Sun Light & Power is both a California Benefit Corporation and a Certified B Corp.

“I have led Sun Light & Power since its inception over 43 years ago. I have no formal business training; my degree is in mechanical engineering and I am a professional engineer. If there is a “secret to my success” I would say it is due to doing work that I love to do and surrounding myself with people who have the same sense of mission that I feel. Working with a team that I know is always pulling right alongside me makes for a hugely satisfying work experience every day.”
