About Opportunity Bank of Montana

Opportunity Bank of Montana opened our doors in 1922 in Helena, Montana as American Building & Loan. In 1972, we changed our name to American Savings & Loan Association. By 1980, the Bank had expanded our service area to include branch locations in Bozeman, Butte, and Townsend. In 1991, the Bank made the decision to convert our charter from a Savings & Loan to a Savings Bank and changed our name to American Federal Savings Bank to reflect this charter. Additional growth came in 2012 when the Bank announced the purchase of the seven Sterling Savings Bank locations in Montana, doubling our branch network and increasing our footprint across Montana. In 2014, the Bank applied to the State of Montana to change our charter from a Federal Savings & Loan to a State-Chartered Commercial Bank. Along with this change also came our  rebranded name of Opportunity Bank of Montana. In 2017 the Bank acquired Ruby Valley Bank, and in 2018 acquired Big Muddy Bancorp, further solidifying the Bank as the fourth-largest Montana-based bank and expanding our market presence.  In 2019, the bank announced our intent to acquire Western Bank of Wolf Point, expanding our branch delivery system to the hi-line. Once this acquisition is complete, Opportunity Bank will operate 22 full-service retail branches throughout Montana. 

Today, our customers remain the driving force behind our success. Our nearly century-long commitment to our customers and our communities has earned our reputation as a leader in community banking.
