Mark Harmon and Pam Dawber have been married for over three decades, defying the odds of short-lived celebrity marriages. They have chosen to keep their family life private, having experienced fame from a young age. Their relationship began in 1986, and they got married in a low-key ceremony in 1987. Harmon has expressed his happiness and pride in his marriage, wearing his wedding ring as a reminder.

Dawber sacrificed her successful acting career to focus on their children. They have two children, Sean and Ty, who have also pursued careers in the entertainment industry.
