- Beth Chaim Congregation, Contra Costa County's Vital Jewish Community, provides a vibrant, embracing, enriching environment for over 500 residents in the Tri-Valley. Membership has grown from 82 families in 1995 to approximately 270 families today. Our members include local, state and global business leaders, elders, young families and children from birth through their 20s. Beth Chaim has become a vital Jewish community; a Community that offers worship, celebration, youth education, community service, continuing adult education and a portfolio of enriching events and programs. Thank you for your interest in Beth Chaim. We welcome you to join our special Jewish house of worship. We are committed to building a Jewish community where members are encouraged to share of themselves as well as to support and sustain each other as we celebrate Judaism. Please come and experience the warmth of our community and the joyfulness of our Shabbat services, which are held every Friday evening at 7:30 p.m. (or 7:00 p.m. if the service is a Family Shabbat). All services are held at The Danville Congregational Church at 989 San Ramon Valley Blvd., Danville.
