After leaving Howard University (Theater Arts major), he became an original member of the City Kids Repertory, a theater company that performed in schools in effort to bring relevant productions to high-risk kids. Following a confrontation with fellow cast member Patrick Dempsey on the set of Grey's Anatomy (2005), it was reported that the altercation was related to Washington's use of the epithet "faggot" towards their co-star T.R. Knight. In response to press queries about the incident, he denied that accusation in the backstage area at the 2007 Golden Globe Awards. However, Knight and other cast members later stated that he did use the word (January 2007). Has two sons Isaiah, Tyme and one daughter, Iman.
