Vision Leadership

About SFB

A source of strength since 1934 — We are a locally owned, community bank focused on business, agriculture, and the insurance industry.

Our History


The country was in the depths of the Great Depression when we opened our doors for the first time in Durand, WI. We quickly became a trusted depository for our clients and a financial resource for area businesses, farmers, and residents.

Today, we continue to be a locally owned, community bank focused on business, agriculture, and the insurance industry. SFB has about $850 million in assets and has more than 130 employees with offices in Alma Center, Black River Falls, Bloomer, Durand, Eau Claire, Ladysmith and River Falls.

Our Vision


Our vision is to be the best business and ag bank and top employer in each of the markets we serve.

We will always strive to provide products and services that exceed our customers' needs and provides guidance that enable them to succeed.
