The faculty of the Grubb School of Organisational Analysis is drawn from a wide range of skilled and passionate workademics. This means that our faculty manage the boundaries between the work in the real life of organisations and the challenge of using that experience in the higher education sector, enabling the development of new organisational theory from the practice of live organisational work. All of our work is approached from an action research orientation and is rooted in the desire to bring learning to the forefront of organisational practice.

The Faculty are all experienced international consultants who have worked at all institutional levels in society on every continent of the globe. They have presented and published their work and thought in books, journals and via all kinds of media. They share the conviction that values, beliefs, spirituality and faith (of all kinds and none) are key resources for offering leadership in today’s world.
