Rabbi Miriam Philips - JCAL Director

Rabbi Miriam Philips enjoys serving as the Director of Youth Education and Family Engagement (also known as the JCAL Director) for Temple Bat Yahm. JCAL, the Jewish Center for Arts and Learning, encapsulates Rabbi Miriam’s learning philosophy: that children learn best in community and through doing. After all, the world - and Judaism - stand on three things: Torah (love of learning and questioning), Avodah (service to God) and G’milut Chasadim (acts of loving kindness). In Judaism, learning and doing are intertwined.

Rabbi Philips grew up in rural Washington State, where her family had to work to be Jewish, and so started her on her path toward the rabbinate. She also spent part of her childhood in  Seal Beach, CA, from which Orange County town her husband Danny also hails. Rabbi Philips attended Brandeis University, where she graduated summa cum laude with a major in History. After college, Rabbi Miriam volunteered in Israel for a year with Project Otzma (sponsored by the Long Beach Federation) and worked for congregations in the San Francisco Bay Area. For rabbinical school, she attended Hebrew Union College-Jewish Institute of Religion (HUC) in Jerusalem and LA. While there she earned her Master’s degree in Education.

Before joining Temple Bat Yahm, Rabbi Philips served as the Director of Lifelong Learning at Temple Emanuel in Andover, MA, for four years. Then she and her family moved to Silicon Valley so she could take a position as Director of Family Learning at Congregation Beth Am in Los Altos Hills, CA. Rabbi Miriam and her family now consider themselves home in Orange County and at Temple Bat Yahm.

Rabbi Miriam is the proud (and busy) mom of two children. In her free time, she enjoys hiking, gardening, reading and dancing, which have now become family activities. Her blessing for her children is her same wish for all the children (and human beings) at TBY: may you be curious and kind.

Cantor Elisa Waltzman - Associate Cantor

Cantor Waltzman is a member of the American Conference of Cantors. She was ordained by the Academy for Jewish Religion in 2009, after earning both her Master of Music and Bachelor of Music Degrees in Vocal Arts from the University of Southern California.

She also studied at the Manhattan School of Music in New York, and has performed at various internationally recognized Music Festivals including three years at the Music Academy of the West, where she studied with acclaimed mezzo-soprano, Marilyn Horne. Additionally, Cantor Waltzman is a graduate of the Orange County School of the Arts Musical Theater Conservatory.

Cantor Waltzman’s childhood was filled with Jewish music sung by her late grandfather, Rabbi Cantor David J. Kane- a Holocaust survivor whose vocal talent as a child secured him a space in a concentration camp children’s choir, ultimately saving him from the gas chambers.

Inspired by her grandfather’s immense passion and deep joy of singing, Cantor Waltzman began her formal vocal training at the age of eleven, and regularly sang cantorial music and liturgy with her grandfather at Temple.

Blending her background, love of various musical styles, knowledge of Hebrew song repertoire, and the musical sounds and styles most enjoyed by her own young children, she released her first studio album Reinvented-Hebrew Songs for Families in 2015.

Formerly a freelance Cantor, she has over ten years of experience working with a wide range of clergy and different congregations.

Her connection to TBY began in 2007, when she was a cantorial student. At that time she was living in Irvine with her husband while he attended medical school at UC Irvine. Cantor Grant hired her as a B’nai Mitzvah instructor, and became a significant mentor.

For the past few years Cantor Grant graciously welcomed Cantor Waltzman to TBY regularly as his substitute, where she had the privilege of leading services with our inspiring Rabbis, and enjoyed meeting the wonderful TBY community.

She is a California native, after living in various parts of the country, Cantor Waltzman is happy to be back singing under the California sun.

As part time clergy, Cantor Waltzman is delighted to have more opportunities to share her voice. She is grateful for TBY, where musical excellence, spirituality, and a welcoming nature are alive.

Along with her husband, Dr. Josh Waltzman, and three daughters, Cantor Waltzman is excited to be part of this community, and have the opportunity to contribute to the songful spirit of TBY!

Rabbi Mark S. Miller (z"l) - Rabbi Emeritus

Rabbi Miller served as spiritual leader of TBY for over 35 years, leading the congregation from its small and humble beginnings to its position as one of the premier Reform Jewish synagogues in Southern California. A distinguished scholar and educator, Rabbi Miller had been selected annually by the Daily Pilot newspaper as one of the most influential leaders in Orange County. He received his B.A. in Political Science from American University in Washington, D.C., his M.A. in Hebrew Letters, Rabbinic Ordination and Doctor of Divinity Degree from the Hebrew Union College in Cincinnati. He served for three years as Associate Rabbi of Temple Sinai in Roslyn Heights, N.Y.  He taught the sole Judaica course at U.C. Irvine for 22 years, taught the Senior Judaica course at Tarbut v’Torah Community Day School for two years, and taught Hebrew Scripture for 7 years at Chapman University. Rabbi Miller is in great demand as a speaker at community events and his column appears in the Daily Pilot newspaper.

Among the many world leaders he has attracted to address the congregation are Yitzchak Rabin, Henry Kissinger, Elie Wiesel, Shimon Peres, Benjamin Netanyahu and Ehud Barak.

Rabbi Miller has a long and illustrious history of contributions to the community and to Israel, serving in such positions as National Rabbinic Adviser to the Young Leadership Cabinet of the United Jewish Appeal; member of the Board of Governors of the College of Judea and Samaria; and President of the Orange County chapter of the Friends of the Israel Defense Forces. He has been a devoted supporter of Beit Mazor Home for Asthmatic Children in Arad, Israel, and works extensively on behalf of Bikkur Cholim Hospital in Jerusalem.  In addition, he has served as President of the Orange County Board of Rabbis and has led numerous leadership missions to Israel, several in association with the Hebrew University of Jerusalem.

An avid fan of the Chicago Cubs, Rabbi Miller delivered the invocation at the National Baseball Hall of Fame Induction Ceremony in Cooperstown, N.Y. in 2003. He has invoked G-d’s blessings in both the U.S. Senate and the House of Representatives in Washington, D.C.  Rabbi Miller is survived by his wife Wendy and their five children.​

“Over these decades, I have given my heart to this congregation and my heart has been touched on so many occasions, through so many experiences, and by so many people. From the vantage of such longevity with one congregation and community, I am now reaping the rewards of inter-generational sharing in the lives of families. I am naming the children of parents at whose naming ceremonies I once officiated, celebrating the B’nai Mitzvah of young people whose mothers and fathers heard my words of Torah when they themselves were called to the Torah, and I am joining in times of family sorrow as they grieve for members I have long known.  In joy and sadness, on the summit and in the valley, and in all the times and situations in between, together we are engaged in the pursuit of holiness and heritage, belief and learning.”

Rabbi Miller passed away on Thursday, April 5, 2018 after a 15 month battle with cancer. Through that time, he continued to write a weekly Torah Thought and engaged in the TBY community to his fullest ability. 

Zichrono Livracha, may the memory of our beloved Rabbi Miller ever be a blessing.
