“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 how Kaitlin “Kati” Hill described the moment her three-year-old son Colton’s life changed at a “toddler time” session. She told ABC News that despite the marketing, she had no idea of the risk. We hear these stories every day at our firm. From the suburban backyards of The Tribute and Austin Waters in City of The Colony to the packed courts of the commercial trampoline parks along the Sam Rayburn Tollway, the “worst scream” is a sound we are dedicated to answering with accountability.
What happened to your child in City of The Colony wasn’t an accident. It was the predictable output of a system designed to prioritize throughput and margin over pediatric safety. Whether the double-bounce happened at a Launch in Lewisville, an Urban Air in Frisco, or a Sky Zone in Irving, the legal architecture of the case is the same. The American Academy of Pediatrics (AAP) has been warning parents since 1999 that trampolines don’t belong at home. In 2012 and 2019, they reaffirmed that recreational trampoline use remains fundamentally unsafe for children. Yet, manufacturers like Jumpking and Skywalker continue to fill City of The Colony backyards with polypropylene nets and false promises of safety.
We are Attorney911. Our founder, Ralph Manginello, has spent 25+ years in federal and state courts making corporate defendants pay for catastrophic injuries. We’ve litigated against Fortune 500 giants like BP, Walmart, and Amazon. We’ve managed complex lawsuits with 13 or more defendants, like our current $10 million lawsuit against the University of Houston involving rhabdomyolysis and acute kidney failure. We bring that same institutional-accountability framework to City of The Colony trampoline injury cases. When your child is in the trauma bay at a facility like Children’s Medical Center Plano or Cook Children’s Prosper, you don’t need an attorney who “handles personal injury.” You need a firm that has memorized ASTM F2970 Section 10, that knows exactly how to pierce the five-layer corporate stack of companies like Sky Zone, Inc. and Unleashed Brands, and that includes an attorney like Lupe Peña, who used to defend these very companies. He knows their playbook because he helped write it. Now, he uses it to beat them.
The Physics of a City of The Colony Trampoline Injury
If you are a parent in City of The Colony, you might have been told that your child “just landed wrong.” That is the park’s narrative. The legal reality is dictated by physics and industry standards. Most injuries on the courts serving City of The Colony are caused by energy transfer—the “double-bounce.” This occurs when a heavier jumper lands while a lighter child is pushing off. The rebound bed acts as a catapult, multiplying the child’s launch force by up to 4x. This isn’t speculation; it is established biomechanics documented by experts like Eager in Sports Engineering (2012).
ASTM F2970-22 is the industry’s own safety floor. It was written by trampoline park operators themselves to establish minimum standards for court-monitor ratios and age separation. When a park ignores these rules during a busy Saturday afternoon birthday party near the Sam Rayburn Tollway, they aren’t being “careless.” They are committing gross negligence—the conscious disregard of a known, extreme risk. In Texas, we look at the 2018 Harris County case against Cosmic Jump. Sixteen-year-old Max Menchaca fell through a torn slide onto concrete and suffered a traumatic brain injury. Even though a waiver was signed, the jury awarded $11.485 million, including $6 million in punitive damages. Why? Because the park had actual knowledge of the rip and chose indifferently to keep the court open.
In City of The Colony, we apply that same pressure. We look for the “surveillance glitch” pattern seen in the Mathew Knight case in Georgia, where four cameras magically failed at the exact moment of injury, leading to a $3.5 million verdict. We look for the “Don’t Call 911” protocol documented in Texas at Urban Air locations, where employees were reportedly instructed to downplay injuries and avoid emergency dispatches. These aren’t isolated mistakes; they are cultural choices.
Piercing the Corporate Shield of Sky Zone, Urban Air, and Altitude
When we say we sue a chain, we are actually performing “corporate archaeology.” “Sky Zone” or “Urban Air” isn’t just one company in City of The Colony. It is a stack of entities designed to shield the deep pockets from the families they injure.
- The Operator LLC: The specific entity running the park in Lewisville or Frisco. Often undercapitalized with a $1M policy.
- The Franchisee: A multi-unit ownership group that may own several parks across Denton County.
- The Franchisor: Entities like Sky Zone Franchising LLC or UATP Management LLC. They dictate the training and safety standards.
- The Corporate Parent: Sky Zone, Inc. (formerly CircusTrix LLC), backed by Palladium Equity Partners; or Unleashed Brands, acquired by Seidler Equity Partners in 2023. These are massive conglomerates with Sales exceeding $642M annually.
