After waiting for 30 minutes past my appointment time, I was finally put into a room and had my vitals taken. Another 20 minute wait for Dr. John. By then I was unhappy, and I expressed this to him. He has no bedside manner. Not a great personality. When I had my colonoscopy, he did not say one word to me. Not hello before, or give me results after. One of the nurses present told me my results.
