"The nurse was SO funny and friendly, all of the people working in the office were sweet and helpful, and the doctor was so informative. I felt listened to and felt like I really understood the full extent of the processes I was going to go through."

"Dr Brenner has seen me since 2012. She diagnosed me and helped me through my ups and downs. She cares, she listens and always just wanted to make me feel better. She is knowledgeable and really explains things so you understand what is going on. I refer anyone that needs a GI doctor to go here. The staff went above and beyond to help me with an insurance issue as well..."

"My visit with Dr. Rufner was good but trying to communicate with the doctor and office is impossible. Six calls last week and no response. Makes me concerned about a response from him should there be difficulties after a procedure."

"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."
