Patrick Whitesell is co-chief executive of Endeavor. He and Ariel Emanuel merged their Endeavor agency with William Morris in 2009 to form WME Entertainment, the largest talent agency merger in history. A 2014 deal with IMG created WME | IMG as a sports, fashion, media and events company. Whitesell and Emanuel announced plans to bring back the Endeavor name through a new holding company called Endeavor, which will oversee the WME | IMG portfolio. However, the agency will continue to be called WME. Whitesell had been a partner in the original Endeavor and prior to that was head of the talent department at Creative Artists Agency. He is an appointed member of the California Film Commission and an associate member of the Academy of Motion Picture Arts and Sciences.
