What People Say About Dr. Chad Koyanagi, MD
Reply
My experience with Dr. KOYANAGI left me feeling hopeless & helpless. This doctor should not practice medicine. His explanation to me re my son's psychotic episode/illness was incomplete and entirely unacceptable. I would not recommend him ever. He was impatient, inconsiderate and frankly reprehensible.
