Dr. Schwartz is a board-certified Staff Psychiatrist at Talkiatry. He completed his residency at Bergen New Bridge Medical Center in Paramus, New Jersey, where he excelled in his leadership and knowledge, becoming the Chief Resident in just his third year of residency at the busiest outpatient behavioral health clinic in New Jersey. Upon completion of his third year of residency, he went on to become Chief Academic Resident of his program, which allowed him to bestow his knowledge of psychiatry on younger psychiatrists in training. After completing his residency in General Psychiatry, he went on to complete a fellowship in the prestigious Mount Sinai Health System in New York City, based primarily out of the Beth Israel location. During this fellowship he studied Consultation-liaison psychiatry, also known as psychosomatic medicine.
