Attorney Information
Overview
Bill Keith represents clients in the areas of business litigation, class actions, and legal malpractice. He has successfully tried multiple cases to verdict, both as lead counsel and as a member of trial teams. Bill has an excellent record on appeals before the Ninth Circuit and the California Court of Appeal.
Bill was selected to the Southern California Super Lawyers® list in 2024 and 2025, and was previously selected as a Super Lawyers® Rising Star seven years in a row. Bill is rated “AV Preeminent” by Martindale-Hubbell.
Bill believes in a proactive approach to litigation and trial preparation, which starts with a thorough and early assessment of a client’s claims and defenses, the case’s potential outcomes, and litigation themes. He knows clients are only able to make informed business decisions about how to manage and settle disputes—or when to go to trial—when they have a clear idea of the landscape and risks that lie ahead.
Bill’s business litigation practice encompasses disputes involving misappropriation of trade secrets, unfair competition, breaches of fiduciary duty, partnership disputes, securities, and insurance coverage. Bill has significant experience representing clients in the financial services industry in a variety of contexts.
In his class action practice, Bill defends manufacturers, food producers, and other clients in claims brought under consumer protection laws (California’s Unfair Competition Law, False Advertising Law, and Consumer Legal Remedies Act, and New York’s General Business Law) and other statutes and theories. He has experience with actions involving “Made in America” claims and claims that products violate regulations issued by the FTC, USDA, and other agencies.
Bill graduated from the University of North Carolina at Chapel Hill with a degree in Business Administration. He earned his law degree from Florida State University College of Law, where he graduated cum laude and Order of the Coif. Bill is admitted to practice law in California and Florida.
Bill’s volunteer work includes acting as pro bono counsel in connection with San Diego’s Casa Cornelia Law Center. He successfully represented a journalist seeking asylum in the United States after the client was forced to flee his Central American country on account of state-sponsored persecution.
