About First Security Bank
True Bankers, Real Expertise
These days, there’s no shortage of financial options, but there is a short supply of true bankers. At First Security Bank we are bankers who offer sound financial advice and real world understanding of ag markets, capital equipment loans/leasing, mortgages and vehicle loans.
A Comprehensive Approach to Finance
At First Security Bank, we believe it’s not only our job, but also our responsibility, to know every facet of finance. This allows us to see the larger picture and understand how each aspect affects the other. Using this broader view, we can provide sound financial advice, support and services to you – our customer and most valued asset.
With eleven locations, First Security Bank offers the size, stability, lending capabilities and understanding you rely on for your personal and business needs. We’re not too big to forget the names of our loyal customers, or understand the reason they bank with us.

Investing in Our Communities
Being a responsible financial institution means giving back. We proudly support our communities beyond banking, offering scholarships and funding local initiatives. In 1993, our owner, Lloyd Amundson, established the L.A. Amundson Scholarship Fund with a $5 million endowment. Since then, Lloyd and his wife, Barbara, have donated over $3 million to students and have created additional endowments to support other community programs.
At First Security Bank, we are more than bankers—we are neighbors, partners, and advocates for a stronger future.
