“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 Kaitlin Hill, a mother whose three-year-old son sustained a broken femur at a trampoline park. Her warning, shared hundreds of thousands of times across social media, ends with a phrase we hear in our offices every week: “We had no idea.”
If your child was recently injured at a facility in Flower Mound, or if you were hurt on a backyard trampoline while visiting a neighbor in one of our master-planned communities like Bridlewood or Wellington, you likely feel that same sense of shock. You signed a waiver at a kiosk on Long Prairie Road, or you watched your child climb onto a neighbor’s Skywalker or Jumpking trampoline, assuming the safety netting and the presence of staff meant the risk was managed.
We are The Manginello Law Firm, also known as Attorney911. Our founder, Ralph Manginello, has spent more than 25 years holding corporate defendants and insurance companies accountable for catastrophic injuries. We represent families in Flower Mound and throughout North Texas whose lives have been altered by the predictable output of a profit-driven industry. We don’t just handle personal injury cases; we dismantle the specific systems that trampoline parks use to hide evidence and deny claims.
The clock is currently running on your case. While Texas law provides a two-year statute of limitations for personal injury, the actual evidence of what happened to your child in Flower Mound is disappearing right now. Surveillance video at local parks is often overwritten in as little as 7 to 30 days. Incident reports are frequently revised by management before you even get a copy. Call us today at 1-888-ATTY-911. We speak Spanish, we advance every cost of the investigation, and we don’t charge a dime unless we win your case.
Why a Trampoline Injury in Flower Mound is Never Just an Accident
A trampoline injury is a business decision that went wrong. When your child is launched off a trampoline bed by a much larger jumper—a mechanism known as a double-bounce—it isn’t a “freak occurrence.” It is the result of a park choosing to operate below the safety levels required by the industry’s own standards.
Industry data and pediatric medical literature have established the dangers for decades. Since 1999, the American Academy of Pediatrics (AAP) has advised that trampolines have no place in a home environment. Despite this, manufacturers like Jumpking and Skywalker sell millions of units, often with inadequate warnings about the sheer velocity of energy transfer. Commercial parks took this risk and scaled it to an industrial level.
In Flower Mound, families frequent venues like the local Urban Air Adventure Park or travel to nearby facilities in Highland Village, Lewisville, and Grapevine. These facilities are often packed on Saturday afternoons with children of all sizes. When a park fails to enforce age-segregation rules or allows a 200-pound adult on the same bed as a 60-pound child, they are choosing to accept the risk of a catastrophic fracture. In a double-bounce scenario, the child’s launch force can be multiplied by up to four times. The child isn’t jumping; they are being thrown.
Ralph Manginello has spent a career litigating against some of the largest corporations in the world, including BP after the Texas City refinery explosion and massive retailers like Walmart and Amazon. We understand how national chains like Sky Zone, Urban Air, and Altitude use layered corporate structures to try and shield themselves from responsibility. Whether the injury happened on a trampoline deck on FM 2499 or a backyard in a Denton County neighborhood, we know how to find the path to maximum recovery.
The Standard of Care: ASTM F2970 and the High Cost of Neglect
Most parents in Flower Mound assume that the state or federal government inspects trampoline parks for safety. They don’t. In Texas, there is a massive regulatory gap. Under Texas Occupations Code Chapter 2151, the state regulates “Class B” inflatable rides—like the bungee trampolines or the inflatable obstacle courses you see inside many local parks—but it specifically excludes the main trampoline decks.
Because the state doesn’t set the rules, we look to the industry’s own standards to prove our cases. ASTM F2970 is the primary safety standard for commercial trampoline courts. It wasn’t written by the government; it was written by the trampoline park industry itself. When a facility in Flower Mound violates these rules, they are failing a test they helped design.
