How likely are you to recommend Dr. Duncan?

(Select your rating)
Dr Duncan is fantastic. He spent nearly an hour with me pre-surgery just going through the surgical plan and answering every question I had. He has a great sense of humor and compassion, and really put me at ease. The surgery went exactly as he explained it. Recovery and healing have been exactly as I expected. I would recommend him to anyone.
