At a birthday party near Sandy Oaks, the music is loud, the air is thick with the scent of concession-stand pizza, and your child is doing exactly what you paid for them to do: having the time of their life. You stood at the kiosk twenty minutes ago, scrolled through several screens of legal text you didn’t have time to read with a line of parents behind you, and tapped “I agree.” You handed your child a colored wristband, watched them race onto the court, and for a moment, everything felt like safe, high-energy fun.
Then the double-bounce happened.
In less than two seconds, the kinetic energy of a much larger jumper transferred through the trampoline bed and launched your child with four times the force they could have generated on their own. They didn’t just jump; they were catapulted. The landing didn’t happen on the center of the mat. It happened on the edge, where a spring cover had slipped just enough to expose the steel coils beneath.
You heard it before you saw it. As Kati Hill, the mother of a three-year-old who suffered a broken femur at a similar park, told ABC News: “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.”
In Sandy Oaks, when that scream happens, your life changes. You find yourself in the back of an ambulance on the long, quiet drive toward University Hospital in San Antonio or Methodist Children’s Hospital, watching a paramedic stabilize a limb that may never grow the same way again. You find yourself at a bedside, watching a surgeon explain what happens when a growth plate is destroyed at age nine. And eventually, you find yourself looking at that “Participation Agreement” you signed and wondering if you signed away your child’s future.
We are Attorney911, and we are here to tell you that you didn’t. That piece of paper is not the shield the park wants you to believe it is.
What happened to your child in Sandy Oaks wasn’t a “freak accident.” It was the predictable output of a system designed to maximize margin by cutting corners on safety. Since 1998, Ralph Manginello has been fighting corporate defendants who put profits over people. Our firm includes attorneys like Lupe Peña, who previously worked on the defense side, representing the very insurance carriers and recreational businesses we now sue. He knows exactly which waiver clauses are airtight and which ones are full of holes. He knows their playbook because he helped write it.
We represent families in Sandy Oaks. We represent children. We represent the parent who is being told by a park manager to “just walk it off” while the security DVR is already counting down the days until the footage of the injury is overwritten.
Whether your child was injured at an Urban Air, an Altitude, or The Rush Fun Park in the San Antonio metro, or on a defective backyard Jumpking or Skywalker trampoline in your own Sandy Oaks neighborhood, you need more than a lawyer. You need a litigation team that can quote ASTM F2970 from memory and knows how to reach the private equity money upstream.

The Sandy Oaks Parent’s Guide to Trampoline Negligence
In a community like Sandy Oaks, where family life transitions between the quiet of the Bexar County countryside and the high-energy entertainment centers of the San Antonio metro, trampoline injuries represent one of the most significant pediatric trauma risks we see. Nationally, more than 300,000 trampoline-related emergency room visits happen every year. The vast majority of these victims are children.
For parents in Sandy Oaks, the danger follows you from the backyard to the commercial park. The American Academy of Pediatrics (AAP) has been warning about this since 1999. In their 2012 reaffirmation and 2019 update, the AAP stated clearly: trampolines should not be used at home, and they should not be used for routine recreation even at supervised facilities.
Most manufacturers and park operators don’t tell you that. They sell the product, they market the party packages, and they count on the fact that most Sandy Oaks families have “no idea” about the risks until the bone breaks.
The Physics of the Sandy Oaks Double-Bounce
To understand why the injury happened, you have to understand the physics that the park’s minimum-wage monitors frequently ignore. ASTM F2970 is the safety standard written by the trampoline park industry itself. It requires parks to operationalize the separation of age and weight groups.
Why? Because of double-bounce energy transfer. When a 200-pound adult lands on a trampoline mat at the same moment a 60-pound child from Sandy Oaks is pushing off, the stored energy in the bed doesn’t dissipate—it transfers. It multiplies the child’s launch force by up to 4x. The child is no longer in control of their flight path or their landing. This is the mechanism that shatters tibias and compresses spines.
When you walk into a park near Sandy Oaks on a Saturday afternoon and see teenagers and toddlers sharing the same court, you are looking at a violation of the industry’s own safety floor. That isn’t an “inherent risk.” It is negligence.
Commercial Trampoline Parks Serving Sandy Oaks
Sandy Oaks families typically frequent the major entertainment hubs in the South San Antonio area. You likely recognize the names:
- Urban Air Trampoline & Adventure Park: With locations across the San Antonio metro, including South San Antonio and NE San Antonio, Urban Air is a franchise-heavy giant. Its parent company, Unleashed Brands, was acquired by Seidler Equity Partners in 2023 amid a wave of lawsuits. Their “Sky Rider” zipline has been implicated in a chain-wide pattern of strangulations and falls.
- Altitude Trampoline Park: Headquartered in Fort Worth with a major location on IH-10 West in San Antonio, Altitude markets itself as the “fastest-growing” chain. They are also known for their 30-foot climbing walls—the same design signature involved in the Matthew Lu wrongful death case in Gastonia, North Carolina, where a harness failure led to a lethal fall onto concrete.
