My Mentor

Michael Maccoby, who was trained as a psychoanalyst by Erich Fromm, served on my doctoral dissertation committee. We worked together extensively with leaders in a variety of organizations and wrote several articles and training resources together.

Work hard, play hard.

When I’m not working I can often be found outdoors: hiking, surfing, skiing or snowboarding, mountain biking, tending to the garden, or on a motorcycle.
