One bounce. One bad landing. One broken neck. That is all it takes for a Saturday afternoon at a trampoline park to become a lifetime of medical equipment and trauma bays. For families in Lowry Crossing, these facilities represent a common destination for birthday parties and weekend fun, but beneath the neon lights and loud music lies a systemic architecture of risk. At the Sky Zone or Urban Air locations near Lowry Crossing, parents are handed an iPad and told to “sign in” at a kiosk. What they are actually doing is signing a document drafted by corporate counsel designed to strip away the legal rights of their children before they ever touch a trampoline mat.

We have spent more than twenty-five years representing victims of catastrophic injuries. Ralph Manginello founded our firm in 1991 with a commitment to holding multinational corporations accountable, from the BP Texas City refinery litigation to current $10 million lawsuits against major institutions like the University of Houston. When your child is injured in Lowry Crossing, you aren’t just fighting a local park operator; you are up against private equity-backed conglomerates like Palladium Equity Partners or Seidler Equity Partners. They have armies of lawyers. We have Ralph Manginello. We have Lupe Peña—an attorney who used to sit on the other side of the table, defending insurance companies and recreational facilities. He knows their playbook because he helped write it. Now, he uses that insider knowledge to dismantle their defenses for our clients.

What happened to your child at a park near Lowry Crossing wasn’t a “freak accident.” It was the predictable output of a business decision. The American Academy of Pediatrics (AAP) has been warning parents since 1999 that trampolines do not belong in recreational centers or homes. The industry knows this. They even wrote their own safety standard—ASTM F2970—to create a “safety floor.” Yet, on busy weekends in Collin County, that floor is routinely ignored to hit margin targets. When a park staffs at 50% of the required attendant-to-jumper ratio, or fails to separate a 200-pound adult from a 50-pound child, they are gambling with your family’s future. We are here to make sure they stop winning that gamble.

The Physics of Failure: Why Lowry Crossing Families Are at Risk

Trampolines are engineered to store and release elastic potential energy. In a controlled environment with one jumper, this is predictable. In a commercial park near Lowry Crossing, it is chaotic. The most common catastrophic mechanism is the “double-bounce.” If a larger jumper lands on the same mat while a smaller child is pushing off, the energy transfer can multiply the child’s launch force by up to four times. The child isn’t jumping anymore—they have been converted into a projectile.

This energy math is exactly why ASTM F2970 requires parks to operationalize age and weight separation. When you see a teenager at an Urban Air or Altitude near Lowry Crossing scrolling on their phone while a teenager and a toddler jump on adjacent beds, you are witnessing a direct violation of the industry’s own safety standard. Most personal injury firms handle a trampoline case like a standard slip-and-fall. We don’t. We retain biomechanical engineers to model the exact Newtons of force applied to your child’s tibia or cervical spine. We can cite ASTM F2970 Section 10 from memory. When we depose a park’s operations manager, we know their safety manual better than they do.

The Hidden Danger of the Foam Pit and Airbag

Many parents in Lowry Crossing believe the foam pit is the “safe” zone. The data says otherwise. The current peer-reviewed benchmark, Teague et al. in Pediatrics (January 2024), tracked 13,256 injuries and found that foam pits have an injury rate of 1.91 per 1,000 jumpers—nearly double the rate of open courts. The mechanism is brutal: a child lands head-first, their head wedges between foam cubes, and their body’s momentum continues. This produces a cervical hyperflexion injury—the same biomechanics as a diving accident in a shallow pool.

The industry knows foam pits are dangerous. That is why chains like Sky Zone and DEFY have been largely replacing them with pressurized airbags. This migration is a silent admission that the previous design was defective. If the facility near Lowry Crossing where your child was hurt still uses a foam pit, they have made a cost decision to keep an outdated, high-risk attraction in service. We hold them accountable for that choice.

Who Is Watching Your Child? The Staffing Gap Near Lowry Crossing

The person standing at the edge of the court in Frisco or McKinney responsible for your child’s life is, on average, a 17-year-old making near minimum wage. They typically receive two to four hours of training before they are put in charge of a hundred live jumpers. Most have no CPR certification, no first-aid training, and no AED experience.

