Service 1 Federal Credit Union was chartered August 7th, 1940 by employees of Continental Motors. The first office was located in the basement of the Time Office at Continental Motors in Muskegon, Michigan. The original founders of our Credit Union wanted a safe and friendly environment where they could save their money. The two services the credit union offered were savings and loans. In 1950 the credit union moved into an office on West Western Avenue in Muskegon where it continued to grow. Email id based on pattern
