Founder/Guiding Teacher

Susan Gillis Chapman

Susan is a retired Marital and Family therapist who has been practicing mindfulness meditation for over 35 years.  She is the author of the book The Five Keys To Mindful Communication.

Susan has a unique background that combines expertise in western relationship psychology with spiritual practice.  After receiving an MA in Buddhist and Western Psychology she spent ten years working with victims and perpetrators of domestic violence.  During that time she worked as the program director for a battered women’s shelter and as the clinical director for a counseling center that offered both prison and community based treatment programs for men who abused women and children.

More recently Susan’s focus has been intentional community building.  When their children reached adulthood, she and her husband Jerry joined a small community of 14 people and spent three years in a Tibetan Buddhist retreat.  From 2002 until 2008 she and her husband lived in the Shambhala Buddhist monastery, Gampo Abbey, under the mentorship of Pema Chodron.  Here the models that were born from working with domestic violence took their final form as examples of ‘a radically fresh approach to human relationships.’ The power of intentional friendship enables us to use conversation in a new way, bringing compassion to the parts of ourselves we’re afraid of and learning to unmask and open to who we really are.