In Washington, the Department of Labor fined Sky Zone nearly $90,000 for working their teenage employees longer hours than allowed by law. This is a window into the corporate culture of these chains. If they will break labor laws for their own teenage staff, why should anyone believe they follow safety standards for yours? Our firm pursues a “negligent training and supervision” theory in every case. We don’t just look at the minutes before the injury; we subpoena the individual monitor’s personnel file, their initial orientation checklist, and their time-clock records to prove they were overworked or undertrained.

The “Paper Shield”: Why Your Signed Waiver Does Not End Your Case

Every adjuster who calls a Lowry Crossing family starts with the same sentence: “I see here that you signed a waiver.” They want you to believe that signature is a brick wall. In Texas, it is a wet paper bag. Our waiver-defeat strategy, led by Lupe Peña, uses four primary attack vectors:

  1. The Gross Negligence Carve-Out: In the landmark Houston case Max v. Cosmic Jump, a jury awarded $11.485 million because they found the park was grossly negligent. In Texas, no waiver can release a defendant from gross negligence—meaning a conscious disregard for a known risk. Operating a park below ASTM F2970 staffing levels is gross negligence.
  2. The Fair Notice Doctrine: Under Dresser Industries v. Page Petroleum, a Texas waiver must be “conspicuous.” If the release was buried in a twenty-page iPad click-through or used small font with no bold headings, it fails the fair notice test. If the word “negligence” does not appear clearly, the waiver is void.
  3. Parental Indemnity for Minors: In Texas, the ruling in Munoz v. II Jaz Inc. established that a parent cannot sign away a child’s independent right to sue for personal injuries. You may have signed for yourself, but you did not—and could not—legally destroy your child’s claim.
  4. Bilingual Formation Issues: If your family’s primary language is Spanish and you were presented with an English-only iPad waiver at a busy counter in McKinney or Plano, the Delfingen doctrine allows us to challenge whether a valid contract was ever formed.

Catastrophic Injuries: The Medical Reality for Lowry Crossing Victims

A “broken leg” at a trampoline park is rarely just a broken leg. Because pediatric bone is more pliable than adult bone, children often sustain “Salter-Harris” fractures—injuries that go through the growth plate. A Salter-Harris Type II fracture at age eight can produce a limb-length discrepancy that doesn’t manifest until the child is fourteen. If your attorney doesn’t understand pediatric orthopedics, they will settle your case for today’s ER bill and leave ten years of future surgeries on the table.

We also recognize the subtle, deadly presentation of SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. A child lands head-first in a foam pit, their initial CT scan at Medical City Plano or Children’s Medical Center Plano looks normal, and they are sent home. Six hours later, they are paralyzed. The ligaments are too flexible to show a “break” on a standard CT, but the spinal cord has sustained ischemic damage. We know which MRI sequences are required to catch this before it’s too late.

The Rhabdomyolysis Bridge

Perhaps the most under-diagnosed injury in trampoline parks is exertional rhabdomyolysis. A child jumps for ninety minutes in a hot, poorly ventilated facility near Lowry Crossing, drinks a sugary soda instead of water, and goes home exhausted. Two days later, their urine is the color of cola, and their kidneys are failing. This “rhabdo” is caused by muscle cells rupturing and spilling myoglobin into the bloodstream. Our firm is currently litigating a $10 million case involving rhabdomyolysis; we have the medical experts and the institutional-accountability playbook to prove the park’s failure to provide hydration and rest intervals is what caused your child’s kidney failure.

48-Hour Evidence Preservation: The Clock Is Running in Collin County

In Lowry Crossing, the most important part of your case isn’t the law; it’s the video. Trampoline park DVR systems are typically set to overwrite every 7 to 30 days. If you wait until your child is out of the cast to call a lawyer, the footage of the attendant on their phone is gone forever.

