The two friends and Rabbi Zev Gold of the local Congregation Beth Jacob Anshe Sholom[1][2] formed a board and established the yeshiva on Keap Street in Williamsburg as an elementary school.

[6] After Mendlowitz died in 1948, rabbis Yaakov Kamenetzky and Refael Reuvain Grozovsky became roshei yeshiva.

[7] The yeshiva has since expanded to include a beit midrash in Monsey, an elementary school division in nearby Marine Park, and two summer camps.

[10] The three roshei yeshiva as of 2018 were rabbis Yisroel Reisman, Yosef Savitsky, and Yitzchok Lichtenstein.

[11] The previous roshei yeshiva include rabbis Shraga Feivel Mendlowitz, Yisroel Belsky, Avraham Yaakov Pam, Shlomo Heiman, Dovid Leibowitz, Yaakov Kamenetsky, Shachne Zohn, Zelik Epstein, Gedalia Schorr, Elya Chazan, Reuvain Fein, Simcha Sheps, Moshe Rosen (Nezer HaKodesh), and Reuvain Grozovsky.
