At the Altitude Trampoline Park on Belt Line Road in Cedar Hill, or perhaps at one of the nearly thirty Urban Air or Sky Zone locations dotting the Dallas-Fort Worth Metroplex, a Saturday afternoon meant to celebrate a birthday can turn into a life-altering medical crisis in as little as eight minutes. For many Cedar Hill families, the experience ends not with a cake and party favors, but with what Kaitlin “Kati” Hill described to ABC News as “the worst scream that you could ever have heard from a child.” Her three-year-old son Colton suffered a broken femur that required him to spend months in a body cast. Kati’s admission — “We had no idea” — is a sentiment we hear echoed in hospital rooms across North Texas.
We are Attorney911, The Manginello Law Firm. For more than 25 years, our managing partner Ralph Manginello has stood in the gap for families facing catastrophic injuries that never should have happened. From our base in Texas, we have litigated against the largest corporate entities in the world, including the multinational conglomerates involved in the BP Texas City refinery explosion. We bring that same fearlessness to the trampoline industry. Whether your child was injured at a commercial facility in Cedar Hill or on a defective backyard trampoline in one of our beautiful southwest Dallas County neighborhoods, we understand the physics of the impact, the medicine of the recovery, and the corporate shields the industry uses to hide from accountability.
The parent sitting at the bedside in the level 1 pediatric trauma center at Children’s Medical Center Dallas or Cook Children’s in Fort Worth doesn’t need a generalist. You need a team that knows exactly why the trampoline park’s insurance adjuster is calling you with a “friendly check-in” and a $3,000 check. You need a lawyer like our associate Lupe Peña, who used to sit on the other side of the table defending insurance companies and recreational businesses. He knows the playbook they are using in your case because he helped write it. Today, he uses that insider knowledge to dismantle those very same defenses for Cedar Hill families.
The Reality of the Cedar Hill Trampoline Environment
Cedar Hill is a community defined by its active youth culture and outdoor lifestyle. From the competitive cheer programs that utilize tumble tracks to the standard backyard trampolines found in neighborhoods near Cedar Hill State Park or Joe Pool Lake, our children are airborne every single day. Nationally, trampolines send over 300,000 Americans to the emergency room every year. In a metroplex as saturated as Dallas-Fort Worth, those statistics are measured in hundreds of families every month.
The commercial trampoline park industry has grown into a multi-billion-dollar sector, but it remains a regulatory “Wild West.” In Texas, there is no state-level law specifically mandating safety inspections for trampoline decks. While the Texas Department of Insurance regulates “Class B” inflatable rides under Texas Occupations Code Chapter 2151 — such as the bungee trampolines or indoor coasters you might find at an Urban Air — the trampolines themselves are statutorily excluded. This creates a massive safety gap. At Attorney911, we close that gap by holding these parks to the standards they wrote for themselves.
The industry established ASTM F2970 as a voluntary safety floor, covering everything from attendant-to-jumper ratios to foam pit depth. When a Cedar Hill park operator chooses to staff a peak Saturday shift at half the required ratio to protect their margin, they aren’t just being “careless.” They are making a business decision that prioritizes profit over your child’s spinal cord. We treat it as exactly that: an actionable breach of the standard of care.
Cedar Hill Geographic Focus and Regional Safety Patterns
When we investigate a case for a Cedar Hill resident, we look at the entire regional ecosystem. Families in southwest Dallas County often frequent the Altitude Trampoline Park on the north side of Belt Line Road, but the reach extends to the Urban Air locations in Mansfield and Waxahachie or the Sky Zone parks in Irving and Arlington. Each of these parks is part of a larger corporate tower.
Effective January 1, 2023, the entity formerly known as CircusTrix LLC renamed itself Sky Zone, Inc. Backed by Palladium Equity Partners, this conglomerate now parents the Sky Zone, DEFY, and Rockin’ Jump brands. Similarly, Unleashed Brands — the parent of Urban Air — was acquired by Seidler Equity Partners in early 2023. When we say we hold a local park accountable, we mean we trace the liability through the operator LLC, up through the franchisee, to the franchisor, and finally to the private equity sponsors who ultimately approve the budgets.
Our firm has office locations in Houston, Austin, and Beaumont, and we are built to handle cases throughout Cedar Hill and the entire state of Texas. We advance every expense of your litigation — including the retention of world-class biomechanical engineers and pediatric orthopedic consultants — because your child’s recovery fund should not be strained by the cost of justice.