The core of most Flower Mound trampoline park lawsuits involves violations of these specific ASTM provisions:
- Attendant-to-Jumper Ratios: ASTM F2970 requires specific staffing levels. During peak times in a high-demand market like Flower Mound, parks often cut these ratios to save on labor costs. One attendant watching fifty kids is not supervision; it’s a liability.
- Age and Weight Separation: The standard requires parks to operationalize the separation of different-sized jumpers to prevent the 14x injury risk associated with mass-mismatch.
- Foam Pit Depth and Maintenance: For parks that still use foam pits instead of modern airbags, the depth must be checked daily. When foam blocks compact or have been in use for years without replacement, a child diving in head-first can strike the hard floor beneath.
- Inspection Cadence: Daily pre-opening logs are required. We often find in discovery that these logs were signed pro-forma without an employee ever actually checking the tension of the springs or the integrity of the mat.
We also compare local operations to international benchmarks like EN ISO 23659:2022. While the United States relies on voluntary standards, Europe has moved to mandatory safety requirements. We use this gap to show Texas juries that companies like Sky Zone, Inc. and Unleashed Brands (the parent of Urban Air) are operating at a safety floor that the rest of the developed world considers unacceptable.
The Waiver is Noise, Not a Wall
The most common reason parents in Flower Mound hesitate to call a lawyer is the waiver they signed at the kiosk. The park’s insurance adjuster will tell you the case is closed because of that signature. We move to prove otherwise.
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 arguments they use to try and make waivers stick. Now, he uses that same playbook to tear them apart. We approach every Flower Mound trampoline waiver with a five-vector attack strategy:
1. The Minor-Waiver Rule in Texas
Under the landmark Texas case Munoz v. II Jaz Inc., a parent generally cannot sign away a minor child’s right to sue for personal injuries. Your signature may affect your own derivative claims, but your child’s personal cause of action typically survives. If your daughter was hurt during a birthday party in Flower Mound, her rights are protected by Texas law, regardless of what you clicked on an iPad.
2. The Gross Negligence Carve-Out
No waiver in Texas can release a company from gross negligence. If the park’s management knew about a torn mat or an understaffed court and chose to stay open anyway to hit a revenue goal, that is gross negligence. A Harris County jury proved this in the Max Menchaca case against Cosmic Jump, awarding over $11 million despite a signed waiver. We look for that same subjective awareness and conscious indifference in every Flower Mound case.
3. Fair Notice and the Dresser Doctrine
Texas follows the “fair notice” doctrine established in Dresser Industries v. Page Petroleum. A waiver must be “conspicuous”—it can’t be buried in tiny font at the bottom of a twenty-page agreement. It must also meet the “express negligence” rule, specifically using the word “negligence” to describe the risk being released. Many kiosk waivers used in North Texas fail these technical legal tests.
4. Direct-Benefits Estoppel and Signer Authority
We investigate who actually signed the waiver. Was it a grandparent, an aunt, or another parent at a birthday party? Texas Family Code § 153.073 is clear: only a legal guardian or conservator has the authority to bind a child. At large gatherings in Flower Mound, non-guardians often sign for a group of kids. Under these circumstances, the waiver’s foundation as to those children is destroyed.
5. Inherent Risk vs. Operator Negligence
Waivers purport to cover “inherent risks” of jumping. An inherent risk is an awkward landing on a well-maintained court. It is NOT an inherent risk for an attendant to be on their phone while three teenagers double-bounce your child. We separate the manageable risks of the sport from the actionable negligence of the park.
Catastrophic Pediatric Injuries: Beyond the Emergency Room
A trampoline injury to a child in Flower Mound is a life-altering event. Because children’s bones and brains are still developing, the medical consequences of an impact on FM 1171 are measured in decades, not weeks.
Pediatric Growth Plate Destruction
Growth plates (physes) are the most vulnerable parts of a child’s musculoskeletal system. A Salter-Harris fracture—categories of breaks that extend through the growth plate—at age seven or eight may not show its full impact until the child hits a growth spurt at age thirteen. If the growth plate is destroyed or fused, the limb will not grow straight or to the correct length. We work with pediatric orthopedic surgeons to project these future costs, which may include corrective osteotomies or leg-lengthening surgeries years down the road.
