He was rude, would not listen to my questions. He told me that I had a tiny ulcer in my colon and that it would go away. He also told me that I was crazy and needed to see a mental health doctor, he spoke poorly of other doctors in the Alton, IL area. Also after getting a second opinion due to his rudeness and making me cry, I found out that I really had a large ulcer in my rectum not in my colon. The ulcer needed to be treated immediately. I would NOT recommend him to anyone for anything. In my opinion he is a quack and needs to have his license removed from him.
