Kaitlin Hill, a mother known as Kati to her friends, took her three-year-old son Colton to a trampoline park during a session marketed for the youngest jumpers. Like many families in West Lake Hills, she believed that a facility advertising “Toddler Time” had been engineered for the safety of children his size.
But a larger child—older and significantly heavier—rebounded on the same trampoline mat at the wrong instant. The energy transfer from the heavier jumper launched Colton with a force his small frame was never meant to decelerate. His femur, the strongest bone in the human body, snapped. We have read Kati’s description of that moment many times; she calls it the worst scream you could ever hear from a child. Colton spent months in a body cast. When Kati posted her warning to other parents, it was shared a quarter-million times. Her conclusion was simple and haunting: “We had no idea.”
At Attorney911, we share this story because we represent families in West Lake Hills who are currently living that same nightmare. We represent parents sitting in the waiting rooms of Dell Children’s Medical Center, watching as surgeons explain what a Salter-Harris growth plate fracture means for their child’s next decade of development. We write this because the commercial trampoline park industry and backyard manufacturers have known about these risks for more than twenty-five years, yet they continue to prioritize profit margins over the orthopedic and neurological safety of children in City of West Lake Hills.
If your family is dealing with a catastrophic injury, you need to understand that the “accident” wasn’t a fluke. It was the predictable output of a business model. We are here to help you hold them accountable.
The Reality of Trampoline Injuries in City of West Lake Hills
Trampoline parks have become a staple of the Central Texas family lifestyle. Whether it is a Saturday afternoon birthday party at the Urban Air near Bee Cave or a summer camp field trip to a nearby Altitude or Sky Zone, thousands of children from City of West Lake Hills are airborne every weekend. Nationally, trampolines send approximately 300,000 Americans to the emergency room every year. In a metro areas like City of West Lake Hills, we see a heavy concentration of these incidents because of our high park density and the intensity of our local youth sports and cheer culture.
Since 1998, our founder Ralph Manginello has been fighting for the victims of catastrophic injuries. With over 25 years of experience and admission to federal court, he has taken on Fortune 500 giants like BP, Walmart, and Amazon. We bring that same level of aggressive, high-stakes litigation to every West Lake Hills trampoline injury case. We don’t just handle “slips and falls”; we litigate the physics of a double-bounce, the compaction of a foam pit, and the failure of a park to follow its own safety curriculum.
Our firm includes associate attorney Lupe Peña, who previously worked on the other side of the table. He used to defend insurance companies and recreational facilities against these exact claims. He knows the internal playbook they use to minimize your child’s injury. He knows which waiver clauses are designed as “paper shields” and which ones have already been voided by Texas courts. For our Spanish-speaking neighbors in City of West Lake Hills, we offer direct representation. Hablamos Español. Llame al 1-888-ATTY-911. Lupe Peña habla con usted directamente—sin intérpretes.
The Standard of Care: Why Gravity is Not the Defendant
The park’s insurance adjuster will likely call you within 48 hours. They will sound concerned, but their goal is to convince you that “trampolines are just dangerous” and that by signing a waiver, you accepted the risk. We do not accept that framing, and neither do Texas courts.
Gravity is a constant, but negligence is a choice. The duty of care for commercial parks is defined by ASTM F2970, an industry standard that the trampoline industry actually wrote for itself. Every park serving West Lake Hills is expected to follow these minimum safety floors:
- Attendant-to-Jumper Ratios: Parks must have trained court monitors actively supervising every area.
- Age and Weight Separation: The industry knows that mixing a 200-pound adult with a 50-pound child is a recipe for a shattered tibia.
- Foam Pit Maintenance: ASTM F2970 dictates filling depth and replacement cadence for foam blocks.
- Daily Inspections: Parks must document that every spring, mat, and frame pad was checked before the doors opened.
When we investigate an injury in City of West Lake Hills, we don’t just look at the mat where your child fell. We subpoena the time-clock records to see if the park was understaffed. We demand the training files of the seventeen-year-old monitor who was on their phone instead of watching the court. And we look for the “systemic failure” that an arbitrator recently cited when awarding $15.6 million in a quadriplegia case against Urban Air. In that case, the franchisor, UATP Management LLC, was held responsible for 40% of the award because they failed to enforce safety changes they knew were necessary.
We are currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure—the same catastrophic muscle and organ breakdown we see in West Lake Hills children who are pushed to overexertion during two-hour “Open Jump” sessions in heated indoor facilities. We know the medicine, we know the science, and we know how to make institutional defendants pay.
Understanding the Double-Bounce Physics
The most common mechanism of injury at trampoline parks near City of West Lake Hills is the double-bounce. This isn’t just an “awkward landing.” It is a transfer of kinetic energy. When a heavier jumper lands on a trampoline bed just as a lighter jumper is pushing off, the energy transfers through the mat. This multiplies the child’s launch force by as much as four times.
