney911, we believe you deserve to know the truth that the kiosk in the lobby won't tell you: A trampoline injury is never an accident. It is a business decision that went wrong. Whether your child was double-bounced by an adult the park failed to separate, fell from a harness at an Urban Air because an attendant failed to check the clips, or developed dark-brown urine and kidney failure 48 hours after a two-hour "all-day jump" pass in a…

Mustang Ridge Trampoline Park Injury Attorneys Attorney911 of Houston TX 25+ Years Defeating Sky Zone and Urban Air Waivers via Former Defense Insider Lupe Peña and Federal Litigator Ralph Manginello Anchored by Cosmic Jump $11.485M and Damion Collins $15.6M Urban Air Arbitration Mastery Holding Palladium Equity and Unleashed Brands Seidler Accountable for Pediatric TBI Spinal Cord Injury Salter-Harris Fractures and Rhabdomyolysis under ASTM F2970 EN ISO 23659:2022 and AAP Standards for Altitude DEFY Launch and Backyard Jumpking Skywalker Springfree Defects Specialist Covering Sky Rider Strangulation Foam Pit Entrapment and Double-Bounce Accidents with Hablamos Español Delfingen Bilingual Defense and No Fee Unless We Win 1-888-ATTY-911

In Mustang Ridge, families often travel along SH-130 or US-183 toward Austin or San Marcos seeking "safe family fun" at one of the region’s massive trampoline and adventure parks. You take your children to a birthday party at an Urban Air or an afternoon jump at Altitude, trusting that the teenage staff and the corporate branding provide a safe environment for your child to burn off energy. But in a single second, the laughter stops. A double-bounce launch, a harness that wasn't clipped correctly, or an under-filled foam pit converts a Saturday afternoon into a life-altering medical emergency. At Attorney911, led by managing partner Ralph Manginello with over 25 years of courtroom experience, we’ve seen the aftermath of these business decisions. We’ve stood in trauma bays with parents from Mustang Ridge while surgeons explain what happens when a growth plate is destroyed at age nine. We’ve written the demand letters that make insurance adjusters realize they aren't dealing with a generalist firm, but with a team that knows ASTM F2970 and the physics of trampoline injuries better than the park’s own risk managers. If your child was injured at a trampoline park or on a backyard trampoline in Mustang Ridge, you may feel an overwhelming sense of guilt or confusion. You signed the waiver. You let them jump. You might think your case is over before it begins. We are here to tell you that what happened to your child wasn't an accident—it was the predictable output of a corporate…

The Parent's Guide to Trampoline Park and Backyard Injuries in Jollyville, Texas One Bad Landing: The Reality for Jollyville Families Imagine a typical Saturday in Jollyville. You might be celebrating a birthday party at one of the adventure parks near Research Forest Heritage or taking the kids for a treat after a game at a local youth soccer field. In those moments, you want your children to have fun, burn off energy, and make memories. You don't expect to leave the park in an ambulance heading toward the nearest pediatric trauma center. But for many families in Jollyville and across Williamson County, that is exactly what happens. Over the last 25 years, our attorneys at Attorney911 have seen the life-altering consequences of a single bad bounce. We’ve stood in hospital rooms at Dell Children’s and other local facilities, watching parents realize that the "safe family fun" they were promised was a business model built on risk. As Kaitlin "Kati" Hill famously told ABC News regarding her three-year-old son Colton’s 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." Colton’s injury wasn't a freak accident. It was the predictable output of a system that ignores 25 years of medical warnings. Since 1999, the American Academy of Pediatrics (AAP) has warned that trampolines simply do not belong in a recreational or home setting for children. Yet, as Jollyville has grown,…

The Complete Guide to Trampoline Injury Law in Elgin: Protecting Your Family’s Rights "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 were the words of Kaitlin "Kati" Hill, a mother whose three-year-old son Colton suffered a broken femur and was forced into a body cast after an afternoon at a trampoline park. As she told ABC News, "We had no idea. We would have never put our baby boy on a trampoline if we had known."

At Attorney911, we know that scream. We represent families in Elgin and throughout Texas who are living through the nightmare Kati Hill described.

Kaitlin Hill, a mother known as Kati to her friends, took her three-year-old son Colton to a trampoline park during a session marketed for the youngest jumpers. Like many families in West Lake Hills, she believed that a facility advertising "Toddler Time" had been engineered for the safety of children his size. But a larger child—older and significantly heavier—rebounded on the same trampoline mat at the wrong instant. The energy transfer from the heavier jumper launched Colton with a force his small frame was never meant to decelerate. His femur, the strongest bone in the human body, snapped. We have read Kati’s description of that moment many times; she calls it the worst scream you could ever hear from a child. Colton spent months in a body cast. When Kati posted her warning to other parents, it was shared a quarter-million times. Her conclusion was simple and haunting: "We had no idea." At Attorney911, we share this story because we represent families in West Lake Hills who are currently living that same nightmare. We represent parents sitting in the waiting rooms of Dell Children’s Medical Center, watching as surgeons explain what a Salter-Harris growth plate fracture means for their child’s next decade of development. We write this because the commercial trampoline park industry and backyard manufacturers have known about these risks for more than twenty-five years, yet they continue to prioritize profit margins over the orthopedic and neurological safety of children in City of West Lake Hills. If your family…

Seeking Justice After a Trampoline Injury in the City of Sunset Valley "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 during what was supposed to be a safe "Toddler Time" session at a park. Her warning, shared a quarter of a million times, ends with a sentiment we hear from families in the City of Sunset Valley every single week: "We had no idea." If your child was injured at a trampoline park near the City of Sunset Valley, or if you were hurt on a defective backyard trampoline in your own neighborhood, you are likely standing where Kati Hill stood. You are at the bedside in a trauma bay—perhaps at Dell Children’s Medical Center—watching your child deal with a Salter-Harris growth plate fracture or a traumatic brain injury. You are probably replaying the moment you signed that electronic waiver on the iPad kiosk, wondering if you signed away your family's future. We are Attorney911. Our firm is led by Ralph Manginello, who brings over 25 years of courtroom experience to every case we take. We are based in Texas, with offices in Houston, Austin, and Beaumont, but our knowledge of trampoline injury law is sought after nationwide. We know the City of Sunset Valley. We know the families…
