Our Rabbeim

Yeshivas Chosein Yehoshua's primary offering is its stellar lineup of Maggidei Shiur and Shoel Umeishivim. Accomplished talmidei chachamim and exemplars of the way of the Torah, these Rabbeim teach, guide and love our talmidim, giving them rock-solid foundations for their learning careers and the remainder of their lives. The Rosh Yeshiva's generous leadership style allows each of the Rabbeim space to use their diverse personalities to transmit to the next generation of Torah.
