“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 suffered a broken femur at a trampoline park, telling ABC News about the moment her life changed. In City of Saginaw, we see this story repeated in trauma bays and orthopedic clinics more often than the industry would ever care to admit.

Every parent who takes their child to a trampoline park in City of Saginaw does exactly what you did. You signed the document at the kiosk because the line was long and the kids were excited. You handed over the wristband because you wanted them to have fun. You assumed that because the facility was open for business and filled with other City of Saginaw families, it was reasonably safe.

But what happened to your child at an Urban Air, a Sky Zone, or an Altitude park near City of Saginaw wasn’t an accident—it was the predictable output of a system. The American Academy of Pediatrics has been warning since 1999 that trampolines do not belong in recreational centers or homes. ASTM F2970 was written by the trampoline park industry itself to establish a minimum safety floor, and yet, day after day, parks operate below that floor to hit a profit margin. The waiver you signed was drafted by corporate lawyers who knew it wouldn’t hold up in a Texas court for gross negligence, but they counted on you not knowing that.

We are Attorney911, The Manginello Law Firm. Our managing partner, Ralph Manginello, has spent over 25 years holding corporate giants accountable. We have gone toe-to-toe with Fortune 500 companies like BP, Walmart, and Amazon. Our team includes Lupe Peña, an attorney who used to sit on the other side of the table defending insurance companies and recreational facilities. He knows their playbook because he helped write it. Now, he uses that insider knowledge to dismantle the exact defenses these parks use against City of Saginaw families.

We represent the parent at the trauma-bay bedside watching a surgeon explain what happens when a growth plate is destroyed at age nine. We currently litigate a $10 million lawsuit involving rhabdomyolysis and acute kidney failure—the same catastrophic muscle and organ breakdown we see in children who are overworked and dehydrated at indoor jump facilities in the Texas heat.

If your child was injured, the clock is already running on the evidence. DVR systems in these parks often overwrite in as little as 7 to 30 days. Incident reports get “revised” by management. Attendants who saw what happened quit or transfer. We are built for this fight.

The Trampoline Injury Reality in City of Saginaw and Tarrant County

City of Saginaw sits in the heart of one of the most saturated trampoline park markets in the world. With Urban Air headquartered just down the road in Grapevine and Altitude Trampoline Park based in Fort Worth, our local area is the testing ground for every new attraction and every cost-cutting staffing measure the industry tries.

A Fort Worth Star-Telegram investigation uncovered a staggering number: 500 injury reports at 21 trampoline parks in the Dallas-Fort Worth metro over just seven years. In City of Saginaw, your child might have been jumping at the Urban Air in Southlake—the same location where a parent famously reported on Tripadvisor that employees are specifically instructed by management to NOT call 911 and to downplay injuries. Or perhaps they were at an Altitude park in Fort Worth or a Sky Zone near I-35W.

Regardless of the brand, the physics remains the same. When your daughter is jumping in an area with 50 other kids and a 200-pound adult lands on the same mat while she is pushing off, the energy transfer multiplies her launch force by up to four times. She isn’t jumping anymore; she’s a projectile. This mechanism, known as a “double-bounce,” causes the majority of the broken femurs and shattered tibias we see.

The industry tells City of Saginaw parents that these are “inherent risks.” We disagree. It is not an inherent risk for an attendant to be on their phone while an adult double-bounces a child. It is not an inherent risk for the foam pit to be compacted to four inches of clearance when ASTM F2970 requires much more. These are choices.

Why the Waiver Is Not a Wall in City of Saginaw

The most common reason parents wait to call an attorney is that they believe the waiver they signed at the kiosk ended their case. In City of Saginaw, and throughout Texas, that simply isn’t true.

Texas law is very specific about what a waiver can and cannot do. First, as the landmark case Munoz v. II Jaz, Inc. (1993) established right here in the Houston-area appellate courts, a parent cannot sign away a minor child’s personal injury cause of action. Your signature may affect your own right to sue for medical bills, but your child’s right to be made whole for their pain, suffering, and permanent impairment remains intact.

Second, Texas courts have repeatedly held that a waiver cannot shield a park from gross negligence. Look at the Cosmic Jump verdict in Harris County. A 16-year-old fell through a torn trampoline slide onto concrete and suffered a traumatic brain injury. The park had a signed waiver. The jury awarded $11.485 million anyway—including $6 million in punitive damages—because the park knew the equipment was torn and chose to leave it in service.

