Our Story


Pinnacle Credit Union was founded in 1926 under the name Atlanta Teachers Credit Union. We are currently the second oldest credit union in the state of Georgia. Since opening we have grown into a full-service financial institution. Like other credit unions, Pinnacle is a not-for-profit organization; meaning profits are returned to members in the form of better rates on savings, lower interest rates on loans and fewer fees. The credit union is owned by its members and led by the board of directors that is formed from the membership.

Since 2014, Pinnacle Credit Union has undergone major changes to help improve the member experience. Things like online banking, mobile apps, and depositing checks with your phone are all new to the membership. Management and the Pinnacle team continue to work towards improvement always keeping the membership at the focus of all developments.

What is a credit union?

Credit unions began back in 1852 in Germany as a not-for-profit financial cooperative. Since then they have continued with a cooperative identity of “based on the values of self-help, self-responsibility, democracy, equality, equity and solidarity. In the tradition of their founders, co-operative members believe in the ethical values of honesty, openness, social responsibility and caring for others.” (International Co-operative Alliance definition)

Throughout the years, credit unions have continued to put the focus on the membership. The credit union family continues to work together to provide conveniences all over. One of those conveniences is the shared branching network. Pinnacle and thousands of other credit unions allow their members to visit any credit union in the shared branching network to access their funds. That means nationwide, you as a member can easily make deposits and withdrawals at other credit unions.
