"I had an Endoscopy done by Dr. Nguyenduc last month. It was a super fast and comfortable procedure for me. I’ve had this done in the past and there was no comparison as in the previous times I was awake and didn’t like that. Dr was very personable, very knowledgeable, very professional. His demeanor was pleasant, and I immediately felt I was in good hands. (For me first impression and trust is crucial) His staff were super! They took care of every detail involving appts and follow up. I highly recommend Dr. Nguyenduc if you’re looking for excellent care in your procedure."
