Supporting the missions behind the numbers.
RAE & Associates is a Greater Boston advisory and assurance firm built around a simple idea: the real value of accounting is not producing numbers — it is helping leaders understand what those numbers mean, and what to do next.

The RAE Advantage
Big firm experience.
Personal firm attention.
Our Managing Partner spent years inside Deloitte and held an Audit Partner seat at a Top-100 national firm before founding RAE & Associates. Our clients gain access to the same caliber of judgment, methodology and technical depth — without becoming just another account number.
01
Deloitte heritage
Methodology, training and standards refined inside one of the world's largest professional services firms.
02
Audit Partner experience
Former Audit Partner leadership at Prager Metis, a national Top-100 accounting and advisory practice.
03
Regional firm leadership
Two decades guiding commercial, nonprofit, real estate and professional service organizations.
04
Boutique responsiveness
Direct partner access on every engagement. The expertise of an institution. The attention of a practice.
Our Philosophy
More than numbers.
Today's organizations need more than financial statements, tax filings and compliance reports. They need clarity. They need interpretation. They need someone who can read the story behind the numbers — and tell them what to do about it.
Clarity
Translating financial complexity into language leadership can act on.
Interpretation
Surfacing what the numbers actually reveal about performance, risk and trajectory.
Guidance
Recommending the next decision — not just documenting the last one.
“The real value of an accounting firm is not in producing numbers. It is in helping clients understand what those numbers mean — and make better decisions because of it.”

Who We Serve
Built for organizations that need more than tax preparation.
Our clients share one thing in common: when the financial decision matters, they want someone in the room who has seen it before — and is ready to act.
Small Businesses
Owner-operators who need a financial partner who actually returns the call.
Growing Companies
Organizations entering the stage where decisions are larger, faster and less reversible.
Professional Service Firms
Law, medical, consulting and architectural practices with partnership economics.
Real Estate Organizations
Operators, developers and investment entities with complex ownership structures.
Nonprofit Organizations
Boards and executive teams accountable to funders, regulators and the public.
Financial Services Clients
Firms operating under heightened regulatory and reporting standards.
Employee Benefit Plans
ERISA-governed plans requiring specialized audit and assurance expertise.
Commercial Enterprises
Established businesses where accuracy, controls and forecasting drive the next decade.
Audit & Assurance
Trusted by organizations where accuracy matters.
Most CPA firms do not maintain genuine audit capability. We do. RAE was built around assurance — the discipline of independently testing the numbers that boards, lenders, regulators and funders rely on.
Practiced. Independent. Defensible.