Our team, led by Ralph Manginello with his 25+ years of experience, understands the Dresser v. Page Petroleum fair notice doctrine. We look at whether the waiver was conspicuous or if the “negligence” language was buried in a way that wouldn’t attract a reasonable person’s attention. If your family’s primary language is Spanish and you were presented with an English-only iPad waiver at a busy City of Saginaw park, the Delfingen US-Texas v. Valenzuela doctrine may render that waiver void for lack of valid formation.

Most personal injury firms read the waiver and give up. We read the waiver and find the holes. Call us at 1-888-ATTY-911 to discuss why that piece of paper doesn’t prevent your family from seeking justice.

Catastrophic Pediatric Injuries: Beyond the ER Bill

When a child is hurt at a trampoline park in City of Saginaw, the medical bills you see today are just the beginning. We don’t view your child’s case through the lens of a single hospital visit. We view it through the lens of their entire developing life.

Growth Plate (Salter-Harris) Fractures

A “broken ankle” in an eight-year-old is almost never just a broken ankle. It is often a Salter-Harris fracture, an injury to the growth plate. If that plate is destroyed, the bone may stop growing or grow crooked. Your child may not show a limb-length discrepancy until they are 14, at which point the park will argue it had nothing to do with the trampoline. We retain pediatric orthopedic surgeons to testify about exactly what that growth plate needs for the next decade.

Traumatic Brain Injury (TBI)

Whether it’s a head-to-head collision or a fall through a torn mat onto concrete, a TBI in a developing brain is devastating. We have recovered multi-million dollar settlements for victims of traumatic brain injuries. We understand “diffuse axonal injury”—the shearing of brain fibers that often doesn’t show up on a standard CT scan. If your child has been “different” since the accident—more irritable, struggling in school, or experiencing headaches—you need the experts we provide.

SCIWORA and Cervical Spine Injuries

Children’s spines are ligamentous and flexible. They can suffer SCIWORA—Spinal Cord Injury Without Radiographic Abnormality. A child lands head-first in a foam pit at a Saginaw-area park, the ER says the X-ray is normal, and six hours later, the child loses feeling in their legs. The cord is injured even when the bones aren’t broken. This is why our founder, Ralph Manginello, insists on immediate, high-level neurological evaluations for our clients.

Exertional Rhabdomyolysis

A child jumping in a 90-degree indoor park for two hours without adequate water is at risk for rhabdo. Their muscle tissue breaks down and floods the kidneys with myoglobin. Our active $10 million lawsuit against the University of Houston for rhabdomyolysis gives us a medical-litigation architecture that no other firm can match. We know the myoglobin cascade, we know the nephrology experts, and we know how to prove the park’s hydration and temperature failures caused your child’s kidney failure.

We represent families in City of Saginaw who are standing at a hospital bedside. We take the financial burden off your shoulders by advancing every cost—the biomechanical engineer, the life-care planner, the orthopedic consultant. You pay us nothing unless we win.

The 48-Hour Evidence Crisis in Trampoline Litigation

The single biggest mistake families make after an injury at a park like Urban Air or Sky Zone near City of Saginaw is waiting to hire a lawyer. While you are focused on your child’s surgery, the park’s risk management team is already focused on the defense.

Surveillance video is the lifeblood of a trampoline case. Most of these parks use digital video recorders (DVRs) that automatically overwrite old footage on a 7 to 30-day cycle. If you wait 31 days to call us, the video of the attendant on his phone while your son was double-bounced is gone forever.

Our firm doesn’t wait for the litigation process to start. Our spoliation letter goes out via certified mail within 24 hours of you hiring us. We demand the preservation of:

  • All multi-angle surveillance footage (not just the “clip” the park wants us to see).
  • The original incident report and every “revised” version in their computer system.
  • Attendant time-clock and training records.
  • The maintenance logs for the specific trampoline or foam pit involved.
  • The waiver database metadata—to prove what version you actually signed.

When a park tells us the video “glitched” or is “unavailable,” we don’t just take their word for it. We remember the Mathew Knight case in Georgia, where a jury awarded $3.5 million because the park’s surveillance happened to fail on four different cameras at the exact moment of the injury. We hire digital forensic examiners to interrogate their hard drives.

Do not let the park’s silence or the insurance adjuster’s “friendly checkout” fool you into waiting. The evidence is disappearing in City of Saginaw as you read this.

Every Adjacent Attraction: More Ways They Fail Saginaw Families

Trampoline parks in City of Saginaw have evolved into “adventure parks” or “family entertainment centers.” They aren’t just trampolines anymore. They are bolting on high-risk mechanical attractions that their staff is not trained to supervise.

