About Opportunity Bank of Montana

Opportunity Bank of Montana is a $1 billion community bank with 24 full-service bank branches throughout Montana along with mortgage, agriculture and digital banking services.

Opportunity Bank of Montana opened our doors in Helena, Montana in 1922 as American Building and Loan. In 1972, the Bank changed our name to American Savings & Loan Association. In 1991, the Bank changed our charter from a Savings & Loan to a Savings Bank and accordingly changed our name to American Federal Savings Bank. In 2014, the Bank applied to the State of Montana to convert our charter from a Federal Savings & Loan to a State Chartered Bank. This change provided an opportunity to re-brand ourselves as Opportunity Bank of Montana.

The Bank acquired TwinCo, Inc. in 2018, Big Muddy Bancorp in 2019, and Western Holding Company of Wolf Point in January 2020, solidifying our position as the fourth largest Bank headquartered in Montana, and expanding our branch network into the Ruby Valley, Golden Triangle, and Hi-Line regions. Opportunity Bank of Montana now operates 24 full-service bank branches throughout Montana with locations in Big Timber, Billings, Bozeman, Butte, Choteau, Denton, Dutton, Great Falls, Hamilton, Helena, Livingston, Missoula, Sheridan, Townsend, Twin Bridges and Wolf Point.

Our nearly century-long commitment to our customers and our communities has earned our reputation as a leader in community banking.

Giving Back

At our heart we are a Montana community bank. We are part of each community we serve. We volunteer, donate, build, educate, and strive to make our communities stronger. We believe being part of community means giving back. We invest in our communities with a variety of sponsorships, grants, donations, and hours of staff volunteer time. In 2019, Opportunity Bank employees across the state contributed over 5,938 hours of hands-on support and professional leadership to local organizations.
