Lorenzo Lamas was born in Santa Monica and grew up in Southern California. At thirteen, he moved with his mother, stage and screen actress Arlene Dahl, to New York City. Lorenzo attended the Admiral Farragut Academy, a military school, where he developed his character and discipline that would benefit him for the rest of his life. During his four years at Farragut, he became interested in athletics and lettered in wrestling and track. Lorenzo was president of his senior class and 2nd in charge of a Battalion of 300 cadets. He graduated with the intention of enrolling in the University of California to study veterinary medicine. During the summer of this year, however, Lorenzo visited his father Fernando on the film set of The Cheap Detective. It was at this point that Lorenzo decided to purse a career in acting and to follow his father's advice to enroll in Tony Barr's actors' studio.
Lorenzo' first big break came at nineteen, when he won the role of Tom Chisum in the blockbuster film Grease. From there, he was cast in several television roles until he got another lucky break, being cast in the nighttime soap Falcon Crest. Lorenzo had been studying the martial art, Tae Kwon Do, and the producers quickly realized how important it was to incorporate this skill into his character's action scenes. After nine years on Falcon Crest, Lorenzo's action hero credentials were established and he made a number of action movies including Snake Eater, Body Rock, and CIA Target Alexa, which he also directed.
Lorenzo was by this point a black belt and met with Stephen Cannell to develop an action television series, Renegade. For the next five years, He filmed 110 episodes of this show, producing and occasionally directing as well as acting in the series. Air America followed, whetting Lorenzo's appetite for aviation. Thanks to the many hours this series required he spent behind the controls of an airplane, Lorenzo became a certified private pilot in 1997 and later got his commercial helicopter rating as well.
Actively pursuing his career as an actor, director and producer, Lorenzo stays very busy. He is also co-chair on several children's charities, including Make a Wish, MDA and The Children's Angel Foundation.
In April 2011, Lamas changed his name to Lorenzo Craig.
