KCSB was founded in 1884 has held the charter continuously since that time. From 1955 until 1999 KCSB was owned by the families of the late Robert (Rob) and Sally Marget and Helen and the late George Marget, Jr. Rob and George Marget and their brother John (Jack) had purchased the bank from Harry and Bert Helscher who owned the bank. In 1999 the bank was acquired by Fountain View Bancorp, Inc. of Sigourney, a bank holding company founded by a group of local investors who wanted to assure the bank would remain locally owned. KCSB was recently honored by the Iowa Department of Economic Development and the Iowa Association of Business and Industry as a "Century Business", a business owned and operated in the state of Iowa for more than 100 years.

KCSB has five locations. Our main office is located at 201 South Jefferson, on the southeast corner of the Square, in Sigourney. The bank moved here in 1971, relocating one block from the original bank location. Since 1971, the bank building has undergone several remodels to assure our state-of-the-art facility meet the ever-changing needs of our customers. In 2006, KCSB opened our first branch located in Williamsburg Iowa at 500 Highland Avenue, ¼ mile south of I-80 and the Tanger Outlet Mall. In 2010, KCSB added three additional branches in Deep River, Gibson, and Keswick.
