He seemed very nice, competent, explained what he thought should be done and was a good listener.


I would recommend him. He inspired my confidence that he's very knowledgeable and thorough and, even better, anxious to apply those qualities for my well-being.


Core GI providers are the best.


Would definitely recommend him.


Dr.MacMillan listened thoroughly to my concerns and asked me what I was looking to accomplish versus just listening to my symptoms and just sending me home with a new prescription to try. He gave me several options on what we could start with and listened and responded very well to what I was looking for. He also made me feel comfortable by making small talk and getting to know me as a person instead of just being another patient on his roster. I would definitely recommend him to anyone looking for a gastroenterologist.


He listened,explained what the procedure entailed and took the time to answer fully all the questions I had. He was very thorough and patient.


They seem very knowledgeable, but you have to interrupt if you are going to bring anything up during the discussion.


Excellent listener and easy to understand


He's the best.


Very caring and understanding doctor.
