I work independently, but not alone.

In most of my activities I collaborate with others. There are organizations that I am f0rmally affiliated with, a member of, or registered with. Collaboration also takes place within a large informal network of like-minded consultants, educators and academics. Lastly, there are education programs that I help shape. In this overview I limit myself to present day collaborations that have been stable for years. You can learn more about them by clicking on them.


I am affiliated with three organizations:
•    Associate partner Twynstra Gudde Consultants and Managers. We work together in management consultancy en in furthering know how on organizational change.
•    Associate partner Sioo, Inter-university Centre for Development in Organizational Studies and Change Management. We work together in education programs, most notably a ten year involvement in its postgraduate program ‘Advanced Change Methodologies’. I am a member of Sioo’s academic council and its netwerk for action researchers
•    Senior research fellow at NSOB, the Netherlands School of Public Administration. We work together in knowledge creation and transfer, like in an education program on policy, change and language.

I am member of the scientific council of the professional association of management consultants in The Netherlands (OOA) as well as a core member of the association. (Incidentally, it is the oldest one of its kind in the world.) I am a member of the editorial board of the peer reviewed journal ‘Management & Organisatie’, a member or the research platform of Sioo, a member of the Academy of Management, a member of Practitioners’ Council for Critical Organization and Intervention Studies (KOIS) at the University of Humanistic Studies. I am registered as a ‘certified management consultant’ (CMC) and I am registered as a teacher at the central register for vocational education (CRKBO).


I like to work with others, especially to bring different expertise that fuels innovation. Underneath I list some of the collaborations that are frequent or sustained. I can recommend each of them.

education programs

I am involved in educatation programs of Sioo, NSOB and several universities. The latter includes the Copenhagen Business School (CBS/Simi), The Technical University of Denmark (DTU) and the Vlerick Business School. In the Netherlands this includes the Free University in Amsterdam and the Amsterdam and Rotterdam Universities of Applied Sciences. I am also part of programs of the VUCA Academy and the National Centre of Expertise on Social Innovation (LESI) as well as collegetours or masterclasses organized by Vakmedianet or Focus Learning Journeys.

I try to post my participation in the programs that are public on the ‘news’ section of this site when these are in English. Education activities that are not in English are only posted on the Dutch site.
