Martin began his career in alternative energy in a somewhat unorthodox place: as a decorated officer on a nuclear submarine in the U.S. Navy. He has held sales and marketing positions at various tech companies, including Cisco, Siebel, Insightful and Pure Networks. Prior to running GAF Energy, he headed SunPower’s residential North American business and global commercial business and served as President of SunPower Capital. He is also a member of Phi Beta Kappa, and has a BS from the University of North Carolina and an MBA from Harvard University. His favorite roof is the top of his bike helmet when he’s out on the mountain bike trails in British Columbia.
