"Dr. Dennert is such a kind, well mannered physician who really spends time with you to ask you all about your digestive health as well as any problems you are having she should be aware of. Some doctors just seem like they want to get you in and out as soon as possible, but exhibit no warmth, compassion, humor, or personality. Not Dr. Dennert! I'd highly recommend her!"

"Dr. Dennert is the most understanding doctor that i have had. She listens carefully and together we are managing my Crohn's disease. The staff and medical assistant Blanca are very kind and also mindful of people's time. I've been to some doctors where they had me waiting in the front office and exam room for over an hour! Not at Arizona Digestive Health!!! I'm so grateful to have found such a caring and compassionate doctor to help me manage my condition."

"I had to look for gastroenterologist because I was not happy at all with the doctor I had. Particularly when I learned that he doesn't meet with patients any longer. His assistant does. So, I was very skeptical when I came to my first appointment. Needless to say that now I'm extremely happy with Dr. Brenda Dennert. She listens, advise suggest and discuss the process with me. I personally think that many doctors have the knowledge, but they are not very good with relating to their patients or capable of advising and guiding their care. Dr. Dennert should have six stars."

"My mom had an appointment with Dr. Dennert. While the wait time was a longer than I would have liked (but par for the course with doctors!), the nursing staff was kind and helpful. Dr. Dennert took her time with my mom and got a full history. When we left, we understood what the doctor believed/concluded about my mom's condition and the next steps in her treatment."

"Dr Dennert is a GI doctor everyone could be extremely happy to see. It was my first visit and from the minute I made my appointment speaking to Lupe I knew I was in good hands. What a sweet, understanding and compassion person. At my appointment Dr Dennert took a lot of time with me having me explain my problems and answering all my questions in a manner that I could completely understand. I found her extremely competent and caring. I have already given her name to a dear friend. I totally appreciate all Dr Dennert did for me."

"I have been a patient of Dr Dennert for 20 years. The one thing that I worry about is that she will retire some day. Dr Dennert is a great doctor who actually listens to you when you are telling her what medical problems you are having. She is sincere and cares about your health. I have referred my friends to her and they are very pleased with her care."
