Patient Reviews
Feb 12, 2022
I can't fathom how anyone could give this doctor a less than 5 star review. Dr. Dreznik is thorough and companionate. His nurse was very helpful as well. At no point do you feel rushed or looked over. I would, and already have, highly recommend him to friends, family, and anyone who needs a good GI doctor for that matter.
