Marriott is reorganizing global operations into four regional divisions: the Americas, Asia-Pacific, Europe and Middle East-Africa

To improve efficiencies, , according to Marriott International CEO Bill Marriott. Former executive vice president of global sales and marketing Amy McPherson will lead the European division while former executive vice president for the Eastern United States Dave Grissen will head up the Americas division, according to officials. Managed separately up to this point, oversight of the Ritz-Carlton brand also will be handled within each newly defined regional division. Some Ritz-Carlton operations will be incorporated into Marriott corporate headquarters to provide regional management teams "a bit more power and the ability to make decisions," according to Marriott president and COO Arne Sorenson.
