River Bank was formed on June 30, 1991 when three banks located along the Mississippi River in Stoddard, Ferryville and DeSoto were merged together. In September 1993, in an effort to better serve our La Crosse customers, a branch office was opened on Mormon Coulee Road. In November 1996, River Bank expanded its service to the Holmen/Onalaska area. In November 1999, an office was opened in Sparta. In May 2004, a seventh location was opened on the north side of La Crosse. In October 2005, River Bank merged with Farmers State Bank with locations in Bangor, Barre Mills, and Rockland. In December 2007, River Bank built another location in Westby. In October 2010, River Bank consolidated the Rockland location with Barre Mills and Bangor and opened a new location in Coon Valley.
River Bank’s primary mission is to serve the banking needs of Crawford, Vernon, Monroe, La Crosse and Trempealeau Counties. Prior to the formation of River Bank, the original banks had the reputation of being the banks that were friendly, understood their customers' needs and would go the extra distance for service. This continues to be the hallmark of River Bank in its expansion into the Sparta, Onalaska, Holmen, Bangor, Westby and Coon Valley markets.