Sky Rider and Zipline Strangulations

The Sky Rider zipline-coaster at Urban Air has a documented chain-wide pattern of strangulation and falls. From Newnan, Georgia to North Texas, children have been caught in these harnesses because the design is fundamentally flawed. We subpoenas the chain-wide incident history to prove they knew the attraction was dangerous and kept it open anyway.

Climbing Walls and Harness Failures

The Matthew Lu fatality in North Carolina is the warning every Saginaw parent needs to hear. A 12-year-old fell 20 feet onto concrete because the harness wasn’t secured. The park admitted “human error” and removed the attraction. In Sugar Land, Texas, the Lakhani family is currently suing after their daughter fell 30 feet from a climbing wall because the attendant never attached the fall protection. If your child fell from height at a park, the park’s “auto-belay” or “harness” defense is something we know how to pierce.

Urban Air Go-Karts

The 2025 fatality of six-year-old Emma Riddle in Port St. Lucie, Florida, happened because an electric go-kart surged forward without driver input. When these “adventure” attractions fail, they produce high-velocity trauma. These karts are governed by the Texas Amusement Ride Safety Inspection and Insurance Act, and we know how to pull the TDI inspection records to show the park missed its compliance stickers.

Why City of Saginaw Families Trust Attorney911

Most personal injury firms in North Texas handle trampoline cases like any other slip-and-fall. They don’t know ASTM F2970. They don’t know the difference between a Salter-Harris II and a buckle fracture. They certainly don’t have an attorney who used to defend these parks.

We are different. We have spent over two decades litigating against multi-national corporations. Ralph Manginello’s federal court experience and our firm’s track record against companies like BP and Amazon mean we aren’t intimidated by the private equity firms that own Sky Zone and Urban Air.

As our client Chad Harris said, “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.” That is our commitment to City of Saginaw families. We know that behind every case is a kid who just wanted to have a good Saturday and a parent who is now worried about how they will pay for 40 years of medical care.

We advancement every expense—the biomechanical engineer who reconstructs the energy transfer of the double-bounce, the computer forensic expert who recovers the deleted video, and the life-care planner who builds the 70-year medical forecast your child’s injury demands. You pay nothing until we pick up a check for you.

Frequently Asked Questions for City of Saginaw Parents

What should I do if my child got hurt at a Sky Zone or Urban Air in City of Saginaw?

First, get specialized medical care. Do not rely on an urgent care center for a potential head or spine injury; go to a Level 1 pediatric trauma center like Cook Children’s in Fort Worth or Children’s Medical Center in Dallas. Second, do not sign any “incident follow-up” or “medical payment” forms the park offers—these are often releases in disguise. Third, call us at 1-888-ATTY-911 immediately. We need to send a spoliation letter within 24–72 hours to ensure the park does not overwrite the surveillance video.

Can I sue Urban Air if I signed a waiver in Texas?

Yes. Texas law prohibits waivers from releasing claims of gross negligence or recklessness. Furthermore, the case of Munoz v. II Jaz established that a parent generally cannot pre-emptively waive a minor child’s independent legal rights. Many Urban Air waivers also contain delegation clauses and arbitration agreements, but after the 2025 Cerna v. Pearland Urban Air decision, we have developed specific strategies to attack these clauses and keep your case in a courtroom whenever possible.

How much can my family get for a trampoline injury settlement in City of Saginaw?

Settlement values depend on the severity of the injury and the insurance layers we can access. A typical pediatric femur fracture with growth plate involvement often anchors in the $500,000 to $2 million range. Catastrophic spinal cord injuries or TBIs can result in eight-figure settlements or verdicts, such as the $11.485 million Cosmic Jump verdict in Harris County or the $15.6 million Damion Collins award. Our goal is always the maximum recovery for your child’s lifetime needs.

How long do I have to sue a trampoline park in Texas?

In Texas, the statute of limitations for personal injury is generally two years. However, for a minor, that clock is “tolled” (paused) until they turn 18, meaning they have until their 20th birthday to file. Do not wait this long. The evidence you need to win—the video, the witness statements from other parents, and the maintenance logs—is often destroyed within weeks of the accident. The legal deadline is not your biggest concern; the evidence deadline is.

Who is responsible when a City of Saginaw trampoline park monitor isn’t watching?

We look at the entire corporate stack. The local operator LLC is responsible for their employees’ actions under respondeat superior. However, we also pursue the franchisee and the franchisor (like Sky Zone Franchising LLC or Urban Air Franchise Holdings). If the parent company’s private equity sponsor approved cost-cutting measures that led to understaffing, we can pursue those deep pockets as well. We find the money wherever it is hidden.

Why is the trampoline park insurance company offering us money so fast?