The child isn’t jumping anymore; the child has become a projectile. At the apex of that launch, the body’s center of gravity is off-axis, and the child’s developing bones are not engineered to absorb the resulting landing force. This often leads to:
- Comminuted Femoral Shaft Fractures: Thigh bone breaks that require ORIF (open reduction internal fixation) with intramedullary nailing.
- Salter-Harris Type II Fractures: Injuries that go through the growth plate (physis). These are devastating because the bone may stop growing or grow crookedly, a reality that families in West Lake Hills may not fully realize for years until a leg-length discrepancy manifests.
- Traumatic Brain Injuries (TBI): Resulting from head-to-head collisions or being launched into unpadded metal frame members.
The largest reported jury verdict against a U.S. commercial trampoline park actually happened right here in Harris County. In the Cosmic Jump case, a sixteen-year-old fell through a tear in a trampoline slide onto the concrete floor beneath. Despite a signed waiver, the jury awarded $11.485 million—including $6 million in punitive damages—because the park had actual knowledge of the defect and chose to do nothing. If your child was hurt at a Sky Zone, Urban Air, or Altitude in the City of West Lake Hills area, that is the level of accountabilityเรา we pursue.
“But I Signed a Waiver”—Why the Waiver is Not a Wall
You likely signed a digital waiver on an iPad in a crowded lobby while a line of kids waited behind you. The park wants you to believe that signature was the end of your legal rights. In Texas, that is simply not true.
We attack waivers in City of West Lake Hills on several proven fronts:
- The Munoz Rule: Under Munoz v. II Jaz Inc., Texas courts have held that a parent’s pre-injury signature generally cannot waive a minor child’s own tort claim against a commercial operator. Your child’s right to a recovery doesn’t belong to you; it belongs to them, and you cannot sign it away.
- Gross Negligence: A waiver for “ordinary” negligence cannot shield a park from “gross” negligence. If the park knew a mat was torn, or if they knowingly understaffed a court during a peak holiday weekend, the Cosmic Jump precedent shows that the waiver stops applying.
- The Dresser Fair Notice Doctrine: Texas law requires specific formatting for waivers to be enforceable. The release must be conspicuous and explicitly use the word “negligence.” Many kiosk waivers used by national chains fail this test on a technical level.
- Bilingual Inequity: Under the Delfingen doctrine, if your family speaks Spanish as a primary language and the park only provided an English waiver without a translation, the contract may be voided for lack of valid formation.
Our team, lead by Ralph Manginello, knows these attack vectors because we live in the same Texas case law every day. We know that the parent-company giants behind these parks—entities like Sky Zone, Inc. (backed by Palladium Equity Partners) or Unleashed Brands (parent of Urban Air, recently acquired by Seidler Equity Partners) —hire elite defense firms to protect their Sales. We simply fight harder.
Evidence Preservation: The 7 to 30 Day Window
If your child was recently injured in a West Lake Hills trampoline incident, the clock is not just running on the statute of limitations—it is running on the evidence.
Most trampoline park surveillance systems in Central Texas are set to overwrite their DVR data in as little as 7 to 30 days. If you wait to call an attorney, the video of the attendant on their phone during your child’s accident will be gone forever. Furthermore, waiver kiosk databases frequently purge version history and metadata on short cycles.
The Manginello Law Firm sends a formal spoliation letter within 24 hours of your retention. This letter makes it a legal violation for the park to delete video, “revise” incident reports, or replace broken equipment before our biomechanical engineers can inspect it. We treat every West Lake Hills case with the same forensic discipline we brought to complex litigation against multinational oil companies.
Catastrophic Injuries and the Pediatric Life-Care Plan
When a child in City of West Lake Hills suffers a spinal cord injury or a complex growth plate fracture, the medical bills you see today are only a fraction of the total cost. A pediatric injury involves a developing brain and body. A “trampoline fracture” at age seven can lead to a decade of orthopedic monitoring, corrective osteotomies at age twelve, and permanent gait changes as an adult.
We collaborate with elite experts to document these damages:
- Biomechanical Engineers: To model the energy transfer and prove the park’s equipment failed the ASTM F2970 standard.
- Pediatric Orthopedic Surgeons: To explain to a jury why a Salter-Harris fracture isn’t just a “broken bone.”
- Life-Care Planners: To calculate the next 60 years of medical needs, physical therapy, and home modifications.
- Forensic Economists: To demonstrate the loss of future earning capacity even for a “mild” traumatic brain injury.
We currently litigate a major lawsuit involving rhabdomyolysis and acute kidney failure, giving us unique insight into the “crush-intensity” injuries often seen in foam pits. We have seen how teenagers can sustain a vertebral artery dissection or a “spinal-cord stroke” from a single botched flip—an injury frequently and dangerously misdiagnosed as a panic attack by under-trained staff.