The moment we are retained, we send a formal spoliation letter. We demand the park preserve:

  • Multi-angle surveillance footage.
  • The original incident report (before it is “revised” by corporate risk management).
  • The waiver kiosk metadata showing how long you actually had to read the terms.
  • The shift logs for EVERY court monitor on duty.
  • RFID wristband data showing how many jumpers were on the court.

If a park tells us the video “glitched,” we don’t take their word for it. We retain digital forensic examiners to interrogate their servers. In a Georgia case (Mathew Knight), a jury awarded $3.5 million because the park’s cameras “happened” to glitch during the injury. We leverage that same intensity for every Lowry Crossing client.

Frequently Asked Questions for Lowry Crossing Parents

Can I sue if I signed the paper at the front desk?

Yes. As discussed, the “paper” (waiver) in Texas is governed by the Dresser and Munoz doctrines. It does not cover gross negligence, and in Texas, it generally does not bar a child’s own personal claim. The adjusters use the waiver as a psychological tool to keep you from calling us. Don’t let it work.

How much is a trampoline injury settlement worth in Texas?

Every case is unique, but the ranges are established. A serious pediatric fracture with growth-plate damage often anchors in the $500,000 to $2,000,000 range. Catastrophic spinal cord injuries can reach $10,000,000 to $40,000,000 to cover 70 years of life-care planning. We use forensic economists to ensure we aren’t just looking at today’s bills, but at your child’s lifelong earning capacity.

The park manager said it was my child’s fault. Does that matter?

No. Texas follows a “modified comparative fault” rule (§33.001). As long as the defendant is at least 50% responsible, you can recover. More importantly, children under seven are generally presumed incapable of negligence in Texas, and children under fourteen are rebuttably presumed incapable. The park cannot outsource its safety duty to a seven-year-old.

What if the park is a franchise?

This is our favorite defense to break. The franchisor (like Sky Zone Franchising LLC) often claims they are just a “brand licensor.” We prove that by mandating training manuals, inspection cadences, and uniform safety rules, they have “retained control.” Under the Sampson doctrine in Texas, we reach the deep pockets upstream.

What should I avoid saying to the insurance company?

Everything. Do not take the “friendly adjuster” call. Their job is to get you to say your child was “jumping fast” or “having fun” to use it as evidence of assumption of risk. Your only sentence should be: “Talk to my lawyers at Attorney911.”

Verbatim Parent-Query FAQ Library

“Can I sue if I signed the waiver?”
In Texas, a waiver is never a total shield. If the park violated ASTM F2970 standards, that is evidence of gross negligence. Under the Moriel decision, waivers cannot release gross negligence. Furthermore, the Munoz ruling clarifies that you cannot sign away your minor child’s right to seek justice.

“My kid broke a bone at the park. What do I do?”
First, ensure they have seen a specialist, not just an ER doctor. A pediatric orthopedist must check the growth plates. Second, stop all communication with the park. Third, call us at 1-888-ATTY-911 within 24 hours so we can freeze the surveillance video.

“They wouldn’t call 911—is that legal?”
It is a documented industry tactic to downplay injuries. At a park in Southlake, parents reported staff were instructed not to call 911. We treat this as evidence of a “conscious indifference” to safety, which is a key part of proving gross negligence and securing punitive damages.

“How much does a trampoline-park lawyer cost?”
With us, the upfront cost is zero. We work on a contingency basis. We pay for the biomechanical engineers, the experts at South Texas College of Law, and the medical consultants. We only get paid if we secure a check for your family.

“Is a kiosk waiver even enforceable?”
Often, no. If you were rushed, if the print was small, or if it didn’t specifically use the word “negligence” as required by the Dresser doctrine, it is legally insufficient. Texas courts have high standards for “Fair Notice,” and iPad kiosks rarely meet them.

State-Specific Parent-Facing Prompts (Texas)

If you are in Texas, you have specific advantages. Our state supreme court has consistently protected children’s claims in the Munoz lineage. Even with the new Cerna ruling on delegation clauses, we have strategies to keep your case in a local courtroom rather than secret arbitration. Texas juries have shown an willingness to hit parks with multi-million dollar verdicts when they hide torn equipment or understaff courts.
