We found this doctor to be very knowledgeable, very easy to talk to about conditions, and his staff equally is good. So we would highly recommend him if someone else was looking for a doctor of his type.

I arrived at the reception and I was asked to fill in 3 pages with all of my information. I told her I have already check in online and she told me that I had to do it all because the waited the papers. I spent 23 minutes filling in all the same information I previously enter. What is the point of doeing a check-in online if you have to fill in everything again. I was expecting a copy with all of my information and just to sign it. I'm not happy about that.

The staff is the best I've ever seen. Every one of them are encouraging, helpful, that's including the nurse. Dr. O'Reilly draws pictures, he explains things, and he doesn't take you into surgery or tests without checking everything out. I've got several tests now scheduled. They're the best. I can't say any more about them. They're wonderful.
