UC Berkeley
I’ve been lucky enough to enjoy success during my time at DHC, but no accomplishments are more important to me than the relationships I’ve forged with its founder Don Charles, its family of employees, and those clients I can truly call friends. My consistent goal is to create an environment that brings out the best in those around me and elicits passion for an industry constantly faced with new and exciting challenges.
I’ve always enjoyed a balance between striving to build new and efficient systems, while preserving the history and environment I’ve grown up in. As my work provides an outlet for the first, I spend my home life outdoors and working on creative projects with my kids like rainwater collection systems and home zip lines.
