Rabbi Yoel Teitelbaum founded a network of large educational institutions, both yeshivas and girls' schools. If its schools in New York were a public school system, it would be the fourth-largest system in the state, after those of New York City, Buffalo, and Rochester. In most places, the girls' schools are called "Beis Rochel", and the yeshivas "Torah VeYirah". In 1953, Rabbi Teitelbaum founded the Central Rabbinical Congress of the United States and Canada, which provides various services, including a kashrut supervision.
