Our Story

Firstmark Credit Union is San Antonio’s oldest state-chartered credit union in the city. We have proudly served the San Antonio community for over 70 years. We have approximately $700 million in assets and ten branch locations throughout San Antonio and the surrounding counties. Our credit union serves over 90,000 members with investment products and services, such as savings and checking accounts, CDs, credit cards and loans.

Roots in Education

We are proud of our roots in education. Firstmark Credit Union began as the San Antonio Teacher’s Credit Union, established in 1932 by teachers during the Great Depression to help all school employees. Over the years, membership has grown to include private school and college employees, and their family members.

Growth – You Can Join!

In 2002, we expanded our membership criteria by qualifying everyone who lives, works, worships or attends school in San Antonio and the counties surrounding Bexar; and changed our name to Firstmark Credit Union. As we grow, we remain committed to our partners in education by serving them as members and through our employees’ volunteer efforts.
