Take a look at these photos of young Patrick Dempsey, which feature his childhood and teenage years all the way through his early career as an actor. Best known for his role as Dr. Derek Shepherd in the popular television series “Grey’s Anatomy,” Dempsey is also a race car driver on the side. Born in January 1966, before he was dubbed “McDreamy” he was discovered after receiving an invitation for an on-stage performance of Torch Song Trilogy. After scoring the role, he toured with the company from Philadelphia for four months. His career in the film industry was birthed after his performance in “In The Mood” at the age of 21. Dempsey has gained wide-spread exposure for his good looks and great acting abilities, but few people probably know how impressive his race car driving skills are: he has competed in numerous events, including 24 Hours of Le Mans, Rolex 24 at Daytona sports car race and Tecate SCORE Baja 1000 off-road race. In fact, he declared that he would permanently walk away from his acting career if he could make it big in the racing arena.
