He is a multiple winner of the ASCAP Award, among other awards such as the America Music Center Award, Brannen-Cooper Fund Award, and the Minnesota Orchestra Honorable Mention.  “FredO,” as he is called by friends and colleagues was born in Secondi-Takoradi, near the Atlantic Coast in Ghana, West Africa.
