  • Convenience Services
  • Consumer and Real Estate Loans
  • MEMBERS Financial Services
    (investment and insurance services)

In addition to these low-cost financial services, the staff of Mainstreet Credit Union strives to provide each member with extraordinary service - service befitting an owner of a financial institution.

Great Rates - Great Service!


Select Employee Groups, or SEGs, are companies that have elected to offer the benefits of Mainstreet Credit Union to their employees. Membership costs nothing to the employer.

How will your company benefit by offering Credit Union membership?
Today's tight job market allows individuals to be selective. The value of a company's benefits package can be a deciding factor.

How employees benefit
National surveys show that Credit Unions charge lower fees for many services and provide better service to consumers than other financial institutions. Credit Unions also help build better lives by providing consumer education, a safe place for saving and access to loans at reasonable rates. Payroll Deduction and Direct Deposit are two examples of the many time-saving services available. A financially-stable employee is a happy and long-term employee.

How do employees join and/or get Mainstreet Credit Union information?
Employees can open Share Accounts during an open enrollment on-site at the company or stop by any one of our convenient branch offices. A Business Development Representative can make presentations to employees, host an open enrollment, and provide print marketing materials - paycheck stuffers, brochures, posters, and New Hire Information Pages for orientation packets, all at no cost to the employer.
