Clergy : The Rabbis and Cantor of Temple Sinai

Temple Sinai has two full time rabbis (Rabbi Andrew Straus & Rabbi Jacqueline Mates-Muchin), and one cantor (Cantor Ilene Keys).  We are blessed to have such spiritual and visionary leaders enrich our congregational life.

To learn more about them, please see below:


Rabbi Andrew Straus

Rabbi Straus headshot Rabbi Andrew Straus brings a wealth of experience and enthusiasm to Temple Sinai. Emphasizing the importance of Jewish education for both young and old both in formal and informal settings, Rabbi Straus has a personal goal of increasing each congregant's love, understanding, and involvement in Judaism as a part of our daily lives. He believes that we have a responsibility to speak out from a Jewish perspective and act to address social justice and other issues in the broader community. He sees himself as a counselor, a shoulder and an ear for congregants, sharing our times of pain and sorrow, joy and celebration.

Rabbi Straus joins Temple Sinai along with his wife Karen and three children. Prior to this position, he served for 13 years as the spiritual leader of Temple Emanuel of Tempe, AZ. He has also served at Peninsula Temple Sholom of Burlingame, CA and Temple Beth Sholom of New City, NY. He received his Rabbinic Ordination from Hebrew Union College – Jewish Institute of Religion in Cincinnati, Ohio. Raised in a liberal, conservative congregation in Poughkeepsie, NY, he gained an understanding of and an appreciation for both traditional and contemporary Judaism – two forces he believes must be blended for Judaism to flourish.

Rabbi Straus is very pleased and excited to be joining the Temple Sinai family, continuing our rich traditions while leading Temple Sinai into the future. He looks forward to sharing his enthusiasm and love of Judaism, learning along with us, and inspiring each of us to do mitzvot and walking the path of life according the values, morals, and customs of our ever new Jewish civilization.

She also received awards for pastoral excellence and for excellence in service of a congregation by a rabbinic intern.

After graduating from Lowell High School in San Francisco, Rabbi Mates-Muchin attended the University of California at Santa Barbara where she double majored in Religious Studies and Cultural Anthropology. She graduated in 1997 with high honors and as a member Phi Beta Kappa. At UCSB, she met her husband, Jonathan, to whom she has been married since 1997. Together, they have four children.
