Opportunity Bank of Montana is a $1.2 billion community bank with 22 full-service bank branches throughout Montana along with ... mortgage, agriculture and digital banking services. 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. Our mission is to provide strong financial futures for Montanans. 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. Today, the Bank operates 22 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. Opportunity Bank is proud to be an Affirmative Action and Equal Opportunity Employer. ©2020 Opportunity Bank of Montana, all rights reserved. Member FDIC. Equal Housing Lender. read more
