CANTON, MASS. — The presidents of Dunkin’ Donuts U.S. and Canada and Baskin-Robbins U.S. and Canada will have added responsibilities after parent Dunkin’ Brands Group, Inc. said it would like to accelerate the growth of both brands worldwide.

Paul Twohig, president of Dunkin’ Donuts U.S. and Canada, will assume responsibility for the Dunkin’ Donuts and Baskin-Robbins brands in Europe and Latin America. He also will oversee global development for both brands. Mr. Twohig joined Dunkin’ Brands in 2009. Prior to Dunkin’ Brands, he held leadership positions with Burger King, was chief operating officer for Panera Bread Co., and division senior vice-president for Starbucks.

Bill Mitchell, president of Baskin-Robbins U.S. and Canada, will add the oversight of Dunkin’ Donuts and Baskin-Robbins in Korea, Japan and China to his portfolio of responsibilities. Mr. Mitchell came to Dunkin’ Brands in 2010 from Papa John’s, where he had been president of global operations.  Earlier in his career he was with AFC Enterprises (Popeye’s) and with PepsiCo, Inc. on the KFC management team.

Responsibility for the company’s brands in the Middle East and Southeast Asia will remain with John Varughese, vice-president. Mr. Varughese also will begin to oversee both brands in India.

As a result of the changes, Giorgio Minardi, president of Dunkin’ Brands International, will leave the company.

“I am excited about the enormous opportunity that exists internationally for Dunkin’ Donuts and Baskin-Robbins, and believe we can almost double our current number of restaurants outside the U.S. to 15,000 locations,” said Nigel Travis, chairman and chief executive officer of Dunkin’ Brands. “By broadening the roles of Paul Twohig and Bill Mitchell, two seasoned and successful executives, we plan to apply the processes and disciplines we have used successfully in the U.S. to our international operations.  Both Paul and Bill are proven operators with global experience, and their appointments should enable us to better leverage our resources on a global basis, better support our franchisees, and accelerate the profitable growth of our brands around the world.”