The Meta-Narrative: This Was Never an Accident
There is a dangerous myth in the recreational industry that injuries are “just part of the fun” or “unfortunate accidents.” We reject that framing. The American Academy of Pediatrics (AAP) has formally advised against recreational trampoline use since 1999. They reaffirmed that position in 2012 and again in 2019. This means for over a quarter-century, the medical consensus has been clear: trampolines are fundamentally unsafe for children.
Manufacturers and park operators know this. They sell the product and the experience anyway. Every time a child in Cedar Hill is double-bounced and suffers a comminuted femoral shaft fracture, it is the result of a predictable sequence of events. The park knew the risk, they knew the standard (one jumper per bed), and they failed to enforce it.
One of our strongest local precedents is the Max Menchaca case against Cosmic Jump in Harris County. A sixteen-year-old fell through a torn trampoline slide onto concrete, resulting in a traumatic brain injury. Despite a signed waiver, the jury found gross negligence and awarded $11.485 million, including $6 million in punitive damages. That verdict is the largest reported jury award against a U.S. commercial trampoline park, and it happened right here in a Texas courtroom. It proves what we tell every client: the piece of paper you signed at the kiosk is not a wall; it is a hurdle we are built to clear.
Understanding the “Waiver” Deception in Texas
If you are a parent in Cedar Hill who signed an iPad waiver and now feels like you have no recourse, you need to understand Texas Law. Our team, led by Ralph Manginello, specializes in the five-vector attack on these agreements.
1. The Minor Child Rule (Munoz v. II Jaz)
In Texas, the landmark case of Munoz v. II Jaz, Inc. (1993) established that a parent cannot pre-emptively waive a minor child’s personal injury claim against a commercial operator. While a 2025 Texas Supreme Court ruling in Cerna v. Pearland Urban Air allowed delegation clauses to send certain disputes to arbitration, the substantive right of the child to seek recovery remains protected under Texas public policy.
2. The Fair Notice Doctrine
Under Dresser Industries v. Page Petroleum, a waiver in Texas must meet two strict standards:
- The Express Negligence Doctrine: It must specifically use the word “negligence.”
- Conspicuousness: The release language must be bold, distinguishable, and attract the attention of a reasonable person.
If the kiosk waiver you signed at a Cedar Hill park was a 20-page scroll-down field on a tablet, it likely fails this test.
3. The Gross Negligence Carve-Out
No waiver in Texas can release a defendant from “gross negligence.” Under the Moriel standard, if an operator has subjective awareness of an extreme risk and proceeds with conscious indifference, your waiver stops being a shield. We look for the “smoking gun” in their internal records — the daily inspection log that was signed but never performed, or the franchisor audit that flagged understaffing months before your child was hurt.
4. Direct-Benefits Estoppel and Signer Authority
Texas Family Code § 153.073 states that only a parent or court-appointed conservator has the authority to sign for a child. At Cedar Hill birthday parties or multi-generational outings at Joe Pool Lake-adjacent rentals, a grandparent, aunt, or family friend often signs the waiver. In those cases, the waiver’s footing as to the child is destroyed before we even get to the merits of the case.
Accident Mechanisms: The Physics of Cedar Hill Injuries
We retain biomechanical engineers to model exactly how Cedar Hill injuries occur. The physics are often more violent than parents realize.
The Double-Bounce Multiplier
This is the most common mechanism at parks like Altitude or Sky Zone. When an adult lands on a trampoline bed while a child is pushing off, the energy transfer multiplies the child’s launch force by up to four times. The child isn’t just jumping; they are being catapulted. This produces “trampoline fractures” of the proximal tibial metaphysis or catastrophic femur breaks.
Foam Pit cervical Hazards
Foam pits look like harmless clouds, but they are a primary source of cervical spine injuries. If the foam blocks are compressed or the pit is shallow — a violation of ASTM F2970 — a head-first entry results in axial loading. We have seen cases of SCIWORA (Spinal Cord Injury Without Radiographic Abnormality) where a child’s CT scan looks “normal” but the cord is ischemic. If your child was told they were “fine” and should “walk it off” after a foam pit fall at a DFW park, you need an attorney who understands pediatric neuro-pathology.
