History

Security Trust and Savings Bank was founded in 1908 by L. E. Ballou and L. E. Ballou, Jr. Over the years the presidency has been transferred from L. E. Ballou to L. E. Ballou, Jr. to E. L. Ballou (son of L. E. Ballou, Jr.) to David H. Dvergsten (E. L. Ballou's son-in-law). We are proud to maintain a family owned bank that has grown from $50 thousand in total assets to nearly $90 million in total assets. We opened the first remote drive-up facility in Storm Lake in 1961 and have added a drive-up ATM, a convenience store ATM and a 24 hour lobby ATM to better serve our customers. We tripled our main bank space in 1985 with a major expansion and remodeling. Since 1908 we have adapted to changes in the banking industry in order to serve our customers more efficiently.
