“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, describing the moment a trampoline park visit in North Texas turned into a life-altering disaster. Her son suffered a broken femur that required months in a body cast. Her warning to other families was shared over 240,000 times because it resonated with a terrifying truth that many parents in Piney Point Village don’t realize until they are in an emergency room: we had no idea.

At the Manginello Law Firm, also known as Attorney911, we have spent over 25 years representing families who find themselves in that same state of shock. We have seen the medical records from Texas Children’s Hospital and Memorial Hermann. We have stood with the parents who signed a waiver at a kiosk in seconds, only to be told by a corporate insurance adjuster days later that they have no right to seek justice. In Piney Point Village, where backyard trampolines are common and commercial parks like Urban Air, Sky Zone, and Altitude are a short drive down the Katy Freeway or West Loop, these injuries are not freak accidents. They are the predictable output of a multi-billion-dollar industry that prioritized profit margins over pediatric safety.

If your child was hurt at a trampoline park serving Piney Point Village, or on a defective residential trampoline in a Harris County backyard, you need to understand that the system is built to make you go away. The park’s surveillance video is likely set to be overwritten within 7 to 30 days. The incident report you filled out is already being “revised” by a corporate risk management team. The waiver you signed was drafted by lawyers who hoped you would never learn about a simple truth: in Texas, that waiver is not the absolute shield they want you to believe it is.

We are a firm led by Ralph Manginello, an attorney with more than two decades of trial experience who is admitted to practice in the U.S. District Court for the Southern District of Texas. Our team includes a former insurance defense attorney, Lupe Peña, who used to write the very arguments these parks use to deny claims. We know their playbook because he helped train the adjusters who use it. We are not just another personal injury firm; we are the firm currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure—the exact same muscle and organ breakdown we see in children who are overexerted or crushed at trampoline parks.

Whether your child is facing a Salter-Harris growth plate fracture, a traumatic brain injury, or a life-altering spinal cord injury like SCIWORA, we bring 25 years of catastrophic injury experience to Piney Point Village families. We handle these cases on a contingency fee basis, meaning you pay nothing unless we win. We advance every single cost of the investigation—from biomechanical engineers who reconstruct the energy transfer of a double-bounce to pediatric orthopedic surgeons who project your child’s lifetime of medical needs.

The clock is running on the evidence your case depends on. Call 1-888-ATTY-911 today. Hablamos Español. We represent families in Piney Point Village and across the country.

The Reality of Trampoline Park Safety in Piney Point Village

When families in Piney Point Village head to an indoor adventure park in the Houston metro, they assume that a facility open to the public is regulated by the government. In Texas, that is a dangerous misconception. Texas has no statewide trampoline park safety act. There is no state license required to open a jump park, no mandatory state inspection of the trampoline beds, and no requirement for the operator to report injuries or deaths to any state agency.

The only things regulated in a Texas trampoline park are the “Class B” inflatable rides—like bungee trampolines or inflatable obstacle courses—which fall under the Texas Department of Insurance (TDI) under Texas Occupations Code Chapter 2151. The actual trampoline courts, where the majority of catastrophic breaks and neck injuries occur, are explicitly excluded from state oversight at § 2151.002(1)(C)(iv). This regulatory vacuum means the only thing standing between a child in Piney Point Village and a defective foam pit is the park’s own internal policy.

The industry claims to follow ASTM F2970, which is a voluntary standard they wrote themselves. They created the safety floor, and yet we routinely find that parks are operating beneath even that minimum standard. On a Saturday afternoon near Piney Point Village, you might see one “court monitor” watching sixty jumpers. You might see a 200-pound adult jumping on a section adjacent to a 50-pound child. You might see a foam pit that hasn’t been deep-cleaned or refilled in months. Each of these is a violation of the industry’s own rules.

The Physics of the Double-Bounce and Energy Transfer

One of the most common causes of injury we see in Piney Point Village cases is the double-bounce. This is not just “kid stuff.” It is a violent transfer of kinetic energy. When a heavier jumper lands on a trampoline bed at the same instant a smaller child is pushing off, the bed acts as a catapult. The energy transfer can multiply the child’s launch force by up to four times. The child isn’t jumping anymore; they are being thrown.

Peer-reviewed literature, including the Nysted study in the British Journal of Sports Medicine, confirms that when two people of different weights jump on the same trampoline, the smaller person is 14 times more likely to be injured. Despite this, parks in Harris County continue to market “family jump” times that mix teenagers and toddlers. This is why we see so many comminuted femoral shaft fractures and tibia breaks in children who were doing nothing more than trying to play.

The High Stakes of the Foam Pit

Foam pits at parks serving Piney Point Village look like the safest places in the building. They are often the most dangerous. A foam pit is supposed to absorb energy, but over time, polyurethane foam blocks compress and compact. If the pit is not deep enough—if it doesn’t meet the ASTM-recommended depth of roughly six feet—a jumper entering head-first will bottom out and strike the hard floor beneath.

