Ambrosi Donahue Congdon

As one of the leading CPA firms on the North Shore, Ambrosi Donahue Congdon traces its roots back to 1974. At that time, Tom Ambrosi, formerly associated with Touche Ross & Co. of New York, started practicing in Newburyport. In 1977, he joined forces with Mike Donahue of Arthur Andersen & Co. of Boston to establish Ambrosi Donahue & Co., P.C. In 1979, the firm acquired the local practice of George K. Leavey, P.A. and flourished in its State Street, Newburyport offices.

Continued growth of the firm, due in large part to the rapid development of the greater Newburyport commercial area, necessitated the need for new and larger office space. In 1982, Ambrosi Donahue renovated a historic brick dwelling near the corner of State and Harris Street, with the resulting modern office building containing more than 17,000 square feet of office space.

The firm continued to grow and prosper, expanding its client base through the lower Merrimack Valley, seacoast New Hampshire, and southern Maine. Together with other accounting and non-accounting professionals who joined the firm in the eighties and nineties, a team with even more depth and background was created.

In 1997, Ambrosi Donahue & Co., P.C., merged with the practice of Keith N. Congdon, CPA, an international accounting, audit and tax practice with considerable corporate and accounting expertise, to form Ambrosi Donahue Congdon & Co., P.C. Keith had originally developed this expertise through his association with Coopers & Lybrand in Hartford, Connecticut.
