Our History
On June 1, 1950, ten employees of the Oak Ridge Gaseous Diffusion (K-25) Plant filed an application for a Federal Credit Union Charter. On June 13, 1950, K-25 Federal Credit Union’s charter was approved by the Bureau of Federal Credit Unions.
During the 1950s, K-25 Federal Credit Union conducted business from a small office at the K-25 site; now known as the Heritage Center at the East Tennessee Technology Park. On June 20, 1956, the credit union expanded into the south end of the K-25 site, occupying Wing D of Building K-1001.
After operations at the K‑25 enrichment complex ended, the Credit Union converted to a community charter in 2003 to more effectively serve its membership. The revised charter broadened membership to include residents across nine surrounding counties. Those who live, work, worship, or attend school in Anderson, Blount, Claiborne, Knox, Loudon, Morgan, Roane, Scott, or Union Counties are eligible to join.
On November 5, 2007, the Credit Union introduced its new name, Enrichment Federal Credit Union, honoring the scientific legacy of uranium enrichment at the historic K‑25 site while also reflecting our commitment to enrich the financial lives of our members and strengthen our presence in the communities we serve.
It’s all about enriching your financial future.
People helping people

- In November, we partnered with the Tennessee Credit Union League for their annual Grocery Giveaway, joining credit unions across East Tennessee to make a direct impact in our communities. Our team spent the day at a local grocery store, surprising shoppers by paying for their groceries and offering a moment of relief during a busy season. It was a meaningful reminder of what People Helping People truly looks like.
- In December, we partnered with East Tennessee Children’s Hospital to provide warm, comforting meals to families spending some of their hardest moments inside the hospital walls. It was a small gesture on our part, but for many of those families, it meant a moment of relief, a reminder that their community was standing beside them, and a little bit of hope during an incredibly difficult time.
- December is also when we hold our Annual Gloves of Love program, which was especially meaningful this time as we expanded it to all nine of our locations. Together, we were able to support 21 local schools and collect more than 7,000 gloves, hats, and scarves—helping keep children in our communities warm throughout the winter.
- We wrapped up the year with our newest cherished tradition—Santa Visits. Santa and Mrs. Claus traveled to our branches, greeting families, sharing smiles, and bringing a little extra magic to the season. Children enjoyed photos, stories, and Mrs. Claus’s cookies, creating joyful moments that perfectly closed out a year focused on community and connection.
