I underwent a routine colonoscopy and an endoscopy during the same visit to Glen Endoscopy Center. It was a great experience start to finish. I was greeted at checking in a timely manner by a young woman who was helpful and welcoming. Next a nurse took me back to the area where my vitals were taken and routine questions were asked. Over the last year I have become a "diifficult stick" and when the nurse could not get the IV in she called another nurse who specializes in difficult veins and with one stick, it was in! I was grateful! The nurse anesthetist came in to explain the anesthesia and asked mire questions snd confirmed answers to previous questions. Finally Dr.Williams came in to once again explain the procedures and answer my questions and reassure me. Within minutes I was in the procedure room and anesthesia was easy and the procedure went perfectly. Dr Williams came to recovery to explain the findings and a nurse explained what to expect over the next 48 hours and gave me written instructions and pictures taken during the procedures. Tge center calked the next day to make sure all was going well and to answer any questions. All in all it was an excellent and worry-free experience. I highly recommend the Glen Endoscopy Center and Dr. Williams.

Dr. Qazi was a pleasure to work with. From the initial appointment, tests and follow up he made sure I felt comfortable. Dr. Qazi is such a thoughtful, nice and caring doctor. Definitely recommend!

The Glen Endoscopy Center is the only place to go for a colonoscopy procedure. It is a much better experience than going to an outpatient center at a hospital. Staff is great there and they are very caring and compassionate. Once they anesthetize you, you will not wake up during the procedure. I highly recommend going there if you are in need of their services.
