Coleman was a disc jockey for WGCL in Cleveland, Ohio in the late 1970s. This included the weekend of July 7–8, 1979, when that radio station presented his own take on American Top 40 after the station's refusal to air the "Top 40 Disco Songs" special for that weekend.
In the same period, Coleman appeared in several plays through Jerry Leonard's Heights Youth Theater ensemble. The plays were staged at Wiley Junior High School in University Heights, Ohio – just down the road from John Carroll University. Other famous performers who appeared in Leonard's plays include the actress Carol Kane.
Shortly before becoming a voice actor, he hosted a pair of dance shows for local television stations: We're Dancin' at WNEW in New York City (now WNYW) and The Dance Show at WSB-TV in Atlanta.[4][5]
