Dutton State Bank has merged with Opportunity Bank!

Welcome to Opportunity Bank of Montana! The merger of four Montana branches of Big Muddy Bancorp with Opportunity Bank of Montana became official January 1, 2019. This event joins local banks that share a commitment to serving Montana communities.  We are pleased to bring Big Muddy Bancorp and Opportunity Bank customers together, and we look forward to serving your financial needs for many years. Much will stay the same when you become an Opportunity Bank customer:

So what is changing?
• You’ll now have access to enhanced products and services, including real estate mortgages, higher lending limits, and wealth management.
• We plan to combine our systems in March 2019. You will get plenty of advance notice to learn about any changes to your products or services and to assure the conversion does not inconvenience you. Please watch your mail in early February for a detailed conversion guide.

We measure our success by the success of the communities we serve. I’m proud to include Townsend, Denton, Dutton and Choteau among those communities. We look forward to being your community bank.
