Rabbi Zecharia Wallerstein ztl was the founder of Ohr Yitzchak, Ateres Naava Seminary for Girls, and Ohr Naava Women's Institute in Brooklyn, NY. Ohr Naava is a unique program designed for women ages 17 through 120 who are interested in furthering their Torah experience. The program, which was under the leadership of Rabbi Zachariah Wallerstein, started out as a Wednesday evening class in a small classroom known as a "Chabura." It brought together girls who had just returned from studying in Israel, college students who needed a weekly moment of inspiration, and most of all, Jews of different backgrounds with one common goal, to grow and change. The signature of Ohr Naava is to provide a multitude of programs, absolutely free of charge, for women wishing to make the time to grow, change and further their Torah knowledge.
