Leadership and Administration


Sara Berk

Director of K-12 Learning and Inclusion 

Pronouns: She/Her


All children can succeed when they are provided with the right tools and support, which is why I love working at Temple Beth Shalom! TBS is a place where curriculum and support are provided in a way that allows each child to be successful. 


As the Director of K-12 Learning and Inclusion, I collaborate with Jewish Learning Guides (JLGs) and families to ensure that all children can successfully access the curriculum. I provide training for the K-12 faculty in order to support each child and teen in the Mayim and Etzim learning programs.


Prior to joining the team at TBS in 2013, I worked as a special educator in MA and NYC. I am a Board Certified Behavior Analyst (BCBA) and have a Masters Degree in Special Education. In January 2021, I founded Sara's Joyful Baking, which allows me to combine my love of teaching with baking.


Julia Zinn

Associate Director of K-12 Engagement 

Pronouns: She/Her

As an educator, I do my best to get to know each child and allow them to learn and grow in their own way. I believe in meeting children where they are and giving them the tools and support that they need to thrive. I am constantly impressed by the creativity and curiosity children share when presented with the proper environment and something to sparks their interest. I am incredibly passionate about Judaism, and it brings me immense joy to share that with my students and see them excited about being Jewish.

I first started working at TBS in November 2016, and am so thrilled to be able to continue my journey here. I grew up with a family of Jewish professionals in Worcester, MA and have a degree in Psychology and minors in Judaic Studies and Theater from the University of Delaware. I have spent the past 10 years working in Synagogues and Jewish Camps, focusing on Jewish Life, Education and General Programming. I currently live in Chestnut Hill with my dog, Madeline, and enjoy crafting, cooking, and spending time with my family and friends.


Liron Riess

Director of Mayim Tamid

Pronouns: She/Her


After years of teaching a variety of ages at TBS, I embraced the opportunity to pioneer the Mayim Tamid Program in 2016. Influenced by my early experiences growing up on a kibbutz in Israel, my goal for Mayim Tamid is to create a “Jewish home away from home:” a program that allows children to attend TBS multiple days a week, engage in deep Jewish learning, and enjoy additional recreational activities to support their health, growth, and emotional connection to Judaism and to our temple. An important value of Mayim Tamid is deep connection with parents and the rest of the family, so that we serve as a bridge between home and TBS. Another core value is each child’s comfort and sense of belonging, which I work with educators to cultivate. I live in Foxboro with my husband, and I am a mother of three grown children. I feel very fortunate to be a part of the TBS community and to keep developing an after school program that answers the needs of our families.
