David Sigura was born in Morristown, New Jersey. He and his family moved to the California Bay Area when he was 10 months old. Falling in love with the craft early on, Sigura began participating in a number of theater conservatories as a child. Acting was put on hold through his teen years in order to focus on education and to work in the family business. Sigura attended the University of California, Santa Barbara. He re-discovered his passion for acting in the latter portion of his college career; he acted in numerous student films, took acting classes and participated in student film festivals. Sigura graduated with a degree in Sociology. It was after receiving his degree that he decided to pursue acting as a full-time career.
