ONE AMERICAN BANK

ONE AMERICAN BANK Member FDIC. Equal Housing Lender. ONE AMERICAN BANK was founded in 1883, six years before South Dakota was granted statehood.

Originally known as the Bank of Centerville, our bank was chartered by early settlers looking to place their life’s financial holdings in a safe institution. Through the Great Depression, the Dirty 30s, World War II, and the Ag Crisis of the 1980s; this bank maintained a sound and secure financial condition and to this day is an extremely well capitalized bank. In 2011, we became ONE AMERICAN BANK

when the Lund Family acquired the shares of the bank. The Lund’s were innovative business leaders who brought over 40 years of experience in banking services. With a strong management team in place and dedicated staff, we continue to proudly serve customers both locally and nationally. Today, as an extremely well capitalized financial institution, the Bank is embracing technology with new products and services. But, as much as these technological advancements will enhance and simplify the way you conduct your financial business, it’s our committed team of professionals at ONE AMERICAN BANK that will be there to listen to you, to assist you, and help answer any questions that technology simply can’t resolve.

Today, we pause to remember and honor the lives lost on September 11, 2001. We reflect on the courage of first responders, the resilience of our communities, and the spirit of unity that emerged during one of our nation's most difficult days.

As we remember, we also recognize the importance of coming together, supporting one another, and strengthening the communities we call home.

We will never forget. MEMBER FDIC.