This is the mechanism behind some of the most devastating outcomes in Section L of our case database, including the death of Ty Thomasson in Arizona and the paralysis of Anthony Seitz in Minnesota. The industry knows these pits are dangerous; that is why many Piney Point Village area parks have begun replacing foam pits with airbags. But if you walk into a facility that still uses a foam pit, you are entering a zone where the risk of a cervical spine injury or a “spinal-cord stroke” is significantly elevated.

In June 2024, the Elle Yona case went viral on TikTok, showing a teen who became a quadriplegic after a backflip into a foam pit caused a vertebral artery dissection—essentially a stroke in the spine. These injuries are often misdiagnosed as panic attacks or muscle strains in the ER. We know different. We know that the pediatric cervical spine is uniquely flexible, making children susceptible to SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. The bones look fine on an X-ray, but the cord is dying.

The Piney Point Village Parent’s Guide to Liability

A common strategy for corporate parks like Sky Zone, DEFY, and Urban Air is to hide behind a complex layer of LLCs to prevent families in Piney Point Village from reaching the real money. When you sue, you aren’t just suing the local building. We uncover the five-layer defendant stack:

  1. The Operator LLC: The entity that signed the lease and hired the local staff. They often have limited insurance.
  2. The Franchisee: The ownership group that may run multiple locations across Harris County.
  3. The Franchisor: Corporate entities like UATP Management or Sky Zone Franchising LLC that set the safety rules and conduct the audits.
  4. The Corporate Parent: Mega-conglomerates like Sky Zone, Inc. (formerly CircusTrix) or Unleashed Brands, often backed by multi-billion-dollar private equity firms like Palladium Equity or Seidler Equity Partners.
  5. The Manufacturer: If a spring failed, a mat tore, or an auto-belay on a climbing wall malfunctioned, the equipment manufacturer is also on the hook.

We identify every layer because the medical bills for a catastrophic injury don’t stop at $1 million. A child in Piney Point Village injured today may need orthopedic monitoring for the next decade. If their growth plate is destroyed by a Salter-Harris fracture, they may face multiple corrective surgeries as they grow. A general personal injury firm might settle for the local park’s policy limits. We go upstream to the franchisor and the private equity sponsor because that is where the resources live to truly provide for a child’s lifetime of care.

The “Paper Shield” — Why Your Waiver Fails in Texas

The question every Piney Point Village parent asks us is: “But I signed a waiver, don’t I lose?”

Our answer is always: not automatically. We attack waivers in Harris County on five distinct fronts:

  1. Gross Negligence: Under Texas law, and specifically the Moriel doctrine, no waiver can release a defendant from gross negligence. If the park knew the equipment was torn or that they were understaffed and they ignored it, the waiver is void.
  2. The Munoz Rule: In Texas, the landmark case Munoz v. II Jaz Inc. established that a parent cannot sign away a minor child’s independent legal right to sue. Your signature might bar your own claims for medical bills you paid, but it does not stop your child from seeking justice for their own pain, suffering, and physical impairment.
  3. Conspicuousness and Fair Notice: In Dresser Industries v. Page Petroleum, the Texas Supreme Court ruled that a waiver must be “conspicuous.” If the release was buried in 20 pages of fine print or wasn’t clearly labeled on the iPad at the Piney Point Village area park, it may be legally unenforceable.
  4. Signer Authority: If a grandparent, an aunt, or even a friend’s parent signed for your child at a birthday party, Texas Family Code § 153.073 says they had no authority. The waiver is a legal nullity.
  5. The Delfingen Doctrine: For the many Spanish-speaking families in the Houston metro area, if a waiver was presented only in English without a translation or a meaningful way to understand it, the contract was never validly formed. Lupe Peña at our firm uses this internal defense playbook to dismantle their arguments.

We don’t get intimidated by the document you clicked “Agree” on. We treat it as the first exhibit in a gross negligence case.

Catastrophic Pediatric Injuries in Harris County

Our firm is uniquely positioned to handle the medicine of trampoline injuries because of our work in complex rhabdomyolysis and traumatic brain injury cases. When your child is hurt near Piney Point Village, the damage is rarely just a “broken bone.”

Salter-Harris Growth Plate Fractures

Because children’s bones are still developing, they contain cartilage-rich areas called growth plates or physes. A fracture that extends into this area is a medical emergency that doesn’t always show its full impact on day one. A child in Piney Point Village who breaks their ankle on a trampoline at age 7 might experience a “growth arrest” years later, leading to one leg being significantly shorter than the other or the bone growing at an angle.