SCIWORA and Cervical Spine Trauma
Spinal Cord Injury Without Radiographic Abnormality (SCIWORA) is a nightmare for parents. A child can land on their head or neck in a foam pit at a park near Flower Mound, have a “normal” CT scan at an emergency room, and yet still be suffering from cord ischemia. Within hours, the child may lose the ability to feel their legs. We know that a normal initial scan does not mean a child is cleared, and we hold parks accountable for failing to train staff on head and neck trauma protocols.
Traumatic Brain Injury (TBI) in the Developing Brain
A concussion at a trampoline park isn’t like a concussion an adult suffers. It interrupts the formation of neural pathways. We look for the “pediatric brain development multiplier” in every TBI case. Data published in the 2024 American Journal of Roentgenology shows that up to 1.6% of all pediatric emergency trauma visits are now trampoline-related. We ensure your family identifies the academic regression, cognitive fatigue, and mood changes that follow these injuries before you ever consider a settlement offer.
Exertional Rhabdomyolysis and the UH Case Bridge
If your child jumped for ninety minutes on a hot Texas afternoon, drank nothing but a sugary soda, and woke up two days later with dark, cola-colored urine and severe muscle pain, they may be suffering from rhabdomyolysis. This is a medical emergency that leads to acute kidney failure.
Our firm is currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis and kidney failure. We have built the top medical expert network in Texas for these cases. We know how to read the creatine kinase (CK) levels, how to document the renal tubular damage, and how to prove that the park’s failure to provide hydration and rest breaks was the direct cause of your child’s trauma.

Investigating Backyard Trampoline Accidents in Denton County
While Flower Mound is home to several high-energy commercial parks, our neighborhoods also have a high density of backyard trampolines. These residential cases are different legal animals. There are no waivers, but there are complex insurance and product liability issues.
If a neighbor’s child wandered onto your property and was hurt on your trampoline, the “attractive nuisance” doctrine in Texas holds you responsible. As a homeowner, you have a duty to secure hazardous conditions that are foreseeable to attract children. A trampoline in a backyard near Garden Ridge Blvd with a ladder left in place can easily trigger this liability.
However, the real culprit is often the manufacturer. Brands like Jumpking, Skywalker, ACON, and Springfree sell products against 25 years of medical warnings. We investigate whether the polypropylene netting was UV-degraded, whether the frame welds contained manufacturing defects, or whether the padding failed to meet ASTM F381 specifications.
If you bought a Bouncepro trampoline from Walmart or an Amazon Basics model online, we apply the “retailer-as-seller” doctrine. Under current California and Texas precedents, mega-retailers can be held strictly liable for the defects in the products they brand and sell, even if the actual manufacturing happened overseas. We have fought Walmart and Amazon before, and we don’t back down from their corporate defense firms.
The 48-Hour Evidence Preservation Protocol
The outcome of your case in Flower Mound will be decided by what we preserve this week. We have refined a 10-step case-build process that we activate the moment a family retains us.
- 24-Hour Spoliation Letter: We send a certified demand to the park, their corporate parent, and their insurer. We demand they freeze the DVR, the incident reports, the time-clock records, and the kiosk audit logs.
- Digital Forensics: If a park claims a “surveillance glitch” at the moment of injury—a pattern seen in a $3.5 million Georgia verdict—we retain forensic document examiners to interrogate the metadata of the DVR storage media.
- Waiver Versioning: We use the Wayback Machine and internal databases to capture the exact version of the waiver being used by local parks like the Urban Air on Long Prairie Rd before they have a chance to “update” the text post-injury.
- Ex-Employee Outreach: Trampoline park staff turn over at rates of 150% per year. We find the attendants who quit a week after your child was hurt. They are often our best witnesses for describing the short-staffing and broken equipment that management tried to hide.
