Jim Walters, founding chairman of Chattahoochee Bank of Georgia’s Board of Directors, has retired from the Gainesville bank he helped start in 2008.“Mr. Walters has been a driving force behind the success of our bank,” Chattahoochee Bank President and CEO Jody Lail said in a news release. “We were fortunate to have had the opportunity to draw on his knowledge and experience to guide us through the process of organization, opening our doors for business and growing to serve the community these last four years.”Walters was one of 12 organizing directors for the bank, located at 643 E.E. Butler Parkway, and led it as it grew to more than $95 million in assets. Recently the bank also earned a five-star superior rating from BauerFinancial Inc.Walters said his reason for retirement was simple: On Sept. 13, he reached the retirement age of 75, set when the bank was formed.“Initially when we formed the bank, our consultants said traditionally 70 is the retirement age we usually recommend to banks that we offer advice to,” he said.
