Security First Bank of North Dakota is a community bank that is locally owned and operated by a family. We have four primary banking locations in Center, New Salem, Mandan, and Bismarck, with an additional part-time office in Almont. Our bank has a rich history, having been founded by Morton County residents in New Salem during the 1920s with a mission to serve the local community. Originally known as First State Bank, we opened our doors in New Salem on January 7, 1925, and have since been committed to providing exceptional banking services to our customers.
