Our History
Since 1869, First Bank Blue Earth has been a trusted financial partner for the people, businesses, and agricultural communities of Southern Minnesota.
Founded on November 13, 1869, by Nathanial Chadbourn as a private bank, our institution has evolved alongside the community it serves. Through periods of growth, change, and economic development, the bank has remained committed to supporting local families, farms, businesses, and community organizations.
Over the years, the bank has operated under several names:
- Bank of Chadbourn Brothers and Company
- City Bank of Blue Earth City
- Merchants and Farmers Bank of Blue Earth City
- Farmers and Merchants State Bank
- First National Bank of Blue Earth
- First Bank Blue Earth
Throughout more than 150 years of service, our mission has remained consistent: helping our communities grow and prosper through strong financial leadership, personal relationships, and local decision-making.
A significant milestone occurred in 1987 when First National Bank of Blue Earth was purchased from First Bank System Minneapolis by a group of local investors, returning local ownership and strengthening the bank's commitment to the community.
In 2006, the bank converted to a Minnesota state charter and adopted the name First Bank Blue Earth, reflecting both its heritage and its continued focus on serving local customers.
Today, First Bank Blue Earth employs more than 30 team members across the bank and insurance agency, including a dedicated team of lenders who help individuals, families, farmers, and businesses achieve their financial goals.
While banking has changed considerably since 1869, our commitment to local service has not. First Bank Blue Earth continues to operate as an independent community bank where decisions are made locally, relationships matter, and customers come first.
Looking to the Future
More than 150 years after our founding, our story is still being written. As First Bank Blue Earth looks to the future, we remain dedicated to strengthening our communities, supporting local economic growth, and helping our customers achieve their financial goals. By combining innovative banking solutions with the personal service and local decision-making that have defined us for generations, we will continue to be a trusted financial partner for individuals, families, farmers, and businesses. We are proud of our heritage, grateful for the trust our customers place in us, and excited to serve the communities of Southern Minnesota for generations to come.
First Bank Blue Earth: Local Leadership. Trusted Relationships. A Commitment to the Future.
