About Members Source Credit Union
Who We Are
Members Source Credit Union has been part of the Northwest Indiana community since 1935. Originally established to serve employees of Northern Indiana Public Service Company (NIPSCO), we’ve grown into a full-service credit union proudly headquartered in Merrillville, IN.
Today, we serve more than 6,200 members and manage over $93 million in assets across three convenient branch locations in Merrillville, Griffith, and Dyer. We’re not a big national bank — we’re your neighbors, and every decision we make is guided by what’s best for the people who live and work right here in Lake County.
Whether you’re opening your first checking account or planning for retirement, our team is here with personal attention, competitive rates, and the kind of service that keeps families coming back for generations.
Who Can Join
If you live or work in Lake, Porter, Jasper, or LaPorte County, you’re welcome here. You can also join if an immediate family member already has an account with us. That means whether you’re in Merrillville, Crown Point, Hobart, Hammond, Schererville, Highland, Munster, or anywhere across the region there’s a place for you at Members Source.
