Experience Convenient, Local Banking

Marlborough Savings Bank and North Middlesex Savings Banks have joined forces to create a bank that not only provides the conveniences that people demand, but the services and support that people need. This bank is Main Street Bank. As two mutual banks that have been in our communities for generations, we share the same values. We do all we can to support one another in a quest for a greater quality of life. Committed to making our communities stronger, we provide a full range of products and services that meet the needs of individuals, families and businesses; the personal attention to guide smart decisions; and support for the organizations that share our commitment to helping others. In addition, our combined institutions will offer enhanced benefits such as increased lending capacity, a larger network of branches and ATMs, and allow us to continue our legacy of being a responsible neighbor while delivering easy, hassle-free banking.

We do this because, like those we serve, we believe: Our lives are richer when we support one another. This is the guiding principle for how Main Street Bank does business.
