The AAOS Board of Directors has also worked with the consultants to determine the most appropriate executive structure for AAOS. The Board has approved a structure that features a chief executive officer (CEO) with an executive team, which consists of a director of medical affairs, chief operating officer (COO), chief financial officer, and chief educational officer. The Board of Directors has approved the new structure, and phase-in will take place over the next year. These changes have been made with the Board officers working in collaboration with William Tipton, MD, and Lawrence E. Rosenthal, PhD. Dr. Tipton will continue in his role as executive vice president and CEO until March 31, 2003, and on April 1, 2003, will assume the role of director of medical affairs. In October 2002, a search committee of the board of directors will begin to select a new CEO by or before April 1, 2003. Dr. Rosenthal will continue to serve as COO and has been asked by the Board to assume some additional staff leadership responsibilities throughout this transition. The organizational review was designed to ensure a strong future and to keep AAOS the premier medical professional association that it is.
