Mark Harmon, the veteran actor widely recognised for his role as Leroy Jethro Gibbs in the long-running television series NCIS, has taken a moment to reflect on his family life, particularly his two sons, Sean and Ty. Harmon, who has been married to actress Pam Dawber since 1987, has consistently prioritised his home life while navigating his successful career in Hollywood.

The couple welcomed their first son, Sean, on April 25, 1988, shortly after their wedding. Their second son, Ty, was born on June 25, 1992. When it comes to family matters, Mark and Pam have chosen to maintain a low profile, steering clear of the limelight to ensure a degree of normalcy for their children. In a recent conversation with PEOPLE magazine, Harmon described how his role as a father influenced his decision to take on NCIS. He noted, “I was trying to stay home more with a young family,” reflecting on the delicate balance between his professional and personal responsibilities.
Both Sean and Ty have followed in their parents’ footsteps into the entertainment industry, albeit in different capacities. Sean has embraced roles in front of the camera. Notably, he portrayed a younger version of Gibbs on NCIS, appearing in several episodes of the show. He has also made contributions as a stunt performer and coordinator, showcasing his skills in various productions, including television shows and films.
Sean’s achievements do not stop at acting and stunts. He also took on the role of executive producer for the NCIS spinoff, NCIS: Origins, where he portrayed an FBI agent named Casey Bloom. His contributions to the show indicate not only a passion for the craft but also a sense of pride in continuing the family legacy. In a 2020 interview with Entertainment Tonight, Harmon expressed his pride in his son’s hard work, saying, “I’m proud of both our boys, and they work hard at what they do.”
Meanwhile, his younger brother Ty has taken a different path within the industry. Working primarily behind the scenes, he is a screenwriter and visual effects artist. He collaborated with Sean on a short film titled Catholic Schoolgirl Chainsaw Showdown, which was released in 2012. Ty’s skills have also landed him credits on major projects, including films like The Marvels and series such as For All Mankind.
Both Sean and Ty are married, adding a new layer to the Harmon family dynamic. Sean married producer Courtney Prather Harmon in November 2022, and they welcomed their first child, a son named Cooper, in May 2025, making Mark and Pam delighted first-time grandparents. Ty’s marital journey also began in February 2021 when he married Madeline Harmon. The couple enjoys life with two dogs, as shared through Ty’s social media updates.
As they seek to carve out their own identities within the entertainment sphere, both Sean and Ty reflect the work ethic and determination instilled in them by their parents. Mark and Pam’s dedication to providing a supportive home environment appears to have successfully equipped their sons to navigate the complexities of show business.
In a world where celebrity offspring often find themselves overshadowed by their famous parents, the Harmon brothers are gradually establishing their unique paths while also honouring their family’s rich history in acting and production. As Mark Harmon continues to reflect on his career and family life, it’s clear that both elements are intricately connected, shaping not just his legacy but that of his sons as well. The future remains bright for the Harmon family, with multiple talents emerging from their ranks while continuing to uphold their values of hard work and dedication.
