Eccellente service

He explained everything in a very clear, concise, and understandable manner. He did not gloss over the possibility that this could while remote be cancer. He explained the surgery procedure and reviewed the CT scan to show what the concern is and how is would be removed and the slight changes needed to ensure pathology receives it as intact as possible to evaluate.

Dr. Duncan was well versed about my medical history as well as my family's before he walked in the door. He spent a generous amount of time explaining a very complicated condition in terms we could understand. He is a confident surgeon as well as very kind and compassionate. I traveled far for this consultation and he exceeded all my expectations.
