|Molly Roston||Rabbi Heath
Congregation Beth Am is served by an outstanding clergy and programming staff. Rabbi Janet Marder, who has been with Beth Am since 1999, is the fourth senior rabbi in the history of Beth Am. She sets a tone of warmth and inclusiveness that permeates this dynamic staff. Our staff come from a variety of Jewish backgrounds and reflect the wonderful diversity that is characteristic of this community.
Rabbi Janet Ross Marder, Senior Rabbi
Rabbi Janet Marder, a Los Angeles native, graduated from the University of California at Santa Cruz and was ordained in 1979 by the Hebrew Union College-Jewish Institute of Religion in New York. Following ordination, she pursued graduate studies in the Department of Comparative Literature at UCLA, specializing in Modern Hebrew and Yiddish.
In 1983, she became the first ordained rabbi of Beth Chayim Chadashim, a Los Angeles synagogue with special outreach to lesbian and gay Jews. During her five years with that congregation, she founded NECHAMA, a Federation-funded program of AIDS education for the Jewish community. From 1988 to 1999, Rabbi Marder served the Union of American Hebrew Congregations (now the URJ), providing leadership and guidance to Reform synagogues in Southern California, Arizona, New Mexico, Nevada and Texas.
In August 1999, she became Senior Rabbi of Congregation Beth Am. In her Vision for the Congregation, presented in April 2009, she said, “I want us to be a congregation that is Jewishly dynamic, focused on moving every member forward from where they are right now. Imagine a synagogue in which you’re always looking for ways to climb up to the next step; progressing towards deeper learning, richer faith and spiritual development, greater commitment and practice. In this place, we’re ambitious for our own growth; we’ve tasted something delicious and we’re always hungry for the next bite. Our Judaism is not fueled by habit, guilt or fear of anti-Semitism; we’re drawn forward by love and joy, motivated by curiosity and the search for meaning. We know that new discoveries will unfold every year of our life; we’re excited about making this lifelong journey with good companions who will be with us all the way.”
Rabbi Janet Marder's articles have appeared in Reform Judaism Magazine, The Reconstructionist, Sh'ma and several anthologies. She has served as President of the Pacific Association of Reform Rabbis, the first woman and the first non-congregational rabbi to be elected to that office. In April 2003 Rabbi Marder was elected the first woman president of the Central Conference of American Rabbis. She is a Senior Rabbinic Fellow of the Shalom Hartman Institute in Jerusalem. Rabbi Marder and her husband, Rabbi Sheldon Marder, served as co-editors, translators, writers and commentators for two liturgical projects published by the Reform Movement: Mishkan HaNefesh: Machzor for the Days of Awe, and Mishkan HaLev: Prayers for S'lichot and the Month of Elul (CCAR, 2015 and 2017).
