Atkinson's early years were shaped by the region’s rugged lifestyle, which taught him to be resourceful and appreciate the support of his community. These values guided him through his career in the U.S. Navy and public service. He also inherited a rich cultural legacy from his ancestors, a society that follows the matriarchal line, and who belonged to the Gitlaan clan of the Xpi’hanaḵ house in the Tsimshian nation.
