Since 1976, Bill McNamara has been in the electrical contracting business. He began helping out in the family business in Atascadero, where his dad started a family-run electrical service. When he was 13, he wired his first residential project and shortly thereafter knew he wanted to start a business of his own. In 1986, and started his contracting career at a race track for seven years called Sears Point, now referred to as Infineon Raceway. As Napa Valley's wine scene flourished, McNamara Electric expanded. The demand for electrical contractors increased as wineries were constructed. For a decade and a half, Bill subcontracted a trusted electrical contractor when required. At present, he focuses on emergency calls and smaller tasks.
He now lives on a ranch in Angwin, California. He sponsors a regional Sprint car racer, Britton Bock. He takes his tasks—whether at work or during his free time—with dedication and gives it his all.
