Current company Grassi
Professional Services · 624 employees · Founded 1980 · Jericho, New York, United States
Founded in 1980 with just a desk and an empty filing cabinet, Grassi has grown intoa leading independent, employee-owned advisory, tax, and accounting firm serving middle-market businesses, public companies, high-net-worth individuals, and nonprofit organizations. Ranked the 52nd-largest accounting firm in the United States, Grassi provides specialized services across key sectors, including construction, manufacturing and distribution, financial services, healthcare, nonprofit, real estate, architecture and engineering, and more. With 10 offices across the U.S. and global reach through PrimeGlobal, Grassi collaborates with clients to drive growth, manage complexity, and build lasting success.
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.
