Judith Rybko, (PhD) I am a Psychodramatist, Group Analyst and Jungian psychotherapist. I recently retired from the Academy after many years of teaching and guiding students in their thesis. I was the head of the psychodrama graduate program at Seminar HaKibutzim College, Tel Aviv. Today, I work at a private clinic with groups and individuals, as a psychotherapist and as a supervisor.The book "First act, then Know: Experiencing and Studying Psychodrama and Group Work" (Rybko, 2018, in Hebrew) describes a group process as a case study. The book includes fourteen chapters , each chapter focuses on a theoretical concept, including Holding and Containing; Resistance; Dreams; Mirroring; Stages of group development etc. It is an integrative, (theoretical as well as -practical) book for those interested in group work and psychodrama, novice and experienced alike. and its practical application.
