Mark Harmon and his wife Pam Dawber have built a long-lasting marriage spanning nearly four decades while raising two sons who have each carved out careers in the entertainment industry. One of their children even appeared on-screen alongside his father in the long-running drama NCIS.
A Private Hollywood Family
Actor Mark Harmon is widely recognized for his role as Leroy Jethro Gibbs in NCIS and other notable screen performances. Off-screen, he shares a long marriage with actress Pam Dawber, known for Mork & Mindy. The couple, who married in 1987, have consistently kept their personal lives away from public attention.
Despite both working in Hollywood, they have intentionally maintained a low-profile family life, focusing on home and privacy rather than public exposure or social media presence. Their approach has also influenced their children, who similarly avoid excessive public attention.
Sean Harmon: Actor, Producer, and On-Screen Gibbs
Their eldest son, Sean Harmon, was born in April 1988 in Burbank, California. Now in his late 30s, he initially worked in stunt performance and coordination before transitioning into acting and production.
Coming from a family deeply rooted in entertainment, Sean has often acknowledged that filmmaking and acting have always been part of his life path. His work eventually brought him into direct collaboration with his father’s most famous role.
In 2008, he portrayed a younger version of Gibbs in flashback scenes during the sixth season of NCIS, a rare on-screen moment linking the real-life father-son relationship with their fictional counterpart. He later expanded into production work, including involvement in NCIS: Origins, where he worked alongside his father.
Beyond television and film, Sean has also moved into producing roles and is now a father himself. In 2025, he welcomed a son with his partner, further extending the family lineage.
Mark Harmon has publicly expressed pride in his son’s dedication and professionalism, emphasizing his strong work ethic and commitment to the craft.
Ty Harmon: Behind-the-Scenes Writer in Film and TV
The couple’s younger son, Ty Harmon, was born in June 1992 in Los Angeles. Unlike his brother, Ty has built his career primarily behind the camera as a writer.
Over the years, he has contributed to a variety of film and television projects, including work connected to major productions such as Venom, Thor: Love and Thunder, The Lord of the Rings: The Rings of Power, Masters of the Air, and For All Mankind. He also collaborated with his brother on an early short film project in 2012.
Ty tends to maintain a private lifestyle, though he is married and occasionally shares personal milestones. His professional focus remains firmly in screenwriting and development work within the industry.
A Family Rooted in Entertainment
While both sons have followed creative paths, they have each chosen different directions within the industry—one in acting and production, the other in writing and development.
Mark Harmon has consistently expressed pride in both of his children, noting their discipline and commitment to their respective careers. Despite their public careers, the family continues to prioritize privacy, stability, and life away from constant media attention.