- The Private Equity Sponsor: The ultimate money behind the margin-driven decisions to cut staffing ratios.
Our firm is uniquely suited to navigate this stack. Because Lupe Peña formerly sat on the defense side, he understands how franchisor additional-insured provisions work. We don’t settle for the local LLC’s meager policy. We follow the control. If the franchisor retained control over the safety manuals or training protocols—as was the case in the $15.6M Damion Collins quadriplegia award against Urban Air Overland Park—we make the corporate parent pay. In that Kansas arbitration, Arbitrator Thomas Bender held the waiver unenforceable due to “systemic failure” by the franchisor (UATP Management) to implement safety changes.
The State of the Law in Texas: Your Waiver Isn’t a Wall
You probably signed a waiver on an iPad kiosk before your child entered the park. The manager in City of The Colony might have told you that paper means you can’t sue. They are wrong. Under Texas law, multiple attack vectors exist to dismantle that signature.
The Munoz Doctrine: Parental Indemnity Is Void
Since the landmark 1993 case Munoz v. II Jaz, Inc., Texas courts have held that a parent cannot bind a minor child to a pre-injury release of the child’s prospective tort claims. While the Texas Supreme Court recently decided Cerna v. Pearland Urban Air (May 2025), which enforced an arbitration delegation clause, the underlying substantive claim of the child typically survives. Your signature may bar your own derivative claims for medical bills, but it cannot legally extinguish your child’s right to seek justice for a broken neck or a destroyed growth plate.
The Dresser “Fair Notice” Requirement
In Dresser Industries v. Page Petroleum (1993), the Texas Supreme Court established the “Fair Notice” doctrine. For a release of negligence to be valid, it must be Express (using the word “negligence” specifically) and Conspicuous (formatted to attract the attention of a reasonable person). Kiosk waivers that bury release language in 20 screens of text often fail this test.
Bilingual Formation and the Delfingen Attack
City of The Colony is a diverse community. If your family’s primary language is Spanish and the park presented an English-only iPad waiver under pressure, you may have a formation defense. The Delfingen US-Texas v. Valenzuela (2013) ruling allows courts to void agreements where a language barrier prevents meaningful assent. Lupe Peña speaks Spanish natively; she handles these conversations directly—”Hablamos Español. Llame al 1-888-ATTY-911.”
The Medical Reality: Children’s Bones and Spinal Cord Strokes
Most personal injury firms treat a trampoline injury like a car wreck. We treat it like the distinct pediatric pathology it is. Children’s bones are biomechanically distinct—they are more pliable, with open growth plates (physes) that are weaker than the surrounding joint.
- Salter-Harris Fractures: A fracture through the growth plate at age 8 can lead to a limb-length discrepancy that doesn’t manifest until age 14. If your attorney doesn’t build a 10-year orthopedic monitoring budget into your demand, they are leaving your child’s future on the table.
- SCIWORA (Spinal Cord Injury Without Radiographic Abnormality): This is a pediatric phenomenon where the cord is injured despite “normal” CT scans. We’ve seen this in head-first foam pit entries across North Texas.
- Vertebral Artery Dissection: The mechanism made famous by the Elle Yona TikTok (27 million views). A rotation in a foam pit can tear the artery, causing a spinal cord infarction (stroke). In the Miami case, it was initially misdiagnosed as a panic attack. We represent parents whose “headache” at a City of The Colony park was actually a neurovascular emergency.
- The Rhabdo Bridge: If your child jumps for 90 minutes in a hot City of The Colony facility and arrives at the park with dark brown urine or listlessness 24 hours later, this could be exertional rhabdomyolysis. We are currently litigating a $10M case involving this exact pathology. We know the myoglobin cascade and the dialysis risk better than any other firm in Texas.
Adjacent Attractions: The Dangerous “FEC” Pivot
Trampoline parks near City of The Colony are increasingly “bolting on” dangerous attractions designed by third-party manufacturers. These are no longer just jumping facilities; they are Family Entertainment Centers (FECs).
- Sky Rider & Indoor Coasters: We track the Urban Air Sky Rider strangulation pattern across Newnan, Bloomingdale, and Florida. A harness cord can becoming a ligature in seconds.
- Climbing Walls over Concrete: The Matthew Lu (Altitude Gastonia) fatality was caused by a fall onto unpadded concrete. More recently, in 2022, a 14-year-old at the Sugar Land Urban Air (Lakhani case) fell 30 feet because an attendant failed to attach the fall-protection equipment.
