"Personable, Knowledgeable, Understanding, and informative."
"Friendly staff, Thomas was very fast but thourough, and I was also recomended by a family member who had a good experience."
"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."
"Dr Rufner takes time to carefully explain about your condition. He is very knowledgeable and compassionate!! I highly recommend him!!"
"I have been a patient for approximately 8 years and am more than satisfied in the care and guidance I receive. I have recommended him numerous times through the years."
"I am very happy with the way dr Brenner treated my problems . It deserves 5 stars, but I just want to complain about their answering service. It is very difficult to call them , It happens many times that they don't answer the phone , they leave me on hold then it is disconnected and they never call back, I leave an urgent message with the answering service ( I was feeling very dizzy after taking a medication for my problem...) and they never call me back , So I had to call another doctor to reassure me and answer my question....... And so on.... It is a pity to have a very good Doctor with a very bad answering service. You cannot rely on it"
"Great doctor, very thorough, takes time to explain diagnosis in detail. Excellent professional and personal manner. Only complaint is very poor telephone appointment system"
"I had a great experience seeing Dr. Rufner. He was exceptionally friendly and professional, listened carefully to my conditions and concerns, and most importantly he explained the medical information very clearly. Would highly recommend him."
"Dr. Rufner has been my best gastroenterologist and I've had quite a few. I've had some say they didnt know what was wrong but Dr. Rufner knew what it was and how to treat. I have been going to him about 6 years and highly recommend him."
"Dr Brenner takes the time to truly listen to you to figure out the root causes of your concerns. One of the most personal doctors I've seen"
