In 2004, Klapper left Harvard Hillel to launch the Center for Modern Torah Leadership, which is a registered non-profit which describes itself as "the intellectual catalyst of Modern Orthodoxy" and aims "to make halakhah the shared spiritual language of the Jewish community, and to make Jewish discourse an essential contributor to the moral conversation of humanity." The center took over the annual Summer Beit Midrash fellowship program and launched the Winter Beit Midrash, an shorter three-day program for students during winter break, and Midreshet Avigayl, a high-level Talmud program for teenage girls. The center also holds national conferences on halakha for select groups of Orthodox rabbis and educators."CMTL holds national conference."