- Go-Kart Malfunctions: The Emma Riddle (2025) fatality in Port St. Lucie involved a go-kart that surged forward into a wall. The multi-attraction model means one undertrained attendant is often watching four different motorized or harness-based features at once.
Preserving Evidence: The 72-Hour Evidence Clock in City of The Colony
Your child’s case is decided by what happens in the first week. While the Texas statute of limitations provides two years, the evidence clock in City of The Colony is much more urgent.
- Surveillance Overwrite: Most DVR systems at parks near Lewisville and Frisco overwrite in 7 to 30 days. If you don’t have a spoliation letter on their desk by Day 5, the footage of the double-bounce is gone.
- Incident Report Revisions: Parks “finalize” their reports (meaning they sanitize them) within 48 hours. We demand the native metadata to see every edit made after our client was injured.
- Attendant Turnover: The person who saw your son’s leg break was likely a 17-year-old who will quit or transfer within 3 months. Our ex-employee outreach protocol uses LinkedIn alumni searches and labor records to find these witnesses before the defense “preps” them.
- Foam Pit Remediation: A “shallow” foam pit will be refilled the moment a claim is anticipated. We deploy biomechanical engineers within 48-72 hours to measure the depth and compaction.
We advance every expense. We pay for the Life Care Planner who builds the 60-year medical forecast for your daughter. We pay for the forensic digital examiner to interrogate the DVR. You pay nothing unless we win.
Frequently Asked Questions for City of The Colony Families
Can I sue if I signed the iPad waiver at the park?
Yes. As outlined in our Texas deep-dive, waivers are not absolute shields. In most states, they cannot legally bind a minor child’s personal claim. Furthermore, Texas “Fair Notice” rules and gross negligence carve-outs—proven by the Cosmic Jump $11M verdict—mean the paper you signed is often just noise. We attack on five separate vectors, including unconscionability and scope of the “inherent risk.”
What should I do if my child has dark urine after a trampoline park visit?
Go to the emergency room at a Level 1 pediatric center like Children’s Medical Center Dallas immediately. This is a sign of rhabdomyolysis—muscle tissue breaking down and poisoning the kidneys. Mention our active $10M university rhabdo case to any doctor; we have established the medical-litigation architecture for this exact emergency. Do not wait for symptoms to improve.
The park only has a $1 million insurance policy. Is that all I can recover?
No. The $1M policy is usually just the primary layer of the local operator LLC. Above that sits the franchisee’s umbrella, the franchisor’s additional-insured coverage, and the corporate parent’s (Sky Zone, Inc. or Unleashed Brands) excess tower. For national chains, the total coverage can exceed $50 million. Most generalist firms never look past the first million. We do.
What if my child’s injury happened at an Urban Air or Altitude birthday party?
The birthday party host contract is a separate legal event. If you were a guest and didn’t sign the kiosk waiver, but the host parent signed a master agreement, the park has no waiver coverage against you at all. This is one of the many “gap exploits” our firm identifies on Day 1.
How much does it cost to hire Attorney911?
Zero upfront. We work on a contingency fee basis. Our interests are perfectly aligned with your child’s recovery. We advance the costs for the pediatric orthopedic surgeons, the accident reconstruction experts, and the digital forensics teams. If we don’t recover money for you, you owe us nothing.
Why was my child told they had a “panic attack” when it was a spinal cord stroke?
Vertebral artery dissection is frequently misdiagnosed because it presents atypically in young people. The Elle Yona TikTok case proves this misdiagnosis pattern exists even at major trauma centers. If the park failed to provide staff trained in neurovascular recognition or refused to call 911 (the “NOT call 911” Urban Air Southlake pattern), they are legally responsible for the delayed care that worsens the stroke outcome.
What is a “Salter-Harris” fracture and why is everyone talking about it?
It is the medical classification for a growth plate fracture. Because your child’s bones are still growing, a break “on the line” can cause the bone to stop growing or grow crooked. The true damage may not be measurable for 4 to 6 years. We use Certified Life Care Planners to forecast the surgical correction your child will need at age 14, ensuring the settlement handles the future, not just the past co-pay.
How long do I have to take action?
The statute of limitations in Texas is two years, but the evidence disappears in 7 days. Every minute you wait to send a spoliation letter is a minute the park’s DVR gets closer to overwriting your daughter’s accident. Call 1-888-ATTY-911 today.
