Dr Cantillon had the best greeting I have ever gotten from a Dr. when he came into exam room, he introduced himself and said "Thank you for coming to see me".

Dr. Cantillon is wonderful. He apologized over and over for being behind. He took his time with me even though his afternoon patients were fast approaching and he still needed to eat lunch. His compassion for his job shows. I absolutely loved that he talked about the importance of lifestyle plays a big part in my health. I feel as though many doctors just want to prescribe medications to treat the disease versus promoting ways to prevent them or prolong life without them.