- Scene Investigation: We deploy biomechanical engineers to the park to measure the current state of the court, the foam pit depth, and the padding integrity before remediation occurs.
- Medical Chronology: We work with specialists to build a timeline from the first moment of “the worst scream” through the long-term orthopedic prognosis.
- Corporate Structure Discovery: We don’t just sue the local LLC. We trace the money through the franchisee to the franchisor and the private equity sponsor.
- Insurance Discovery: We identify every layer, from the primary GL policy to the parent company’s excess umbrella.
- ASTM Compliance Audit: We cross-reference the internal worker manuals against the ASTM F2970 standard.
- Trial Readiness: We prepare every Flower Mound case as if a jury will decide it. That is the only way to force the insurer to make a fair offer.

Frequently Asked Questions About Flower Mound Trampoline Injuries
Can I sue if I signed the waiver at the Urban Air in Flower Mound?
Yes, in most cases. Texas law under the Munoz and Dresser decisions provides several routes to defeat a waiver, especially when a minor child is the one injured. A signed waiver is a standard defense, but it is rarely an absolute bar to recovery for gross negligence or pediatric claims.
How much is my child’s trampoline injury case worth?
The value depends on the injury and the amount of insurance we can access. Catastrophic spinal cord cases can result in awards exceeding $15 million, as seen in the Damion Collins v. Urban Air case. Serious pediatric fractures with growth plate damage typically result in settlements ranging from $500,000 to $2 million. We calculate your child’s “Life Care Plan” to ensure every future medical and educational cost is covered.
How long do I have to take action?
The legal deadline in Texas is two years, but the evidentiary deadline is much shorter. If you wait more than a month to hire an attorney, the surveillance video of your child’s accident is likely gone forever. We recommend sending a preservation demand within 72 hours of the injury.
What if the park says our kid “caused” the injury?
This is a standard insurance tactic. In Texas, children under age seven are conclusively presumed incapable of negligence. For children between ages seven and fourteen, there is a strong rebuttable presumption. The park cannot shift their duty to supervise onto a seven-year-old child.
What is the “Don’t Call 911” protocol?
Public reviews of parks in the DFW metro have alleged that staff are instructed to minimize injuries and avoid calling EMS to prevent creating a scene. This practice is evidence of a conscious indifference to patron safety and can be used to support punitive damages.
Why is the insurance adjuster being so nice to us?
The “friendly adjuster” call is a tactical trap. They are trying to get you to give a recorded statement or accept a small “medical payments” check in exchange for a full release of all claims. Never take their call without your attorney present.
How do I know if my child has rhabdomyolysis?
Look for “cola-colored” or dark urine, severe muscle swelling, and extreme lethargy 12 to 48 hours after jumping. Go to a Level 1 pediatric trauma center like Children’s Medical Center Dallas or Cook Children’s Fort Worth immediately. These facilities are the benchmark for pediatric care in our region.

Building the Life Care Plan for a Flower Mound Child
When a child is hurt, we don’t just look at the current medical bills. We build a Pediatric Life Care Plan with a Certified Life Care Planner (CLCP) and a pediatric specialist. We forecast the next seventy years of your child’s life: the orthopedic visits, the potential for corrective surgery as they age, the specialized tutoring they may need if they suffered a cognitive TBI, and the impact on their future earning capacity.
A “broken leg” at the local park on Long Prairie Rd isn’t just about a cast; it’s about the Salter-Harris fracture that will manifest as a limb-length discrepancy years from now. We ensure the settlement reflects that reality. We have recovered multi-million dollar settlements for brain and spinal injuries because we don’t stop at the surface. We go into the medicine of the growth plate and the development of the pediatric spine.
If your child is hurting today, don’t let a kiosk waiver be the reason you don’t seek justice. The insurance companies bank on you being too overwhelmed to fight. We are here to fight for you.
