About Joshua Rosenthal: Joshua Rosenthal is best known as the founder of the Institute for Integrative Nutrition (IIN), which he established in 1992. IIN has grown from a small classroom of 20 individuals in New York City to the largest nutrition and health coaching school in the world, with over 100,000 students and graduates in more than 155 countries. Rosenthal holds a Master of Science degree in Education with a specialization in Counseling from Duquesne University.
