Why Join Westmark Credit Union?


bank icon

We're not a bank

As a full-service consumer financial cooperative, our profits are re-invested for the benefit of our members, not shareholders.


We're Competitive

As a non-profit, we reinvest our income back into the credit union, providing you with better interest rates and lower fees.

Safe Icon

Your Funds Are Protected

Your savings is federally insured up to $250,000 by the National Credit Union Administration, a U.S. Government Agency. 


We're Convenient

We're accessible online, in person at one of our branch locations, or just a phone call away. However you prefer to handle your finances, we make it easy for you.

To become a member, you must open a Primary Savings Account and deposit a minimum of $5.00.

The minimum $5.00 per member deposit must be maintained in Primary Savings at all times to receive the advantages of membership, including voting for Board of Directors and the use of Westmark products and services. (A member must be 16 years of age or older to vote).
