It is my honor and pleasure to serve as the Director of Public Works for Contra Costa County. Having served the citizens of our County in various capacities within our Department for over 28 years prior to being named the Director I had the opportunity to learn and grow in an organizational culture that strives for continuous improvement. Our mission is to deliver cost effective, safe, reliable and sustainable projects, programs and quality services as well as provide support services that are competitive, attentive, responsive, efficient, safe and high quality to our customers and fellow County Departments. We, as a team, work toward that mission daily. I am privileged to work with qualified and dedicated employees that take pride in being part of the communities we help to maintain. Building relationships and communication is important to us and we are committed to fostering long term strong, positive relationships with our partners and our customers.

Contra Costa County Public Works Department became the first County in California to be accredited by the American Public Works Association in July 2001 and we were re-accredited in 2004, 2008, 2012 and 2016. We continue to review and improve our work processes and are now re-evaluated for accreditation on a four-year cycle.
