In this paper, I propose integrating group theory into relational psychoanalytic training to create structural change within psychoanalytic institutes. I argue that candidates should undergo mandatory experiential participation in small, medium, and large group settings to enhance clinical competence and institutional awareness. Drawing from my experience directing the Institute for Relational and Group Psychotherapy, in Athens, Greece, I highlight how group dynamics—particularly within large groups—can deconstruct hierarchical idealizations and foster more authentic, horizontal relationships among trainees and faculty. I suggest rotating group supervision models and shared leadership structures as institutional mechanisms to promote democratic participation and reduce abuses of authority, so that candidates are equipped to recognize and work with both sibling and institutional transferences. By embedding group theory into the heart of psychoanalytic pedagogy, I contend we can create more ethically responsive, inclusive, and resilient training environments.
