Tucker.Rabbi_0146_TouchedUp500pxRabbi Gordon Tucker has been at Temple Israel Center since 1994. In 2003, he was named Senior Rabbi.

A native of New York City, he holds the A.B. degree from Harvard University and a Ph.D. (in Philosophy) from Princeton University. He was ordained a Rabbi in 1975 by The Jewish Theological Seminary of America (JTSA).

Since coming to Temple Israel Center, Rabbi Tucker has worked to strengthen three primary areas of Jewish life: education for all ages, the spirituality of worship, and the obligation to reach out to the less fortunate.

Rabbi Tucker joined the faculty of JTSA in 1976 and has taught there continuously ever since. He is currently Adjunct Assistant Professor of Jewish Philosophy. From 1984 to 1992, he was Dean of the Rabbinical School at JTSA, in which capacity he directed the training of over 200 rabbis.

He is Honorary Chairman (and former Chairman) of the Board of the Masorti Foundation for Conservative Judaism in Israel, and served on the Committee on Jewish Law and Standards of the Rabbinical Assembly from 1982 to 2007.

While on a leave of absence from JTSA beginning in 1979, Rabbi Tucker served as a White House Fellow in the office of United States Attorney General Benjamin R. Civiletti.

Rabbi Tucker is the author of numerous articles on a wide range of subjects in Jewish thought, and most recently published a translation with commentary (entitled "Heavenly Torah") on Rabbi Abraham Joshua Heschel's major three-volume Hebrew work on rabbinic theology.

Cantor George Mordecai weaves his rich cultural heritage into his work as a performer and cantor. Born in Sydney, Australia to Iraqi and Indian Jewish immigrants, he was immersed from an early age in the musical and liturgical traditions of his family.He went on to help lead services at the Sephardic Synagogue in Sydney and appeared at various multicultural music festivals around Australia. George also sang with the Renaissance Players, a renowned and innovative early music ensemble based at Sydney University, and with the Capella Floriani, a musical and theatrical company devoted to a spiritual vision of the performing arts.

He received his Cantorial investiture and master’s degree in sacred music from the Jewish Theological Seminary in 2000. He has worked as a cantor in Sydney, Philadelphia, Miami, Stamford and is currently the Cantor at Temple Israel Center in White Plains, New York. George has performed Jewish liturgical repertoire in concert halls and synagogues in England, Paris, Israel, and various cities around the U.S. He has also performed in interfaith settings with Middle Eastern, Indian and African American musicians. In 2007 he met Patrick Quigley, artistic director of the world renowned choral ensemble Seraphic Fire, and together they developed a performance project, Shalom/Pax, which drew from the rich motivic and melismatic textures of the Gregorian and Jewish musical traditions.

George has devoted his life to pursuing a vision of devotional music that speaks to the sacred interconnectedness of all humanity and continues to work on projects that support this vision.

Mendelson.Cantor_0220_TouchedUp500pxCantor Mendelson has been at Temple Israel Center for over 25 years, enriching our community with his beautiful Hazzanut. He teaches many of the B'nai Mitzvah, gives courses in adult education, teaches in the middle school and is always available for private tutoring to any congregant who would like to learn to read Torah or lead the congregation in prayer.

Growing up in Brooklyn, New York, he witnessed the dwindling days of the Golden Age of Hazzanut. Now, as both an international performer and one of the leading cantorial masters of today, he is passing on his art to a new generation of cantors. For over 25 years he has taught at the Hebrew Union College School of Sacred Music, and the H.L. Miller Cantorial School at the Jewish Theological Seminary. Cantor Mendelson has the unique honor of receiving honorary doctorates from the Jewish Theological Seminary and Hebrew Union College.

Cantor Mendelson is a graduate of the Hebrew Union College School of Sacred Music and the American Opera Center at the Juilliard School. He is the composer of Weekday Mincha and Maariv and Improvisations on Shabbat Shacharit published by the Cantors Assembly, the organization in which he served as president in 2003 and 2004.

Recently he created the role of Shabtai Tz'vi in the world premiere of Richard Teitelbaum's Scenes From Tz'vi held at both Bard College and La Biennale in Venice. After a Carnegie Hall concert, the New York Times raved: "Mendelson's performance was magical....emotionally unguarded." In January 2006, he sang the memorial prayer at the United Nations General Assembly, on the occasion of the first international day to Commemorate Victims of the Holocaust.

Cantor Mendelson's discography includes Cantorial Recitatives by Legendary Masters, The Birthday of the World Part I and Part II, A Taste of Eternity, narrated by Leonard Nimoy, Jewish Music and More, recorded with his wife, cantor Fredda Mendelson, Hazonos, called "...jazz album of the year" by Wired Magazine, recorded with Frank London and his son, Daniel Mendelson, and most recently, Further definitions of the Days of Awe, with the Afro Semitic Experience, also featuring his son Daniel.
