"Sus pies tocaron la colchoneta y, casi al instante, se le doblaron las rodillas y soltó el peor grito que jamás se le podría escuchar a un niño". Esa fue Kaitlin Hill, una madre que pensaba que un parque de trampolines en Texas era un lugar seguro para que jugara su hijo de tres años. Su hijo, Colton, terminó con un yeso en todo el cuerpo durante meses tras sufrir una fractura de fémur durante una sesión de "Toddler Time" (horario para niños pequeños). Su advertencia se ha compartido cientos de miles de veces porque captura la silenciosa comprensión a la que se enfrenta cada padre en la ciudad de El Cenizo al entrar en estas instalaciones: no teníamos ni idea. En Attorney911, dirigidos por Ralph Manginello, con más de 25 años de experiencia en tribunales, sabemos exactamente lo que ocurre en esas instalaciones. Cuando su hijo resulta herido en un parque de trampolines cerca de la ciudad de El Cenizo, el gerente del parque y su compañía de seguros quieren que usted crea que fue un "accidente fortuito". Quieren que crea que la renuncia de responsabilidad (waiver) que firmó en el quiosco puso fin a sus derechos legales antes de que su hijo siquiera pusiera un pie en la pista. Estamos aquí para decirle que están equivocados. Una lesión en un trampolín en la ciudad de El Cenizo casi nunca es un accidente. Es el resultado predecible de una decisión empresarial. En todo Texas, desde el condado de Harris…

At the edge of a trampoline court on a Saturday afternoon in the Greater Austin area, everything feels like a celebration. The music is loud, the air is thick with the scent of concession-stand pizza, and for the families in the Village of Webberville who drive into the city for a birthday party, the environment feels engineered for joy. But for us, as attorneys who have spent over 25 years standing in the wake of these celebrations, we know a different reality. We have heard what Kati Hill, a mother whose life changed in a heartbeat, described to ABC News as "the worst scream that you could ever have heard from a child." We know that in the time it takes for a three-year-old’s knees to buckle under the weight of a double-bounce, a family’s world in the Village of Webberville can be shattered. What happened to your child at a trampoline park wasn't an accident. It was the predictable, documented output of a business model that often prioritizes throughput and profit margins over the safety of the children in the Village of Webberville. When you see a 200-pound adult and a 50-pound child on the same interconnected trampoline bed, you aren't looking at "fun"—you are looking at a violation of the industry’s own safety floor, ASTM F2970. We have spent our careers, led by our founding partner Ralph Manginello since 1998, holding corporate giants accountable. Whether it is litigating against the multinational interests involved in the BP Texas City…

"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. We represent these families because we know that a trampoline injury in the Village of Volente is never just an accident—it is the predictable output of a business decision that prioritized margin over the safety of your child. For families in the Village of Volente, an afternoon at a trampoline park or a weekend in a backyard equipped with a Jumpking or Skywalker trampoline is meant to be a release of energy and a source of joy. But the physics of these devices, combined with the systemic negligence of the commercial jump-park industry, transforms these recreational spaces into high-energy trauma vectors. Whether you were at the Sky Zone in Cedar Park near Scottsdale Drive or watching kids on a residential mat near the shores of Lake Travis, the risks are the same. Approximately 1.6% of all pediatric emergency department trauma visits in the United States are now trampoline-related, according to the 2024 American Journal of Roentgenology. We are the Manginello Law Firm, known as Attorney911. Our founder, Ralph Manginello, has spent over…

Village of The Hills Trampoline Park Injury Attorney Attorney911 25 Year Federal Litigator Ralph Manginello & Former Defense Insider Lupe Peña Defeating Sky Zone Urban Air Bee Cave Waivers via Delfingen & § 153.073 Signer Authority Anchored by Cosmic Jump $11.485M Harris County Verdict Damion Collins $15.6M Urban Air Arbitration & Active UH $10M Rhabdo Litigation ASTM F2970 EN ISO 23659 AAP Standards Mastery For Pediatric TBI Spinal Cord Salter-Harris & Sky Rider Strangulation Cases Suing Unleashed Brands Seidler Equity Palladium Partners Jumpking Springfree Backyard Defects Hablamos Español No Fee 1-888-ATTY-911

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,…
