About Us


Mainstreet Credit Union is here to help you navigate your financial journey by providing support, encouragement, and advice every step of the way. MCU is a not-for-profit financial institution wholly owned and operated by its members. Earnings are not paid to outside stockholders. Instead, they are returned to members in the form of lower loan rates, higher dividends on deposits and lower fees.
Originally chartered in 1953 as Northeast Johnson County Teachers’ Credit Union, our financial cooperative was first run by a group of passionate teachers whose goal was to help fellow educators with their finances. By 1962, the CU moved from a classroom in the Shawnee Mission School District to a rented office with one manager and two part-time employees.

For more than a decade, membership continued to grow, and smaller credit unions were acquired through mergers. In 1979, the credit union expanded its charter to include anyone living, working, or paid by a company in Johnson County, KS. To reflect its changing membership, the credit union’s name changed to The Credit Union of Johnson County.

Expansion continued when the charter was changed to include the entire Kansas City Metro Area in 2008. Growth fueled by mergers with smaller credit unions created more convenience for members with the addition of locations in Lawrence, Leavenworth, and Kansas City, Mo. To reflect its new presence outside of Johnson County, the credit union changed its name to Mainstreet Credit Union in February of 2010. Two more mergers added branch locations in in Kansas City, Kansas, and Bonner Springs in the same year.

Today, more than 61,000 members from a variety of companies, agencies, professions, and neighborhoods turn to Mainstreet Credit Union for their financial needs.

Additionally, Mainstreet Credit Union is a proud community leader. MCU supports may different community organization, including local school foundations, chambers, and hospitals.
