IDM is at the forefront of institutions teaching new and profound findings about adult development 
Managers, Management Consultants, Coaches, Mediators and Educators need to build effective helping relationships. If you are a human resources professional or otherwise responsible for leading people, you will definitely benefit from insights practiced and taught at the Interdevelopmental Institute (IDM).
Once it is understood that the cognitive, social-emotional and psychological characteristics of a person have to be integrated in order to understand a client’s developmental challenges, one’s professional landscape changes from a flatland to a landscape with peaks and valleys in which clients can be transparently positioned. There is no magic to that, only an effort to identify and learn how adults actually develop over their life span, and what this means for how they behave in the world.
