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: brief, infrequent, med-focused visits with minimal impact. Nissen Clinic was created to provide personalized, holistic treatment to create real change.

He specializes in non-stimulant management of ADHD (e.g., non-stimulant medications, supplement and dietary changes, executive functioning skills) and root-cause anxiety treatments (e.g., exposure and cognitive therapies, medications, and lifestyle changes).
