Ilan Sigura: An Integral Career

By James Florence, Diamond Certified Resource Reporter

Graham Jones: A Unexpected Direction

By James Florence, Diamond Certified Resource Reporter

SAN FRANCISCO — Graham Jones never planned on becoming a plumber, but when his original professional pathway diverged, that’s the direction it took him in. “I was actually going to automotive school, with plans to become a mechanic,” he recounts. “However, at a certain point I realized it wasn’t the right career for me, mostly because I didn’t want to be stuck in the same place every day.
