Always very helpful, everyone is very friendly. I don’t always have my deposit slip filled out and everyone is willing to look up numbers and finish filling it out. Melissa goes out of her way to meet the needs of her customers, and is always happy to help. She is very knowledgeable and personable!!!

We recently worked with Brady at the bank for assistance with the purchase of our first home. He did an excellent job keeping in contact with us throughout the process and was always just a phone call away for any questions we had. As first-time home owners, we weren’t sure what to expect but Brady had the answers to all of our (many) questions. We are so thankful for Brady and ASB for making sure this process went smoothly. I highly recommend this bank for any of your banking needs. Locally owned, it is a bank to trust.

In the spring of 1987, five families who all were deeply rooted in Southern Iowa with a variety of business interests came together with a common vision.  Their vision was to ensure that families and businesses in their community would have choices in where to do their banking.  April, 1987 was at the deepest time of the economic struggles across Iowa and throughout the Midwest, with many businesses and families struggling financially. The new American State Bank opened its doors on April 24, 1987 at 1000 Jeffreys Drive in Osceola, Iowa.  The new bank assumed the deposits and acquired the assets of the failed Osceola State Bank, which had been at the same location.

American State Bank grew rapidly in its first few years by showing the community “What a Bank Should Be”.  The bank began with $800,000 capital and total assets of less than $8 million in 1987 and has steadily grown to more than $110 million of assets and $10 million capital today.  We established a presence in downtown Osceola when we acquired the branch office of First Central Bank at 101 N. Main Street in 1990, and expanded our footprint into Decatur County AND Northern Missouri when we opened another branch office at 801 E. Main Street in Lamoni, Iowa in 1998.   In July of 2011, the bank purchased certain assets of Exchange State Bank’s branch in Winterset, Iowa.  Financial Center services were added to that market in November of 2013.

Our growth and success has been driven by a solid commitment to our communities, an experienced and loyal staff, and a consistent responsiveness to our customers’ needs.

Early on, our founders laid out the Core Values of American State Bank that all associates are expected to abide by:
Honesty and Integrity - A community bank’s reputation is its most valuable resource.
Commitment To Our Customers - ASB is committed to respecting your privacy and protecting your financial resources while providing the highest possible level of quality financial services.
