Clergy: The Rabbis and Cantor of Temple Sinai

Temple Sinai has two, full-time rabbis, Rabbi Jacqueline Mates-Muchin and Rabbi Yoni Regev; 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 Jacqueline Mates-Muchin

Acting Senior Rabbi 

Rabbi Mates-Muchin PhotoRabbi Jacqueline Mates-Muchin joined the Temple Sinai community in 2005. She takes particular pride in Sinai's dedication to learning, inclusivity and social justice and feels blessed to be a part of such a dynamic and warm community.

Rabbi Mates-Muchin has been active in the leadership of East Bay Jewish life, currently serving as the president of the East Bay Council of Rabbis. She strongly believes in the importance of supporting and serving our greater community as well and works with the Oakland Fire Department as a volunteer chaplain amongst other civic and interfaith involvement.

Prior to her service at Temple Sinai, Rabbi Mates-Muchin served as the Assistant Rabbi in Buffalo, New York. She was ordained at Hebrew Union College-Jewish Institute of Religion in New York, having received awards for liturgy, history, bible, homiletics, religion and humanities. She also received awards for pastoral excellence and for excellence in service of a congregation. Her thesis entitled "The Analects of Confucius and Its Parallel in Early Rabbinic Thought"  was a reflection of her Chinese and Jewish traditions. She is the first Chinese American Rabbi.

Rabbi Mates-Muchin is a native of San Francisco and enjoys connecting with those who attended her alma matter, Lowell High School. She graduated from UC Santa Barbara with high honors and while in Santa Barbara met her husband, Jonathan. They live in Oakland with their four wonderful children.
