Went to WAGI for my first colonoscopy at age 50. Everyone was very pleasant and made the experience as enjoyable as possible under the circumstances. I never felt like they were rushing things like sometimes happens with routine procedures like this where they have to give the same information to every patient. The facility appeared to be very clean. I opted to have my colonoscopy performed without any sedation or anesthesia and they explained things and asked me how I was feeling at multiple times during the procedure. Appointment was scheduled for 7:30 and I walked out of the building before 8:00. My only complaint was that it took a few times to get through to a scheduler over the phone when I had a question. But once I did, a nurse quickly called me back with an answer.
