Here is everything you need to know about Sean Harmon’s personal and professional life.

Age, parents, family, and education

Sean Harmon was born on April 25, 1988, in Burbank, California.

His father is one of the highest-paid TV actors and is best known for his role in a TV show called St. Elsewhere, as well as for role in called Chicago Hope and NCIS.

His first acting gig was him starring in a short film called ‘Catholic Schoolgirl Chainsaw Showdown,’ an action-horror film directed by himself.

Apart from his parents and sibling, he also has a vast number of talented and famous family members.

Personality Traits

Sean Harmon turned 32 this year. Based on his birth date he is a Taurus. A Taurus born on this day of the month is known to have a loving nature, are committed, and have strong determination. Such traits might explain how he has been working hard to make his own identity without his father’s help.

He is 5’11” inches (182 cm) and is muscular with a mesomorph body type. Asides from his acting career, Sean also likes to kick-box and surf.


Although his career choice causes him to be in the spotlight frequently, he is a reserved person who does not like to make his personal life public.

He probably inherited such characteristics from his parents, who have never cared for attention throughout their career.

On October 30, 2012, Sean was seen with a mystery girl as his date for the inauguration ceremony for Mark Harmon at the Hollywood Walk of Fame in Los Angeles, California. In his Instagram account we can see her with Courtney Prather. It seems they both are in a relationship.
