Originally from Buffalo, New York, Fahey was born into a large family of 13 siblings. He left home at 17 and hitch-hiked to Alaska. He backpacked through Europe, worked on an Israeli kubbutz and has spent time in Afghanistan assisting the newly established American University of Afghanistan, and launching a project to assist orphans in Kabul.
Fahey's recent humanitarian work has revolved around the U.S. Committee for Refugees and Immigrants, in which he has been focusing on the subject of warehousing, a practice in which the rights and mobility of refugees is restricted by a host country. Fahey's work specifically has addressed the subject of warehoused Sahrawi refugees in Algeria.
