From the moment her daughters entered school, Valerie became involved in the Hausner volunteer community, serving on both the Development Committee and the Purim Carnival Committee - bringing with her more than twenty years of nonprofit experience and an inherent love for Jewish community. Valerie’s passion stems from her upbringing in Upstate NY, where she and her family were entrenched as volunteers and leaders in local Jewish communal institutions, and from her deep sense of pride for her family’s history and dedication to tradition. As a teenager and young adult, Valerie lived in Israel where she fell in love with the country and the people, further solidifying her commitment to Jewish community.

Valerie built her professional life from this passion and most recently founded her own firm -redVERED Nonprofit Strategies and Solutions – providing Jewish nonprofits expertise in strategic planning, resource development, programing and events, and organizational capacity building. Among other projects, she directed a $23 million capital campaign for Chabad NP | Chai Preschool and partnered with the Oshman Family JCC to produce the content and logistics for the Zionism 3.0 (Z3) Conference. Previously, Valerie was the West Coast Vice President of the Shalom Hartman Institute and led the Pacific Northwest Region for the American Israel Public Affairs Committee (AIPAC) – as its Regional Deputy Director and Interim Regional Director. Valerie has also managed to merge her commitment to Jewish values with another passion of hers, travel and adventure, by receiving fellowships from American Jewish World Service (AJWS) with which she spent a summer in rural Zimbabwe and a year in Mumbai, India serving local NGOs. She received her Master of Public Administration from the University of Southern California; graduated from Columbia University with a B.A. in Middle Eastern Studies; and studied at Tel Aviv University and University of Haifa.

Valerie and her husband Zack are the proud parents of their four spunky and precocious daughters: Siona (First Grade), Perri (Kindergarten), Edyn (Kindergarten) and Noa (future Hausner student).
