Eli Levin
BOARD MEMBER

Sarah Dershowitz
BOARD MEMBER
Hi! I am Sarah, call me ‘Sarah/she/her’. I am ‘old Seattle’ without the ‘freeze’ – you are *actually* invited for Shabbat. I love babies, baking, Battlestar Galactica, and helping out with programming at Mercaz. I have one husband, one leopard gecko, three cats, five children, and ~12 chickens. When I work outside the home, I work in ‘computers’. As one of the ‘OG’ Mercazians, it is a delight to continue my service to Mercaz on the board as the token Dershowitz.

Sarah LaFreniere
BOARD MEMBER
Sarah grew up in Edmonton, Canada, and previously lived in Washington DC and Ottawa, Ontario. Sarah is committed to fostering Jewish engagement within the community and seeks to create meaningful connections among members and guests. Professionally, Sarah is an attorney representing claimants in private antitrust litigation matters. She has a passion for cooking and enjoys bringing people together through food, along with her husband and son. Sarah moved to Seattle in 2023 to be closer to family and the great outdoors; she is also passionate about skiing and hockey.

Zelle is currently the Director of Institutional Advancement at Northwest Yeshiva High School, her alma mater. She is excited to join the Mercaz Board to give back and support our growing community.
