Message from Program Director Tolu Olupona, M.D., DFAPA


"Welcome! I thank you for your interest in our program. We provide a unique educational experience in multiple, comprehensive psychiatric treatment services within One Brooklyn Health Interfaith Medical Center. During the first and second years of training residents rotate through our inpatient acute psychiatric treatment units, extensive substance use disorder units, consultation/liaison service, psychiatric emergency room, medicine and neurology service. Outpatient rotations take place at three sites, our Center for Mental Health, Bishop Walker Clinic and Behavior Health Program. Together these sites provide a diverse range of patients that span all socioeconomic and ethnic groups. Residents work with skilled faculty members who are dedicated to teaching and training future psychiatrists. We provide a supportive learning environment. We are committed to maintaining a personal, supportive individualized training approach that enhances the strength of each resident.  


Our mission is to produce psychiatrists who are erudite, excellent clinicians, compassionate, and genuinely committed to meeting the mental health needs of patients both at home and globally. We have developed a “buddy” whereby each resident is assigned from the outset to a more experienced peer. We encourage close supervisory relationships with faculty. Furthermore, we have an open-door policy for problem-solving with Chief Residents and Faculty.   

Once again thank you for your interest in our program. I look forward to meeting you."
