Alex Peskin, senior at Block Yeshiva High School, addresses the audience during a siyum — a celebration of a completion of study on a sacred text — at H.F. Epstein Hebrew Academy. Next to Peskin is a photograph of the late Rabbi Sholom Rivkin and his wife, the late Rebbetzin Paula Rivkin. Four Orthodox day schools came together for the program in tribute of Rabbi Rivkin, who died  on Oct. 1.
