Educators
Firstmark Credit Union (formerly San Antonio Teachers Credit Union) is a member-owned, locally controlled not-for-profit financial cooperative. We were chartered in 1932, giving us the honor of being the oldest state-chartered credit union in San Antonio, Texas!
Firstmark Credit Union is committed to education. We recognize the enormous responsibility and transformative impact that teachers and education has on our children, families and in our communities.
