Howard M. Holtzmann Jewish Chaplain at Yale

Rabbi Jason Rubenstein

Jason Rubenstein comes to Slifka Center from a background as diverse as Yale’s Jewish community: a childhood at Temple Micah in Washington DC, formative years studying at Yeshivat Ma’ale Gilboa in northern Israel, and rabbinic ordination at the Jewish Theological Seminary. For the past eight years Jason has taught on the faculty of the Hadar Institute, where he’s created classrooms, conversations, and communities that bring Torah to life by drawing on the fullness of students’ lives.

From his own formative undergraduate years at Harvard Hillel, Jason personally knows the value of Slifka Center’s work. Creating a community of meaning where students forge identities as Jewish leaders and relationships with one another that will continue to grow and deepen even after graduation not only enriches the lives of individual alumni – it has the potential to reshape and enliven the American Jewish landscape through those alumni’s talents and contributions.

In addition to rabbinic ordination, Jason holds an AB in Social Studies from Harvard College and a Masters in Talmud from JTS. He is also the recipient of numerous awards including the Wexner Graduate Fellowship and the Covenant Foundation’s 2015 Pomegranate Prize for Emerging Educators.

Jason and his wife, Arielle, are grateful to be raising their two sons in beautiful East Rock, as members of the gracious and brilliant Yale Jewish community.

Rabbi Alex Ozar grew up in St. Louis, MO. A fourth generation Missourian on both sides, he left home to spend two blissful years studying in Israel at Yeshivat Kerem B’Yavneh and then returned stateside to attend Yeshiva University, where he received his BA, MA and Semikha. A proud Bulldog himself, Alex is now pursuing his PhD at Yale in Philosophy and Religion, with a focus on prophetic witness and the how-to’s of pursuing justice in an often-indifferent world. He is especially excited that I-95 will no longer feature in his daily commute. Alex has worked for First Things magazine, as a Tikvah Fellow, and as a gemara teacher at Bi-Cultural Day School in Stamford, CT.

Jewish Agency Israel Fellow

Keren Almaz Marsha

Before I became an Israel Fellow I worked at a hi-tech company as a Human Resources Coordinator. After I finished my M.A, I decided to do something more meaningful for myself and other people. Since I’m coming from the beta Israel community and a Zionist family, one of my goals is to share my story and my point of view about Israel. As an optimistic person, I’m hopeful that I can share my enthusiasm for how great Israel is.

Over my tenure at Hillel at Kent State, I gained vast insight into American culture at Kent and spread Israel knowledge to hundreds of ambitious students. Through multiple programs, I was able to successfully share insights into Israeli culture, politics, and ideas – not only Israel but also the beta Israel nation and movement.

I helped re-found a program at Kent Hillel called Golden Flashes for Israel filled with multiple passionate students. Together, we inspired students to appreciate and understand Israel more. I’m very proud of the projects we did and its successes especially since students and staff still bring it up months later how it impacted them to research more about it and my story.

I am excited to join the Slifka Center community at Yale this Fall!
