Gray, Gray & Gray

What Gray, Gray & Gray does

Gray, Gray & Gray is a CPA and business advisory firm founded in 1945 and headquartered in Canton, Massachusetts. The firm provides professional services across four core lines: consulting and advisory, audit and assurance, tax services, and affiliated offerings in private wealth and investment banking. It serves middle-market clients across nine specialized vertical industries: architecture/engineering/design, construction, energy, life sciences, manufacturing/distribution, non-profit, real estate, SaaS, and technology. The firm is organized as a private limited liability partnership with approximately 200 employees and a partner group of roughly 14.

The firm's revenue model is anchored in recurring professional services fees. Audit, tax compliance, and ongoing advisory engagements produce long-duration client relationships, with engagements typically billed on hourly, fixed-fee, or retainer structures. Cross-sell across audit, tax, and advisory strengthens per-client revenue, while affiliates in private wealth and investment banking extend monetization beyond core CPA services. Membership in CPAmerica Inc. provides access to peer-firm resources, technical training, and international affiliation, expanding service delivery without proportional headcount growth.

The firm's technology stack is built on standard professional services tooling: Sage Intacct for cloud ERP, SafeSend for tax return delivery, and Google Analytics for web presence. In 2026, the firm formalized a dedicated Sage Intacct & Advisory Practice under Managing Principal Todd Donatello, signaling a deliberate move into cloud-ERP migration and optimization services. Recognition includes placement on the Boston Business Journal Fast 50 for two consecutive years, the Financial Times Fastest Growing Americas list, Inside Public Accounting Top 200, a #20 ranking in Massachusetts, and the Best of the Best 2025 award, all of which point to a firm scaling above industry averages while maintaining a focused regional footprint.
