"I've been seeing gastroenterologists in various cities for the past 20 years. Dr Kevin Rufner is BY FAR the most informative, patient, kind, and knowledgable doctor I have worked with. He is a member of various advisory boards and study groups around the state and country and so is informed about the latest clinical studies, and he is always willing to take as much time as I need to explain my current health status, his recommendations and reasoning behind them, and address any concerns or questions I have. I have never felt rushed or confused, and even when the news isn't great I leave his office feeling empowered about next steps. I cannot stress enough how much I have preferred working with him over any other GI I've seen. I used to leave my doc's office in tears so frequently because of feeling confused and scared about what I was going through, that I started taking a full day off work whenever I had an appointment, regardless of appointment time. This pattern ended when I started seeing Dr Rufner. I have also never posted a review for a doctor before because I've never had an experience worth sharing until now. I've recommended Dr Rufner to a number of friends and colleagues. I'd also like to point out that every staff member I've encountered at the Colorado GI Ogden Street location has been patient, friendly, helpful, and easy to work with. They've also contributed to my general feelings of ease whenever I need to visit the office."
