I never write reviews but Dr. TAZ is the best doctor I have ever had. I had a scare of a spot on my pancreas and he comforted me and moved procedures quickly along to get the diagnosis ASAP for me. My stress level was through the ceiling and he took care of me so well that I could never thank him enough. Other doctors should take note of his bedside manner. As I said the best of the best! He should get 10 star review!

Dr. Taz is a great GI. I started seeing him after having trouble with the office staff at a previous GI and I have never regretted it. Dr. Taz listens to my concerns and does everything he can to ensure I leave the office satisfied.

Dr Taz is a wonderful doctor. I was nervous about seeing a GI doctor but he came very highly recommended from my primary doctor as well as the doctors I work for and he was everything they said he would be, he is very kind and very nice and willing to answer any questions you have for him. I highly recommend him to anyone who needs a GI doctor

Dr. Tasiopoulos is wonderful! He really shows that he cares about his patients and will go the distance for you. He has been my GI doc for a few months and I can't say enough about this wonderful man who has been a God-send for me. He has a large patient load but you wouldn't know it by the amount of time and caring he demonstrates at each and every visit. If you're looking for a doctor that will deliver the highest level of care, see Dr. Taz!