Backyard Trampoline Dangers in City of West Lake Hills
While commercial parks are high-risk, the backyard trampolines in City of West Lake Hills neighborhoods—manufactured by Jumpking, Skywalker, ACON, or Springfree—carry their own hazards. The American Academy of Pediatrics (AAP) has advised against any recreational trampoline use at home since 1999.
We hold manufacturers accountable for:
- Net Enclosure Failures: UV-degraded polypropylene netting that tears when a child impacts it.
- Manufacturer Defects: Frame welds that fail or rusted springs that should have been covered by more durable padding.
- Failure to Warn: Manuals that hide the “no one under 6” rule (ASTM F381) in fine print.
If a neighbor’s trampoline in City of West Lake Hills injured your child, the “attractive nuisance” doctrine may apply. This Texas legal principle holds homeowners liable when they maintain a hazardous condition that is foreseeable to attract and injure children. In these cases, we look at every insurance layer—from homeowners’ primary liability to umbrella policies that often exist in affluent West Lake Hills households.
Frequently Asked Questions for West Lake Hills Parents
My child broke her leg at a birthday party, but the host parent signed the waiver. Am I bound by it?
Almost certainly not. In Texas, a person cannot sign away the legal rights of someone else’s child unless they are the legal guardian. Furthermore, per Munoz v. II Jaz, even your own signature is likely not enough to bar your child’s personal claim for damages.
What is the “Don’t Call 911” policy?
There have been multiple reports, including a prominent parent review from an Urban Air location, alleging that park management instructs employees to minimize injuries and avoid calling 911 to prevent bad publicity and official incident records. If the park delayed emergency care for your child in City of West Lake Hills, that is evidence of gross negligence.
How much does a trampoline injury lawyer cost?
We work on a contingency fee basis. This means you pay nothing up-front and zero unless we win. We advance all costs for the biomechanists and pediatric specialists your case requires. As Chad Harris, one of our clients, noted: “You are NOT just some client… You are FAMILY to them.” We invest our own resources because we believe in holding these multi-million dollar chains accountable.
How common is rhabdomyolysis at trampoline parks?
It is more common than many families in West Lake Hills are told. Exertional rhabdo happens when a child jumps for 90-120 minutes straight in a hot facility without adequate hydration. If your child has “cola-colored” urine, severe muscle pain, or confusion 12-48 hours after jumping, seek an ER immediately. Our experience with the UH rhabdo case means we know exactly what labs to look for to prove the park’s protocols failed.
The park replaced the equipment right after my child was hurt. Is that allowed?
Under Texas law, this is often considered a “subsequent remedial measure.” While the park may claim they were just making things safer, we use this as evidence of exactly what was feasible before your child got hurt. This is also why sending our spoliation letter within 24 hours of the accident is so critical.
Why West Lake Hills Families Choose The Manginello Law Firm
Most personal injury firms treat trampoline cases as generic “accidents.” We treat them as part of a specialized practice area backed by decades of battle-tested litigation. We have gone toe-to-toe with multinational corporations in the BP Texas City refinery litigation—we are not intimidated by the private equity teams that own national trampoline chains.
We have recovered multi-million dollar settlements for traumatic brain injuries and spinal cord injuries. We bring federal court expertise to every negotiation. And we understand that for a family in City of West Lake Hills, this isn’t just about a “check”—it is about ensuring your child has the resources for a full recovery, no matter how long it takes.
If someone else’s negligence changed your child’s life, you deserve an attorney who treats your family like his own. That is the Attorney911 promise.

The Liable Party Hierarchy: Who Really Pays?
When we file a lawsuit for a West Lake Hills family, we identify every layer of financial responsibility. One of the most common mistakes other firms make is only suing the local “LLC” on the building lease. Those entities are often undercapitalized. We follow the money upstream:
- The Operator LLC: The immediate business on the property.
- The Franchisee: The ownership group that may run multiple locations in Central Texas.
- The Franchisor: Entities like Sky Zone Franchising LLC or Urban Air Franchise Holdings. They mandate the safety manuals and conduct the audits. If they failed to pull a franchisee’s permit after a history of violations, they are on the hook.
- The Parent Conglomerate: This is where the major insurance towers live. For Sky Zone, DEFY, and Rockin’ Jump, that is Sky Zone, Inc. (formerly CircusTrix). For Urban Air, it is Unleashed Brands.
- The Component Manufacturer: If a mat seam blew out or a harness failed (similar to the Lakhani case), the manufacturer of that high-performance equipment bears strict product liability.
We have the experience to manage this “5-layer stack.” We’ve litigated against the same caliber of corporate defense firms that the PE partners at Palladium Equity or Seidler Equity utilize. We know how to pierce the corporate shields that try to separate the billion-dollar parents from the dangerous local parks.