Harness and Attraction Failure
As Cedar Hill parks shift toward the families-entertainment center (FEC) model, we see a rise in injuries from ropes courses, climbing walls, and ziplines. The Ispahani family suit in Sugar Land is a warning to every Cedar Hill parent: an attendant can strap a harness on a child but fail to attach the safety line. A fall from thirty feet onto unpadded concrete is lethal head trauma waiting to happen, as seen in the Matthew Lu case at Altitude Gastonia.
The Evidence Clock: Why the Next 7 Days are Critical
While the Texas statute of limitations generally gives you two years to file a claim, the evidence you need to win will vanish long before then.
- Surveillance DVRs: Most Cedar Hill area parks have systems that overwrite video every 7 to 30 days.
- Incident Reports: Metadata shows that parks often “revise” or sanitize their reports 48 to 72 hours after the injury.
- Kiosk Versions: Many parks run waiver software that purges specific version history on a rolling 72-hour cycle.
When you retain Attorney911, our spoliation letter goes out by certified mail and email to the park and its franchisor within 24 hours. We demand the preservation of not just the video, but the time-clock records, the training files of the monitors on duty, and the daily pre-opening inspection logs. If the park’s video “glitches” at the moment of injury — as happened in the Mathew Knight case in Georgia that resulted in a $3.5 million verdict — we are prepared to move for an adverse inference instruction.
Catastrophic Pediatric Injuries: Beyond the Emergency Room
A broken bone in a Cedar Hill eight-year-old is not the same as a broken bone in an adult. We focus on the pediatric development multiplier.
Salter-Harris Growth Plate Fractures
The growth plates at the ends of a child’s bones are more pliable than the bone shaft but much more vulnerable. A Salter-Harris Type II fracture of the distal tibia can result in limb-length discrepancy that doesn’t fully manifest until the child is thirteen or fourteen. If your lawyer doesn’t understand the need for a a decade of orthopedic monitoring, they are leaving millions on the table.
The Rhabdomyolysis Risk
We are the only North Texas firm with an active $10 million medical-litigation architecture for rhabdomyolysis. Currently litigating a case involving the University of Houston, we understand the pathophysiology of muscle cells rupturing and dumping myoglobin into the bloodstream. A child jumping continuously for 90 minutes in a heated indoor park in the middle of a Texas summer can arrive at the ER in acute kidney failure 48 hours later. We know how to document this “cola-colored urine” cascade and hold the institutional defendant accountable.
Why Choose Us for Your Cedar Hill Case?
We recognize that you have choices. You might be considering a large-volume firm with billboard advertisements. But here is the “moat” that protects Attorney911 clients:
- Lupe Peña’s Defense Edge: We know the insurance company’s internal script because Lupe used to follow it. He knows when an adjuster is bluffing about policy limits.
- Fortune 500 Experience: Ralph Manginello’s history in the BP refinery litigation means we are not intimidated by the private equity giants behind Sky Zone, Urban Air, or Altitude.
- The 50-State Research Moat: Our firm maintains a 50-state database of waiver enforceability and parental indemnity. Whether the injury happened in Cedar Hill or while on vacation in Florida or California, we know the local precedent.
- Hablamos Español: Lupe Peña represents our clients directly in Spanish. We understand the Dallas County demographic. If your family’s primary language is Spanish and the park only gave you an English waiver, the Delfingen doctrine may void that agreement entirely.
Frequently Asked Questions for Cedar Hill Parents
How much does a trampoline injury lawyer cost?
Nothing upfront. We work on a pure contingency fee — 33.33% pre-trial or 40% if we go to a jury. We advance all costs for biomechanists and pediatric specialists. If we don’t recover money for your child, you owe us zero dollars for fee or expense.
Can I sue if my neighbor’s kid was hurt on our backyard trampoline?
Texas follows the “attractive nuisance” doctrine. If an artificial condition like a trampoline attracts kids of “tender years” who cannot appreciate the danger, the homeowner can be liable. We look at your homeowners’ policy to see if a trampoline exclusion exists, then look to the manufacturer (like Jumpking or Skywalker) for product defect potential.
What should I do if the park manager tells me not to call 911?
Call 911 yourself immediately. The “Don’t Call 911” protocol is a documented industry tactic used to minimize evidence. The Urban Air Southlake parent review confirmed this is a systemic management instruction. Your family’s safety comes before the park’s PR.
Is it too late if I didn’t take photos of the court?
No, but it makes the DVR footage more critical. We send forensic investigators to Cedar Hill parks to document current conditions and compare them to the standard of care.
What is a “Life-Care Plan”?
