Jason Holley is a licensed Clinical Mental Health Counselor (LPCC) and a faculty member at Southwestern College, a consciousness-oriented graduate school awarding masters degrees in Counseling and Art Therapy. He works with astrology as an adjunct to psychotherapy — a way of hearing from the psyche akin to work with dreams and images. He lectures in Santa Fe and at national and regional astrology conferences.

Jason’s teaching is richly informed by his psychological client work, but equally infused with his love of myth. He has a unique talent for making myth come alive in a way that’s both easy to understand, but also leads to deep reflection on astrological signatures. Students interested in delving into the complexity of the psyche will love his work.
