Put you at ease, explained procedures to you. Didn't just go for the easy option, gave you alternatives.

Your trust is our top concern, so providers can't pay to alter or remove reviews.

Alistair is a highly regarded colorectal surgeon and I send many of my patients to see him for an opinion when medically required. The feedback I get from my patients is always very positive and they feel listened to and feel very satisfied with the consultation and management that has been provided. I would not hesitate to refer any of my patients to him.
