Dr. Rosen has an extensive background as a practicing physician. He is formally trained in psychiatry as well as internal medicine, and is Board Certified by the American Board of Psychiatry.

A magna cum laude graduate of Duke University, Dr. Rosen received his M.D. degree from the Emory University School of Medicine here in Atlanta. He then completed his residency in internal medicine at Emory. He has served on the faculty of the Emory University School of Medicine in the Department of Internal Medicine, and practiced internal medicine in Atlanta and later, on Long Island in New York, in private practice. He made a major career shift, going back to train in psychiatry at the State University of New York at Stony Brook, where he was Chief Resident his final year. He then served on the faculty there as a psychiatry attending, while starting his private practice in psychiatry. Dr. Rosen had always felt Atlanta was his true home and returned here in 2014 to open his practice in psychiatry.

Dr. Rosen treats adolescents and adults, ages 10 and up, and manages all aspects of psychiatry. Because of his internal medicine background, Dr. Rosen focuses on the entire person. He prefers to prescribe the least amount of medication possible and discusses with the patient the reasons why medication may or may not be appropriate. While some issues are mostly psychosocial (such as anxiety from life transitions) and may not call for medication, others are more biological in nature, and therefore difficult to treat without medications (such as bipolar disorder and ADHD). Alternatives are always discussed, and in the end, Dr. Rosen believes the client is the person ultimately in charge of his or her own care. Dr. Rosen sees himself as a guide, providing the information and tools so that a patient can reach the personal life goals one seeks, and live as happy and healthy a life possible.
