“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, suffered a broken femur at a trampoline park. Colton spent the next several weeks in a body cast that reached from his waist to his ankles. On Facebook, Kati’s warning to other parents was shared over 240,000 times. She spoke for thousands of families in the City of Angleton and across Brazoria County when she finished her post with five devastating words: “We had no idea.”

At Attorney911, we know exactly what Kati meant. We represent families who walked into a facility labeled for “safety” and “family fun” only to leave in an ambulance. We represent parents in Angleton who are told by a teenage “court monitor” that they have no case because they signed a waiver on an iPad. We are here to tell you that the waiver isn’t a wall—it’s just a piece of paper designed to protect corporate margins at the expense of your child’s health.

Whether your child was hurt at an Urban Air, a Sky Zone, an Altitude, or on a backyard trampoline in an Angleton neighborhood, we’ve built our firm to handle this exact fight. Ralph Manginello brings more than 25 years of experience in catastrophic injury litigation to your side. Since 1998, he has gone head-to-head with some of the largest corporations in the world, including BP, Walmart, Amazon, and FedEx. We aren’t intimidated by the private equity firms that now own the major trampoline chains. We’ve already beaten their playbook.

When your child arrives at a Level 1 pediatric trauma center like Texas Children’s Hospital in Houston, the medical bills start mounting before the first surgery is over. You don’t need a generalist lawyer who “handles accidents.” You need an attorney who can quote ASTM F2970 safety provisions from memory and an associate like Lupe Peña, who used to defend these very same recreational companies. He knows which waiver clauses work and which ones are full of holes. Together, we use that insider knowledge to make sure the park pays every dime your child deserves.

Why Trampoline Injuries in Angleton Aren’t “Accidents”

There’s a common myth that a broken bone at a jump park is just a “freak accident.” The data says otherwise. According to a landmark 2024 study published in the journal Pediatrics by Teague et al., there were more than 13,000 documented injuries across 8.4 million jumper-hours. The study revealed that foam pits and high-performance jumping areas carry an injury rate of nearly 2 incidents for every 1,000 hours of use. In a busy park on a Saturday afternoon near Angleton, that means an injury isn’t just possible—it’s statistically inevitable.

The American Academy of Pediatrics (AAP) has been sounding the alarm since 1999. Their official policy, reaffirmed in 2012 and 2019, is clear: trampolines should not be used for recreational purposes at home or in parks. Every manufacturer like Jumpking, Skywalker, or Springfree knows this. Every chain like Sky Zone or Urban Air knows this. They choose to ignore 25 years of medical consensus because selling “jump time” is more profitable than keeping kids safe.

The Brazoria County Evidence Clock

If your child was injured in Angleton, you are already in a race against time.

  1. Surveillance Video: Most park DVR systems are set to overwrite footage in as little as 7 to 30 days. If we don’t send a spoliation letter immediately, the visual proof of the park’s negligence is gone forever.
  2. Incident Reports: Parks often “revise” or “finalize” incident reports hours after you leave. We subpoena the metadata to show what the staff actually wrote before the corporate office told them to change it.
  3. Waiver Versions: The text you signed on that iPad can be “updated” by the SaaS provider on a 72-hour cycle. We use forensic tools to capture exactly what was on the screen when you were at the counter.

We don’t wait weeks to investigate. Our spoliation letters go out within 24 hours of your call. While the park is trying to downplay your child’s injury, we’re already preserving the evidence needed to win.

The Science of the Double-Bounce

The most common way children in Angleton get hurt at places like Urban Air or Altitude is the “double-bounce.” The physics are brutal. When a 200-pound adult lands on a trampoline mat at the same time a 60-pound child is pushing off, the energy transfer multiplies the child’s launch force by up to four times.

The child isn’t jumping anymore; they’ve become a projectile.

ASTM F2970, the safety standard written by the trampoline industry itself, requires parks to keep jumpers of different sizes separated. When a park allows “all-age” jumping during peak hours to maximize ticket sales, they are knowingly creating a catapult for your toddler. We bring in biomechanical engineers to model these impacts. We prove that the park knew the danger, had the rules to stop it, and chose the money instead.

The Texas Advantage: Defeating the Waiver in Angleton

If you’re reading this at 11 PM in a hospital room, you’re probably worried about the waiver you signed. You gave your name, your child’s birthday, and you tapped “I Agree.”

