Our people

A team of expert rabbinic inspectors

We employ a team of talented rabbinic inspectors who are experts in the intricacies of modern food production as well as the specifics of Jewish law. Our team works in conjunction with food manufacturers and foodservice establishments to ensure that food which is COR certified complies with the highest kosher dietary standards.

Our history

Seven decades of standard-setting

COR's roots trace back to a mid-century effort to bring order and consumer trust to kosher supervision. A committee of rabbis and community leaders came together in the early 1950s to set consistent standards, and in 1956 the organization took the name it still carries today: the Council of Orthodox Rabbis — COR. Seventy-five years later, that same commitment to community and integrity stands behind every seal.
