Mid America Bank was chartered on January 3, 1910, as the Footville State Bank, located in the Village of Footville in Rock County, Wisconsin. It faithfully served Footville and the surrounding community for eight decades. Eventually, however, the bank identified an opportunity to serve a broader population in Rock County.
First, in September of 1989, the Footville State Bank was renamed Mid America Bank. Then, in May of the following year, it opened a full service branch office ten miles east in Janesville, Rock County's largest city. Mid America Bank opened yet another full service branch office in January, 1999, in nearby Williams Bay.
