Michał Lewandowski – Chair of Gestalt Practitioner in Organizations

Michal combines organisational consulting, training and coaching activities with psychotherapeutic practice.Affiliated with the Faculty of Psychology, University of Warsaw. Founder and leader of the School of Gestalt Practitioners in Organizations in Poland. 

"Mature and emotionally resilient individuals form effective teams. At the same time, a system such as a team or organization is able to strengthen or weaken this individual maturity and resilience, achieve synergy of individuality, or promote their collision or absence. The mechanisms behind it often determine motivation, creativity, commitment, and satisfaction of people, and as a result, development and even survival of the organization. That is why my interventions cover the individual, th team and organizational levels. It is a fascinating and inspiring process of discovering, correcting, and building together. That's what I do."
