MidUSA Credit Union


In November 1934, 50 Armco Steel employees founded the Armco Employees Credit Union to help each other obtain low-interest loans in times of sickness, death, or emergency. That small group eventually grew to encompass three office locations and over 70 Select Employee Groups eligible for membership. In 1994, the name changed from Armco Employees Credit Union to MidFirst Credit Union, Inc. to better represent the diversity in the membership.

In 2001, MidFirst Credit Union obtained what is called a “Community Charter” from the State of Ohio to open MidFirst membership to anyone in Butler and Warren Counties. In 2008, MidFirst obtained an additional Community Charter for Montgomery County. These charters allow the credit union to serve anyone who lives, works, worships, or attends school in Butler, Warren or Montgomery County.

In 2010, the name changed to MidUSA Credit UnionTM as a result of our continued interest in expanding into new markets while continuing to serve our existing membership with great products and services. The MidUSA name reflects the credit union’s proud history, financial strength and stability, as well as lets the public know that MidUSA is open for membership to virtually anyone in the markets the credit union serves.

Today, MidUSA serves approximately 20,000 members, including the employees, families, and retirees of over 200 Select Employer Groups, and operates five branches in Middletown, Kettering, Trenton, and Liberty Township.