- The Rush Fun Park: Based in San Antonio with multiple area locations, this regional operator competes with the national chains, often using similar staffing and maintenance models that can slip during peak holiday or summer break traffic.
- Ground Control Trampoline Park: Located on Marbach Rd, they specialize in flush in-ground trampolines, which change the depth-perception and landing mechanics for Sandy Oaks jumpers.
Every one of these chains operates through a complex, 5-layer defendant stack designed to hide the deep pockets. The operator LLC at the park where you paid your admission is often undercapitalized by design. But above them is the franchisee, the franchisor (like Sky Zone Franchising LLC or UATP Management LLC), the corporate parent (Sky Zone, Inc. or Unleashed Brands), and finally the private equity sponsor.
We don’t just sue the local park. We find the money upstream. In the Damion Collins case against an Urban Air in Kansas, an arbitrator awarded $15.6 million for a paralysis injury, holding the franchisor responsible for 40% of the award due to a “systemic failure” to implement safety changes. That is the same level of accountability we bring to every Sandy Oaks case.
The Waiver Is Not a Wall: Texas Law and Your Rights
The biggest hurdle parents in Sandy Oaks believe they face is the waiver they signed on the iPad. The park manager might even point to it while your child is being loaded into the ambulance.
“You signed the release,” they’ll say. “You assumed the risk.”
Here is what they won’t tell you: Texas law has very specific rules about what a waiver can and cannot do, and our firm knows how to dismantle them.
1. The Munoz Rule (Minor Claims)
In the landmark Texas case Munoz v. II Jaz, Inc. (1993), the court held that a parent in Texas cannot pre-emptively waive a minor child’s personal injury cause of action. While your signature might affect your own rights, it does not extinguish your child’s right to be compensated for their injuries.
2. The Gross Negligence Carve-Out
Under Texas law, including the standards set in Moriel and applied in the Cosmic Jump $11.485 million verdict in Harris County, a waiver cannot release a defendant from gross negligence. If the park knew that a mat was torn, that a monitor was missing from a foam pit, or that their equipment was failing ASTM F2970 standards, and they let your child jump anyway, the waiver fails.
3. The Dresser Fair Notice Doctrine
Dresser Industries v. Page Petroleum requires that any release of negligence in Texas be “conspicuous” and meet the “express negligence” doctrine. If the word “negligence” isn’t clear, bold, and easily readable, the waiver may be legally void for everyone, including adults.
4. The Delfingen Spanish-Language Defense
Sandy Oaks is a vibrant, bilingual community. Under the Delfingen US-Texas v. Valenzuela doctrine, if a park presented you with an English-only waiver and you primary language is Spanish, the contract may be invalid due to a failure of formation. Lupe Peña speaks with our Spanish-primary families directly to ensure no adjuster uses a language gap to cheat your family out of justice.
Catastrophic Injuries: The Medical Stakes for Sandy Oaks Families
When we represent a child from Sandy Oaks, we aren’t just looking at the ER bill from last night. We are looking at the next seventy years of their life.
Salter-Harris Growth Plate Fractures
In developing children, the growth plate (physis) is the softest part of the bone. A trampoline landing that would only sprain an adult’s ankle can shatter a child’s growth plate. These are called Salter-Harris fractures. A Type III or Type IV injury can cause the bone to stop growing or to grow crooked. This may not manifest fully until your child hits a growth spurt years after the accident.
Most firms settle these cases too early. We don’t. We work with pediatric orthopedic surgeons and life-care planners to project the cost of corrective surgeries and long-term monitoring through skeletal maturity.
SCIWORA and Cervical Injuries
Children in Sandy Oaks are uniquely vulnerable to SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. A head-first landing into a compacted foam pit can stretch the spinal cord even if the CT scan shows no broken bones. If the park monitors aren’t trained to recognize the signs, and your child is allowed to walk off the court, the ischemia (loss of blood flow) to the cord can worsen, resulting in permanent paralysis.
Rhabdomyolysis: The Under-Recognized Crisis
If your child jumped for ninety minutes in a heated San Antonio park during a July “glow night” and arrives home with dark-colored urine and rock-hard muscle pain, they may be suffering from exertional rhabdomyolysis. This is the breakdown of muscle tissue that can lead to acute kidney failure. our firm is currently litigating a $10 million lawsuit against the University of Houston involving this exact pathology. We know the nephrology experts, and we know how to prove that the park’s failure to provide hydration and rest intervals is what caused your child’s kidneys to crash.
Why the First 48 Hours in Sandy Oaks Matter for Your Case
The moment an injury happens in a park near Sandy Oaks, the operator’s risk management team is already at work. They aren’t working to help you; they are working to protect the chain.
