Margaret (Meg) St John, Ph.D.

Senior Consultant

Meg is a clinical and developmental psychologist (Stanford, U. Michigan, Harvard). She was introduced to Dan’s approach to the mind when she worked for him at Harvard ~40 years ago. In that shared venture, Meg came to know Dan’s compassionate focus on healing, his quick cuts to the pith of a subject and his skill at transforming complex subjects into relatable experience and deep understanding. They teamed well and have been respected colleagues, teacher and student, and trusted friends ever since. By now, Meg has a broad background in the study, teaching and practice of Buddhism and meditation, and especially in the Pointing Out Way. With Dan’s oversight, she follows students in this tradition, guiding them in a style that is relational and collegial, as they metabolize the path to direct realization.
