Our newest branch office serves members in Sioux City, IA!

A successful merger via a history of helping.

As Premier Credit Union continues to grow and serve more members in Iowa, we expanded our in-house services to assist with specific needs more directly. Premier Lending Alliance, a wholly owned subsidiary mortgage CUSO of Premier Credit Union, was created to help other credit unions with their mortgage lending. This lead to a nearly 10-year relationship with The Municipal Federal Credit Union (TMFCU) of Sioux City, Iowa. When it was decided in the best interests of the members and staff to merge with another financial institution, Premier Credit Union was top of mind! After a successful vote from their membership, TMFCU officially joined Premier Credit Union in May of 2024, and all members and staff were welcomed into the Premier family.

More counties and locations to serve you.

Joining the field of membership counties that Premier already serves in central Iowa, we now add the counties of Plymouth and Woodbury in Western Iowa. Premier will also add their first membership counties outside the state of Iowa, by now serving Union County in South Dakota and the counties of Dixon and Dakota in Nebraska. Located at 103 S. Fairmount Street in Sioux City, Premier now has another branch location to serve all our members, as well as offering exciting new products and services to members in that area.

Serving Sioux City Iowa since 1938.

TMFCU (Now Premier) serves anyone living or working in the above-mentioned counties, including the cities of Sioux and South Sioux City, IA, Sergeant Bluff, IA, the Dakota Dunes, and more! We are thrilled to offer competitive rates and amazing products and services here, as well as our expertise in financial solutions for all aspects of life.