We work with pediatric orthopedic consultants to pull the medical chronology and project these damages. We don’t just ask for today’s bill; we calculate the cost of corrective osteotomies at age 14 and life-care needs for the next 70 years.

Traumatic Brain Injury and the Developing Mind

A 5-foot fall through a torn mat onto concrete, as seen in the $11 million Menchaca case in Houston, can cause a diffuse axonal injury (DAI). This is a shearing of the brain’s fibers that can’t always be seen on a standard CT scan. A child may seem “fine” but start failing in school six months later, or experience drastic mood changes and aggression.

Piney Point Village schools are competitive and demanding. A pediatric brain injury isn’t just a physical wound; it’s an economic loss that affects the child’s entire future earning capacity. Our life-care planners and forensic economists in Piney Point Village cases ensure that the settlement covers the special education, the neuropsychological testing, and the career support a child will need as an adult.

Rhabdomyolysis and Exertional Muscle Death

Trampoline parks are high-heat, high-exertion environments. In Houston’s humidity, a child can jump for 90 minutes straight without proper hydration. When muscles are pushed to the point of rupture, they release myoglobin into the blood, which clogs the kidneys.

If your child has tea-colored urine, extreme muscle pain, or confusion after visiting a park near Piney Point Village, they may have exertional rhabdomyolysis. We are currently litigating a $10 million lawsuit involving this very condition. We know the lab values—the CK levels that exceed 10,000 U/L—and we know how to hold institutions accountable for failing to provide water and rest breaks.

The 24-Hour Evidence Clock in Piney Point Village Cases

The most important work in your case happens in the first 72 hours. While you are focused on your child’s surgery at a Harris County hospital, the park is focused on its defense.

By day 10, the surveillance footage of the incident may be automatically overwritten. By day 30, the “kiosk” records of who signed the waiver can be purged. By day 60, the attendant who wasn’t watching may have quit their minimum-wage job and moved to another state.

When you hire Attorney911, our spoliation and preservation-of-evidence letter goes out within 24 hours. We don’t just ask them to keep the video; we demand the DVR hard drive, the access logs, and the original, unrevised incident reports. We use forensic document examiners to check the metadata and ensure that “Version 1” of the story hasn’t been lawyered into “Version 5.”

We know that in Georgia, a $3.5 million verdict was secured for Mathew Knight because the park’s video “glitched” on four different cameras at the exact moment of the injury. We know how to use that kind of evidence destruction to secure an adverse inference for our Piney Point Village clients.

Why Piney Point Village Families Choose Attorney911

We are not a volume firm. We don’t take every case that walks through the door because we put our full resources into the catastrophic ones. When you call us, you aren’t just a file number. As our client Chad Harris said, “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.”

  • Biomechanical Expertise: We retain the engineers who can prove that the park’s equipment failed the laws of physics, not that your child “fell.”
  • Contingency Representation: We pay for everything until we win. Your child’s recovery fund is protected.

Frequently Asked Questions for Piney Point Village Parents

Q: Can I sue if I signed the waiver on an iPad?
A: Yes. Many Piney Point Village area parks use iPad/kiosk waivers that fail Texas’s fair notice requirements. Furthermore, if the injury was caused by gross negligence—like a torn mat or understaffed courts—the waiver is void under the Moriel ruling. Most importantly, per Munoz, you cannot waive your minor child’s rights.

Q: My kid’s doctor said it was just a “trampoline fracture.” Is that a real thing?
A: It is a colloquial term for a proximal tibial metaphyseal buckle fracture, common in kids under 6 who are double-bounced. The problem is that many “trampoline fractures” involve the growth plate. If it’s a Salter-Harris injury, your child could face a lifetime of deformity. Don’t minimize a “broken leg” until an expert projects the next 10 years of growth.

Q: Why didn’t the park call 911? They said they had to wait for me to decide.
A: Documented reviews of parks like Urban Air Southlake suggest that management may instruct staff NOT to call 911 to avoid negative publicity and create an “official” report. This delay is evidence of gross negligence.

Q: Is my child’s case going to be worth millions of dollars?
A: Catastrophic cases involving TBI, SCI, or permanent growth-plate damage often settle or reach verdicts in the millions. The Cosmic Jump case in Houston reached $11.485 million. The Collins case reached over $15 million. Every case is unique, but we build every Piney Point Village file to maximize value.

Q: How long do I have to file a lawsuit in Texas?
A: The statute of limitations is 2 years from the date of injury. For minors, this is “tolled” until they turn 18, meaning they have until age 20. However, waiting is catastrophic for evidence. If you wait more than a few weeks, the surveillance video and the witnesses are gone.

Q: Do you speak Spanish?
A: Sí. Nuestra abogada Lupe Peña es bilingüe y representa a familias hispanas directamente. El caso Delfingen en Texas protege a las familias si el waiver fue solo en inglés y no lo pudieron entender.
