Dr. Seth Sherman is a board-certified adult psychiatrist who has been in practice for over ten years. At the heart of Dr. Sherman's clinical approach is a strong emphasis on establishing trust, rapport, and therapeutic alliance to help persons to feel and live well and to progress toward their goals, both in treatment and in life. Dr. Sherman begins with consultation, a compassionate, collaborative process of discovery that culminates in a working diagnostic impression and, in turn, treatment recommendations. For those with whom he engages in a treatment relationship, Dr. Sherman provides psychoeducation, medication management, and individual psychotherapy, this last modality predominantly drawing from both psychodynamic and behavioral psychological models to tailor treatment to each patient. On some occasions, Dr. Sherman may believe that additional therapy is needed and ask that you bring a therapist into your care team to provide the best outcome. Dr. Sherman received his medical degree from Stanford University and went on to complete his residency in psychiatry at Harvard University. After completing training, he cultivated a private practice of psychiatry in San Francisco, California, treating persons with a variety of psychiatric illnesses, while also providing consultation and clinical supervision to psychotherapists in day-treatment and office-based practices.

Schmidt College of Medicine in Florida, where, as Associate Director of the Psychiatry Residency Training Program, he provided psychiatric inpatient treatment while bringing leadership, scholarship, teaching, supervision, and mentoring to psychiatry residents and medical students. Most recently, Dr. Sherman worked as a senior medical officer/consultant psychiatrist in New Zealand's public health system, serving local communities with expert diagnosis and treatment for a wide range of mental health conditions.
