Founded To Create Opportunity For Our Clients, Our Staff, And Our Community

Baker Newman Noyes (BNN) is a tax, assurance, and advisory firm entrusted by individuals and leading organizations to deliver effective accounting and financial solutions with diligence, vision, and responsive client service. We draw on our deep experience and foster collaboration between our practice groups to find solutions to any situation. Our clients are our motivation and the measure of our success.

BNN attracts talented professionals from prestigious accounting and advisory firms in want of a place where complex issues are solved through teamwork and where relationships with our clients and our community take priority.

From deep roots to proven leader

With roots going back nearly 100 years, BNN was formed in Portland, Maine in 1995 when Newman, Noyes & Associates merged with partners of KPMG Peat Marwick Portland. Four years later, BNN opened an office in Manchester, New Hampshire, and then another in Portsmouth in 2003.

An expansion into Boston in 2010 and a series of BNN-led mergers in 2015 established Baker Newman Noyes as one of the fastest-growing regional accounting and advisory firms in New England. With its 5th office in Woburn, Massachusetts, BNN is among the largest regional firms in Maine, New Hampshire and Massachusetts.

Serving our communities

We are only as strong as the communities we serve. Whether participating in a fundraiser, serving on a non-profit board, partnering with a local school, volunteering to clean up a local park, or serving food at a shelter, we strive to be a meaningful part of our communities. Employees throughout BNN answer the call to “give back” through participation and leadership in our hometowns.
