Rabbi Dr. Jonah Gewirtz

Rabbi Dr. Jonah Gewirtz is STAR-K’s Global Management Consultant. Among Rabbi Gewirtz’s many claims to fame, is the role he played in the kosher certification process of Baskin-Robbins, the world’s largest chain of ice cream specialty shops. Those in the industry, perhaps, best remember him for his tireless efforts in assuring that every major U.S. steel company that produces steel for use in food packaging switch from a tallow based to a vegetable based butyl stearate oil.
