Get to Know Members Source Credit Union

We’ve been a part of the Northwest Indiana community since 1935, and everything we do is guided by a simple belief: your credit union should work for you, not the other way around. We’re headquartered in Merrillville with branches in Griffith and Dyer, and we serve anyone who lives or works in Lake, Porter, Jasper, or LaPorte County. We’re not a big national bank — we’re your neighbors, and we’re proud of it. Whether you’re curious about who we are, want to find a branch near you, or are ready to join, you’ll find everything you need below.
