One bounce. One bad landing. One broken neck. That is all it takes for a family’s life in McGregor to change forever. You were at a birthday party in Waco or driving into Temple for a weekend treat. You watched your child walk onto the court, wristband secured, and you believed—because the marketing told you to—that the environment was safe. Then the double-bounce happened. The scream that followed is something no McGregor parent ever forgets.

At Attorney911, we call this the “Worst Scream” scenario. It is the moment when the physics of a trampoline court meet the fragile biology of a child’s developing body. While the park manager in his branded polo shirt hands you a clipboard instead of calling 911, your child is facing a Salter-Harris growth plate fracture, a traumatic brain injury, or a cervical spine crisis.

We are not just another law firm. Our managing partner, Ralph Manginello, brings over 25 years of experience in catastrophic injury litigation to every case. He is admitted to the Southern District of Texas and has fought Fortune 500 companies in massive litigations like the BP Texas City refinery explosion. Our team includes Lupe Peña, a former insurance defense attorney who spent years on the other side of the table. He knows exactly how trampoline parks in McGregor and Central Texas draft their waivers to scare you away—and he knows exactly how to dismantle them.

If your child was injured at a trampoline park serving the McGregor area, you don’t need a generalist. You need a firm that knows ASTM F2970 Section 10 from memory. You need a firm that currently litigates a $10 million lawsuit involving rhabdomyolysis and acute kidney failure—the same catastrophic muscle breakdown we see in McGregor children who are overworked on jump courts.

Call us at 1-888-ATTY-911. Hablamos Español. Our consultation is free, and we pay for every expert up-front. We don’t just handle cases; we protect McGregor families.

The Reality of Trampoline Injuries in McGregor and Central Texas

McGregor is a town of families, youth sports, and backyard fun. Whether your kids are Bulldogs playing in McGregor ISD or just burning off energy after school, trampolines are everywhere. But there is a massive gap between the “family fun” advertised by chains like Sky Zone, Urban Air, and Altitude and the medical reality found in the trauma bays of McLane Children’s Hospital in Temple.

The American Academy of Pediatrics (AAP) has been clear since 1999: trampolines do not belong at home. They reaffirmed this in 2012 and again in 2019. Despite this, manufacturers like Jumpking, Skywalker, and Springfree continue to fill McGregor backyards with equipment that leads to approximately 300,000 emergency room visits annually across the United States.

When the industry moved from the backyard to the commercial park, the risk didn’t disappear—it multiplied. The 2016 Kasmire study in Pediatrics found that trampoline park injuries are more likely to require hospital admission than those in the backyard. Why? Because McGregor families are dealing with higher heights, interconnected beds, and under-trained teenagers acting as “court monitors.”

The “Toddler Time” Trap in Central Texas

Many parks serving McGregor market specialized “Toddler Time” sessions for children under six. This is a direct violation of the AAP medical consensus and ASTM F381 standards, which explicitly state that children under the age of six should never use trampolines. When a park in the Waco-McGregor corridor brings a three-year-old onto a court, they are choosing margin over medicine.

Imagine a Saturday morning. You drive from McGregor into Waco for a session designed for little ones. The court is packed. Because the park isn’t enforcing age and weight separation required by ASTM F2970, a ten-year-old lands next to your toddler. The Nysted 14x rule kicks in: the smaller jumper is 14 times more likely to be injured. The energy transfer from the heavier jumper launches the smaller child like a catapult. The result isn’t a “freak accident.” It is a biomechanical certainty.

The Global Safety Gap: What McGregor Families Aren’t Told

The U.S. trampoline industry is largely self-regulated. While Europe has adopted EN ISO 23659:2022—a mandatory, binding safety standard for trampoline parks—the United States relies on ASTM F2970-22, a voluntary standard that the industry actually helped write.

In ten states, including New York and New Jersey, this standard has some regulatory teeth. In Texas, we have a massive regulatory gap. The Texas Department of Insurance regulates “Class B” inflatable rides like the bungee trampolines and Sky Rider zip-coasters you see at Urban Air, but it does NOT regulate the main jump decks. This means a McGregor family is left relying on the park’s own internal “Brand Standards”—rules that are often discarded the moment a Waco facility gets busy on a Saturday afternoon.

Ralph Manginello and our firm don’t wait for state regulators to catch up. We treat a violation of ASTM F2970 as a breach of the duty of care. When a court monitor is on their phone instead of enforcing the one-jumper-per-bed rule, that is negligence. When a foam pit is compacted to four inches of clearance instead of the eight required by spec, that is a lawsuit.

Why the Waiver You Signed in Waco Does Not End Your Case

The most common reason McGregor parents don’t call 1-888-ATTY-911 is because they believe the piece of paper they signed at the kiosk is a wall. It is not. It is noise.

Our team, led by Ralph Manginello, uses a five-vector attack to dismantle trampoline waivers:

  1. The Gross Negligence Carve-Out: In Texas, under the Moriel standard, no waiver can release a park from gross negligence. If the park in Waco knew a mat was torn—like the $11.485 million Cosmic Jump case in Houston—and didn’t fix it, the waiver is void.
  2. Parental Indemnity for Minors: Texas law, anchored by the Munoz v. II Jaz Inc. decision, holds that a parent generally cannot sign away a minor child’s personal cause of action. Your child didn’t sign the waiver. Your child didn’t consent to the risk.
  3. The Dresser Fair-Notice Doctrine: Texas courts require waivers to be “conspicuous.” If the release of negligence was buried in a 20-screen iPad flow at a Waco facility while a line of kids was screaming behind you, it fails the “fair notice” test.
  4. Bilingual Formation: The Delfingen Edge: If your family speaks Spanish as a primary language and the McGregor-area park only provided an English waiver on an iPad, we use the Delfingen doctrine to argue that no contract was ever formed.
  5. Scope of Risk: A waiver covers “inherent risks” like an awkward landing. It does not cover the park’s choice to understaff the gym or leave a harness unattached on a climbing wall.

