What People Say About Dr. Roy Matsuyama, MD
I would not recommend anyone going to Roy M. Matsuyama, MD for treatment of an illness. Dr. Matsuyama has treated me with nothing but disrespect, and that I was an inconvenience to his day. When I asked the Dr. to explain the disease he diagnosed me with (UC) he acted annoyed and provided zero help or information. I went to Dr. Matsuyama three times and will most certainly not go back. Bottom line: You will not be treated with sensitivity, care, or respect.
