I tried getting an appointment with OTHER centers closer to Denver, but took such a long time to get a person - and when I got someone she was so cold. THIS office however 'Endoscopy Center of the Rockies' was WONDERFUL. I got a real person right away, who was so personable and flexible and terrific! Even though I have to drive further to get there, I felt it's absolutely worth it. My husband went last year and he has also a terrific experience. I highly recommend these guys!
