Thiago M. Coelho Esq. - Los Angeles, CA

Thiago M. Coelho, Esq. is a Partner at Wilshire Law Firm, PLC, and serves as the Chair of the Consumer and Data Privacy Class Action departments. He represents large classes of consumers in complex, large-scale litigation in state and federal trial and appellate courts across the United States. Among the few attorneys in California with class action trial experience through verdict, Thiago brings rare courtroom experience to high-stakes class action litigation. A Los Angeles County Superior Court Complex Civil judge described his trial advocacy as “excellent” and “extraordinary,” while another judge recognized his “extensive experience litigating consumer class actions.” His litigation experience has earned him significant recognition, including a 2024 California Lawyer Attorneys of the Year (CLAY) award from The Daily Journal.

Thiago has litigated hundreds of cases nationwide and has extensive experience across all stages of litigation, including trials and appeals. His victories include notable appellate decisions in state and federal courts across multiple jurisdictions. In California, he helped secure the landmark published decision in Moore v. Centrelake Medical Group, Inc., 83 Cal. App. 5th 515 (2022), a medical data breach decision cited more than 320 times, in which the California Court of Appeal reversed dismissal of key UCL and contract claims. In Georgia, he prevailed in Bland v. Urology of Greater Atlanta, LLC, 377 Ga. App. 177 (2025), where the Georgia Court of Appeals reversed dismissal of negligence, implied-contract, implied-covenant, and injunctive-relief claims in a healthcare data breach class action. At the federal appellate level, Thiago’s record includes Ninth Circuit victories such as Freeman, et al. v. 3Commas Technologies OÜ, No. 24-6158 (9th Cir. Mar. 2, 2026), where the court reversed the district court’s personal jurisdiction dismissal of a data security class action involving an AI-enabled cryptocurrency trading platform, and Mier v. CVS Health, No. 22-55665, 2023 WL 4837851 (9th Cir. July 28, 2023), where he obtained Rule 23(f) review, resulting in partial vacatur and remand of the denial of class certification.

Beyond his appellate victories, Thiago has secured substantial class-action recoveries for consumers. In Peters, et al. v. Apple Inc., No. 19STCV21787 (Cal. Super. Ct.), he recovered 90% of the maximum value through a $25 million common-fund settlement. Thiago also helped secure a $49,995,000 settlement in Head, et al. v. Regal Medical Group, Inc., et al., No. 23STCV02939 (Cal. Super. Ct.), a healthcare data-breach class action. In In re MOVEit Customer Data Security Breach Litigation, MDL No. 3083, Thiago is one of two attorneys appointed by the court on the Experts Committee in a nationwide data-breach MDL involving hundreds of cases and more than 90 defendants; the litigation has generated more than $30 million in settlements to date. In 2024, he also secured what was then the second-highest known class-action settlement of its kind against a fashion retailer.

He has been recognized by industry peers for his dedication to excellence and has received numerous legal accolades, including Best Lawyers in America: Ones to Watch, Super Lawyers, Top 40 Under 40, Top 25 Class Action Attorney, and the Top 10 Data Privacy Attorney.
