Grassi
Services:
Grassi is an independent advisory, tax, and accounting firm dedicated to serving middle-market businesses, nonprofits, public companies, families, and high-net-worth individuals with deep industry expertise and a high-touch approach. Founded in 1980 by Louis C. Grassi, our firm began with an empty filing cabinet, a desk, and a founding belief that client service belongs at the center of business.
For more than four decades, those values have guided our growth into one of the nation’s largest accounting firms and continue to shape our customized, relationship-driven approach. Our long-standing client relationships reflect this commitment, consistently earning satisfaction scores more than twice the industry average. From complex transactions and audits to operational strategy, succession planning, and long-term wealth preservation, we provide guidance and tools to help leaders reduce tax liabilities, address challenges, and build a sustainable future.
