We have never once been on their side.
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. 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 — to bring patent false marking suits against more than 18 major 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 a national corporation. You just need to know the law better than they do.
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.
In March 2022, Super Lawyers reported that Jack was litigating against Presbyterian and UnitedHealth in New Mexico. Both cases have since resolved.
"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 major companies and Am Law 100 firms can't ignore.
Since then, Jack has filed more than 100 federal overtime lawsuits in 25 federal districts across 20 states and earned 50+ class and collective certifications. He concentrates in 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 major corporations and national healthcare companies — 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. As lead counsel, he secured a $16,669,155.84 settlement for 12,034 call center workers (Doc. 273). The fund grew from $15.25 million at preliminary approval to $16,669,155.84 after additional class members were identified. Overtime claims against Unum Group resulted in a $14.8 million settlement for 947 workers who had been denied overtime.
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 put everything it has into the cases it takes. 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.
USC Gould School of Law, 2009. Former law clerk to the Honorable Fred Biery, U.S. District Court for the Western District of Texas.
The case that started it all was personal: Jack took on CVS Caremark over unpaid call-center time for workers including his own mom, who'd given the company 18 years. In May 2019 a federal judge appointed him class counsel for more than 15,000 call center workers. It was the first time a court put him in charge of a class. His mom was one of them. Read the story.
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.
Prior results do not guarantee a similar outcome.
Jack took on Presbyterian as lead counsel for 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.
Pruess v. Presbyterian Health Plan, Inc. (D.N.M.) — Final approval granted 6/24/2026Jack'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. As lead counsel, he brought in representatives from all 15 CVS call centers, fought off arbitration motions, litigated through a contested discovery record, and secured a $16,669,155.84 settlement for 12,034 workers (Doc. 273).
Woods v. Caremark PHC, LLC (W.D. Mo.)Unum Group 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 case resulted in a $14.8 million recovery for the workers.
Loomis v. Unum Group (E.D. Tenn.)As lead counsel, Jack settled the claims of 1,228 salaried employees on a class-wide basis.
Del Toro v. Centene Mgt. Company, LLC (E.D. Mo.)UnitedHealth Group was defended by Littler Mendelson. As lead counsel, Jack won two consecutive appeals before the Tenth Circuit.
Fedor v. United Healthcare (10th Cir.)We represented the workers in multiple actions against HCSC 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 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 needed to defend the Pruess class action, it started with Ogletree Deakins — a national employment firm 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.
When CVS/Caremark 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 an annual workplace class action report, alongside Polsinelli, an Am Law 100 firm. Jack Siegel, as lead counsel, recovered $16,669,155.84 for the class.
When UnitedHealth Group took its case to the Tenth Circuit, it was defended by Littler Mendelson, an 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.
