    "Excellent and informative tele-health appointment on July 15 with Dr. Rufner, who is always personable and who gets to the nub of the matter and explains clearly whatever action is next required. Inspires confidence. A+"

    "Dr Brenner was very helpful with my stomach and throat. She explained the 3 items that I may be having. She decided to start with a "Flip". Scheduled this for Dec 26. After results, she will go to the next step."

    "If it matters, I had a good experience. My procedure was painless, I feel good the next day without any adverse effects. They even called the next day to make sure I still have a pulse. Never hard to get them on the phone and everything was spelled out nicely. I recommend."

    "I have spent plenty of time in doctor's offices and hospitals and unfortunately am only 30. I have genetics that make me very prone to colon cancer, so I met with Dr. Frank and had a colonoscopy done as a result. They found a polyp, removed it and I have a plan moving forward. Overall, with Dr. Frank and everyone in the office, they were extremely pleasant all the way over to the Denver Endoscopy Center. I have had terrible experiences and this was the complete opposite. I had also called another local gastro group and received a different experience. Regarding the poor review below about insurance and costs. I can't remember her name, but a representative of the office reached out to me about my insurance, clearly explained costs, potential for payment options, etc. Since I am young, my insurance didn't off the bat consider this preventative. I had genetic testing done and she was able to detail what I needed to do with the insurance company to get it to be preventative. She even allowed me to merge a call with her and my insurance provider. Couldn't have been happier. Thank you."
