I had to travel over 3 hours to get to his office and it was worth it. He was timely, knowledgeable, explained everything in detail and was very nice. His staff wS also very helpful and kind. It was a great experience and even tho the distance is great, I will continue to see only him when the need arises. I have also recommended him to my family. Thank you doctor and staff!! I was there for a scary health situation and you took care of me with great concern and care!!!!
