Dr. Seth Flesher is double board-certified in adult psychiatry and addiction medicine.  Dr. Flesher’s practice focuses on medication management of psychiatric illness without the use of controlled substances.  Typically, he offers this in conjunction with supportive or emotionally focused therapy in 30-minute follow-up visits. However, occasionally Dr. Flesher may believe that additional therapy is also needed and ask that you bring a therapist into your care team to provide the best outcome.

Before joining Talkiatry Dr. Flesher was Medical Director of Advanced Psychiatric Services [complex/high profile cases] at Kings County Hospital and Unit Chief of the Covid19 positive unit.  He was also a clinical professor at Downstate Medical College where he was voted educator of the year numerous times by psychiatric residents and medical students.  Dr. Flesher is a graduate of the prestigious combined 6-year BS/MD program at The Sophie Davis School of Biomedical Education.  He did research at the neuropsychiatric branch of the National Institute of Mental Health, completed his psychiatric residency at St. Lukes/Roosevelt Hospital, and he received his master’s degree in public health from Columbia University.

Dr. Flesher believes that psychiatry should start with a thorough assessment to arrive at an accurate diagnosis.  Then a discussion with the patient of the different evidence-based options available.  Followed by shared decision-making to arrive at an effective treatment plan to achieve the goals that the patient identifies as being important.  This should be done in an honest, open, non-judgmental, but realistic environment.  Understanding that the ultimate goal is to get the patient to a position where they will no longer need medication and/or therapy.
