    Jeremy Kalmanofsky arrived at Ansche Chesed in 2001 and has never looked back. He loves working here because, he says, despite all the prophecies of gloom about American Judaism, the Ansche Chesed community proves that traditional but heterodox Judaism can thrive.

    For Rabbi Kalmanofsky, being a congregational rabbi is the perfect job. "I spend my days performing mitzvot (commandments)—praying, studying, doing acts of tzedakah (charity) and chesed (kindness), performing rituals, and helping people," he says. "What could be better?" He is especially gratified by the time he spends one-on-one with congregants, hearing what inspires them, what they believe in and hope for, what troubles them, and what keeps them going during difficult times. He is grateful to Ansche Chesed's members for inviting him to share their joys and sorrows, from births to deaths.

    Rabbi Kalmanofsky was ordained in 1997 by The Jewish Theological Seminary of America, where he was a Wexner Graduate Fellow. He regularly publishes essays on Jewish thought and practice, and he serves on the Conservative movement's Committee on Jewish Law and Standards.

Miller Cantorial School and Hebrew Union College’s Debbie Friedman School of Sacred Music. The founding conductor of two Jewish community choruses, Shir Chadash in Brooklyn and Ansche Chesed's Shirei Chesed, Hazzan Hirschhorn is also Vice President of Shalshelet: The Foundation for New Jewish Liturgical Music.

    Dedicated to sharing her enthusiasm and musical knowledge with her former compatriots, whom she taught as music director of the Kiev Jewish Youth Music Theater “Yehudim” until 1992, when she came to the U.S., Hazzan Hirschhorn has taught classes on Russian-Jewish culture at the North American Jewish Choral Festival, the Havurah Institute, both the British and New York Limmud conferences, and at programs presented by COJECO (Council of Jewish Émigré Community Organizations), the central coordinating body of New York's Russian-speaking Jewish community. Through a UJA-Federation Synagogue Outreach Network grant, she developed a program for unaffiliated Russian-speaking Jewish families, which she offered at Ansche Chesed.

    A native of Ukraine, Hazzan Hirschhorn studied musicology, piano and composition in the honors program at Moscow Gnesins’ Musical College and at the Kiev State Conservatory. She feels extremely fortunate to live in a country where she can freely indulge her passion for Judaism, Jewish music and educational outreach.

Her childhood play has become her professional passion as she now works to help others feel as comfortable and welcome in synagogue as she has always felt.

    Ordained by The Jewish Theological Seminary of America, Rabbi Hammerman also received a degree from its Davidson Graduate School of Jewish Education. Before joining Ansche Chesed, she was a student rabbi at Congregation Eitz Chaim in Monroe, NY, and Director of Student Placement at The Jewish Theological Seminary's rabbinical and cantorial schools.

      Excited about being a part of the AC community, Mark got involved on committees soon after joining. He has served on the Sanctuary Service, Membership, and Tribute committees. Prior to being elected President, Mark served on the Board of Trustees and three years as Secretary. Mark is inspired by the wonderful people he has met and friends he has made at Ansche Chesed. He aspires to have an exciting, joyful congregation with diverse offerings for our community to come together in prayer, learning, celebration, and play.
