"Dr. Brenner took the time to listen to my concerns and provide guidance to help me feel better. I’ve seen many doctors and Dr. Brenner helped me finally feel better and figure out what was causing my issues. Thank you Dr. Brenner!"

"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."

"I don’t like going to doctors but Dr. Rufner makes my appointment a breeze. He goes over my records and discusses everything with me in detail and then come up with a game plan to go by. I would recommend Dr. Rufner to anybody his bedside manner is out of this world."

"I have had ulcerative colitis for about 20 years. I was diagnosed when I was in 4th grade. Over those two decades, I have had doctors who don’t take into account how I am doing. Just what my test results say. Dr. Rufner is not one of those doctors. Of course, he relies on test results, but he also values my own personal feelings a lot. He is also VERY up to date on the latest science and has some well-informed suggestions on how I can best manage my condition. I would absolutely recommend Dr. Rufner to anyone looking for help!"

"Amazing doctor, patient first mentality. Takes as much time as you need to really understand your concerns and create a mutual treatment plan. Also, very active in local community in regards to research and alternative treatments. Couldn’t recommend him enough."

"So I'm not a patient of his, but my boyfriend is. So far he has been the only doctor to take his llness seriously. My boyfriend has gastroparesis and it has been a rough couple of years, but we've been lucky to have come across Dr. Rufner. The approaches he is taking have helped us find out so much in such a small amount of time, much faster than his past doctors have performed. Would recommend him over and over."

"I have been a patient of Dr Brenner for approximately 10 years. I have personally referred many of my own patients and colleagues to her. She is exceptional as a physician and kind and caring personally. I found her office to be well organized and well set up to follow covid 19 guidelines. As always, I had a pleasant experience."
