"I get really good attention and am listened to. When I call with a question, I get a follow up call back. I had labs drown and Dr. Brenner called me herself to tell me that they were normal. Often times a normal result has not been call personally by the treating physician. It is here. I’m impressed and I’ve had IBS for over 30 years now. So, that’s saying a lot"

"Thanks to Dr Brenner my colonoscopy was amazing! The anesthesiologist was helpful and amazing also! I would recommend this office to anyone that has to have a colonoscopy. The entire staff was 10 Stars if that's a good rating... 20 stars is better! Thank you! G.Terry"

"Procedure was professional. But even tho I followed the prep directions to a T, my system was not fully prepped for the colonoscopy. Therefore, the doctor couldn’t see much of my colon. I continued to have diarrhea for four more days. Also, the first nurse couldn’t insert one, and then two blood ports in my right hand, the second nurse installed a port successfully on my left hand on the first try. It was a difficult day, made more difficult by these near misses."

5.0 Review from M.K. Source: Google Dec 25 2022

"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 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"

"Dr. Brenner is the best! In a telehealth appointment today, we reviewed my past medical history, discussed a new diagnosis and her continuing role in my care with respect to the diagnosis, she developed a plan and goals for the next six months, ordered a new prescription for me and requested copies of some recent studies - all in short order. I have always found Dr. Brenner to be knowledgeable, honest and well-prepared. I am privileged to have been her patient for many years and will continue to be her patient as long as she will have me!!"
