It all began on November 3, 1997, when local developer, Hank Schechert, created a new neighborhood East of Yuma and wanted to form a bank based on the same sense of community, friendly service, and down-to-earth attitude. Over the following fourteen years, Foothills Bank expanded its Arizona operations to Prescott and Casa Grande. In 2017, Foothills Bank became a division of Glacier Bank, which is owned by Glacier Bancorp, Inc. (GBCI), a regional bank holding company headquartered in Kalispell, Montana. This enabled Foothills Bank to continue serving local communities with the resources of a much larger bank. In 2020, State Bank of Arizona and its Mohave State Bank and Country Bank brands joined Foothills Bank, which more than doubled its footprint throughout Arizona.
