Fortune 500 corporations. National healthcare conglomerates. Companies with armies of lawyers. We fight them anyway — and we win.
Jack Siegel grew up in a working-class family on the north side of San Antonio. When he was 13, his dad lost his job, and his mom Susan went to work at a CVS call center — where she stayed for 18 years before being pushed out. That experience left a mark. It's the reason Jack became a lawyer, and it's the reason he only fights for one side.
He graduated summa cum laude from the University of Texas at Austin with a 4.0 GPA, then earned his law degree from USC's Gould School of Law — a top-20 program. But what really shaped him as a trial lawyer happened next. Jack served as lead associate for Tony Buzbee, the Houston attorney behind more than $10 billion in recoveries, including the landmark Deepwater Horizon litigation. He also worked closely with Rogge Dunn, a board-certified employment litigator with more than $2 billion in career results and over 20 years on the Super Lawyers list. Under those two, Jack learned how to fight — and how to win.
Before that, Jack had already gone up against corporate America. He teamed up with his high school friend Hao Ni — a patent attorney who finished engineering and law degrees at the University of Texas by age 21, now at Ni, Wang & Massand — to bring patent false marking suits against more than 18 Fortune 500 companies. It was an unconventional start. But it taught him something he carries into every case: you don't need a big firm behind you to take on the biggest companies in the country. You just need to know the law better than they do.
"People assume I'm the overachiever in this friendship because I finished two degrees by 21. But you can't teach hunger, and Jack had more of it than anyone I've met. Two middle-class kids from the north side of San Antonio weren't supposed to be suing Fortune 500 companies. Jack didn't get the memo. That he became one of the most prolific wage-and-hour lawyers in the country was the least surprising thing about him." — Hao Ni, Patent Attorney, Ni, Wang & Massand
In 2014, Jack opened Siegel Law Group with one purpose: fighting for workers whose employers steal their wages. He doesn't represent corporations. He doesn't hedge. He picks a side — the worker's side — and fights.
"I just don't go into cases thinking I'm going to lose. The way I see law is, it's a fight." — Jack Siegel, Super Lawyers, "More at Stake"
How a solo practitioner from San Antonio built a national overtime practice that Fortune 500 companies and Am Law 100 firms can't ignore.
Since then, Jack has filed more than 100 federal overtime lawsuits across 27 federal courts in 20+ states, recovered more than $100 million for workers*, and earned 50+ class and collective certifications nationwide — more than most employment firms achieve in a generation. He concentrates on FLSA collective actions and state-law class actions, often brought together as hybrid suits that maximize pressure on employers who misclassify workers and pocket the difference.
The cases he takes aren't small. Jack regularly goes up against Fortune 500 companies and national healthcare conglomerates — and the results speak for themselves. When he took on CVS Health, it was personal: his mother was one of the workers who had been shortchanged. That case resulted in a $15.25 million settlement for over 15,000 call center workers — recognized as a Top 10 Wage & Hour Settlement in the United States by both TopVerdict.com and the Seyfarth Shaw Annual Workplace Class Action Litigation Report. He followed it up by taking on Unum Group — the third-largest group disability carrier in the country — and securing a $14.8 million settlement for 947 workers who had been denied overtime.
Jack works alongside Josh Kroot of Primary Law Group — a close friend since they were classmates at USC Law in 2009. Josh, a former attorney at a major New York firm, now focuses full-time on worker-side wage and hour cases. Together, they represent case management and utilization review employees in overtime cases across the country — with more than $100 million in recoveries, 50+ certifications, and cases against Fortune 500 defendants.
"I've known Jack since our first week at USC Law, and even then he thought about the law differently than everyone else in the room. When I was still at a big New York firm, Jack called me and said he'd figured out that managed care companies were systematically misclassifying workers — and that nobody was doing anything about it. He was already the leading voice in the space by the time I joined him. Most lawyers find a niche. Jack built one." — Josh Kroot, Primary Law Group
He is a contributing author to two of the leading wage and hour treatises in the country: Bloomberg BNA's The Fair Labor Standards Act (Kearns) and Bloomberg BNA's Wage and Hour Laws: A State-by-State Survey. He has been named a Texas Super Lawyers Rising Star three years running (2021, 2022, 2023) and is a member of the ABA Labor & Employment Law Section.
Not every case that comes through the door gets taken. Jack is selective — he only takes cases he believes in. That's not a slogan; it's the reason the firm can go up against Fortune 500 companies and win. When Siegel Law Group takes your case, it's because they've looked at the facts, studied the law, and decided it's a fight worth having. Otherwise, they'd just be running a volume practice — and that's not what this firm is.
