When you audit a course, you are not required to do homework or pass any exams, but you also will not receive any credit.

Diane Trimbath

Diane Trimbath

Join Diane Trimbath to learn about new opportunities or “shifts of focus” in store for us each month, as she reviews the energies coming in from our sky in IAA’s new monthly series, “A Look at the Month Ahead.” Find out how, when, and where these changes may influence YOUR life (based on your Sun sign). Diane will be holding these meetings once a month, but registration for each meeting is separate — you do not need to sign up for the entire series or make any long-term commitment. Everyone is welcome, you do not need any astrological background to participate. Visit the registration page to see the scheduled dates. The next meeting is Saturday, December 5th.