This is the “Quick Med-Pay” tactic. The adjuster may offer a few thousand dollars to cover your initial ER copay. They hope you will sign a “simple release” on the back of the check that ends your ability to sue for the hundreds of thousands of dollars in future surgeries or lost earning capacity your child will actually face. Never accept a quick check without having a lawyer review the paperwork.

Is the “Glow Night” at trampoline parks more dangerous?

Yes. Many lawsuits have successfully argued that reduced lighting during “Glow” or “Cosmic” events makes effective supervision impossible. Lex meters often show that ambient light levels are below what is required for a court monitor to see a small child in a corner. These events often have the same staffing levels as daytime hours despite the increased risk, which supports a claim for gross negligence.

Can I sue if the waiver was only in English and we speak Spanish?

Yes. Under the Delfingen doctrine in Texas, if a contract is presented to a non-English speaker in English without a translation or full explanation, it can be voided for procedural unconscionability. Our attorney Lupe Peña speaks Spanish natively and deals with these situations directly. Si firmó el documento en inglés y su idioma principal es español, nosotros podemos ayudarle.

What is a “trampoline fracture”?

It is a specific medical term for a fracture of the proximal tibial metaphysis, typically seen in children under the age of six when they jump with a heavier person. Because a toddler’s bones are not fully ossified, they cannot handle the rebound force sent through the mat by an adult. The American Academy of Pediatrics says children under six should never be on a trampoline for this reason. If a City of Saginaw park let your toddler jump with older kids, they violated a massive safety standard.

What happens if the park’s surveillance video is missing?

This is a major part of our investigation. When video goes “missing” after we have sent a preservation demand, we ask the court for an “adverse inference” instruction. This tells the jury they are allowed to assume the missing video would have shown the park was negligent. In many cases, proving the park destroyed evidence is even more powerful than the video itself, as it proves they were conscious of their own fault.

How do I know if my child has rhabdomyolysis after jumping?

Look for “cola-colored” or dark brown urine, severe muscle pain that makes them cry or unable to walk, and extreme fatigue. This usually happens 12 to 48 hours after the visit. In City of Saginaw’s summer heat, this is a major risk. Go to the ER immediately and demand a CK (creatine kinase) test. Then call us—we have a $10 million architecture ready for rhabdo cases.

Does it cost any money to hire Attorney911?

No. We work on a 100% contingency fee basis. We advance all the expensive costs of litigation—the private investigators, the medical experts, and the engineers. If we don’t recover money for your family, you owe us nothing. Your child’s recovery fund stays untouched while we fight the corporate lawyers.

Why should I choose a “nationwide” firm for a Saginaw case?

Because the parent companies and insurers for Sky Zone and Urban Air are national entities with national playbooks. A local “generalist” lawyer who handles car wrecks might not know the chain-wide strangulation patterns of the Sky Rider or have the ASTM standard memorized. We bring national authority and 25+ years of catastrophic injury experience to your City of Saginaw neighborhood.

Is my homeowner’s insurance going to cover my neighbor’s kid?

Most Texas homeowners’ policies have a specific “trampoline exclusion.” If a neighbor’s child is hurt in your backyard, you might be uninsurable for that claim. We look at the manufacturer for product defects and your umbrella policy to find coverage where the primary house policy fails.

What should I have done differently?

Stop blaming yourself. You are not a safety engineer; you are a parent who took your kid out for a fun afternoon. The park accepted the duty to be safe the moment they took your credit card. They failed that duty. Our job is to make sure they are held accountable so it doesn’t happen to the next City of Saginaw family.

Your Case Is Decided by What You Preserve This Week

What happened to your child at a City of Saginaw trampoline park was not an act of God—it was the predictable result of an industry that treats high-risk athletics like a playground and profit like a priority. From the American Academy of Pediatrics to the International Organization for Standardization (EN ISO 23659:2022), the warnings have existed for decades. The park had the rules; they just didn’t follow them.

Attorney911 was built for exactly this fight. Managing Partner Ralph Manginello brings 25+ years of trial experience and the toughness that comes from litigating against companies like BP and Walmart. Lupe Peña knows the insurance defense script because he used to live it. We know which Texas courts will void the waiver and which experts will convince a Tarrant County jury that a growth plate injury is a lifetime of damages.

The evidence in your case is evaporating right now. Surveillance DVRs in parks near I-35W are already counting down to the moment they overwrite the record of your child’s injury. The staff who ignored the rules are ready to move on to different jobs.

You signed the document because you trusted them. Now, trust us to hold them accountable. We advance every expense—biomechanists, pediatric surgeons, and life-care planners. Your child’s recovery fund stays yours. We only get paid when we win.
