California-licensed clinical psychologist PSY16190, Mei-I Chang Psy.D. runs a trauma-focused private practice on Fourth Avenue in Hillcrest's 92103 therapist row. Session work concentrates on PTSD, complicated grief, and women's identity issues after loss, overlapping the grief-focused caseload of Rachel Rabinor, LCSW a few blocks south. Dr. Chang's 25-year career spans VA hospital work with combat trauma, forensic evaluations in criminal rehabilitation, and non-profit community mental health serving ethnic-minority populations. Veteran clients needing formal neuropsychological testing alongside trauma therapy are co-referred to the UCSD research group led by Elizabeth W. Twamley, PHD. Treatment methods draw on prolonged exposure, cognitive processing therapy, and depth-oriented grief work. The most demanding cases combine PTSD from sexual or combat trauma with unresolved cultural-identity grief and substance relapse, requiring multi-year integrative treatment.
