At First State Bank Southwest, the health and well-being of our customers, employees, and communities are our top priority. We care deeply about the communities we serve and believe that by working together, we can help mitigate the spread and impact of COVID-19.
Until further notice, access to the inside of our branches (except our Rushmore office) will not be available. Our drive-up and walk-up services will remain available during regular hours at all offices and offer most banking services. As always, we will be available by phone to assist you with account information, phone transfers, online banking help, etc.


We understand that these are unusual circumstances, and we’re committed to working with you as the situation evolves.

We greatly appreciate your patience and cooperation.

First State Bank Southwest

Serving You Since 1903

We have seen our bank grow from a very small humble beginning in 1903 to a bank with six offices. Many new products and services have been added during the years for improved service for the convenience of you, our customers.
Our story is a tribute to two groups of people. Good customers who put their faith and trust in First State Bank Southwest and our employees who have worked hard to provide the quality service our customers deserve.
We look forward to serving you in the future!
