One bounce. One bad landing. One broken neck. That is all it takes at a commercial trampoline park serving the families of Sandy Point. You were at a birthday party, perhaps at an Urban Air in Pearland or the Sky Zone in near the South Loop. You were watching, and then you weren’t—because the double-bounce happened in two seconds. Your child was airborne, then they weren’t.

At Attorney911, we have spent 25 years standing at hospital bedsides with parents just like you. We have seen what happens when the “fun” of a weekend outing in Brazoria County collides with the cold reality of a multi-million-dollar industry that prioritizes throughput over protection. Since 1998, Ralph Manginello has been fighting for injury victims in the Southern District of Texas, and our firm brings that federal-court-tested aggression to every trampoline injury case we handle.

If your child is in a body cast today or facing a decade of orthopedic surgeries because of a growth plate injury, do not listen to the park’s insurance adjuster. Do not accept their $3,000 “medical payments” check. And most importantly, do not believe that the waiver you signed at a kiosk ended your case.

The Sandy Point Parent’s Guide to Trampoline Park Accountability

Sandy Point families typically route through high-traffic corridors like State Highway 288 or Highway 6 to reach the saturated trampoline park markets in Pearland, Sugar Land, and Webster. In these facilities, thousands of children are airborne every weekend. Every one of them is an insurance policy with a waiver attached. But here in Texas, that piece of paper is not the shield the park believes it is.

We know the industry because our team includes an attorney, Lupe Peña, who used to sit on the other side of the table. He spent years defending recreational businesses and insurance carriers against claims exactly like yours. He helped write the defense strategies. Now, he uses that playbook against them. He knows which Texas waivers are airtight and which ones are full of holes. He speaks Spanish natively and represents our Hablamos Español clients directly—without interpreters, without delays, and without the insurance company using a language gap to settle your case for pennies.

Our firm has recovered multi-million dollar settlements for traumatic brain injury and spinal cord injury victims—the same catastrophic categories a park or defective residential trampoline creates in a single bad landing. We have gone toe-to-toe with Fortune 500 corporations like BP following the Texas City refinery disaster. The parent conglomerates behind national trampoline park chains like Sky Zone, Inc. (formerly CircusTrix) and Unleashed Brands (the parent of Urban Air) do not intimidate us. We have already fought that fight.

Why Your Child’s Injury Was Never an Accident

A trampoline injury is never an accident. It is a business decision that went wrong. The American Academy of Pediatrics (AAP) has been warning parents that trampolines do not belong in a recreational setting since 1999. They reaffirmed this in 2012 and again in 2019. For over a quarter-century, the medical consensus has been total: trampolines maim children.

The industry knew this. That is why they wrote their own safety standard, ASTM F2970. They didn’t wait for a government regulator to tell them what was safe. They drafted the “floor” themselves to prevent lawsuits. When a park in the Sandy Point area violates its own industry standard—by understaffing a court, failing to separate age groups, or letting a foam pit compact until it’s as hard as the concrete beneath it—they are choosing to operate below a standard they helped create.

In Harris County, a jury showed exactly what Texas citizens think of that choice. In the landmark case against Cosmic Jump (Max Menchaca v. Cosmic Jump), a sixteen-year-old fell through a tear in a trampoline slide and struck a concrete floor, suffering a traumatic brain injury. The park had a signed waiver. The jury didn’t care. They found gross negligence and awarded $11.485 million, including $6 million in punitive damages. That is the largest reported jury verdict against a U.S. trampoline park, and it happened right here in our home market. It is exactly the kind of case we are built to handle.

The Evidence Clock: Why the Next 7 Days Are Critical

While you are focused on the trauma bay at a Level 1 pediatric facility like Texas Children’s Hospital or Memorial Hermann, the park’s risk management team is already at work. They aren’t working to help you; they are working to protect the franchise.

The most critical evidence in your case is currently on a timer. Park surveillance DVR systems in Texas are typically set to overwrite in as little as 7 to 30 days. The waiver kiosk database, which contains the metadata of exactly how and when you signed that agreement, may purge on a 72-hour cycle. The attendant who was on his phone instead of watching your daughter may quit or be transferred to another location in Houston or Dallas within the month.

Our spoliation letter goes out within 24 hours of your retention. We demand the preservation of the DVR hard drive, the original (unrevised) incident report, the shift logs, and the specific foam blocks or springs that caused the injury. We do not wait for the park to “happen” to lose the video. We freeze the crime scene immediately.

Call 1-888-ATTY-911. We are available 24/7 because trampoline injuries don’t happen during bank hours—they happen on Friday nights and Saturday afternoons. The consultation is free, and you pay nothing unless we win.