In Texas, that piece of paper is not an automatic shield for the park. Under the Munoz v. II Jaz Inc. ruling, Texas courts have held for over 30 years that a parent’s signature generally cannot waive a minor child’s personal injury claim. Even though you signed, your child’s right to sue survives.

At Attorney911, we attack waivers on four fronts simultaneously:

  • Gross Negligence: In Texas, no waiver can release a company from gross negligence. If the park knew a mat was torn or an attendant wasn’t watching and let your child jump anyway, the waiver fails.
  • Conspicuousness: The Dresser Industries v. Page Petroleum doctrine requires that release language be bold, large, and specifically mention “negligence.” If it was buried in small print on a screen you had to scroll through, it may be legally void.
  • Signer Authority: If a grandparent, aunt, or family friend signed for your child during a birthday party, Texas Family Code § 153.073 says they had no authority to bind your child.
  • Bilingual Defect: If your primary language is Spanish and the park only gave you an English waiver without a translation, the Delfingen doctrine allows us to argue that no valid contract was ever formed.

One of our attorneys, Lupe Peña, spent years defending these cases for insurance companies. He knows exactly where the “airtight” waivers are leaking. We don’t accept the park’s word that you have no case. We write the demand letters that force them to realize we know more about their waiver than they do.

Catastrophic Injuries We Handle in Angleton and Brazoria County

Trampoline injuries are not “small kid” problems. The forces involved produce injuries that surgeons usually only see in high-speed car wrecks.

Pediatric Femur and Tibia Fractures

A child’s bone is not just a smaller version of an adult bone. Children have growth plates (physes) that are weaker than the surrounding ligaments. A Salter-Harris fracture at age eight can destroy the growth plate, meaning one leg may stop growing or grow at an angle. We work with pediatric orthopedic surgeons to project these costs ten years into the future. A “broken leg” now can mean dozen of surgeries later.

Traumatic Brain Injury (TBI)

Head-first landings into foam pits or collisions with unpadded metal frames cause diffuse axonal injury (DAI). Because a child’s brain is still developing, a TBI can cause academic regression, behavioral shifts, and cognitive decline that doesn’t fully show up until months after the incident. We retain neuropsychologists to establish a baseline and quantify the lifelong educational support your child will need.

Spinal Cord Injury and SCIWORA

In the City of Angleton, we are particularly concerned about SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. A child can land on their head in a foam pit, have a “normal” CT scan in the ER, and then lose feeling in their legs four hours later. The pediatric spine is so flexible that the cord can be stretched and damaged even if the bones don’t break. If the park attendants didn’t call 911 immediately or moved your child incorrectly, they turned a treatable injury into a permanent one.

The Rhabdomyolysis Risk

Texas summers are unforgiving, and indoor trampoline parks often have inadequate HVAC. If your child jumps for two hours straight, gets dehydrated, and develops dark-brown, cola-colored urine the next day, they may be suffering from rhabdomyolysis. This is a medical emergency where muscle tissue breaks down and poisons the kidneys. We currently litigate a $10 million case involving rhabdo. We know the lab tests, we know the doctors, and we know why the park is responsible for not providing hydration protocols.

Who is Really Responsible? (The 5-Layer Stack)

When we file a lawsuit for an Angleton family, we don’t just sue the local LLC. “Urban Air” or “Sky Zone” is a brand, not a single company. We peel back the corporate layers to find the money:

  1. The Operator LLC: The local entity with the lease.
  2. The Franchisee: The owner who often runs multiple locations and has a larger insurance policy.
  3. The Franchisor: Corporate entities like Sky Zone Franchising LLC or UATP Management LLC. We name them because they mandate the training—or lack of it—that caused the injury.
  4. The Parent Company: Sky Zone, Inc. (formerly CircusTrix) or Unleashed Brands. These are owned by massive private equity firms like Palladium Equity Partners and Seidler Equity.
  5. The Manufacturer: If a net tore, a spring snapped, or a climbing wall harness failed, we sue the people who built the product (like Ropes Courses, Inc. or UA Attractions, LLC).

In the Damion Collins case, an arbitrator awarded $15.6 million for a quadriplegic injury. The franchisor was held responsible for 40% of that award because they failed to implement safety changes they knew were necessary. We bring that same “go upstream” strategy to every case in Brazoria County.

