Nicholas Nissen, M.D. ^{New! Featured}

Dr. Nissen is a board certified psychiatrist and Diplomate of the American Board of Psychiatry and Neurology. He started his concierge clinic after seeing patients and families disillusioned with the behavioral healthcare model commonly available: short, infrequent, med-focused visits with minimal impact. Nissen Clinic was created to provide personalized, holistic treatment to create real change.

Dr. Nissen is passionate about the mind-body connection and takes a bio-psycho-social approach with each person, implementing evidence-based biological (e.g., medical, sleep, diet, exercise), psychological (e.g., therapy, exposure, learning) and social (e.g., relationships, career, spiritual) interventions.

​Dr. Nissen attended Brown University's Warren Alpert Medical School and trained in psychiatry at Harvard Medical School. While at Harvard, he was Chief Resident of Student Mental Health and researched non-stimulant treatments for ADHD. He is a board certified psychiatrist and member of the American Board of Psychiatry and Neurology.

Dr. Nissen worked as a cognitive behavioral and exposure therapist at the Boston University Center for Anxiety and Related Disorders (CARD) and is certified as a CBT Therapist through the Feeling Good Institute. He specializes in insomnia treatment with Cognitive Behavioral Therapy for Insomnia.
