He joined the cast of Lassie in 1971 as Dale Mitchell and stayed with the show until 1973. In 1977 he got the role of Jon Baker in CHiPs and became a heartthrob along with co-star Erik Estrada. He left the show after its 5th season in 1982 and went on to produce the award winning Ray Bradbury Theater for HBO and guest star in many popular TV series such as Murder She Wrote and MacGyver. He also appeared in the motion pictures Mission Manila, Dirty Dozen: Next Mission and several made-for-TV movies.
Today he busies himself with business interests and various philanthropic and charity projects, but still takes time for the occasional acting job, much to his fans’ delight. His latest role was a cameo appearance as himself playing Jon Baker on the Christmas 2009 episode of 30 Rock.