Frequently Asked Questions for Angleton Families

Can I sue if I signed a waiver at a park in Angleton?

Yes. As we discussed, Texas law is very protective of children. Under the Munoz and Dresser rulings, your signature as a parent typically does not bar your child’s claim, especially if the park was grossly negligent. If a monitor was on their phone while your child was getting double-bounced, that waiver isn’t worth the screen it was signed on.

How much is my child’s trampoline injury case worth?

Every case is different, but settlements for serious fractures often range from $500,000 to $2 million. Catastrophic spinal or brain injuries can reach over $10 million. We calculate “damages” by looking at the medical bills, future surgeries, the lifelong cost of care (Life Care Plan), and the physical and emotional pain your child has endured.

What should I do if the park’s insurance company calls me?

Don’t answer. Their job is to get you to say something like “my child is feeling better today” or “it was just an accident” so they can use it against you in court. They might even offer a “Med-Pay” check for $3,000. If you deposit that check, you may be signing away your right to a $1 million settlement. Tell them you have an attorney and hang up.

How long do I have to file a lawsuit in Texas?

The standard statute of limitations is two years from the date of the injury. However, for a minor child, the clock is “tolled” until they turn 18. This means they actually have until their 20th birthday to file. But you should never wait. The evidence disappears in days. If you wait two years, the witnesses have moved, the video is erased, and the park has been sold. Call us today.

What if my child was hurt on a neighbor’s trampoline in Angleton?

This falls under the “Attractive Nuisance” doctrine. Texas law holds that if a homeowner has something on their property that is likely to attract children (like a trampoline) and fails to secure it (like leaving the gate unlocked or the ladder on), they can be held liable for injuries to trespassing children. We look at the homeowner’s insurance policy—and their umbrella policy—to find the coverage your child needs.

Making the Deep Pockets Pay

National trampoline chains make hundreds of millions of dollars a year. They hire high-powered defense firms to make you go away. They want you to think this is your fault.

It isn’t.

We’ve seen what happens in the discovery phase of these cases. We’ve seen internal audit reports that show managers knew about broken equipment for months. We’ve read training manuals that tell employees to “not call 911” to avoid bad publicity. We’ve pulled state records like the Sky Zone Tukwila $68,000 citation for safety lapses.

We aren’t just filing a claim; we’re launching a forensic investigation. We pull the park’s daily inspection logs to see if they were just “pencil-whipped” (signed without an actual check). We look at the personnel files of the attendants to see if they were hired last week with only two hours of training. We find the evidence they hope you never see.

Dealing with Insurance Tactic: The “Med-Pay” Trap

Within 48 hours of an injury in Angleton, an adjuster might call you sounding like a friend. They’ll say, “We’re so sorry about what happened. We have a small policy that will cover your $1,500 ER copay right now. We just need you to sign this receipt.”

That “receipt” is almost always a full release of liability. By taking the $1,500, you are ending a case that could be worth $1,500,000. This is a classic tactic used by every major insurer in the recreational industry. We handle the adjusters so you don’t have to. When they call, give them our number: 1-888-ATTY-911.

Your Next Steps: Protecting the Future

If you are a parent in the City of Angleton or anywhere in Brazoria County, and your child is currently recovering from a trampoline-related injury, the most important thing you can do—after getting medical care—is to protect their legal future.

What happened at that park wasn’t an accident. It was the result of a business model that prioritizes throughput over safety. The American Academy of Pediatrics has been warning about this since 1999. ASTM F2970 was written by the industry to establish a floor for safety, and the park you visited likely fell right through it. The waiver at the counter was drafted by corporate lawyers who knew it wouldn’t hold up in a Texas court, but they hoped you wouldn’t hire a lawyer who knew that.

We were built for exactly this fight. Ralph Manginello brings 25 years of federal court and catastrophic injury experience. Lupe Peña brings the defense-side secrets that dismantle the park’s board-room strategies. Our offices in Houston, Austin, and Beaumont are the launch point for a national practice that doesn’t care what the waiver says—we care what the evidence says.

The evidence is disappearing every minute you wait. The DVR is overwriting. The attendants are quitting. The foam pit is being refilled.
