in Jack & Jill of America, Inc.

Thank you for your interest in Jack and Jill of America, Inc., Contra Costa County Chapter. We appreciate your desire to join our chapter. There are several chapters in the Bay Area. In order to join ours, you must live within the boundaries of Contra Costa County. 

Membership can be obtained via legacy status or invitation. 

Membership via Invitation


Prospective members must be sponsored by a current member in good standing. We encourage interested mothers to make contact with Contra Costa County Chapter members to learn about specific member guidelines and procedures. 

Fill out the Membership Interest form below to find out more about our organization and how you can become part of our Jack & Jill family. 

New members begin their introduction to our chapter in September and sponsors submit applications for prospective new mothers in January. 


Membership Via Legacy Status


Legacy status is granted to each child (male or female) who graduates from a Jack and Jill Chapter and whose mother is a member in good standing at the time of the child’s graduation from the chapter. Once the child desires to enter Jack and Jill through their Legacy Status the legacy will be verified through the chapter by completing and submitting the legacy application.


The application should be filled out and forwarded to the current chapter president of the chapter in which he/she graduated out from. If at the time the chapter cannot verify the legacy, the chapter files at headquarters will be researched to verify Legacy. If a Legacy certificate was filed for the child it will be in the Chapter Files in Headquarters.
