Firm Profile


After many years spent working at prestigious Boston firms where she gained valuable tax experience, Susan Archambault saw a need for a new type of accounting firm: one that combined the services of a family trust office and tax services model of quality expertise without losing sight of a client’s individuality. In December 1990, Susan filled that void in the accounting industry by founding ARCHAMBAULT & ASSOCIATES, a boutique accounting firm that combines the quality and sophistication of a large firm with the personality and price of a small practice. Decades later, ARCHAMBAULT & ASSOCIATES’ team of experienced professionals continues to embrace the core philosophy of service and to build long-term relationships with clients.

We invite you to get to know the members of our team better.
