He also pioneered the establishment of community kollels in the United States and other countries. Unlike a kollel, which is a full-time learning program, a community kollel is a part-time learning program, part-time outreach program. Its Torah scholars learn together in the morning and afternoon and then interact with lay members of the community by offering evening lectures and one-on-one learning. Serving as a hub of Torah activity, community kollels make a significant impact on the growth of Torah awareness in remote Jewish areas. His able assistant in this endeavor was Rabbi Nosson Meir Wachtfogel (1910–1998), the Lakewood "mashgiach" (spiritual supervisor), who had been one of the original students of Rabbi Aharon Kotler when Beth Medrash Govoha first opened in 1943 and who subsequently served as "mashgiach" under three generations of "roshei yeshiva". Rabbis Kotler and Wachtfogel paved the way for the opening of community kollels in many cities, including Passaic, New Jersey (this kollel developed into the Yeshiva Gedola of Passaic), Chicago, Pittsburgh, Detroit, Los Angeles, Toronto, and Melbourne, Australia.
