Established in 1975, our mission is to advance the principles, practice and profession of organization development. Join us! Our monthly programs are intended to be interactive, highly participatory and supportive of building an effective OD community in the greater Chicago area. If you attend one of our program events, expect to be challenged, stimulated, and energized by both content and people. Monthly program events are held on the second Thursday of each month on the 4th floor of The Chicago School of Professional Psychology, 325 N. Wells (across from the Merchandise Mart). Discounted parking is available nearby after 3:00 pm on weekdays. Continue exploring this website to learn more about our future events.
