Administrative Staff


Philip Arca
Interim Executive Director

Philip Arca has demonstrated a lifelong commitment to social justice that involves direct support of individuals, systemic change, sustainability, creativity and the joy of allowing all to realize their fullest potential.   On a practitioner level, he is a seasoned turnaround leader with broad and deep experience.

Most recently, he has been Interim Executive Director for a national network of employment lawyers committed to justice/equity in the workplace, an art/science center, a county wide foster youth program, senior nutrition services, a youth science outreach effort in the East Bay, a law center in Marin, while also consulting with the Ella Baker Center and on the Advisory Board of the Sustainable Business Alliance. Philip was recently accepted as a Charter Member of the National Association of Accredited Interim Executive Directors (NAAIED).

He is formerly the Executive Director of a $7 million, 85 employee, and 800 volunteer, faith-based social services organization working throughout Alameda County.

He enjoys theater, ukulele/guitar, Dragonboat paddling, cycling, motorcycling and comes from a family of three sisters and with his partner Sherry has two daughters. If requested to be a dog, would be a basset hound — improbable with a consequently necessary sense of a humor.

He aspires to be a useful ally for all of the fine work that the Rainbow Community Center pursues in Contra Costa County.
