Gibbs

Mark worked as a Carpenter before making a success of his acting career, which is interesting in that he is always shown on NCIS working on a wooden boat frame in his basement.  Mark started his career making guest spots on "Adam-12" and "Emergency."  Mark was also a guest star on "Ozzie's Girls" with Ozzie and Harriet Nelson, who were his sisters in-laws, as his sister was married to Ricky Nelson. Mark is best known for his work on "NCIS" as Gibbs, one of our favorite shows.

Mark was the starting quarterback for the UCLA Bruins for the 1972 & 73 seasons, finishing with a record of 17-5.  The highlight of his football career may be the upset of the National Champion Nebraska Cornhuskers in 1973.  Mark's father, Tom Harmon, was an All-American and Heisman Trophy winner for the University of Michigan.
