After completing his psychiatry residency in 1988 at George Washington University Medical Center, Dr. Greenblatt went on to pursue a two year fellowship at John Hopkins University School of Medicine to become board certified in child and adolescent psychiatry. Following the fellowship, Dr. Greenblatt noticed that the treatment model in psychiatry relied solely upon symptom-based recommendations for medication with little consideration for the underlying biological mechanisms that may be contributing or causing symptoms. This prompted Dr. Greenblatt to develop an outpatient clinic to provide patient-centered care utilizing nutritional interventions to help patients achieve relief from their symptoms. Dr. Greenblatt has devoted his career to educating his colleagues, clinicians, and patients how integrative medicine can have profound effects on mental wellness and how to employ balanced, integrative strategies in the treatment mental illness. Dr. Greenblatt has published multiple books sharing his clinical expertise on how to treat complex mood and eating disorders utilizing an integrative approach. Dr. Greenblatt currently serves as the Chief Medical Officer at Walden Behavioral Care and serves as an Assistant Clinical Professor of Psychiatry at Tufts University School of Medicine and Dartmouth College Geisel School of Medicine.
