A Look at the Month Ahead: A Monthly Series with Diane Trimbath

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, April 4th. Watch an excerpt from the January 2020 lecture below, or view other recent videos here.

Become a Professional Astrologer!

IAA’s Department of Professional Training provides you with a comprehensive education in the practice of astrology. Upon completion of the program, you receive a diploma from IAA, and you are eligible to receive professional certification from a number of international astrological organizations.

Registration for Spring Semester is now open.

Most classes begin in April 2020. Many classes in the Professional Training Department are also available to audit. When offered, you can audit a class for a lower tuition fee if you do not require the class for credit to graduate. When you audit a class, you are not required to do homework or pass any exams, but you also will not receive any credit. Use the correct link to register, depending on whether you need the credit or not. Not all classes offer the audit option.

Regular Monthly Webinars and Pocket Courses are always open to everyone.