The Mechanisms of Injury: What Really Happens on the Court

Every attraction in a multi-use facility like Urban Air or Altitude has a signature failure mode. We investigate these through the lens of physics and the ASTM F2970 standard.

The Double-Bounce Multiplyer

This is the most common mechanism we see in Sandy Point cases. A 200-pound adult lands on a trampoline bed at the same instant a 60-pound child pushes off. The kinetic energy transfer is not additive—it is multiplicative. The child’s launch force is multiplied by up to 4x. In that moment, the child isn’t jumping; they are being thrown by a catapult. This is a direct violation of weight-separation rules and one-jumper-per-bed requirements.

The Foam Pit Illusion

Foam pits look like clouds. They are often shallow, compacted, and dangerous. When the foam blocks are not rotated and replaced according to the industry schedule, they lose their ability to decelerate a body. A head-first entry into a degraded foam pit leads to cervical hyperflexion and axial compression. This causes SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. A child may have a “normal” CT scan in the ER but be paralyzed six hours later as the cord begins to swell.

Sky Rider and Harness Failures

The move toward “adventure parks” has added indoor zipline-coasters (Sky Rider) and climbing walls to the mix. We have seen a chain-wide pattern of Sky Rider strangulations and falls. In Sugar Land, the Lakhani family’s daughter fell 30 feet because an attendant reportedly failed to attach the fall-protection equipment. When the mode of injury is a 30-foot drop onto concrete, “accidental” is not a word we accept. It is a systemic failure of training and supervision.

The Hidden Rhabdomyolysis Risk

If your child jumps for 90 minutes in a heated indoor park in the Brazoria County humidity, drinks sugary sodas, and comes home with “cola-colored” urine and extreme muscle pain, they may be suffering from exertional rhabdomyolysis. This is the catastrophic breakdown of muscle tissue that poison’s the kidneys.

We currently litigate a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. We know the expert nephrologists, the creatine kinase (CK) trajectories, and the medical-litigation architecture required to prove that the park’s failure to provide hydration and rest intervals caused your child’s organ failure.

The Waiver Architecture: Why “I Signed” Doesn’t Mean “I Lose”

The first thing an insurance adjuster will say when they call your Sandy Point home is, “We have your signed waiver on file.” They say it to make you go away. They want you to think as Kaitlin Hill did: “We had no idea.”

But in Texas, the waiver is a speed bump, not a wall. We attack the waiver on three primary fronts:

  1. The Munoz Doctrine: Texas courts have held in Munoz v. II Jaz Inc. that a parent generally cannot sign away a minor child’s personal cause of action. Your signature may bar your own claims for medical bills, but it cannot legally extinguish your child’s right to be made whole for a lifetime of disability.
  2. The Dresser Fair Notice Standard: Under Dresser Industries v. Page Petroleum, a release must be “conspicuous” and meet the “express negligence” doctrine. If the word NEGILGENCE wasn’t in bold, all-caps, contrasting type, or if it was buried in a scroll-box on a tablet, the waiver may be void as a matter of law.
  3. The Moriel Gross Negligence Carve-Out: In Texas, you cannot waive liability for gross negligence. When we find the park’s internal audit showing the foam pit was too shallow for three months, or the training records showing the attendant had exactly zero hours of safety instruction, the waiver disappears. We use the Moriel standard to unlock punitive damages, making the park pay for its conscious indifference to your child’s safety.

Additionally, under the Delfingen doctrine, if your family’s primary language is Spanish and the park only offered a English-only iPad waiver under pressure (“sign quickly or you lose your time”), the contract itself may never have been formed. Lupe Peña uses this insider knowledge to dismantle those waivers before they can reach a jury.

Who is Really Responsible? The 5-Layer Defendant Stack

Most firms sue the local LLC on the front door. We go upstream. The operator LLC in local shopping centers is often undercapitalized by design. To find the money for a lifetime care plan, we peel back the layers:

  • The Operator LLC: The immediate owner of the Sandy Point-proximate location.
  • The Franchisee: The group that likely owns 5-10 other locations.
  • The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC. They dictate the training and safety standards. If they didn’t enforce those standards, they are on the hook.
  • The Brand Parent: Sky Zone, Inc. or Unleashed Brands. This is where the private equity money—Palladium Equity or Seidler Equity—sits.
  • The Component Manufacturer: If a mat tore (like in Cosmic Jump) or a go-kart surged (like in the Emma Riddle Port St. Lucie fatality), we sue the vendor who built the equipment.

We also discover every insurance layer: primary GL (the $1M floor), umbrella policies ($5M-$25M), and franchisor “additional insured” coverage. The adjuster says the policy is $1 million. We find the tower that reaches $50 million.

