O Or Mel B Br theSara Shapiro-Plevan, EdD
Sara Shapiro-Plevan, EdD, is all about relationships: Her essential focus: understanding how human connection influences our ability to seek wholeness and strive for equity as we create sustainable networks, communities and workplaces.
As the founder and CEO of the Gender Equity in Hiring Project, Sara put Jewish values of equity and justice into action to build workplaces that reflect the best of our human potential—transforming pervasive cultures of bias that too often prevent women and people of all genders from advancing into leadership. Drawing on her extensive experience as a consultant, coach, facilitator, and educator, Sara has invested her career in exploring how gender, power, and privilege shape the Jewish professional landscape. A member of Cohort 3 of the Collective, Sara is a product of Elluminate’s investment in feminist leadership.
Sara holds an EdD and an MA from the Davidson School of The Jewish Theological Seminary, a BA from Brandies University, and was Senior Educator at the Melton Center at Hebrew University. She is a Certified Salary Negotiation Specialist and an Advanced Career Facilitator for the 21st Century, Equitable Compensation Certification, and holds DEI in the Workplace Certification from MUMA School of Business at the University of South Florida. In addition, she is an ICF certified Organization and Relationship Systems Coach. Sara serves as a board member of Camp Ramah New England and American University Hillel.
While not originally from New York City, Sara has made the urban jungle home for most of her life, loves wearing lots of black and living in an apartment. Her favorite ways to share time with others typically involve bringing people together for meals and sharing conversation over coffee. If she is not busy organizing people, she’s likely reading a book (ask for a recommendation) or looking for the closest bookstore. She proudly uses sports metaphors in her work (mostly incorrectly), thanks to her son, who teaches her about gender equity every day.
