Grassi Named a 2025 “Best of the Best” Accounting Firm for 15th Year
New York, NY — Grassi, a leading provider of advisory, tax and accounting services, has once again been named to INSIDE Public Accounting’s prestigious “Best of the Best” list, marking the 15th time the firm has received this honor. Selected from more than 600 participating firms, Grassi was recognized for its performance across key benchmarks, including revenue growth, governance, professional development, compensation and long-range planning.
Earlier this year, IPA ranked Grassi #52 on its Top 500 list, recognizing the firm’s consistent growth and client-centric approach. Reporting double-digit year-over-year revenue growth, Grassi attributes its strong performance to a client-first philosophy that has driven satisfaction rates more than twice the industry average and earned five consecutive Best of Accounting Diamond Awards for client service excellence.
“Being named to the ‘Best of the Best’ list for the 15th time highlights our continued focus on our clients’ needs and our independence as a firm,” said Louis C. Grassi, CEO, Founder and Managing Partner of Grassi. “We are grateful for this recognition and will continue to place our clients at the center of all we do, upholding the high standards of excellence that drive our growth.”
As the second-largest Employee Stock Ownership Plan (ESOP) accounting firm in the nation, Grassi emphasizes a culture of accountability, collaboration and shared ownership. This culture has been recognized with multiple workplace honors in 2025, including being named to Vault’s Accounting 25 list, a national ranking of the best accounting firms to work for, as well as receiving many regional “Best Places to Work” awards across the Northeast.
With a growing team of more than 550 professionals across ten offices, Grassi remains committed to creating success for its clients and its people while expanding its reach and impact.
