Christopher DeWan has had a long career as a dramaturg, director, writer, and consultant in new play development, and has worked in the literary departments of theatres including Manhattan Theatre Club, the McCarter, the Wilma, the Walnut Street Theatre, the Mark Taper Forum, and the Playhouse Theatre in London. He spent years as co-artistic director of Hollywood's acclaimed Theatre of NOTE, and is a co-creator of The Edge of the World Theater Festival, an annual celebration of the small theatres of Los Angeles which ran from 1999 through 2003 and was, during its time, the city's only theatre fringe festival.

He has written several produced stageplays. His play Clyt at Home (a musical adaptation of The Oresteia co-authored with Katharine Noon) was shortlisted as one of the best plays in Los Angeles by Backstage West and the LA Weekly, and performed at UCLA's Common Ground Festival, the Ko Festival of Performance in Amherst, MA, the NACL Catskill Festival of New Theatre, and the John Anson Ford Amphitheatre's "Inside the Ford." The show was later remounted as part of a series called Home Siege Home at the Getty Villa.

He has worked on the publishing staff of Theatre Communications Group and acted as web editor for American Theatre magazine.

He recently participated in a narrative theatre experiment called The Box, created by Padraic Duffy and Hans Gelpke and produced and performed by Sacred Fools Theatre Company. Other collaborators on the project include Paula Cizmar, Jon Jory, Caridad Svich, and Mac Wellman.
