Mark Edinger grew up in Wyoming, where he learned to love adventure and the outdoors. It proved to be good training when he joined the U.S. Army. He started out as a helicopter mechanic and worked as a Cobra helicopter crew chief in Desert Storm. Edinger later became a Blackhawk pilot and flew medivac helicopters in Iraq before retiring with 21 years of service.
Today, Edinger works as a homemaker and enjoys developing and renewing connections with his children. He finds that post-traumatic stress disorder has robbed him of his zeal for the outdoors, and he hopes to regain that vigor during the expedition. Edinger wishes to connect with his peers and offer fellowship to others in need. He aspires to stop exercising avoidance and begin using alchemy to harness life experience into optimism.
