I studied psychology and pedagogy at the University of Amsterdam. Already during my study, I entered into management development. From management development I moved into conflict resolution, then into organizational structuring and finally into corporate strategy. I was one of the first who explored the application of strategic management to the public sector. I have always been involved in counseling to executives and policy-makers. This led to management coaching and what is called nowadays life coaching. I have lived and worked for some time in New Zealand and in Brazil. My consultancy focus is now on organizational constellations and core issue analysis, my therapy focus is on transpersonal regression therapy, and in between these two fields on helping people to develop what I call personal mastery.
