A clinical guide to the Conference Room model for treating Dissociative Identity Disorder.

About the book

Drawn from more than a decade of clinical work with people living with DID and OSDD, the book lays out a comprehensive framework for clinicians at every level.

It moves through assessment and structural understanding, the building of an internal Conference Room, the slow work of meeting parts, the role of attachment within a dissociative system, work with persecutor and protector parts, and the long arc toward functional integration.

The book is organized around six through-line cases that illustrate how the model unfolds across years of treatment.

It is written for psychotherapists, EMDR clinicians, and advanced graduate students who want a clinical framework that takes dissociation seriously and treats parts as people with histories, not symptoms to be managed.
