Our Clergy And Staff

Rabbi Micah Streiffer

Rabbi Micah Streiffer believes in thinking outside the box! Since he arrived at Kol Ami in 2011, the congregation has seen increased participation and engagement in the areas of music, learning, and ritual. From the classroom to the bima, from the board room to the hospital room, from “Sushi & Study” to “Rock & Roll Shabbat,” Rabbi Streiffer is excited to be part of this thriving community.

A skilled teacher and a gifted speaker, Rabbi Streiffer is known for his informal and approachable style on the bima and in the classroom, and for making Judaism accessible and meaningful for people of all ages and backgrounds. His rabbinate is guided by the principles of Lifelong Learning, Inclusiveness, and Tikkun Olam (Repairing the World). Since arriving at Kol Ami, he has worked to build or revitalize the congregation's activities in a number of areas, including worship, learning, Chesed ("caring community"), and interfaith connections. He serves as an active member of the Reform Rabbis of Greater Toronto.

Rabbi Streiffer grew up in south Louisiana, and was ordained a rabbi in 2007 at the Cincinnati campus of the Hebrew Union College-Jewish Institute of Religion. He served previously as Associate Rabbi of Temple Beth El in Charlotte, North Carolina, and has spent extensive time as an educator, musician, and rabbinical faculty member at a number of Jewish summer camps. He is active in the Reform Movement, having participated in a number of committees and boards at the local, national, and international levels. He is a corresponding member of the CCAR Responsa Committee, which deliberates on matters of Jewish law for the Reform Movement.
In addition to the bima, look for him at the guitar store, the sushi bar, the CrossFit gym, or cheering on the Blue Jays. He is the proud father of three sons (only one of whom is taller than he is, as of this writing).

He has actively pursued his passion for music as the lead of the "Arbah B'shir" Barbershop Quartet, and as a member of the Toronto Jewish Chorus and the Kol Neshama Choir.  Throughout his life, it has been the combination of music and community that have forged his strong connection to Judaism.

 Judy Silver
 Director of Education

    After 11 years in Minnesota, Judy returned to her childhood home of Toronto, where her passion for Jewish     education first took root and flourished, through family involvement in synagogue life, NFTY-NEL (aka NELFTY!),   and more than a decade at URJ Goldman Union Camp Institute in Zionsville Indiana.

 Judy’s philosophy of education is simple: to create memorable, relevant, fun, and engaging educational   experiences, accessible by all learners, and all styles of learning. Judy began her academic career at the University of Toronto, intending to become an archeologist. After travelling to Israel she turned her focus to Jewish education, and continued her studies in Jerusalem and Tel Aviv. She then received a B.A. and B.Ed. in Judaic Studies from York University (with a minor in Anthropology, to put all that Archeology study to good use!). Judy went back to school in 2015 at Hebrew Union College to obtain her Masters Degree in Religious Education and to complete her Reform Jewish Educators certification in 2017. She is starting her 8th year as Kol Ami’s Director of Education.

Judy’s professional career includes 11 years as a teacher at Bialik Hebrew Day School, 15+ years as a supplementary school teacher at synagogues in Toronto and Minneapolis, and 5 years as Director of Education at Shir Tikvah Congregation in Minneapolis. While at Shir Tikvah, she created a professional development program for school staff, revitalized post-b’nei mitzvah participation in the school, and partnered with a community service organization to champion and implement an inclusion program for all special needs students at the school. Judy served as chair of the Jewish Educators of Minnesota, on faculty at URJ camps GUCI, OSRUI and Camp George, and is a member of National Association of Temple Educators and The Ontario College of Teachers. She is currently entering her second year as chair of the Reform Educators Council in the GTA.

When she’s not creating curricula and developing new educational programs, she can be found Israeli dancing, decorating cakes, shopping for something new for her “Peanuts” collection, singing with her husband and just hanging out with her kids. An always optimistic Blue Jays fan, she can also be found yelling at the TV during the baseball season. She married Ian Silver at GUCI and they have three amazing kids, Toby, Sharon and Jeremiah.
