His parents were government professionals, and he and his four younger brothers grew up in a country where the danger of violence and death was an everyday reality. He was just 11 years old when the current civil war began, and when he turned 16 the conflict touched his own family and he fled to the United States to seek asylum. Two years later he was adopted by Doctors Alvin and Elizabeth Revell.
Makaya received his B.A. in International Relations from York College of Pennsylvania in 2015, receiving numerous awards including induction into Pi Sigma Alpha, Political Science Honor Society and selection for Who’s Who Among Students In American Colleges & Universities.