Pediatric Life-Care Planning for Sandy Point Families

A broken leg at age nine is not just a broken leg. It is a Salter-Harris fracture of the growth plate. If that cartilage is destroyed, the bone that should have grown for the next nine years may grow crooked or stop growing entirely.

When we represent your child, we don’t just calculate your current hospital bills. We work with Certified Life Care Planners (CLCP) to build a 70-year medical forecast. We account for:

  • Corrective osteotomies and leg-length equalization surgeries.
  • Lifetime orthopedic monitoring.
  • Psychological counseling for PTSD and phobia of physical activity.
  • Academic remediation if the injury was a traumatic brain injury (TBI).
  • Lost earning capacity if the child can no longer pursue certain careers.

We advance every dollar for these experts. You are not just some client; as Chad Harris said, “You are FAMILY to them.” We treat your child’s recovery fund as sacred.

Frequently Asked Questions for Brazoria County Parents

How long do I have to sue a trampoline park in Texas?

In Texas, the statute of limitations for personal injury is generally two years. However, for a minor, that clock is “tolled”—meaning it doesn’t start until they turn eighteen. You have until their 20th birthday to file. BUT, the evidence (surveillance/witnesses) will be gone in 30 days. You must preserve the case now, even if you don’t file today.

What if my child was hurt at a birthday party and someone else signed the waiver?

This is a major “waiver gap.” Under Texas Family Code § 153.073, only a parent or legal conservator has the authority to bind a child. If a neighbor, an aunt, or a party host signed that iPad at Urban Air or Sky Zone, they had no legal authority to sign away your child’s rights. The waiver is a legal nullity as to your child.

Is the “Glow Night” at the jump park more dangerous?

Yes. Litigation across the country has shown that “Glow in the Dark” events with UV blacklights and reduced visibility make it nearly impossible for monitors to see small children in dark corners. Parks often run these events with the same or even lower staffing levels than daytime, which we argue is a gross-negligence business decision.

Should I let the park’s insurance company pay our ER copay?

No. This is the “Med-Pay Trojan Horse.” The adjuster will offer to pay $3,000 for your immediate bills. In exchange, they will ask you to sign a “simple release” or deposit a check with release language on the back. Once you do that, you have legally ended your ability to sue for the $500,000 in future surgeries your child actually needs.

What if the park says they don’t have video of what happened?

We don’t take their word for it. We subpoena the DVR hardware itself and the access logs. If the footage “glitched” at the exact moment of the injury—a pattern seen in the Mathew Knight case in Georgia that led to a $3.5 million verdict—we move for an adverse inference instruction. We tell the jury they should assume the park destroyed that video because it proved the park was at fault.

Your Child’s Recovery Starts With One Phone Call

What happened at that park wasn’t an accident. It was the output of a system that put profit ahead of pediatric safety. The AAP has been warning about this since 1999. ASTM F2970 was written by the industry to establish a safety floor, and the park fell through it. The waiver was drafted to scare you, not to stop you.

Attorney911 was built for this fight. Ralph Manginello brings federal court experience; Lupe Peña brings the insurance defense playbook. Your Sandy Point family deserves an attorney who can quote ASTM F2970 Section 10 from memory while standing in a Houston courtroom.

The clock isn’t running tomorrow. It is running right now. As the DVR overwrites and the incident report gets “revised,” you need numbers on your side. You need 1-888-ATTY-911.

Detailed Breakdown: The Mechanics of a Trampoline Lawsuit

When your family is dealing with the immediate aftermath of an injury in Sandy Point—the medication schedules, the follow-up orthopedic visits at the Pearland clinic, the school absences—the legal process can feel like a secondary burden. Our goal is to handle the legal architecture so you can handle the healing. Here is how we build a trampoline case to withstand a Fortune 500 defense.

1. The 24-Hour Forensic Lockdown

The moment we are retained, we initiate our evidence preservation protocol. We don’t just send a generic letter; we send a 10-section preservation demand that identifies the specific DVR channels, the kiosk database metadata, and the employee shift logs. If the park is part of a national chain like Urban Air, we also serve the franchisor in Tarrant County. This ensures that the evidence doesn’t “disappear” between the local franchisee and the corporate office.

2. Biomechanical Reconstruction

We don’t just argue “the kid was hurt.” We retain biomechanical engineers to reconstruct the energy transfer of the double-bounce that launched your child. We model the force of impact against the ASTM specifications for padding and mat tension. We show the jury that the child wasn’t just jumping—they were subjected to forces their skeletal system was never designed to resist.

