Online Banking

Since 1922, Guaranty State Bank & Trust Co. has helped generations of families, businesses, and agricultural producers build their futures across Kansas. Founded through the merger of two local banks, Guaranty was built on a commitment to personal service, strong relationships, and helping our communities thrive. Over the past century, we have grown alongside the communities we serve while remaining true to the values that have guided us from the beginning.

Today, we’re proud to serve customers whose grandparents trusted us with their savings and estate planning, whose parents relied on us for business and agricultural lending, and who now turn to us for their first checking account, first mortgage, or next big opportunity. From establishing a trust for one generation to helping the next purchase a first home, we’re honored to be part of life’s most important milestones. While banking has evolved over the years, our commitment has remained the same: combining modern banking conveniences with the personalized service, local knowledge, and lasting relationships that only a community bank can provide.
