Grassi Information

Founded in 1980 with just a desk and an empty filing cabinet, Grassi has grown into one of the nation's leading independent advisory and accounting firms. With client satisfaction more than twice the industry average, we're proud to be ranked 16th on Vault's Best US Accounting Firms to Work For. We have earned this reputation through exceptional client service and by staying true to our core values. As strategic advisors, Grassi professionals are dedicated ambassadors of our client's future business aspirations. Everything we do centers on our client's success and the enrichment of our relationships with them. While other firms merge or take private equity funding, Grassi secured its independence by transitioning to an employee-owned ESOP in 2023. This independence empowers us to focus on what matters: exceptional service and strategic guidance to help our clients’ businesses thrive.
