    "Stomach issues are no joke, and I wanted to start this review off by saying that I've gone through six or seven years straight with severe abdominal pain, nausea, sickness, missing school, missing work, doctor appointments, pills, and various diagnoses that have not helped me at all. It's hard to find someone that can help. Then I found Dr. Brenner. When I went into the office for the first time, I was extremely nervous and had little hope for help. The staff was very sweet. But when I met Dr. Brenner for the first time, I was expecting her to be like all of the others. I can officially say that I am now in remission after seven years thanks to her. She examined my previous medical reports without bias and listened to me with understanding. She had told me that there was no proof I had any of the diseases that these other "doctors" were diagnosing me with, that I didn't need to take all kinds of pills, and gave me advice and tips on how to help myself with home remedies with whatever I may be going through (severe abdominal pain for example). I'm now thankfully taking one pill that for sure helps me, but is not required, and I can eat all kinds of food now that I've never been able to eat. Dr. Brenner is sweet, honest, and very caring with her work. I plan to go to see her for as long as I can."

He took all the time I needed to answer my many questions and make me feel very comfortable going forward with my procedure, especially in this time of Covid-19! Dr. Rufner has a very kind and understanding manor and I would highly recommend him to anyone looking for a gastroenterology doctor!"

    "Dr. Rufner is excellent. This was only my first appt. so I will come back and update this review after my second. I was able to really talk to him and tell him everything and he listened really well and explained in detail what I needed to be educated on and the procedures we would be doing together to find answers to get to recovery. I also can't say enough good things about NeNe his scheduler. She has a great caring personality on top of being efficient. What a find in an employee. I will again up date this later but I recommend going to him for any GI needs."
