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

Assistant 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 8 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



As an educator at TBS I am committed to creating an environment that welcomes each individual child with warmth, joy and a feeling of safety and acceptance. I provide structure, I encourage an interest in learning and I always look for ways to support each child in feeling successful, in a surrounding that meets all needs. I work tirelessly to connect with parents and sometimes with school so all are on the same plan for success. Family engagement and communication is essential in creating a home away from home in Mayim Tamid Shanah Alef.

During the year we will foster a sense of a family like, tight community, respect for each other and respect for all that’s around us, and we will focus on ways we can contribute to our world. Raised in Israel, I am passionate about sharing experiences and memories from my upbringing, and I find myself using content I remember enjoying as a child. I grew up on Kibbutz Ginnosar, right on Lake Kinneret. The Jewish education I received was centered on love for the land of Israel, the history of the people, and had a strong focus on celebrating the holidays and the traditions that kept Judaism alive all around the world for all these years.

I had gained incredible experience working with children at the Kibbutz, as well as teaching young women during my service at the Israeli Army, so when I arrived to the US over 20 years ago, I began working with children in a Children’s Center in Cambridge and then in Foxboro. My college courses focused on Child Psychology and Child development and added to my passion in continuing working with children at TBS. Here I found a warm community, that is open and inclusive. I feel fortunate to have been a part of developing and delivering the Mayim Education for KG/1st Grade, Kindergarten Enrichment on Fridays , Hebrew learning and Mayim Tamid.
