Kelly Callen, Chair, Alternative Energy Committee
Kelly’s passion for historical homes was sparked when she spent nearly two years restoring a Freeland, Michigan farmhouse that had been in her family for four generations. The home was rumored to have been the birthplace of several “Rin Tin Tin” puppies. Recently retired, she spent over a decade as an Executive Assistant to famed Atlanta architect John Portman. When she told Portman about Friends’ goal to make Mimosa the oldest Net Zero home in America, he commented that this achievement “would be REMARKABLE!” Kelly, her husband Todd, and their two children, all passionate environmentalists, live in Roswell.
