In 1977, the
Ohr Somayach yeshiva in
Jerusalem, Israel established an American campus in
Yonkers, New York. After two years, Rabbi Ezriel Tauber together with a group of lay leaders purchased land in
Monsey, New York to service a full-time Judaic learning center.{{cite book Monsey was chosen because of its proximity to
New York City (approximately northwest of the city) as well as the Jewish local infrastructure that ensured easy availability of kosher food and amenities. They maintained the name Ohr Somayach and enlisted Rabbi Israel Rokowsky as dean.{{cite web |website=hamodia.com As of 2019, Ohr Somayach has ceased operating as a yeshiva. However, under the leadership of Ohr Somayach alumnus Rabbi Yosef Simon, and under the guidance of some of the former leadership of Ohr Somayach, a new organization called Toras Dovid now operates a yeshiva for
ba'alei tshuva, as well as a kollel for ba'alei tshuva. ==Administration==
