InterPlay was founded by Milena Mutafchieva and Stefan Flegelskamp with the idea of providing trainings and seminars in international groups, healing children through play, and carrying out international projects in order to promote intercultural tolerance, provide help and support to those who need it, and to conduct research within the field of psychodrama. Currently, InterPlay has four international training groups for psychodrama with children.
