He completed an MA in Talmud and Rabbinics at the Jewish Theological Seminary in NY. During that time, he was honored as a Professor Saul Lieberman Graduate Fellow. He recently was awarded an honorary doctorate from JTS for 25 years of service in the pulpit.
Rabbi Kupchik has served congregations in Staten Island, St. Catherines, Ontario, Leonia, NJ and Peekskill and Brooklyn, NY. He has also filled educational leadership positions including at the Solomon Schechter High School of Buenos Aires, East Bergen NJ Regional High School and the Brandeis School in Lawrence.
