Who We Are

Members, Leadership & Staff

At its heart, WGA is a membership organization.

Our Members elect officers, decide where monies are spent, and what kind of organization they’d like to have. WGA Committees carry out this substantial work. Our Leadership, Steering Committee and The Community Foundation for Northeast Florida guide and support our efforts, directed by our Governance documents. Guided by the principle “one Member, one vote”, we all have equal say and the same opportunities to become involved.

The Community Foundation staff supports the Women’s Giving Alliance in many ways. Pictured here are Amber Jubinsky, Stephanie Garry Garfunkel, Nikki Sabol, Wanda Willis, Kathleen Shaw, and Grace Sacerdote.