As Lupe Peña will tell you—having built these waivers for the other side in the past—they are designed to discourage you from calling a lawyer. They are not designed to win in a McLennan County courtroom after a child has been paralyzed.

Catastrophic Injury Mechanisms: The Physics of Pain

When we represent a McGregor family, we don’t just say your child was “hurt.” We retain biomechanical engineers to prove how the injury happened. We use medical specificity to ensure the insurance adjuster knows we are ready for trial.

Pediatric Growth Plate Fractures (Salter-Harris)

Children’s bones are not like ours. They have physes—growth plates. A fracture through these plates (Salter-Harris classification) is a silent catastrophe. An eight-year-old child in McGregor might have a leg that stops growing correctly, leading to a measurable limb-length discrepancy by age 14. We don’t just look at the ER bill; we build a Life-Care Plan that accounts for surgical corrections a decade into the future.

SCIWORA: The Invisible Spinal Injury

Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) is a nightmare for parents. A child lands head-first in a compacted foam pit in Temple or Waco. The X-ray is normal. The CT scan is normal. But the child is losing feeling in their legs. This is a pediatric-specific event where the ligaments are more flexible than the cord itself. We hold parks accountable for failing to train staff to recognize these signs immediately.

Rhabdomyolysis: The UH Bridge

Our firm is uniquely positioned to handle rhabdo cases. We are currently litigating a $10 million case against the University of Houston involving rhabdomyolysis and acute kidney failure. We see the same mechanism at trampoline parks: McGregor kids jumping for 90 minutes in a hot Waco facility without hydration. When muscle cells rupture and tea-colored urine appears 48 hours later, you are in a medical emergency. Because we are already litigating this physiology at the highest levels, we have the nephrology and toxicology experts ready to testify today.

Who is Really Responsible? Piercing the 5-Layer Stack

The park in Waco wants you to believe they are just a small local business. They aren’t. We use corporate archeology to pierce the shield:

  • Layer 1: The Operator LLC. The single entity on the lease in McLennan County.
  • Layer 2: The Franchisee. The multi-unit holding company that may own five locations.
  • Layer 3: The Franchisor. Entities like UATP Management LLC (Urban Air) or Sky Zone Franchising LLC. They dictate the training and safety floor.
  • Layer 4: The Brand Parent. Sky Zone, Inc. (formerly Maximus/CircusTrix) or Unleashed Brands. These are multi-million dollar conglomerates.
  • Layer 5: The Private Equity Sponsor. Firms like Palladium Equity Partners or Seidler Equity Partners. They make the cost-cutting decisions that lead to understaffing.

In the Damion Collins v. Urban Air case, the franchisor was hit with 40% of a $15.6 million award. We go upstream to the deep pockets so your child’s recovery fund is fully funded.

The 48-Hour Evidence Clock: Do Not Wait

If you are reading this in McGregor after an injury, the clock is ticking.

  1. The DVR Window: Most parks in the Waco-Temple-McGregor area overwrite their surveillance every 7 to 30 days. If you haven’t sent a formal spoliation letter, the footage of your child’s fall is being deleted right now.
  2. The Incident Report “Step-Up”: Parks often “revise” or “finalize” incident reports days after the accident. The original handwritten notes are the gold. We preserve them.
  3. Kiosk Metadata: The 72-hour purge cycle for kiosk logs can hide the fact that a waiver wasn’t properly executed.

Call 1-888-ATTY-911 within 24 hours. We send our litigation-hold scaffolds immediately upon retention. We don’t just ask for the video; we demand the DVR hard drive, the access logs, and an affidavit from the IT manager.

Frequently Asked Questions for McGregor Parents

Can I sue if I signed the waiver at a Waco or Temple park?

Yes. As we’ve detailed, Texas waivers are highly vulnerable on grounds of gross negligence, conspicuousness, and the Munoz minor-void doctrine. Don’t let a manager tell you that you’ve signed away your rights.

How much is a trampoline park injury settlement worth?

For a pediatric growth plate fracture in Texas, we anchor in the $500K to $2M range. For permanent spinal cord injury, national verdicts and our own data point to the $10M to $25M+ range. Every case is unique, but we build for maximum recovery.

What if my child was injured on a neighbor’s trampoline in McGregor?

This falls under the Attractive Nuisance doctrine. If a neighbor in McGregor left their trampoline ladder down and a child wandered onto it, the homeowner’s policy generally responds—even if the child was technically a trespasser.

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

The standard SOL is two years, but for McGregor minors, the clock is tolled until their 18th birthday. However, the evidence will be dead in 30 days. If you wait until the legal deadline, you won’t have the video evidence to win.

Why won’t the park give me the security footage?

Because they know it shows their negligence. They hope you’ll wait until the DVR overwrites the footage. We don’t wait. Our spoliation letter freezes the media in place.

The Final Path to Justice for McGregor Families

What happened to your child wasn’t a “freak accident.” It was the output of a system designed by private equity firms to maximize “jumper-hours” while minimizing “attendant-pay.” The AAP warned them. ASTM gave them the spec. The parks chose margin over safety.

The park has lawyers. Their franchisor has lawyers. Palladium Equity and Seidler Equity have lawyers. You need a team that has beaten BP and litigated $10 million kidney-failure cases. You need Ralph Manginello and Lupe Peña.
