Many Rotarians consider the Secretariat simply another name for the RI World Headquarters in Evanston, Illinois, USA. Actually, it is much more. While it does include the World Headquarters, the Secretariat encompasses nearly 800 individuals working to make Rotary International run smoothly and effectively. The term describes the entire operations of the general secretary and his staff. The Secretariat also includes eight Rotary Service Centers around the world, all of the staff serving in those centers, as well as all staff assigned to The Rotary Foundation. Its sole purpose is to serve the clubs, districts and administrative officers of Rotary International and the Rotary Foundation. RI World Headquarters, in a building called One Rotary Centre in Evanston, is the headquarters of the Secretariat. One Rotary Centre, as it is called, enhances the efficient operations of Rotary International.
