FirsTier Bank traces its organizational history back to 1955 when a group of local business leaders and bankers founded the Kimball County Bank in Kimball, Nebraska, with a mission to foster economic prosperity in the surrounding agricultural community. In 1963, banker Joel Wiens purchased The Bank of Kimball, initiating decades of strategic growth and operational expansion. Over the 1990s and 2000s, the financial institution adopted the FirsTier Bank brand, expanding its branch network across Nebraska, Wyoming, and Colorado. Under the leadership of the Wiens family, FirsTier Bank scaled into a regional community banking institution managing over a billion dollars in assets, offering commercial lending, residential mortgages, personal deposits, and business financial solutions anchored in relationship-focused banking.
