About Us

American Trust has been a community pillar since 1911. It has grown to strengthen the products, services, and financial management provided to clients while retaining the integrity and commitment that can only be found through a community bank. After three generations of growth, ATBancorp (originally incorporated as Amtrust, Inc.) was formed in 1985 to serve as the bank holding company for American Trust & Savings Bank. Today ATBancorp is a two-bank holding company for American Trust and American Bank & Trust, Wisconsin. Headquartered in Dubuque, IA, ATBancorp is a banking organization with assets in excess of approximately $1.6 billion serving nine communities through seventeen banking facilities in Eastern and Central Iowa and Southwest Wisconsin.

In 1998, ATBancorp acquired the Cuba City State Bank in Cuba City and Hazel Green, WI. ATBancorp announced the expansion of services in Wisconsin with a new office in Lancaster in 2001.

In July 2006, American Bank’s newest office opened in Platteville, WI.
