We thrive on working with clients in need of exceptional accounting and tax preparation and planning services. Since our founding, we have achieved this goal by treating every client who walks through our doors with individual attention and courtesy.

While many of our business and individual clients reside in the greater Boston area, we support clients throughout the United States. Our typical business client has sales ranging from $1M to $80M. We also represent individuals seeking a high degree of consulting services in addition to annual tax preparation.
