Sunflower Bank

About Us

Whether you know us as Sunflower Bank, First National 1870, or Guardian Mortgage, our philosophy is simple: we offer a full range of financial products that create possibility in the lives we touch and the communities we serve. We value the needs of each customer and partner with them to help achieve their goals through innovative solutions and locally informed decision-making.

We are proud of our longevity and the long-term relationships it represents. Sunflower Bank was founded in 1892. We operate as First National 1870 in New Mexico and El Paso, Texas to honor roots dating to 1870. Additionally, Guardian Mortgage, our residential mortgage division, has helped generations of valued customers across our footprint and beyond realize their dreams of homeownership.

Today, with approximately $5 billion in assets, we are headquartered in Denver, CO and provide a full range of banking services including personal, small business, commercial, wealth management, credit cards, home loans, and more.
