*THIS PROVIDER CANNOT PRESCRIBE CONTROLLED SUBSTANCES FOR NH PATIENTS* Doctor Phillip Sullivan is a staff psychiatrist at Talkiatry. He is board certified in both adult psychiatry and child and adolescent psychiatry. His interest in psychiatric treatment was originally triggered by the humanistic writings of Abraham Maslow, Carl Rogers, and Rollo May. As he earned his medical degree and started post-graduate psychiatric training, he went on to learn psycho-pharmacological, cognitive-behavioral, and psychodynamic treatment approaches. He combines these perspectives in diagnosing and treating psychiatric conditions including depression, bipolar spectrum disorders, anxiety, stress and trauma related disorders, adjustment problems, maternal mental health, OCD, ADHD and other disorders. His practice focuses on supportive pharmacological treatment, and he sees listening and empathy as essential elements of the treatment process. He strives to provide a comfortable experience in which doctor and patient work together to understand the presenting problems, develop a treatment plan, reduce symptoms, and optimize functioning. Doctor Sullivan supports and encourages concurrent psychotherapy and will work collaboratively with therapists to optimize the best treatment results. Doctor Sullivan received his MD degree from Brown University Alpert School of Medicine. After completing a medical-surgical internship, he went on to a residency in adult psychiatry and a fellowship in child and adolescent psychiatry at Harvard Medical School's Massachusetts Mental Health Center. He has held academic appointments at Harvard Medical School and the University of New England School of Osteopathic Medicine. In the 36 years following completion of his training, he has worked as the medical director of a mental health center on the under-served Eastern Shore of Maryland, as the medical director of a child and adolescent psychiatric inpatient unit, as a staff psychiatrist at New Hampshire's Dartmouth Hitchcock Clinic, and as the medical director of child and adolescent psychiatric services at Concord New Hampshire's mental health center. Before joining Talkiatry, he served for 18 years as the chief of psychiatry at Southern New Hampshire Medical Center where he also spent three years as the hospital's chief of staff.

Dr. Sahadevan took an adventurous path to Talkiatry. After perhaps thinking a little too hard about Intro to Philosophy in college - "the unexamined life is not worth living” - he first used his chemistry degree to work in pharmaceutical research. He changed course, working in computer network engineering, before deciding to find a more meaningful path. He worked as an EMT, then earned a Master's in Physiology before finally landing in medical school at Ohio State. Finding a surprising interest in psychiatry, he stayed at Ohio State for residency, and then a fellowship in forensic psychiatry. He is board-certified in both Psychiatry and Forensic Psychiatry. He previously worked as a forensic psychiatrist and evaluator at Ohio's maximum-security state psychiatric facility, as an attending psychiatrist running an inpatient unit for violent or dangerous patients, performing court-ordered evaluations, writing reports, and testifying when necessary. Dr. Sahadevan has also worked as a consultation-liaison psychiatrist, performing psychiatric consults at several general hospitals in Central Ohio's largest hospital system. He found great enjoyment in teaching successive generations of residents and medical students, serving as an adjunct faculty member at Ohio State, Ohio University, Wright State, and OhioHealth Riverside Methodist Hospital. He is excited for the next chapter of his journey, exploring another area of psychiatry at Talkiatry!
