Our Round Rock branch was our first facility in Williamson county. The branch, conveniently located west of I-35 on the north side of Round Rock Ave. (also known as RM 620), has served the Round Rock community since 1994. This branch features a full-service lobby, drive-thru, ATMs, and personal service from helpful, friendly faces, and we offer great rates on savings accounts, Totally Free checking®, share certificates, all kinds of loans, and Mastercard® credit and debit cards with rewards.