Medical Specificity in Trampoline Trauma
Generic legal content speaks about “broken bones.” We speak about the medicine. Effective litigation in West Lake Hills requires understanding precisely what the doctors are seeing in the trauma bay:
- SCIWORA (Spinal Cord Injury Without Radiographic Abnormality): This is a critical pediatric diagnosis. A West Lake Hills child may have a “normal” CT scan at the ER but still suffer from a spinal cord injury because their ligamentous structures are so flexible. If a park monitor told your child to “walk it off” after a head-first foam pit entry, they likely extended the window of ischemia, causing permanent damage.
- Vertebral Artery Dissection: Extreme neck torque during a double-bounce can tear the lining of the artery, causing a delayed-onset stroke. This was the mechanism in the viral Elle Yona case, which has 27 million views.
- Acute Compartment Syndrome: If a tibial fracture produces intense swelling, it can cut off blood flow to the limb. If not treated with an emergent fasciotomy within six hours, the muscle and nerve tissue die. This is why immediate, high-level trauma care at a facility like Dell Children’s is non-negotiable.
Our active $10 million UH hazing case involves these exact physiological markers. We have the expert medical network already in place to testify on the CK levels, the myoglobin cascade, and the standard of care for compartment syndrome.
The International Safety Gap
Parents in West Lake Hills deserve to know that the rest of the world treats these parks with far more scrutiny than the United States. While our parks follow “voluntary” ASTM standards, Europe adopted EN ISO 23659:2022, a mandatory standard that covers design, airlocks, and foam pit safety in deep detail. Australia mandates AS 4989:2015.
The U.S. trampoline park industry operates at a safety floor that the international community treats as a failure. When chains like Sky Zone or Urban Air tell you they meet “the industry standard,” we ask them why they aren’t meeting the binding international ones. That gap is evidence of a conscious decision to prioritize lower operating costs over the highest level of patron safety.

Frequently Asked Questions About Trampoline Injuries in City of West Lake Hills
How long do I have to sue a trampoline park in Texas?
In Texas, the statute of limitations is 2 years for personal injury. However, for a minor under the age of 18, the clock is “tolled” (paused) until their eighteenth birthday. This means a minor effectively has until age 20. However, the evidence (video, maintenance logs) is often destroyed in the first 30 days. You must act early so we can preserve your case.
Is it true that employees are told not to call 911?
Public reviews of parks in Southlake and other Texas cities have alleged that managers instruct staff to minimize the appearance of injury and handle things “in-house” rather than calling 911. This is a catastrophic training failure that we investigate in every case.
Can I sue for “gross negligence” if I signed the waiver?
Yes. In City of West Lake Hills and throughout Texas, a waiver for ordinary negligence does not bar a claim for gross negligence. If the park had a subjective awareness of an extreme risk (like a hole in a mat or dangerously low padding) and ignored it, the waiver does not apply.
What is a Salter-Harris fracture?
This is a fracture that involves the growth plate of a child’s bone. Because children in West Lake Hills are still growing, a break through the physis can cause the bone to stop developing at that end, leading to permanent limb-length discrepancy. These cases require a life-care plan to account for future surgeries.
My child developed dark urine two days after jumping. Is that a legal case?
Yes. Dark urine (the color of tea or cola) is a sign of rhabdomyolysis or kidney failure from extreme muscle breakdown. If the park allowed your child to jump for extended hours without water in a hot facility, they may be liable for the resulting medical emergency.
What if my child was hurt at a neighbor’s house in West Lake Hills?
These cases usually fall under homeowners’ insurance and the “attractive nuisance” doctrine. We look for every layer of insurance to ensure the child’s medical costs are covered without destroying a neighborly relationship.
Do you handle cases outside of City of West Lake Hills?
Yes. Our offices are in Houston, Austin, and Beaumont, but we handle trampoline injury cases across Texas and nationwide. We travel where the evidence is, and we association with local counsel where required by court rules—at no additional cost to you.
Why should I choose your firm over a local West Lake Hills generalist?
Most generalist firms don’t know the ASTM F2970 standard or the corporate structure of Palladium Equity and Seidler Equity. We have built our firm around catastrophic injury work, and our team includes an attorney who spent years defending these exact businesses. We use their playbook against them to get you the maximum recovery.
What should I do with my child’s grip socks and wristband?
Keep them. They are physical evidence of the day and time of the visit. Do not wash the socks—they may contain trace evidence of the surface condition where the injury occurred.
Will I have to go to court?
Most cases settle pre-trial, but we prepare every City of West Lake Hills case as if it is going to a jury. That preparation is why insurance companies pay. If they refuse to be reasonable, Ralph Manginello is a trial veteran who has beaten Fortune 500 defense teams for over two decades.
