With over 550 employees, Grassi & Co., CPAs, P.C. is a large accounting firm that works with organizations that need clear financial reporting and reliable oversight.
Founded in 1980, the firm provides audit services alongside related accounting support. Retirement plan sponsors often look for 401(k) auditors who can coordinate closely with internal finance teams and third-party administrators, and Grassi & Co. offers that mix of plan-focused audit work and broader firm resources.
Beyond audit engagements, the firm has professionals who cover day-to-day finance leadership and specialized reviews. That includes CPA services, CFO support, business consulting, forensic accounting, and tax advisory work.
What sets the firm apart is the range of in-house specialties available under one roof, which can reduce handoffs when a plan audit touches payroll, tax reporting, or internal controls.
