Dr. Thomas Spina is an adult psychiatrist who began his practice at Talkiatry after completing his psychiatry residency at the Eastern Long Island branch of Stony Brook University, where he treated a diverse patient population. Dr. Spina received his undergraduate degree from St. John's University in Queens where he studied Philosophy. Initially interested in a career in law, Dr. Spina decided to change gears and pursue a career in medicine after watching a relative struggle with her diagnosis of Diabetes Mellitus. Dr. Spina then completed medical school at Tel Aviv University in Israel, where he fell in love with psychiatry during his clerkship at Ichilov medical center. During that rotation, he came to appreciate how each patient has his or her own unique story, regardless of their diagnosis. Dr. Spina favors a holistic and integrative approach to psychiatry, combining medication management with supportive therapy, elements of cognitive behavioral therapy, while remaining open to other treatment modalities depending on the needs of his patients. When more focused therapy is indicated, Dr. Spina may recommend that his patient work with a provider specializing in a particular modality of therapy as part of their treatment. Dr. Spina treats adult patients with mood disorders including major depressive disorder and bipolar disorder, anxiety spectrum disorders, OCD, PTSD and specific phobias. In his spare time, Dr. Spina enjoys a variety of hobbies, including Brazilian Jiu-Jitsu, running, baseball, and exploring new eateries and shops.
