How Did We Get Here?

Marine was established in 1949 in Fond du Lac, Wisconsin, by hardworking people, for hardworking people.

With commitment to community as our guiding principle, we’ve since grown to numerous locations throughout Wisconsin, Iowa, Minnesota and Illinois where we serve over 80,000 members. It also inspired us to create the Marine Credit Union Foundation in 2014, which has raised over $1,500,000 and contributed to over 1,000 charitable causes so far.

Though we’ve enjoyed sustained growth through the years, we’ve never lost sight of our core values — courage, collaboration, compassion and commitment — or the greater community we serve.
