"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 describing to ABC News the moment her three-year-old son, Colton, suffered a broken femur at a trampoline park. His thigh bone, the strongest bone in the human body, snapped because an older, heavier child landed on the same trampoline bed. Kati’s warning has been shared over 240,000 times on social media. She ended her message with five words that haunt every parent in Richwood who ever signed a kiosk waiver: "We had no idea." We have spent over 25 years representing families who had no idea. We represent parents in Richwood who are currently sitting at a hospital bedside, watching a surgeon explain what happens when a growth plate is destroyed at age nine. We speak to mothers and fathers who feel a crushing sense of guilt for letting their children jump, and we tell them the same thing every time: This is not your fault. It was never an accident. It was the predictable output of a system designed to prioritize profit margins over your…

"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 trampoline park. That scream is the sound of a system failing a family in Pearland. It is the sound of a business model that prioritizes throughput and quarterly margins over the safety of the children jumping on the courts. At Attorney911, led by Ralph Manginello with over 25 years of experience, we have heard that scream through the case files of hundreds of families. We know that when a child is whisked away to a Level 1 pediatric trauma center like Texas Children’s Hospital or Children’s Memorial Hermann in a body cast, it wasn't a "freak accident." It was the predictable result of an operator choosing to ignore the safety standards they helped write. If your child was injured at a trampoline park in Pearland, or if you are dealing with a catastrophic fracture or head injury from a backyard trampoline in Brazoria County, you are likely standing at a hospital bedside right now,…

#"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 Kati Hill, the mother of three-year-old Colton, describing the moment a family outing at a trampoline park turned into a nightmare. Her son Colton spent months in a body cast because a heavier jumper was allowed on the same trampoline bed. For families in Oyster Creek, these stories often feel far away until the moment they aren't—until a birthday party at a park in nearby Pearland or Sugar Land ends with an ambulance ride to a Level 1 pediatric trauma center like Texas Children’s Hospital in the Houston Medical Center. We have spent more than twenty-five years standing at the bedside of families just like yours. We are Attorney911, and our founder, Ralph Manginello, has spent his career holding corporate giants accountable.

One bounce. One bad landing. That’s all it takes for a Saturday afternoon at a trampoline park to turn into a lifetime of medical monitoring and reconstructive surgery. In Manvel, families often head north to Pearland or into the Houston metro to visit parks like Urban Air, Sky Zone, or Cosmic Air. You walk into the lobby, and the music is loud, the lights are bright, and the line for the kiosk is long. You’re prompted to click through a series of screens—a "Participation Agreement" that the teenagers at the front desk describe as a simple "waiver." You sign your name, you pay for the wristbands, and your child runs onto the court. Within twenty minutes, your life changes. Kaitlin Hill, a mother known to many as Kati, described the moment her three-year-old son Colton was injured in a way that haunts every parent who hears it. She told ABC News that when his feet hit the mat, "almost instantly his knees buckled down, and he just let out the worst scream that you could ever have heard from a child." Colton spent the next several months in a body cast because his femur—the strongest bone in the human body—had…

"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 about the moment a trampoline park shattered her son’s femur. Her warning post was shared 240,000 times because every parent recognizes that scream. We recognize it because we represent the families who live it. In City of Liverpool, a weekend trip to a trampoline park in the Greater Houston area is supposed to be a safe way for children to burn off energy. But for many Brazoria County families, it ends in the trauma bay at Texas Children’s Hospital or UTMB. The industry wants you to believe these injuries are "freak accidents" or "inherent risks." We know better. We have spent over 25 years proving that what happened to your child was the predictable output of a business decision. Attorney911 was built for this fight. Managing Partner Ralph Manginello brings more than two decades of courtroom experience, including high-stakes litigation against Fortune 500 giants like BP after the Texas City refinery explosion.

One bounce. One bad landing. One broken neck. That is all it takes for a family in Lake Jackson to find their lives permanently altered at an indoor trampoline park. At a birthday party in a facility serving Lake Jackson, a seven-year-old comes off a court on a stretcher. His parent had signed the waiver at the kiosk twenty minutes earlier, believing the marketing that promised a safe environment for "toddler time." Today, that child is in a trauma bay at a Level 1 pediatric center in the Houston metro area, and the facility manager is looking for a way to say the child "jumped wrong." We know that story because we have spent twenty-five years hearing it. If your child was hurt at a trampoline park or on a neighbor's backyard equipment in Lake Jackson, you are likely feeling a crushing mix of terror, anger, and a deep, unearned sense of guilt. You might think the paper you signed at the front desk ended your case before it began. We are here to tell you that the waiver is not the shield the park wants you to believe it is. In Texas, the law protects children, even when a…

A Saturday afternoon in the City of Freeport usually means a trip to the coast or a gathered crowd for a youth soccer match at the municipal parks. But for many families in Brazoria County, it also means a drive up Highway 288 toward one of the massive indoor trampoline parks serving the City of Freeport area. You walk into a building filled with primary colors, the smell of pepperoni pizza, and the rhythmic thud-thud-thud of hundreds of children becoming airborne. You sign a waiver on a digital kiosk in twelve seconds. You hand your child a neon wristband. And you believe, because the marketing told you so, that the environment is "safe family fun." Then the double-bounce happens. One moment, your son is jumping on a bed he thinks is his own. The next, a larger teenager or an adult lands on that same mat, transferring thousands of Newtons of kinetic energy into your child’s frame. The physics are brutal: at a 3:1 weight ratio, a child’s launch force is multiplied by up to four times. The scream that follows is what Kaitlin Hill told ABC News was "the worst scream that you could ever have heard from 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 Kaitlin "Kati" Hill, a mother from right here in Texas, described to ABC News the moment her three-year-old son Colton’s life changed at a trampoline park. Her warning post was shared 240,000 times because every parent in the City of Danbury knows that feeling—the split second between a Saturday afternoon of laughter and a lifetime of orthopedic monitoring. Colton didn’t just fall; he was launched by the energy of another jumper, a mechanism the industry calls a "double-bounce," resulting in a broken femur and a body cast that lasted for months. At the Manginello Law Firm, we’ve spent over 25 years representing families who, like Kati, felt compelled to say: "We had no idea." If you are reading this in a hospital room at a Level 1 pediatric trauma center like Texas Children’s Hospital or Children’s Memorial Hermann after an accident in the City of Danbury, you need to know one thing immediately: This was not an accident. It was the predictable output of a business decision. Whether your…

"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 Hill described the sound that changed her family’s life to ABC News. Her three-year-old son, Colton, was in the "Toddler Time" zone at a trampoline park when a larger child landed on the same bed. His femur—the strongest bone in the human body—snapped. In Clute, we understand that sound represents the moment family fun turns into a medical nightmare. Whether your child was injured on an open court at a park near Lake Jackson or fell from a weather-degraded backyard trampoline in a neighborhood off Highway 288, that scream is the starting point for a system of corporate negligence that we have spent twenty-five years dismantling. We are Attorney911, and we do not view your child’s injury as an accident. We view it as the predictable output of a business decision. For over two decades, Ralph Manginello and our legal team have taken on multinatonal corporations, from the BP Texas City refinery litigation to our current $10 million lawsuit against the University of Houston for exercise-induced rhabdomyolysis…

Brookside Village Trampoline Injury Law: The Complete Guide for Families One moment, your child is laughing at a birthday party near Brookside Village.

Whether you are visiting the Urban Air in nearby Pearland or have a Jumpking sitting in your own backyard in Brazoria County, you trust that the equipment is safe.