3. Corporate Structure Archeology

“Sky Zone” isn’t a company. It’s a stack of LLCs. We identify the local operator, the franchisee holding company, the franchisor, the parent (Sky Zone, Inc.), and the private equity sponsor (Palladium Equity). We pull the Franchise Disclosure Documents (FDDs) to see every other lawsuit the chain has faced in the last five years. If they’ve had 40 Sky Rider strangulations across the country (as reported in the Urban Air pattern), we prove the park had “notice” of the defect. Notice is what defeats waivers and produces punitive damages.

4. The Rhabdo and Compartment Syndrome Workup

For injuries involving muscle breakdown or extreme swelling, our medical litigation expertise is unmatched. We use the same experts and discovery protocols from our active $10 million University of Houston rhabdomyolysis case. We track the creatine kinase (CK) levels and renal function labs from the moment your child entered the Sandy Point-area ER. We build a medical timeline that makes the causation undeniable.

5. Waiver Dismantlement

While the park’s lawyers are relying on the “assumption of risk” defense, we are analyzing the waiver formation. Was it unconscionable? Did it violate the Texas Dresser standard? Was the signer under duress? In North America, the 2025 jurisdictional split has moved in favor of families in many states—and even in Texas, the Munoz rule remains the gold standard for protecting minors.

6. Managing the Insurance Tower

We find the money. We don’t settle for the $1M primary policy if your child has a $10M life-care plan. We access the umbrella layers, the franchisor’s additional-insured coverage, and the manufacturer’s product-liability policy. We use the Stowers doctrine to put the squeeze on insurers: if they refuse a reasonable settlement within the limits, they may becomes liable for the entire verdict, even if it exceeds the policy.

7. Net Recovery Multiplication

Settling the case is only half the battle. We perform medical lien negotiation in-house. We work with hospitals and insurance companies (ERISA, Medicaid, private health) to reduce what you owe them from your settlement proceeds. Our goal is to put the maximum number of dollars into your child’s recovery fund, not into a hospital’s bank account.

A Legacy of Holding Corporate Defendants Accountable

Our managing partner, Ralph Manginello, has spent over two decades in the trenches of Texas litigation. He didn’t start with trampoline parks; he started with refinery explosions, trucking wrecks, and multinational corporate negligence. He brings that Fortune 500-level tactical discipline to every trampoline case.

When you hire Attorney911, you aren’t hiring a generalist. You are hiring a firm that has spent years studying the industry, the medicine, and the specific failure patterns that occur at Urban Air, Sky Zone, and Altitude location. We know the managers, we know the defense firms, and we know exactly how much they are willing to pay to keep these cases away from a Brazoria County jury.

As client Donald Wilcox said, “One company said they would not accept my case. Then I got a call from Manginello… I got a call to come pick up this handsome check.” Other firms turn down trampoline cases because the waiver scares them. We take the cases other firms reject because we know the law better than the park’s lawyers do.

Safety Check: 5 Rules for Sandy Point Parents Before You Go

If you decide to let your children jump, do not trust the park’s court monitors to keep them safe. They are often 17-year-olds with two hours of training who are paid near minimum wage. You are the only safety officer your child has.

  1. Feet First Only: Every head-first entry into a foam pit or onto an airbag is a gamble with a cervical spine. Teach your child that any landing other than feet-first is a “walk-out” violation.
  2. The Nysted Rule: Never let your child jump on a bed with anyone else—especially anyone larger than them. If a monitor doesn’t stop it, you must. That 14x injury ratio is real.
  3. Hydrate and Rest: Do not let your child jump for 90 minutes straight. Enforce a 15-minute water and rest break every half hour. Rhabdo is an exertion injury; pacing is the only prevention.
  4. Harness Confirmation: If your child is on the Sky Rider or a climbing wall, visually confirm the fall-arrest line is attached to the harness yourself. Do not look at the attendant’s face; look at the carabiner. Attendants miss this simple step—and children fall 30 feet because of it.
  5. Listen for the Scream: If you see an injury on the floor—even if it isn’t your child—watch how the park responds. If they discourage a 911 call or fail to provide immediate ice and first aid, leave. That facility is not operated with your child’s safety in mind.

You are Not Alone in This Fight

It’s been a nightmare for families like the Hills’ and the Menchacas’. It’s hard to relive the moment, but families across Sandy Point find the strength to come forward because they feel compelled—as Kati Hill said—to make other parents aware.

If you’re at the hospital now, or if you’re looking at your child in a body cast at home in Brazoria County, know that the system that hurt them is finite. We have read the playbook. We know the attack vectors. And we are ready to stand with you.

We represent families. We represent children. We represent the parent at the trauma-bay bedside watching a surgeon explain what happens when a growth plate is destroyed at age nine. That is who we are.
