Gavin Marx has been a member of Kehillat Masada since 1986 and he joined the board in 2018. He has been involved in developing the Bar and Bat Mitzvah Program and various other initiatives.

Gavin is a Medical Oncologist. He is the Clinical Director of the San Integrated Cancer Centre and the San Clinical Trials Unit at the Sydney Adventist Hospital.

He is passionate about Jewish continuity and loves living on the North Shore with its wonderful community. His many highlights at Kehillat Masada include his wedding, his son’s Bar Mitzvah and his son’s Brit Milah on second day Rosh Hashanah shared with the whole community. He is married to Jo and they are so proud of their two children Tali and Josh.


Yair Miller OAM  has been on the board for over 15 years. Yair is CEO of UIA Australia and past President of the NSW Jewish Board of Deputies. He loves the incredible community feeling at Kehillat Masada and the unique way all ages and demographics blend and are able to feel at home.   Yair is married to Sandra  and is blessing with 2 children, Ariella and Josh.


Dave became a member of Kehillat Masada in 1988 and joined the Board in 2017. He was appointed  Hon. Secretary in 2019.

He manages KM Cares, the benevolent fund and Chesed arm of the Kehillah which is dedicated to support those in need in our community.

Dave runs his business which manufactures and supplies customised apparel for sports clubs, schools and corporations. He is a very hands-on grandfather to  his four grandchildren. He loves how welcoming this community is and how it always steps up in times of need. He is also a passionate Rugby Union supporter and an enthusiastic  golfer.


David Sandler became the Treasurer at Kehillat Masada in 2023. David joined the shul in 2012 after moving to Sydney from London (with a few years in Johannesburg along the way). He is also the Treasurer at Bank of America in Sydney.

David represents Kehillat Masada as a constituent deputy at the NSW Board of Deputies and is on the Executive of the Council of Orthodox Synagogues (NSW). He also leads Community Health Support’s efforts on the North Shore and is a Board member at Kesser Torah College.

David is married to Jenna and has four children – Zach, Maya, Noa and Benji.


A founding member and past-President of Kehillat Masada, David feels a deep sense of pride at the growth and development of our Kehillah. From humble beginnings in the early 1990s in people’s homes, to the dynamic and robust organisation it is today. David has a love of Judaism and all things Jewish. His belief in the benefits of a Jewish education plus his passion for Israel are the essence of his Judaic-DNA.

Married to his lifelong best friend, Ros, they have three wonderful children and two precious grandchildren.

David’s current focus is the Kehillat Masada bequest initiative. It seeks to identify members who love the community and feel a connection, who care about its stability and future and feel a responsibility to give back. The aim is for Kehillat Masada to be included as a beneficiary in one’s will, no matter the amount or how old a person is.

David’s plan is to connect with people over the coming months to roll out this initiative and give each member this legacy opportunity.

She’s originally Canadian and her favourite chag is Pesach.
