The state Medical Examining Board Tuesday suspended the license of a Shelton doctor for two years and placed his license on probation for four years after accepting a hearing panel’s finding that his paranoid behavior is affecting his ability to safely practice medicine. The first two years of the probation runs at the same time as the suspension, which will be followed by two years of probation, the board’s memorandum of decision states. During the probation, Dr. Nami Bayan must see a therapist. After the suspension ends, Bayan will not be allowed to have a solo practice and must practice medicine in a setting with other physicians during the probation, the order said. In July, the state Department of Public Health had ordered Bayan to undergo a psychiatric evaluation after he had sent emails to the department alleging “corruption and organized crime” in the U.S. medical system, law enforcement and DPH, the memo said.
