Membership Information

You are welcome to join whenever you are ready.

The MOB has no attendance requirement. The only membership requirement is that you are a mom, pregnant, or TTC, and you reside in the San Francisco Bay Area city of Brentwood (94513).

Annual dues are $54. Our membership year runs October 1st – September 30th, but if you join between April 1st and September 30th, your dues will be prorated to $34. Membership dues cover the cost of the majority of the club’s activities.

Members communicate via a private Facebook group, with smaller groups for our various playgroups and sub-clubs. This is a great opportunity to draw on the resources of our members to find valuable assistance with local businesses, doctors, day-care options, schools and more.

Membership dues may be paid by e-check, debit/credit card, or Paypal.

If you have any additional questions, please contact our Membership Coordinator at If you’re ready to join, fill out the form below to begin the process. All applicants are subject to approval.
