Dutton State Bank opened for business on September 17, 1960 in the present facility. Originally there were only two employees. A drive-up was added in 1973 and an addition to the north of the bank was completed in 1990. The first branch opened in White Sulphur Springs, MT in 2008.

The bank was formed after two local businessmen, Ray Van Heel and Jonas Johnson, proposed that a bank in Dutton would be of great interest to the people of this area. The original stockholders were local businessmen, farmers, and residents of the area. The bank remains locally owned with over 150 stockholders, most of which still live and work in our trade area.

Directors elected the first year were: C. A. Callan, Carl Eklund, Rudy Fuhringer, Don Moore, James Cheetham, M. B. Bolland, and Clarence Phillips.

The Bank has grown to $21,136,000 in assets as of 12-31-07 and continues to serve the communities of Dutton and White Sulphur Springs and the surrounding areas as their local community bank. Current management consists of Shawn W. Dutton, President; Evelyn T. Habel, VP/Cashier; Craig Storle, Asst. Cashier, and Dallas Rasmussen, Branch Manager of the newly established White Sulphur Springs, Montana Branch.
