While outstanding clinical education is important, we at OEC also feel that the experience is equally important. We design conferences to allow attendees flexibility in getting outstanding clinical continuing education and the opportunity to enjoy the facilities and surrounding area. In addition to securing golf and spa credits for attendees, we also plan lectures to ensure enough time to enjoy Scottsdale and surrounding areas, lay back and relax, and make travel home easier with an early end time.
