Joanne Twombly’s book is the missing piece of the puzzle in treating dissociative disorders. Her book is an invaluable guide for clinicians applying specific therapeutic modalities to work with patients who have complex trauma histories and/or dissociative disorders. Although attachment and parts work modalities such as IFS, Somatic Experiencing, Sensorimotor Psychotherapy, AEDP, have much to offer treatment of complex trauma and dissociative disorders, none is truly sufficient to navigate the complexities of a deeply fractured inner landscape. Joanne Twombly draws on decades of experience working with dissociative disorders to offer hard won wisdom and practical interventions to provide an essential tool for all trauma clinicians.
