Encounter’s Executive Director

  • Yona Shem-Tov

    Yona Shem-Tov, Executive Director

    Yona joined the Encounter team as Executive Director in 2011.

    Before coming to Encounter, Yona pursued doctoral work at New York University as a Wexner Graduate Fellow, where her research focused on citi­zen­ship and history educa­tion in Jewish and Muslim-American schools. She has worked and consulted for a broad range of American Jewish orga­ni­za­tions, including American Jewish World Service, Mayan, Matan, RAVSAK, and Abraham’s Vision, where she taught at both the AJ Heschel School and the Al-Iman School in Queens, NY.

    As a consul­tant to the Edmond & Benjamin Rothschild Foundation, Yona helped envi­sion and launch The Ariane de Rothschild Fellowship, a network of Jewish and Muslim social entre­pre­neurs in France, the UK and USA. She also co-created Re/Presenting the Jewish Past, a network of Jewish history educa­tors from across Canada and the USA, where she served as Associate Director.

    She is a noted public speaker, having presented on Israel and inter­cul­tural educa­tion before The Congress of Imams & Rabbis in Seville, the German Consul General and members of German Parliament in Berlin. As someone who grew up in a home of “rich cultural complexity where Hebrew, Arabic, Polish and English inter­min­gled and seam­lessly inter­twined” — her mother survived the Holocaust as a child in Europe and her father was born in Iraq — Yona brings to Encounter an excep­tional capacity to guide and inspire commu­ni­ties to extend them­selves across lines of difference.

    As Yona herself noted recently: “Encounter is the orga­ni­za­tional embod­i­ment of my most deeply held values. I am deeply honored to grow the impact of one of the most effec­tive forces for creating inclu­sive and compelling Israel engage­ment strate­gies for the North American Jewish commu­nity and for helping to resolve the Israeli-Palestinian conflict”.

  • Rebecca Polivy

    Rebecca Polivy, Director of Programming

    Rebecca has exten­sive expe­ri­ence working in not for profit orga­ni­za­tions whose mission is to address the Israeli-Palestinian conflict and attempt to trans­form rela­tion­ships between different popu­la­tion groups. She has worked for Encounter for 4 years, serving as the Middle East Director before tran­si­tioning to her current role of Director of Programming. Rebecca began her career in Conflict Transformation in 2006 when she moved to Jerusalem. Prior to Encounter, she held posi­tions at The Abraham Fund Initiatives, Search for Common Ground, Breaking the Silence and Ultimate Peace. In these posi­tions she contributed to the design and imple­men­ta­tion of a number of programs that empha­sized sports, social entre­pre­neur­ship, print and tele­vi­sion media, as well as face to face inter­ac­tions as tools for trans­forming conflict. Out of a passion for the game, and recog­ni­tion of its unique contri­bu­tion to the field of peace building, Rebecca helped estab­lish the sport of Ultimate Frisbee in Israel and the West Bank by forming and leading a group of volun­teer trainers and coaching youth teams herself. Rebecca was a PresenTense Fellow in 2009, holds a Masters in Conflict Transformation and Intercultural Organizational Leadership from the School for International Training in Vermont, and a Bachelors in Comparative Religion and Economics from the University of Rochester.
