Dr. Gill and his entire staff are first rate. I recently had my third colonoscopy and continue to be very impressed with Dr. Gill and the Endoscopy Group. Dr. Gill is both professional and personable, meets with you before and after the procedure and is someone I feel in whom you can place your total trust.

I cannot praise this combined team highly enough. The administrative side did a great job of preparing me for my procedure and then ensuring my billing was correct; they were very responsive and courteous in handling a couple questions I had. Dr. Gill and his team did a fine job on my colonoscopy. I recommend this provider team enthusiastically!

Dr. Desta and your staff: I thank you from the bottom of my heart for sincerely caring about me. Why do I tell so many of my 50+ friends to do a colonoscopy? Because it is important, and they are in the best care with you and your staff. Forever , and ever, I thank you for taking good care of me. God bless.

Had a very smooth and successful colonoscopy procedure with Dr. Desta and staff. HOWEVER, I would urge the website to have a portal for asking questions and such.

Dr. Gill is very kind and very efficient. He makes sure to cover all the concerns you have in your first appt. Manny, Laura and the staff and Dr. Dorsch were all very caring and made sure I was safe and ready for both procedures I had done. I have already recommended this practice to others.
