Robert Rosenberg served as chief executive officer of Dunkin’ Donuts from 1963 until his retirement in 1998. Under his leadership, the company grew from a regional family business to one of America’s best-known and loved brands. Rosenberg received his MBA from Harvard Business School, and just weeks after graduating at the age of 25, assumed the position of chief executive officer. After retiring from Dunkin, Rosenberg taught in the Graduate School at Babson College and served many years on the boards of directors of other leading food service companies, including Domino‘s Pizza and Sonic Restaurants.
