Xavier Diao, M.D., Attending Psychiatrist
Assistant Professor of Clinical Psychiatry
Xavier Diao, MD (he/him) is an attending psychiatrist at the University of Pennsylvania. At Penn, he is an Assistant Professor of Clinical Psychiatry at the Perelman School of Medicine and a Senior Fellow at the Leonard Davis Institute of Health Economics. He earned his undergraduate degrees in Psychology and Biological Sciences at the University of Maryland, as well as his doctoral degree in Medicine. Dr. Diao completed his psychiatry residency training at the Icahn School of Medicine at Mount Sinai, received further training in child and adolescent psychiatry from the bi-campus program at Columbia and Cornell, and finished a psychoanalytic fellowship at the New York Psychoanalytic Society & Institute.
Dr. Diao believes in the integrative model of psychiatric treatment—that patient-centered care is optimized by evidence-based medication management and collaboration with therapists and counselors. His therapeutic orientation is informed by psychodynamic, cognitive behavioral, and dialectical behavior modalities. He has expertise in the treatment of a diverse range of mental health issues, including depression, anxiety, ADHD, and PTSD. Dr. Diao uses a developmentally-informed, trauma-focused, and LGBTQ-affirmative approach in his practice, with the aim of enriching meaning and alleviating suffering in the domains of love, work, and play.