For catastrophic labels like paralysis or severe TBI, a medical bill is just the beginning. We produce a comprehensive Life-Care Plan that forecasts every cost for the next 70 years of your child’s life — from wheelchair replacements every 5 years to lifetime attendant care. This is how we anchor our multi-million-dollar demands.
Cedar Hill and Dorth Central Texas Case Anchors
We believe in accountability. Whether it is the $15.6 million Damion Collins award or the $11.485 million Cosmic Jump verdict, the pattern is the same: children are hurt when adults fail to follow the rules they wrote.
If your family is in Cedar Hill, Duncanville, DeSoto, or the surrounding communities, and your life changed in one bad landing, we are ready to fight. We represent families. We represent the parent who watches the surgeon and wonders what the future looks like. We are your voice in the courtroom and your shield against the insurance companies.

Detailed FAQ: Tactical Information for Families
“Can I sue if I signed the waiver?”
Yes. This is the question that keeps most Cedar Hill parents from calling a lawyer. The truth is that in Texas, waivers are highly scrutinized. Between the Munoz rule for minors and the Dresser requirement for express negligence, most “iPad waivers” are full of holes. Even if the waiver is technically valid, it cannot cover gross negligence. In Harris County, the Cosmic Jump verdict of $11.485M happened despite a signed waiver because the park knew the equipment was broken and let kids jump anyway.
“Should I take my kid to a trampoline park at all?”
The American Academy of Pediatrics says no. As attorneys who handle these cases, we advise parents to look for the “red flags” we detailed earlier. If the park is understaffed, if the mats are torn, or if you see adults jumping next to toddlers — walk out.
“My kid broke a bone at Altitude Cedar Hill. What do I do?”
Seek immediate pediatric orthopedic care. Document the location of the break. Specifically, ask the doctor if the “growth plate” is involved. Once the child is stable, your only job is evidence. Preserve the wristband, keep the socks, and call an attorney to freeze the surveillance video. Avoid talking to the Altitude risk management team or their insurer.
“How do I tell if they were negligent vs. just an accident?”
The industry wants you to believe injuries are unavoidable. We prove negligence by showing the park fell below the “floor” of ASTM F2970. Did they have one monitor for 60 kids? Did they fail to rotate the foam pit blocks? Did they let 200lb adults bounce on a bed with a 50lb toddler? If they violated a standard, it wasn’t an accident — it was negligence.
“They wouldn’t call 911 — is that legal?”
It is an extremely dangerous pattern. In Texas, failing to seek aid for an invitee can be a major liability hook. Multiple reviews at locations like Urban Air Southlake allege that monitors are told to “downplay” injuries to avoid an ambulance bill. If this happened to you in Cedar Hill, it is evidence of a conscious disregard for your child’s safety — the definition of gross negligence.
“What is a ‘double bounce’ and why is everyone talking about it?”
It is a transfer of energy. When two people land at different times, the larger person’s weight “loads” the mat, and when it snaps back, it launches the smaller person with up to 4x the force. This is precisely why the Nysted ratio says a toddler is 14 times more likely to break a bone when jumping with an adult.
“How long do I have to do something — is there a deadline?”
Legally, two years. Practically, two weeks. After thirty days, many parks in the DFW area have already cleared their digital storage. If you don’t send a formal spoliation letter, you are trusting the people who hurt your child to keep the proof of how they did it.
“What if I didn’t actually sign — my in-laws or the friend’s parent did?”
Then the waiver is likely worthless to the park. Under Texas Family Code § 153.073, only a legal guardian has the power of “substantial legal significance” regarding a child’s rights. A friend’s parent cannot sign away your right to recover for your son’s broken back.
“Will I be blamed or called a bad parent for taking them there?”
The park’s defense lawyer will try this tactic in court. It’s called “contributory negligence.” In Texas, as long as the park’s negligence is greater than yours, they still pay. And more importantly, as you just read, thousands of parents bring their kids to Cedar Hill parks every weekend because they trust the marketing that says “safe family fun.” The guilt belongs to the park that marketed safety while cutting the staffing budget.
“What if the park is a franchise — can we still sue corporate?”
Absolutely. Under the Sampson doctrine in Texas, we use “apparent agency.” The park uses the logos, the colors, the uniforms, and the brand of the franchisor. You went there because you trusted the Sky Zone or Urban Air name. The franchisor controls the manuals and the training, and in the $15.6M Damion Collins award, the franchisor (UATP Management) was hit with 40% of the fault.
