Frontier Bank was founded in 1932 by a group of local community leaders who decided to open a bank in their hometown.

A board of local directors governs the bank. In the tradition established by the initial board of directors, the current board is dedicated to the continuation of independent, community banking with local decisions for local customers.

We currently have locations in Rock Rapids, George, and Little Rock, Iowa, as well as in downtown Sioux Falls, South Dakota. Our headquarters is located in Rock Rapids, Iowa.

We strive to be a leader in banking technology and continue to provide services to our customers that enable them to conduct business more conveniently. We select technology solutions that benefit our customers directly, and we work to ensure that our customers are offered the best services and products available.

We invite you to join us.
