It’s this breadth of experience that James brings to his firm and, more importantly, to his clients.
As a Deputy District Attorney, James first-chaired numerous criminal trials, tackling charges that spanned the spectrum of criminal law and shaped his approach to litigation.

Pirapat “Peter” Sindhuphak
With nearly two decades in high-stakes insurance and employment litigation, Peter brings the uncommon perspective of a former senior in-house lawyer at one of the nation’s largest insurers to the firm’s plaintiff-side practice. He now channels that inside knowledge to stand up for policyholders and employees who have been wronged by insurance companies and employers.
As an in-house lawyer, Peter managed litigation strategy in single-plaintiff cases and class actions across the country, managed and conducted sensitive internal investigations, and successfully resolved federal and state administrative charges. He also provided legal advice on issues regarding reductions in force, ADA accommodations, wage and hour compliance, pay equity, AI use, and discrimination/harassment/retaliation risks. He knows exactly how insurers and corporate defendants evaluate risk and how to leverage that knowledge for individuals.
Earlier in his career, Peter was a senior associate at a leading California insurance law firm, where he defended insurers in complex coverage, bad-faith and class action lawsuits in federal and state courts. The experience taught him exactly where carriers look for weaknesses—and how to turn that knowledge into leverage for the people he now represents.
Peter’s experience also includes first-chair jury and bench-trial experience dating back to his tenure as a Deputy District Attorney. His appellate experience dates back to law school where he served as a law clerk for Associate Justice Werdegar at the California Supreme Court and Associate Justice Earl Johnson at the California Court of Appeal, Second Appellate District. In private practice, he worked on precedent-setting appeals that resulted in favorable results for clients.
Whether the dispute involves wrongful denial of benefits, bad-faith claims handling, wage-and-hour violations, discrimination, or retaliation, Peter’s blend of insurance-coverage depth and employment-law fluency equips him to attack complex issues from every angle.
