This Dr. James Lee was rude telling us to calm down when we said no to colonoscopy due to my recent colon surgery and my old age. If he can’t make money off of you by having procedures, then he doesn’t want to see you. He told us that point blank. I have never experienced a rude doctor like him ever. I won’t be returning.
