Our Purpose

1st MidAmerica was established in 1934 with the sole purpose of providing financial products and services for employees of Olin Corporation and their family members. While Olin Corporation continues to be our main sponsor, we serve the financial needs of approximately 60 other select employee groups. In addition, our community charter allows us to open our membership to anyone who lives, works or maintains an address in one of eight Illinois counties: Madison, Macoupin, Montgomery, Bond, Fayette, Jersey, Greene and Calhoun.

At 1st MidAmerica, our members are entitled to certain privileges not offered by other financial institutions. We provide the friendly service of a small town institution with the financial strength and services of a large financial institution. We believe in the philosophy of people helping people and offer our members higher interest on dividends and lower interest rates for borrowing money.

That is how we have become the 5th largest credit union in the St. Louis metro area – by knowing and meeting the financial needs of more than 44,000 members, by maintaining more than 70 years of long-term financial soundness and by being a preeminent service provider.
