Sean Koriat: An Energy-Saving Career

By James Florence, Diamond Certified Resource Reporter

PALO ALTO — Upon moving to California from his native country of Israel, Sean Koriat traded a career of saving lives for one of saving energy. “Before I came to the United States, I worked as a paramedic in Israel,” he remembers. “I met my wife on a vacation to California and ended up moving here permanently.” When it came time for him to establish a new professional livelihood, Sean decided to try his hand at a trade that had always interested him: HVAC. “The idea of making people’s homes more energy-efficient and comfortable really appealed to me. I started out working for a local HVAC company and eventually decided to start my own company that specialized in attic cleaning and renovations.”

Chris Morimoto: An Unexpected Transition

By James Florence, Diamond Certified Resource Reporter

BENICIA — Having a good personality goes a long way, but for Chris Morimoto, it led to a totally unexpected career transition. “Back in 2001, I called a local HVAC company to get a consultation for replacing my furnace,” he recounts. “At the end of the appointment, the technician said, ‘You’re a pretty cool guy, you should meet my boss.’ At the time, I was interested in switching careers, so I decided to take his advice.

Nate Missildine: Expanding Horizons

By James Florence, Diamond Certified Resource Reporter

Liam Caldwell: Homegrown Talent

By James Florence, Diamond Certified Resource Reporter

Simon Spark: An Artistic Inspiration

By James Florence, Diamond Certified Resource Reporter

SAN FRANCISCO — Simon Spark has always been an artistic person, but he never expected to apply his talents to the realm of residential remodeling. “I started working in the construction field to support myself while attending college, where I studied fine arts,” he remembers. “After graduating, I spent the next 10 years working as a professional artist, doing primarily mixed media sculptures and drawings. Eventually, in my mid-30s, I came to a crossroads where I wanted to start a family and needed a more financially lucrative livelihood. So, I got my contractor’s license and went into business doing residential building and remodeling in San Francisco.”
