He has written, directed, and performed in many corporate events all over the world for such companies as Walt Disney World, Ford Motor Company, Ernst & Young and Eckerd Drug, as well as having led many corporate training seminars in the application of improvisational techniques to the business world and to facilitate the creative development of students. He has also continued to do theater, performing in Central Florida with the Orlando Shakespeare Theater, Orlando Theater Project, Vine Theater and Mad Cow Theater in partnership with the Orlando Philharmonic Orchestra, as well as theaters in Los Angeles and Massachusetts.
