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 three-bank holding company for American Trust, American Bank & Trust–Wisconsin, and United American Bank in California. Headquartered in Dubuque, IA, ATBancorp is a banking organization with assets in excess of $900 million 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. President and CEO Chris J. Prange joined Cuba City State Bank in 1999. 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.

ATBancorp extended its footprint into other banking markets as well. In March 2003, the company became a significant investor in a new state-chartered bank formed in San Mateo, California. State chartered United American Bank (UAB) was formed in 2003 and is a community bank specializing in commercial and private banking services. The bank grew quickly, and by 2007 UAB had grown to four California banking offices in San Mateo, Sunnyvale, Half Moon Bay, and Redwood City.

The Financial Management Group division of American Trust continues to be a key strategic unit of the bank. With assets under management exceeding $1.2 billion, it is one of the largest independent Iowa-based operations in trust and related services. The Financial Management Group offers clients wealth management, retirement planning, investment, and brokerage services. In January 2005, the Financial Management Group began to offer wealth management services to United American Bank clients in California through its affiliation with ATBancorp.

In 2006, a new ATBancorp subsidiary was formed to serve as a Registered Investment Advisory (RIA) company in the Financial Management Group division. ATCapital Management provides strategic growth models and additional investment alternatives.

Throughout the years, ATBancorp has developed a strong reputation for providing outstanding service to its clients and strongly supporting its local communities. ATBancorp is proud of this tradition and looks forward to serving its clients and communities in the future.
