Yeshiva Rabbi Chaim Berlin
It is primarily an American, Lithuanian-style Talmudic Haredi Judaism but non-Hasidic yeshiva. It presently has an enrollment of close to two thousand students ranging from its elementary division to its post high school beit medrash and kollel (known as Kollel Gur Aryeh) divisions. Many of its graduates fill important positions in Orthodox educational institutions in the United States.
Its most famous rosh yeshiva (dean) was Rabbi Yitzchok Hutner (1906-1980) who was its head from 1936 until his passing in 1980. It has a branch in Jerusalem, also established by Rabbi Hutner, known as Yeshiva Pachad Yitzchok ("Fear of Isaac") named for Rabbi Hutner's books on Jewish Torah thought.
