Why do people work? When are they willing to change the organization? As a consultant, Erwin is searching for answers to these questions for more than 30 years. He works as a projectleader, teamcoach and change management consultant and he is also active in interim leadership as well. Moreover, he is a researcher for crises in the political field. The experience he has gained and the fun in doing this have not been unnoticed, since he has won several prices for his consultancy work. As an ex-diplomat, Erwin is familiar with working in an international field and likes the nomadic way of life. If the old motto "Alle Menschen werden Brüder" comes around after an assignment, it was successful for him.
