Advanced Clinical Strategies for Complex Trauma and Dissociation (2026 Past Presidents Seminar)
Join ISSTD for this two-day seminar featuring past Presidents Colin A. Ross and Steve Gold. This seminar will explore advanced, theory-driven approaches to treating complex traumatization, complex dissociation, and their extensive comorbidities. Grounded in developmental psychology, mammalian attachment, and comprehensive case conceptualization, this seminar bridges two pioneering models: Trauma Model Therapy (TMT) and Contextual Trauma Therapy (CTT).
On day one, Colin Ross will present Trauma Model Therapy (TMT), explaining its core principles—such as attachment to the perpetrator, the locus of control shift, and self-blame—and demonstrating clinical techniques for treating complex PTSD, dissociation, and extensive comorbidities across diverse practice settings. On day two, Steve Gold will introduce Contextual Trauma Therapy (CTT), detailing its conceptually driven, phase-oriented model that distinguishes between traumatic exposure and early developmental deprivation to remediate complex dissociation and disturbances of self-organization.
Target Audience
Those seeking to participate in this seminar must be licensed mental health professionals (psychiatrists, psychologists, clinical social workers, mental health counselors, accredited psychotherapists, etc.). ISSTD staff will audit license information prior to the start of the course and may request additional documentation for your license.
We do accept students enrolled in a program of study leading to a degree or certification in the mental health field and who have an interest in trauma and dissociation. Students must submit proof of student status such as a transcript or registration record. For those who have completed their degree and are currently in the pre-licensure stage practicing under the license of another clinician, you must provide the name and license information for the person you are working with. Documentation should be sent to ISSTD staff at [email protected] before registering.
This webinar is at the intermediate learning level.
