celebrating 90 years
Since 1932, Security Bank has been serving the fine residents of South Dakota. Originally chartered in Tyndall and now serving Chancellor and Viborg, South Dakota, and Heron Lake and Jackson, Minnesota. We are a South Dakota, independently owned and managed organization.
Through advanced banking technology and commitment to superior customer service, we are growing into new markets and providing new opportunities for the people who live there. As a local Midwest business, we continually strive to take your banking experience to the next level.
We've grown a lot over the past 90 years, but relationships and community support will always be the theme of our story.