The Evidence Clock is Ticking:
- 7 to 30 Days: This is the typical cycle before park surveillance DVRs rotate and overwrite the footage of your child’s accident.
- 72 Hours: Some kiosk waiver databases purge version history on a rolling 3-day schedule.
- Overnight: Broken springs are replaced, foam pits are refilled, and incident reports are “revised” in the computer system to change “monitor was on phone” to “patron was running.”
We do not wait for the park to “do the right thing.” We send a formal spoliation demand by certified mail within 24 hours of your call. We demand the internal worker manuals, like the Sky Zone “BE AWARE OF THE PADS” document produced in Massachusetts, which showed the company warned workers about hazards they never disclosed to parents.
The Liability Stack: Who Pays for a Sandy Oaks Injury?
We look for every available insurance layer to ensure your child’s recovery fund is full.
In a Commercial Park Case:
- Operator’s Primary GL: The $1M – $5M floor.
- Franchisee Umbrella: Often adds $5M – $25M.
- Franchisor Additional-Insured Coverage: We target the national towers of Sky Zone or Urban Air.
- Component Manufacturers: The vendors who sold the park defective foam or mats.
- TDI Class B Coverage: In Texas, if the injury happened on an inflatable attraction (bungee tramp, Sky Rider), the park must have a $1 million policy on file with the State. We pull those records immediately.
In a Backyard Case:
If your child was hurt at a neighbor’s house in Sandy Oaks, the attractive nuisance doctrine applies. Even if the child was uninvited, a homeowner who leaves a trampoline accessible and unsecured can be liable. We look at the homeowner’s GL and umbrella policies, but more importantly, we target the manufacturers like Jumpking or JumpSport. If the net failed because of UV-degradation or a weak anchor, that is a product liability claim worth millions that doesn’t rely on your neighbor’s insurance.
Sandy Oaks Trampoline Injury FAQ
How long do I have to sue a trampoline park in Texas?
For adults, the limit is two years from the date of the injury. For minors in Sandy Oaks, the two-year clock is tolled (paused) until they turn 18, meaning they have until their 20th birthday. However, you should never wait. The evidence (video, witnesses) will be gone in weeks. We file early to preserve your child’s case.
Can I sue if the park’s sign said “Jump at your own risk”?
Yes. A sign is not a contract, and even a contract cannot excuse gross negligence. In Texas, “assumption of risk” is not a separate defense that can end your case; it’s just a factor the jury considers when looking at the percentage of fault under Chapter 33 of the Civil Practice and Remedies Code.
What if my child hit their head and seems better today?
Traumatic Brain Injury (TBI) in children often has a “latent” phase. Symptoms like irritability, academic regression, and cognitive fatigue can emerge weeks or months after the impact. This is why we work with pediatric neurologists to establish a baseline before you sign any settlement papers.
Is it really expensive to hire a trampoline injury lawyer?
Not at our firm. We work on a contingency fee basis, which means we get $0 unless we win your case. We advance all the costs—the $20,000 for a biomechanical engineer to reconstruct the jump, the $15,000 for a life-care planner, the filing fees, and the expert witnesses. Your child’s recovery fund stays intact while we fight.
The park manager said it was my child’s fault for trying a flip. Is the case over?
No. Most parks classify flips as “Advanced Skills” under ASTM F2970. If the park allowed your child to attempt these moves on a public court without proper training or segregated zones, the park—not the child—violated the safety standard.
What if the park didn’t call 911?
As a Tripadvisor reviewer of a Texas Urban Air noted, some parks have a policy to downplay injuries and avoid 911 calls. If the park refused to call for help, we treat that as evidence of conscious indifference to your child’s safety—a direct path to punitive damages.

The Silent Epidemic: Why We Publish This Guide
Every parent we talk to expresses the same regret: “We had no idea.”
They had no idea that foam pits are often compacted to four inches when the standard requires eight. They had no idea that the “monitor” was a seventeen-year-old on his fourth shift who received only two hours of orientation. They had no idea that the “safest” trampoline was one an industry lobbyist had authorized for use against a quarter-century of medical warnings.
We publish this information for Sandy Oaks because knowledge is the only thing that levels the playing field against national chains backed by multi-billion dollar private equity firms.
What happened to your child at the park near Sandy Oaks wasn’t an accident. It was the predictable output of a business model that treats your child’s safety as a variable expense.
ASTM F2970 exists because the industry needed a floor. The park operated below that floor to hit a revenue goal. The waiver was drafted by corporate counsel who knew it wouldn’t hold in most Texas courts, but hoped it would stop you from calling a lawyer. The surveillance is engineered to overwrite before you have a chance to see what really happened.
We were built for exactly this. We have the credentials, the courtroom experience, and the insider knowledge to pierce the corporate shield and hold every layer of the defendant stack accountable.
One bounce changed your family’s life. One phone call can start the process of putting it back together.
