Dr. Schwartz is a board-certified Staff Psychiatrist at Talkiatry.

Using his knowledge in psychiatry and consult-liaison psychiatry, Dr. Schwartz's interests include depression, anxiety, ADHD, obsessive compulsive and related disorders, transgender patients on hormone therapies and post-surgical transition. He also has an extensive interest in medical illnesses with a psychiatric component such as cancer patients, transplant, HIV, and many others alike.
