MountainOne History

MountainOne is proud to celebrate our long standing history with our Mountaineers, valued customers, and community.

Did you know that we have deep roots in both the Berkshires and the South Shore? Born in the hills of the Berkshires, MountainOne originally dates back to 1848 with the formation of its very first entity, North Adams Savings Bank. From there, two more community banks, four local insurance agencies, and one financial advisory firm joined the herd.

Despite different beginnings, what truly unifies us today is our shared mission to o deliver solutions of real value that help individuals, businesses, and community institutions manage their financial lives with clarity and confidence. MountainOne has grown to employ over 180 Mountaineers across our regions, and offers a full suite of banking, lending, insurance and investment services to our customers. We are immensely proud of our unwavering commitment to the communities we serve, and we look forward to continuing that work for years and years to come.

Learn all about our exciting history below. Hey, we look pretty young for our age!
