Super sweet people very professional. The facility is very clean. Depending on your procedure they will have you in and out in just a few hours. Arrive early so they get you set up 20 to 40 minutes for the procedure then to recovery and off to home from there.

This was my third colonoscopy, and like the previous two, everything went well. Checking in was easy and discharge was in a timely manner.
