Complex Trauma Treatment Affiliates (CTTA) are an independent, international network of senior complex trauma therapists and clinical supervisors. The Complex Trauma Treatment Affiliates program is not a comprehensive registry of trauma therapists. CTTA membership is restricted to a carefully selected group of not more than three dozen psychotherapists worldwide.
Oversight of the CTTA program is led by Dr. Joseph Spinazzola, Ph.D. and Dr. Jana Pressley, Psy.D., internationally recognized scholars, educators, clinicians, and clinical supervisors in the area of complex traumatic stress. Membership in the CTTA program is by invitation only, and is based on longstanding demonstration of advanced clinical expertise treating children, adolescents, families, adults and/or couples impacted by complex traumatic stress, dissociation and related conditions. All affiliate members offer outpatient psychotherapy services either through private individual or group practices or trauma specialty clinics. Affiliates participate in a monthly peer-reviewed group supervision and resource sharing series facilitated by the Complex Trauma Treatment Center Boston. All affiliates are versed in multiple innovative and evidence-based approaches to treatment.
Unless otherwise indicated, psychotherapy and other services are provided by Affiliates on a self-pay basis, with documentation assistance offered to clients seeking out of network insurance reimbursement. Facilities are handicap accessible only where indicated.
The CTTA is hosted by the Foundation Trust, a private operating foundation in Melrose, Massachusetts with a dual mission – to improve understanding and response to trauma and adversity by training multidisciplinary professionals and developing educational materials disseminated on complextrauma.org, and to actively develop new programming in partnership with small to medium-sized New England nonprofits to better serve high-risk populations and elevate underrepresented communities.
