So thankful for Dr. Nightingale. Had a wonderful experience! He takes the time to explain everything, and it is clear that he cares and wants to help you. The office visit was very efficient as well, I got back and was seen by the time of my appointment. It was around 30-45 minutes from my arrival to when I was heading home, and that is as a new patient.

Adultgastro was totally amazing. Staff kept me informed every step of the way. It was so much easier than having it done at the hospital. I give Dr Nightengale n 11 out of 10.
