Mutual Savings Credit Union Banking

Mutual Savings was established in 1933 by eight Atlanta Gas Light Company employees who pooled their funds together to establish the Credit Union. Recall in 1933 it was the great depression when more than 5,000 banks failed and the unemployment rate peaked at twenty-five percent. It was a time when Atlanta Gas Light Company employees were in desperate need of inexpensive credit and reliable financial services. It cost 35 cents to get approval from Georgia’s Secretary of State and Mutual Savings Credit Union was born. Deposits and membership fees were stored in a cigar box – secured in the company’s safe. Over eighty years later, Mutual Savings now serves more than 6,000 members and manages over $70 million in assets. We pride ourselves in helping our members afford life.
