The Walnut Creek office, which initially opened in Oakland in April 2014 with attorneys from the firm's Environmental & Toxic Tort Practice Group, alongside administrative and financial staff members, relocated to Walnut Creek in April 2024.

Alongside GRSM's downtown San Francisco headquarters, the Walnut Creek office strengthens the firm’s ability to offer premium client service on both sides of the Bay while simultaneously optimizing operational costs. The Walnut Creek office not only extends the firm's reach in the East Bay but also facilitates collaboration between our Bay Area and Central Valley teams. 

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, Maritime, Intellectual Property, and Business Transactions.
