About Sterling State Bank: A Local Bank Focused On Our Customers. Since the day we opened our doors in 1958, Sterling State Bank has been locally owned and operated. We have many years of experience, involvement, and investment in Minnesota’s local communities. Over the years, our full-service bank has flourished and grown to include insurance, commercial lending, and mortgage lending so we have the opportunity to more fully meet our clients’ needs. At Sterling State Bank, we believe banking is about relationships. We believe it’s paramount to understand and serve our clients with unsurpassed customer service, first-rate products, state-of-the-art technology processes, and rigorous security systems. We love to facilitate new business development, help existing local businesses grow, and to be the “family bank” everyone can count on for checking, savings, investments, and insurance needs.
