"I had a wonderful experience! He took my concerns seriously, answered any question I had with sincerity and knowledge, and helped me understand how to manage my issues without shame or guilt. He was responsive, knowledgeable, honest, and overall very attentive. I always have a ton of questions for my doctors and he never made me feel rushed or bad for asking. Definitely recommend!"
"Fantastic doctor. Actually helps you understand things and is very nice guy. 10/10 recommend"
"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!"
"Dr. Rufner and his staff are always prompt, professional and pleasant. The subject matter when seeing an Gastroenterologist is not the easiest to discuss and yet Dr. Rufner has the natural ability to put the patient at ease when discussing symptoms, diagnoses and treatments. I recommend him without any reservations."
"My recent procedure performed by Dr. Trouillot was excellent and all ways. It went very smoothly and left nothing but positive impressions."
"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"
"Very pleasant visit. The steps to diagnose my condition were explained to me and I felt quite comfortable with this doctor."
"Dr. Brenner was professional and kind. She took plenty of time to talk through my symptoms and took the situation very seriously. I really appreciate her ability to think beyond just GI possibilities, and her commitment to figuring out what's wrong with me. I am so appreciative!"
"Dr. Rufner and the women were very helpful."
"I loved Dr. Brenner! She’s knowledgeable, focused, willing to listen, very straight forward (I like that) and caring. She’s down to earth, no beating around the bush, explains everything till you’re confident you understand. The office was very efficient in getting procedures scheduled, gave clear, written instructions, and answered all my questions."
