Six years ago, painter and graphic designer Greg Mike lay unconscious in 6 feet of snow, the collarbone of his painting arm shattered, his arm badly lacerated. Doctors told him he might never paint again. Now, Mike has opened a solo show of dozens of paintings titled “Chapter New” in his own brand-new gallery in East Atlanta. Getting to this point from that deep snow was just one part of a much longer journey in Mike’s multiyear effort to open the new space.
