Ralph de Similien, MD, MS, M.Ed., MPH, is a board-certified psychiatrist at the UT Health East Texas Behavioral Center. Dr. de Similien provides mental health services and care for patients age 17 and older. “I became interested in medicine, specifically in psychiatry, at a very young age because those I saw in need of care did not have access to it. Growing up in Haiti, you were lucky to have access to a physician and even luckier to ever meet a psychiatrist.”

Dr. de Similien’s interests range broadly in the area of mental health. They include, but are not limited to, minority mental health; public, community and rural mental health; teaching; academic leadership and administration; mental health delivery in the young adult population and studying the negative impacts of the various social determinants of mental health on disenfranchised populations.

Dr. de Similien also speaks French and Haitian Creole and enjoys reading and writing.
