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.

Natasha Hirschhorn is happy to have found her spiritual and professional home at Ansche Chesed, whose staff she joined in 2004. Her multifaceted role includes helping to lead services, coaching members who wish to learn how to be prayer leaders or Torah readers, and directing Ansche Chesed's Shirei Chesed Community Chorus.
An accomplished singer, pianist and composer, Hazzan Hirschhorn has performed at the Toronto Jewish Music Festival, the North American Jewish Choral Festival, the Kennedy Center, Lincoln Center, Strathmore, New York University, Indiana University and Drexel University, and at venues in the U.S. and Canada.

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.

Rabbi Hammerman loves creating dynamic Jewish learning experiences for students of all ages, from toddlers to older adults. She is committed to helping to build a warm, strong and engaged Jewish community at Ansche Chesed.
Rabbi Hammerman was born and raised in Toms River, NJ, and from a young age she felt at home in synagogue and could often be found “teaching” and “leading” her real and imaginary friends. 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. She has held positions at B’nai Jeshurun; the Forest Hills Jewish Center; St. Luke’s Hospital, where she served as a chaplain; and the Solomon Schechter School of Manhattan.
Rabbi Hammerman lives on the Upper West Side with her husband, Rabbi Josh Rabin, and their children, Hannah, Shai and Ella.
