From start to finish, the visit was quick and the nurses were very kind and helpful. Dr. Sowerby stopped in prior to the procedure as well as the anesthesiologist which helped to alleviate any anxiety about the procedure. The nurses were there for the post op and all went well.

Dr. Sowerby makes me feel like he is my family doctor, even though we've only ever met three or four times. He takes the time to explain things in simple terms and inspires great confidence. I can't think of a better practitioner to look after my gastroenterology needs.

The nurse who reviewed and set up my appointment not he phone took time to listen and answer all questions about the prep and was very reassuring. Dr. Sowerby was very patient and calm about explaining the anesthesia, and allowed me to choose for myself whether to have it. The anesthesiologist (Sergio) was likewise willing to take the time to reassure me and explain the procedure. Everyone was kind and friendly, which made for a comfortable and speedy time at the endoscopy center.

I really like the way Dr. Sowerby takes time to explain conditions, procedures, etc and answer my questions. I don't have many questions because he anticipates most of them.
