Advantage One Credit Union has served the Downriver community since 1952. Our commitment to provide superior member service and quality products and services has remained our prime focus throughout our growth. Why would you want to join Advantage One Credit Union? That's easy. Because we're a not-for-profit financial cooperative, we charge lower fees and have lower loan rates than most big banks. And maybe best of all, we're committed to improving the financial security of everyone who walks through our doors, as we offer everything from friendly personal service to free financial education. Can you join Advantage One? Under our charter, we are permitted to serve the entire state of Michigan. If you work, worship, or attend school in Michigan, you're eligible. Membership is also open to immediate family members of existing AOCU account holders. This also includes stepchildren, stepparents, step siblings, and adopted children.
