Community Groups

CBJ takes pride in maintaining a community where members form strong and lasting relationships with each other. We’re grateful for the care of fellow congregants during difficult times, as well as the love and support we feel during joyful times.

We foster meaningful relationships is by creating the environment throughout synagogue life where people can share their stories with each other, whether as part of a formal program (such as our “Fourth Friday” speaker series or intergenerational interviews) or more informally (check out our Shabbat morning “welcome nosh” in the front lobby.)

Community Groups at CBJ

We encourage members to get to know each other through a wide range of interest groups and social opportunities. A few of our groups and initiatives are listed below. If you’re curious about a social or demographic interest group that you don’t see represented, you can always reach out to our Membership Engagement Director, Rebecca Schwartz, at or 650-366-8481 ext. 371.

Affinity Groups

Members with particular hobbies or special interests are encouraged to organize affinity groups as a way to form deeper relationships in our community. In the past, members have organized affinity groups around bike riding, sporting events, hiking, movies or theater, and mah jong. If you’re interested in getting involved, our Membership Engagement Director, Rebecca Schwartz, at or 650-366-8481 ext. 371.

Book Clubs

We currently have two book clubs, the CBJ Book Group, which hosts occasional events, and the Women’s Book Group, which meets on the meets the second Thursday of each month, 7:30-9pm. (Check the calendar for upcoming events and meetings.)


When CBJ members are going through difficult life events, such as longterm illness or grieving, our community cares. Our Cares team provides home-cooked meals to members in need as well as assistance with transportation. Contact Daphna Dror ( to volunteer or to request assistance. Join us in our kitchen for cooking days!


Some members join together in smaller fellowship circles (often grouped by similar stage of life or similarly aged children) to form a chavurah. These groups of six to 10 members or families gather monthly for Shabbat dinner, playdates in the park, or whatever they enjoy.


Interfaith couples are welcomed to CBJ with joy as part of a philosophy that has been led and modeled by Rabbi Ezray. Our approach may be described as “radically inclusive.” Non-Jewish partners are embraced and appreciated for who they are without expectation that they’ll pursue a path to become Jewish. Our non-Jewish members are vital to every aspect of synagogue life.

They are welcomed to participate in every way that feels right to them, whether it’s through education, social action, Board activity, or participation in services.

Mah Jong

CBJ hosts mah jongg games twice a month on Tuesday evenings. Games are open to all skill levels, and refresher or beginning lessons are available upon request. A smaller group meets on Mondays at noon at CBJ. Contact Stephanie Lachtman at for details.

Men’s Club

men's club

Our Men’s Club brings together men of all ages for social activities and networking. Past activities have included brewing our own beer and getting together at CBJ and at neighborhood locations. No membership needed – drop in any time. Contact the office for more information 650-366-8481 or

Neighborhood Groups

Our neighborhood groups bring together up to two dozen or more families who live in the same town or area for get-togethers several times per year. Members have organized neighborhood Shabbat dinners, havdallah dessert gatherings, Sukkah brunches, picnics and playdates in the park.



Members occasionally organize hikes, bike rides, kayaking trips and other outdoor activities. Watch for invites on our calendar, our weekly newsletter, and/or CBJ Community group on Facebook. Or feel free to organize your own. For details on how to share your invite with other members, contact our Membership Engagement Director, Rebecca Schwartz.


CBJ’s active Sisterhood gathers women of all ages for social activities, support, wisdom, learning, recreation, spiritual endeavors and service to our synagogue and the greater community. We meet monthly to celebrate the new moon (Rosh Chodesh), and to explore life together. We have engaged in guided mediation, learned to bake Jewish foods, planned and created rituals, studied with inspiring teachers, listened to each other’s stories, created art, enjoyed music, gone on field trips, and have eaten a lot of food. We are intergenerational and our goal is to foster community. Dues are $36/year — join Sisterhood and make it yours.

Youth & Teens

In 2015, CBJ and Peninsula Sinai Congregation of Foster City combined efforts to create a USY (United Synagogue Youth) Chapter in the New Frontier region. We are called NPUSY (North Peninsula United Synagogue Youth). Kadima USY is for 6th-7th graders, and our USY chapter is for 8th-12th graders. NPUSY’ers learn about Israel affairs, engage in social action, and take part in fun chapter and regional events. For more information, contact Stacy Goldstein, Youth Commissioner, at
