The O.A.A. is a regional association of professional, non-professional and student astrologers serving the astrological community in Oregon and Southwest Washington. Each year from September through June, we offer a series of quality lectures and workshops given by well-known professionals, practitioners, and educators. Members are also invited to a number of social events during the year to promote camaraderie and community. We welcome all those interested in the study of astrology and look forward to seeing you at the meetings and lectures.
