“This concerns my first visit with Dr. Avezzano. I’m 71 years old and I finally found an intelligent gastro. He listened, and listened while I said some mildly weird (but true) details of my crippling journey. I’m ecstatic that this doctor is using modern technology instead of being a one trick colonoscopist. He is a scientist, not an auto mechanic. Exceptional.”
