Martin first began to work as an actor in Seattle in the early 70's and he soon ended up as a founding member of the Empty Space Company where he did some 23 plays, often performing in three different shows a day. This led to working at other theatres in Seattle including ACT and Intiman Theater. Around 1976 he moved to New York and studied with Michael Howard. Since then he has played leading roles at many of our best regional theaters. He has also appeared on Broadway and Off-Broadway as well as doing occasional television and film and many commercials.

In the 80's with the encouragement of Paul Giovanni (director and author of The Crucifer of Blood) Martin began to direct. First as Paul's assistant director and then at different theatres around the country. For a long time he also taught acting with his wife and partner Susan Greenhill, first for Manhattan Class Company and then in their own studio. Presently, instead of teaching an ongoing class, he prefers to coach actors for auditions.
