Tom Loeser is Managing Counsel in the firm and licensed in California, Washington and the District of Columbia. Tom works primarily in the Seattle office but also from the Burlingame office, where he represents consumers in technology-related class action and other complex cases. Tom is a Martindale-Hubbel AV Preeminent Rated Superlawyer and member of Law Dragon’s 500 Leading Plaintiffs Consumer Lawyers and 500 Leading Plaintiffs Financial Lawyers. Mr. Loeser adds a hard science, and a high-technology career to his 26 years of litigation, including 19 years in class actions and five years as a federal cyber-prosecutor. Mr. Loeser’s technology career included an MBA, writing code for the Treasury at Microsoft, a financial analyst position at the Hewlett-Packard Company and technology licensing in Silicon Valley.
In 2002, Mr. Loeser was appointed an Assistant United States Attorney in Los Angeles where after two years of prosecuting all manner of federal crimes, he joined the elite Cyber and Intellectual Property Crimes Section. This role required years of training in the investigation and prosecution of hacking, computer intrusion, cyber-stalking, online child-predation, malware, cyber-extortion and data breach cases. The training was cutting edge, requiring Top Secret clearances, and it was ongoing throughout Mr. Loeser’s government service. Mr. Loeser resolved hundreds of criminal cases—including federal hacking, child predation and data theft cases—and brought over a dozen federal cases to trial and through appeal.
Mr. Loeser’s practice has included the prosecution and resolution of dozens of complex actions against the titans of industry, including social media, gaming, online messaging, national banks, insurers, builders, title companies, carmakers, mortgage lenders, trucking companies and nationwide retailers. Mr. Loeser specializes in the prosecution of cases that are not just complex because of the legal and procedural issues involved, but also because of the technological sophistication of the products, services or bad acts underlying the legal claims.
Mr. Loeser has worked extensively on many of the largest consumer class cases in U.S. history. These include legion auto defect cases such as the $10 billion Volkswagen “Clean Diesel” MDL and the related $1.3 billion Volkswagen Franchise Dealer litigation. Mr. Loeser has worked on dozens of privacy and data theft cases including the antitrust case against Meta for its abusive collection of consumer data, and leadership roles in the massive 2022 T-Mobile data breach case, the AT&T Data breach affecting 75 million past and present customers, the GM OnStar vehicle tracking litigation and cases against PayPal, Rakuten and RetailMeNot for theft of commissions due online influencers. Mr, Loeser’s role in these cases touches on all aspects of litigation, including leadership, strategy, discovery, depositions, legal briefing and settlement.
Mr. Loeser’s work has garnered praise from the plaintiffs class action bar, who regularly ask him to speak at class action conferences, and from judges, including Judge Beth Labson Freeman in San Jose who remarked on the record:
“It’s not simple, you make it look easy, and that's the art of what you do, Mr. Loeser, and the Court certainly appreciates the good work in this case, and in recognition of the many cases that your firm has handled over the years.”
Dean Sheikh et al v. Tesla, Inc. Final Approval of Settlement Hearing, The Honorable Beth Labson Freeman, United States District Judge for the Northern District of California San Jose Division.
Outside of work Tom enjoys time with his family cycling, skiing, snowboarding, surf-foiling, and in all manner of ocean activities.