He doesn't do this work because it's easy. He does it because he watched his mom get treated like she didn't matter — and he decided a long time ago that no one should have to accept that.
*Includes amounts recovered in connection with the pending Presbyterian Healthcare Services settlement ($38.7M), which received preliminary approval on March 3, 2026 and is subject to final court approval. Prior results do not guarantee a similar outcome.
Presbyterian is New Mexico's largest private employer. The Siegel Law Group took on the hospital system on behalf of managed care workers misclassified as exempt from overtime. Presbyterian started with Ogletree Deakins, then upgraded to Wheeler Trigg O'Donnell — a firm Chambers USA calls "a dominant litigation boutique." The case settled for $38.7 million, the largest managed care overtime recovery of its kind.
Pruess v. Presbyterian Health Plan, Inc. (D.N.M.) — Prelim. approved 3/3/2026Jack's mother worked at a CVS call center for 18 years. After she was let go, Jack discovered that CVS wasn't paying customer service reps for required pre- and post-shift work at call centers nationwide. He brought in representatives from all 15 CVS call centers, fought off arbitration motions, uncovered destroyed records, and secured a $15.25 million settlement for over 15,000 workers.
Woods v. Caremark PHC, LLC (W.D. Mo.)Unum Group, a Fortune 500 insurer, retained Paul Hastings — an Am Law 20 firm with more than a thousand attorneys worldwide — to defend overtime claims brought by its own employees. The Siegel Law Group recovered $14.8 million for the workers.
Deakin v. Unum GroupCentene is one of the largest managed care companies in the country. Jack conditionally certified a class of over 2,000 managed care employees who were denied overtime pay despite working well beyond 40 hours per week.
Del Toro v. Centene Mgt. Company, LLC (E.D. Mo.)UnitedHealth Group — the third-largest company on the Fortune 500 — was defended by Littler Mendelson, the nation's largest employment law firm. The Siegel Law Group won two consecutive appeals before the Tenth Circuit.
Fedor v. United Healthcare (10th Cir.)HCSC is the largest customer-owned health insurer in the United States. Jack has brought multiple actions against the company on behalf of misclassified employees, securing class certification and settlements for workers across multiple states.
Candelaria v. Healthcare Service Corp. (D.N.M.)The companies on the other side of our cases have the resources to hire any law firm in the country. And they do.
When Unum Group, a Fortune 500 insurer, faced overtime claims from its own employees, it retained Paul Hastings — an Am Law 20 firm with more than a thousand attorneys worldwide. That case resulted in a $14.8 million recovery for the workers.
When Presbyterian Healthcare Services, New Mexico's largest private employer, needed to defend the Pruess class action, it started with Ogletree Deakins — one of the three largest employment firms in the country, with nearly a thousand attorneys. After losing ground, Presbyterian upgraded to Wheeler Trigg O'Donnell, a Denver trial boutique that Chambers USA calls “a dominant litigation boutique celebrated for its talent in civil trials.” BTI Consulting named WTO among the 14 “Most-Feared” firms in the country. The firm's attorneys had taken more than 1,100 trials and arbitrations to verdict. The case settled for $38.7 million — the largest managed care overtime recovery of its kind.
When CVS/Caremark — Fortune 500 number five — needed to fight a class action brought on behalf of more than 15,000 workers, it retained Seyfarth Shaw, the Am Law 50 firm that publishes the industry's definitive annual ranking of workplace class action settlements, alongside Polsinelli, an Am Law 100 firm. The Siegel Law Group recovered $15.25 million.
When Magellan Health wanted to fight back against a single plaintiff, it didn't hire one firm — it hired four simultaneously, including Baker McKenzie, the single largest law firm on the planet by headcount, Littler Mendelson, the nation's largest employment defense firm, and Jackson Lewis.
When UnitedHealth Group — the third-largest company on the Fortune 500 — took its case to the Tenth Circuit, it was defended by Littler Mendelson, the nation's largest employment firm with over 1,700 attorneys. The Siegel Law Group won. Twice.
Other cases have drawn Morgan, Lewis & Bockius (Am Law 10, 2,200+ attorneys), Greenberg Traurig (Am Law 15, 2,700+ attorneys), McGuireWoods, Perkins Coie, Davis Wright Tremaine, and Duane Morris — which publishes its own annual class action report.
The firms that literally write the book on class action litigation have faced off against us — and we're still here.
