Rabbi Chaim Dovid Zwiebel is the executive vice president of Agudas Yisrael of America. His relationship with the organization began while he was still a teenager, when he led Shabbos Pirchei groups on the West Side. Later, he was asked to write for the Zeirei Forum, an Agudah-sponsored publication for younger readers. A gifted writer, he was soon appointed editor. After working for many years as a lawyer at Paul, Weiss, Rifkind, Wharton, & Garrison, he was selected for his current position in 2008, after the passing of Rabbi Moshe Sherer.
