Sebastian Bliss, PhD (he/him) is a staff psychologist in the PTSD Clinical Team at the VA Boston Health Care System. Dr. Bliss has specialized clinical interest in men with disorders of emotion regulation, issues affecting LGBTQ+ service members and veterans, and Written Exposure Therapy.

Dr. Bliss received his PhD in Clinical Psychology from Palo Alto University with a concentration in LGBTQ+ psychology, which included a pre-doctoral internship at VA Northern California. He then completed a two-year postdoctoral fellowship in Trauma Psychology at the University of Texas Health Science Center San Antionio’s STRONG STAR research consortium, where he worked as a clinical research therapist with active duty service members at Fort Hood.

After graduating fellowship in 2020, Dr. Bliss joined the staff at VA Boston, where his role has been primarily clinical. In addition to these clinical duties, he has been actively engaged in the teaching and mentorship of psychology interns and fellows both at VA Boston and at other VA and non-VA training sites. This has included the supervision of trainees as part of the pre-doctoral internship program and the LGBTQ+ postdoctoral fellowship. It has also included providing didactics on a range of subjects such as military culture, military sexual trauma, and Written Exposure Therapy. Starting in the 2026-2027 academic year, Dr. Bliss is excited to also begin specialized training and supervision on practical applications of Dialectical Behavioral Therapy with advanced medical residents through the Harvard South Shore Psychiatry Residency Program.

Dr. Bliss deeply values his role as a consultant for therapists learning Written Exposure Therapy, a brief, evidence-based, trauma-focused treatment for PTSD. He has served in this consultation role for a range of programs and projects both within the VA and for outside organizations, including community mental health agencies and clinical networks providing evidence-based care to veterans and their families. He looks forward to more opportunities to help therapists learn this broadly applicable, effective trauma treatment in the years to come.
