The Program Committee, under the leadership of Bob O’Toole and Mike McKee have created an outstanding program that includes cutting edge clinical and basic research from around the world. The quality of scientific sessions is evidenced by the observation that one quarter of all podium presentations this year are reporting on prospective randomized trials. Each Steven A. Olson, MD attendee can benefit from this year’s Annual Meeting in some way, and I encourage you to carefully review the program and select a track that best suits your needs. As our organization has grown so have the opportunities for attendees to take advantage of. These include the Basic Science Focus Forum, International Forum, OTA Grant Writing Workshop, Orthopaedic Trauma for PA & NPs and a plethora of full and mini-symposia, including Industry and Health policy symposia. Additionally, the Annual Meeting will offer an unprecedented number of opportunities to network and interact with friends and colleagues. This year’s venue at the Gaylord National Hotel & Convention Center is exceptional. There are social events every evening: the international reception on Wednesday, the welcome reception and fund raising auction on Thursday at the Gaylord National, and “suds and science” guided poster tours with beer and wine in the exhibit hall on Friday evening. Please also join me in extending a special welcome to our guest nation attendees from India, international attendees, and SIGN scholars from Kenya and the Philippines.
