Staff was great. I felt comfortable and well taken care of. Dr. Sarges took the time to address my concerns, and consider different options for treatment/maintenance of my condition. Glad to have him for my doctor!

Excellent care by doctors and nurses. My appointment was 4pm on a Thursday so I was concerned about how energetic the hard-working staff would be at the time of day at the end of the week. I was very impressed with the all of the staff - except the grouchy receptionist - the rest of the group were high energy, patient, detailed, friendly, and professional. Delightful group.

I was super nervous going in for this, but these people were awesome and very professional. Made everything much easier than I expected it to be. The doctor was great and everyone on staff I dealt with was helpful and very nice.

Dr Sarges is gentle and caring. I didn't even need anesthesia for my colonoscopy. He communicates well and made me so comfortable I felt no fear at all during the entire procedure. It's really nice when you find yourself in expert hands. Thank you Dr. Sarges for being the kind of doctor we used to have. Now, after the pandemic, it's rare to find smart professional caregivers who actually spend the time necessary.to inform AND set the patient at ease. Dr. Sarges puts YOU first-not his business.

The staff was wonderful to work with. They explained every step of the procedure and made sure that all of my questions were answered. They also alleviated my concerns regarding recovery. Dr. Dy explained my results and took the time to answer all of my questions. Great experience!

I was very pleased with my procedure today. I had never been to this facility before. It's BIG! But that's not why I give it 5 stars. 5 stars is because the moment I walked in there and went to the front desk, I was at ease. Friendly, friendly staff from the time I went in to the time I left. Dr. Dy and her staff did a wonderful job making sure I was comfortable. Highly recommend!

The entire staff were so friendly and kind. Even though these procedures are routine for them, they still made sure I understood everything, and knew exactly what to expect. Thank you for making the entire process as comfortable and simple as possible.

I am very impressed with Grand Junction Gastroenterology. The people there are very friendly and made me feel very comfortable. The wait time to get an appointment was not very long. They answered all my questions and concerns. I live in Montrose and travel to Grand Junction, so I was very grateful when they squeeze me in for a minor procedure while I was there. They saved me a trip to Junction on another day. I recommend this place very much.

From the time I arrived at the front office to the time I left I was treated with pleasantness sand helpfulness. In the receiving room the staff treated me with patience and kindness in a very professional way, and explained fully what they were going to be doing; I was kept well informed and they were very efficient. Dr. Shields was pleasant and informed me what he would be doing and explained afterwards what he had found and what they did. The whole staff was cheerful and wanted to help. The Grand Junction community should be proud for such a caring unit in their mist.
