Thomas Gibson was born on July 3, 1962. Originally from Charleston, South Carolina, he is the youngest of four siblings born to Charles and Beth Gibson, who raised their children according to the Roman Catholic faith.
Gibson, famous for roles on "Dharma and Greg," "Chicago Hope" and "Criminal Minds," developed an early interest in the performing arts. At age 9, he began acting in children's theater productions. While attending college, he interned at the Alabama Shakespeare Festival, which led to a Juilliard Drama Division scholarship.
After graduation, Gibson added numerous off-Broadway roles to his resume and appeared in film and television with increasing frequency until finally landing "Chicago Hope" in 1994.
