Jayson Taller - Executive Director 

Jayson has been a member of the Machzikei community his entire life. He even had his Bar Mitzvah at Machzikei! 

In the years since those days as a kid around Machzikei, he went on to study at Carleton University, earning his B.A. in Political Science and has completed the Canadian Securities Course.  For eight years, he worked in the financial services industry, working as a financial advisor with two of Canada’s largest financial institutions.

Jayson is thrilled to be back to his roots at Machzikei, and to be working with the CMH community to build a thriving kehila in the Nation's Capital.

Feel free to contact Jayson anytime at the shul office at 613-521-9700 or via email at

Dr. Stacy Goldstein - Director of Community Building

Growing up in Toronto, Stacy never imagined she would end up living in the Nation's Capital, and now she can't imagine living anywhere else. Fortunately for Machzikei, life led Stacy to Ottawa, and she has embraced this community with joy and enthusiasm.

A practicing chiropractor, mother, distance runner, and master challah baker, Stacy has a contagious energy and enthusiasm for everything that she does. From 2010-2015, she was the co-founder and co-director of the Glebe Shul, an outreach program in Ottawa with a community of over 750 Jewish young adults.

Stacy's role as Director of Community Building has her overseeing the Shabbat and Yom Tov youth programs, monthly family events (such as Shabbat dinners and holiday parties), and outreach with families who are new to the Machzikei community.

Please feel free to contact Stacy anytime at 613.618.1235, or

Sari Zelenietz - Youth Programming Coordinator

Sari grew up in Halifax, Nova Scotia, and her first job was teaching the preschool Hebrew School class at her synagogue. She’s excited to return to her roots in Jewish Community life working with children and families at Machzikei.

A genetic counsellor by day, Sari is an active member of CMH, and has served on the board and multiple committees. She is a board member and volunteer with Ten Yad and JET Ottawa. Sari and her family love life in Alta Vista and can be found enjoying one of the neighbourhood’s beautiful parks almost every Shabbos afternoon.
