Our History

HQ_History_1000

Firstmark Credit Union (Formerly San Antonio Teachers Credit Union) is a member-owned, locally controlled, not-for-profit financial cooperative.

In 1932, ten teachers chartered the institution, giving it the honor of being the oldest state-chartered credit union in San Antonio, Texas. Firstmark Credit Union held its first official Board Meeting on December 7, 1932, and its first annual meeting on January 14, 1933. As of December 31, 1932, Firstmark had accumulated a total of 40 members, total assets were $475, total loans were $300, and had a total of five borrowers.

The Credit Union was first located at Fox Tech High School until 1947 when it moved to the San Antonio Teachers Council on Adams Street. Those facilities were outgrown in 1966 and the office was moved to 303 South Santa Rosa Street in downtown San Antonio where it remained for 14 years. In May 1980, Firstmark moved to 10730 Gulfdale, and six years later, the first financial center opened in July of ‘86 at 2327 Southwest Military Drive.

In 2013, Firstmark Credit Union acquired Southside Credit Union to develop and strengthen their relationships with members throughout south San Antonio. Firstmark gained three additional financial centers through the expansion and acquired St. Joseph’s Credit Union in 2015, expanding the membership and helping the credit union achieve over $1 billion in assets. With both mergers, members of these communities were able to take advantage of the expanded products and services available, including technology and a larger ATM network.

Firstmark’s dependable, courteous service has established long-term relationships with loyal members who depend on the Credit Union to fulfill their financial needs, and remains committed to their well-being and giving back to the communities it serves.
