Our Mission

Trona Valley is a caring partner dedicated to your financial success.


History

During the 1960s in Southwest Wyoming, FMC Corporation was mining something called trona ore. Trona ore is used to make soda ash, which is a component in making products such as glass, laundry detergent, and baking soda. FMC Corporation was and still is the largest producer of trona ore in the world.


After a significant number of employees were hired by FMC Corporation, the desire for a credit union became apparent. On July 16, 1963, FMC Employees Federal Credit Union was born.


From 1963 to 1988, FMC Corporation was the only select employment group banking with FMC Employees Federal Credit Union. That all changed in 1989, when FMC Employees Federal Credit Union merged with Stauffer Big Island Federal Credit Union and became known as Trona Valley Federal Credit Union. Under our new name, we were able to add 79 select employment groups, increasing the size of membership significantly.


In 1999, we received our community charter. This allowed us to serve any individual who lives, works, worships, or attends school in Southwest Wyoming.


In 2012, we received approval to expand our membership again. We now offer our services and products in ten counties: Sweetwater, Sublette, Lincoln, Uinta, Carbon, and Teton Counties in Wyoming and Rich, Morgan, Summit, and Daggett Counties in Utah.


Over the years a lot has changed, but even more has stayed the same. When you come into Trona Valley Federal Credit Union, you can always count on personable service with a smile.
