Reviews for EVGH Gilbert - Val Vista, AZ

"I have seen Dr. Nguyenduc and he’s a great doctor. The staff has been nothing but nice and responsive. To the people leaving reviews that they discriminate against anti-vax, what do you expect? He’s a doctor and if you don’t believe in science and medicine, why go see a doctor at all."

"Great experience! This is my second time seeing Dr. Gregory Nguyenduc for a colonoscopy. I have a family history of colon cancer and go in every 3-5 years. Dr. Nguyenduc always listens and answers my questions. He and his staff are warm and professional. This is a big deal to me as it's uncomfortable to go in for this exam! I was called before the procedure and also after to follow up on how I was doing the next day. The doctor always goes over everything before and after the procedure to be sure my questions are answered. He also gave a detailed report after, to my husband. Highly recommend!"

"Dr Spiess Is professional and takes the time to explain things in a way I can understand. She listened to all of my questions and made sure I was satisfied with the answers before I left. I never felt like I was rushed or ignored. I highly recommend her!"
