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. All three Wisconsin offices were united under the new name of American Bank & Trust, WI. The year 2002 brought added growth with an office in Fennimore, WI. In July 2006, American Bank’s newest office opened in Platteville, WI.

American Trust’s Financial Management Group, is one of the largest independent Iowa-based trust operations offering wealth management, retirement, investment, and brokerage services. As of March 31, 2018, assets under management exceed $2.6 billion. In January 2005, FMG began to offer wealth management services to clients in California through its affiliation with ATBancorp.
