The oldest of four children of an Air Force officer and Executive Secretary, Madison grew up in military housing in Roswell, New Mexico, Renton, Washington and Okinawa, Japan. On returning to the U.S. his family settled in Salisbury, N.C. and his parents separated. His mother then proceeded to raise the four kids alone and maintain a full time job. The family later moved to Charlotte where Madison spent his teen years.
At 15 Madison volunteered as apprentice for the Charlotte Summer Theatre, a large Summer stock company where he was taught to design and build sets while learning stage craft and appearing in the chorus of various musicals such as Guys and Dolls, Oklahoma, Brigadoon, The Desert Song, etc. This led to long involvement with the Charlotte Little Theatre, voted among the top ten community theaters in America. There, while appearing in several productions, he won the Most Promising Newcomer award for his portrayal of Jimmy Curry in The Rainmaker.
Flunking out of high school due to demands of theatre work, and maintaining a full time job to help support the family, Madison finally left Charlotte for Roanoke Island where he appeared for the Summer as Manteo in the outdoor drama The Lost Colony. From The Outer Banks he went to Princeton N.J, there appearing in two seasons of classical repertory at McCarter Theater.
Moving to New York he acted Off Broadway in The Alchemist before leaving for England to attend The Bristol Old Vic Theatre School for a year to further his training. On returning to America Madison resettled in New York where he appeared again Off Broadway in Arms and The Man and The Firebugs.
During this time Madison spent a season each, performing in repertory at Trinity Square Theater in Providence, R.I. and Front Street Theater in Memphis, Tennessee.
Once again in New York, he worked a The La Mama ETC and then formed the folk group MorganMasonDowns, which played the famous Greenwich Village coffee houses and then recorded an album for Roulette Records. The group also played The Tonight Show and a CBS TV special. Appearing briefly on Broadway in Hair, Madison went on tour with the group to promote their album.
Back in New York, Madison spent a year on The Edge of Night.Then he appeared in the Broadway road production of Diamond Studs, going with the show for a season to Ford's Theater in Washington, D.C.
From Washington Madison moved to Los Angeles where he has appeared over a hundred thirty movies and television shows, as well as over 250 commercials. He has been spokesman for Listerine, Napa Batteries, McDonald's, as well as appearing as The Shell Answer Man.
Madison also received the prestigious MovieGuide Award for his performance in the Lifetime movie, Amish Grace.
