Who We Are

Our mission is to unite women in Alameda and Contra Costa counties through collective philanthropy. We aim to make a significant difference in the lives of those in need by supporting deserving local nonprofit organizations that serve them.

Membership in Impact100 East Bay provides women an opportunity to be part of a greater effort by funding community projects in a way that is far more impactful than one can achieve alone. It also provides an opportunity to meet other dynamic women who are passionate about becoming aware of and responding to needs in our communities.

We seek to be representative of the broad range of women who make up our community. We are mothers, daughters, sisters, friends; and our faces reflect those of all who make Northern California’s East Bay the varied community it is.
