Main Street Bank was originally formed when two locally owned community banks, Marlborough Savings Bank and North Middlesex Savings Bank joined forces in 2017. Both financial institutions have been proudly serving and supporting the MetroWest and North Central Massachusetts communities since 1860 and 1885, respectively. We look really good for our age, though! Our long-standing history has shaped who we are today. The strength, commitment, and genuine caring of our people have defined the character of Main Street Bank. We are united under a culture that strives every day to contribute to our communities by providing customer-focused, innovative products and services for individuals, families, local businesses, and community organizations. Not to mention, it’s easy for you to get in contact with our employees. For over 100 years, we have believed in people helping people. That may not be what every bank or financial institution does, but we like to think we’re a little different from them anyway. Our people live, work and raise their families here. We are part of the communities we proudly serve and truly believe that our lives are richer when we support one another. Have a Question? Our lives are richer when we support one another. This is the guiding principle for how Main Street Bank does business.
