Gregory Clifford "Greg" Montgomery is the husband of Dharma Montgomery, son of Edward and Kitty Montgomery, son-in-law of Larry Finkelstein and Abby O'Neil and brother-in-law of Harry Finkelstein and a main character on Dharma and Greg. He is portrayed by Thomas Gibson.
Greg is a lawyer by profession and a graduate of an alumnus of elite schools, Phillips Exeter Academy, Harvard University, and Stanford Law School. He is an upright, uptight, decent, though sometimes surprisingly open-minded man. Greg grew up in a conservative Republican family. Greg's life was hopelessly banal before he met Dharma, whom he married her on their first date. Since then, he has played straight man to the antics of his eccentric wife. Though his relationship with Dharma has been rocky at times, Greg has never been shown to regret their marriage.
