GRSM was founded in San Francisco in 1974, and the firm's first office has rapidly grown to more than 120 lawyers. What began as a small general practice law firm has quickly become among the 10 largest in San Francisco and the 25 largest in the nation. Today, the firm's two Northern California offices are recognized as having premier practices in Insurance, Construction, Employment, Health Care, Drug & Medical Device, Environmental/ Toxic Tort, Commercial Litigation, Tort & Product Liability, Intellectual Property, and Business Transactions.
Many of the firm's San Francisco lawyers serve in leadership positions in legal organizations and client industry associations, including the Defense Research Institute, Professional Liability Underwriting Association, Federation of Defense & Corporate Counsel, International Association of Defense Counsel, Building Owners and Managers Association, Excess/Surplus Lines Claims Association, National Foundation for Judicial Excellence, San Francisco Women Lawyers Alliance, California Women Lawyers, and Food & Drug Law Institute.  
Over and above the practice of law, the San Francisco office is deeply committed to giving back to the community, and we are proud to have been named the Bay Area's "Most Philanthropic Law Firm" by United Way.  In addition, many of our lawyers are members of the Boards of organizations such as "First Graduate" and "Under One Roof."
