Stephen Kilduff was born in 1958 in Baltimore, Maryland, and educated in Catholic (elementary) and public (high) schools there. He attended community college and then graduated Summa Cum Laude from the University of Baltimore in 1982 with a B.A. in English.

In the years since, he has written and published in most forms: op-ed pieces in the Baltimore Evening Sun (now defunct), fiction in The Sun Magazine (also defunct), poetry in Dancing Shadow Review, fiction in New York Press, and pretty much everything (lots of fiction, essays, news articles, many book reviews, music reviews, calendar picks) in Baltimore City Paper, where he was an editor and contributing writer in the late 80s/early 90s.

He started writing screenplays in 2000, writing five full-length scripts and attending screenwriting conferences/pitch sessions in Los Angeles, Santa Fe, and New York before coming to his senses and turning to playwriting in 2004. Having finally found his niche (it sure took long enough), he plans to stick with it for the foreseeable future.
