"Dr Sieja found colorectal cancer on my very first colonoscopy. His care and professionalism supported me through the experience and to a manageable lifestyle to this day."
"Gave all the time I needed to ask my questions and gave clear concise Information."
"Dr. Rufner is the BEST! He took a lot of time during my appointment to explain my G.I. issues and devised a plan for treatment and further testing. I found him to be patient, caring, knowledgeable, and thorough. I highly recommend him for any G.I. issues. He is far and above other G.I. doctors, I have seen in the past."
"Dr. Trouillot is a very knowledgeable doctor with a caring professional bedside manner. He listened to everything I had to say and made me feel comfortable talking about gastrointestinal issues. He made me feel like we would find out what was wrong with me, and did not, at any time, make me feel “gaslighted”. I would recommend him without any reservations to anyone needing to see a gastroenterologist."
"Personable, Knowledgeable, Understanding, and informative."
"Good first visit"
"Friendly staff, Thomas was very fast but thourough, and I was also recomended by a family member who had a good experience."
"Dr. Brenner is a very caring doctor who actually listens to you!"
"I have been a patient of Dr Trouillot for many years. He has always been attentive and open to answering all my questions and concerns. His care has resulted in total remission of my UC. I could not be more satisfied with his his care and the service provided by his staff."
"Dr. Brenner has been so helpful. My discomfort has been addressed and I feel so much better. Wish I would have found her years ago."
"It was a great & wonderful experience, my appointment with doctor Kevin Sieja, M,D was totally awesome, I'm looking forward to my next appointment at ease. and the staff just wonderful."
"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!"
"Dr. Rufner also knows some Spanish, which helped out to explain my dads situation. And I definitely referrer him to my family and friends to his office. Thank you for your great services!"
"Dr. Rufner not only provided great care but I left feeling hope for the first time in years. He takes the time to listen and answer all questions and I never once felt rushed. While I’m still going through my care plan with him, just leaving with hope is enough for me to recommend him."
"Dr. Rufner is the best physician I have had in my lifetime. He will listen, and address your issues with clarity. There just aren’t enough stars."
"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 Brenner had good advice for me. And she was nice."
"I just had my first consultation appointment with Dr Trouillot. What I found most valuable about him was his attentiveness, a great listener. Too many physicians are pressed for time and are challenged with allowing patients to explain their symptoms and history in detail. Dr Trouillot gave me the time to explain and I never felt rushed or dismissed."
"I have gone to Dr. Brenner for years and she is great. I would recomend her to a friend."
"Dr Brenner is very professional and always addresses all my concerns. I would highly recommend her!"
"Dr Brenner was very thorough, explain everything in detail. I was very pleased and happy with her. Glad to have her as my especialist."
"I was referred to Dr Brenner by my PCP for a consultation regarding ongoing gastrointestinal issues. I was impressed that she had taken time (before my appointment) to read over several years of medical notes from my previous doctors. Dr Brenner listened well and did not rush through our visit . I found her to be knowledgeable, empathetic and helpful in deciding on an action plan."
"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 was thorough. I didnt feel rushed. Answered all my questions."

"Dr. Trouillot was very knowledgeable and spent a lot of time during my initial appointment. He added me on to his busy schedule for an upper and lower scope in two days. Dr. Trouillot followed up with biopsy results within one week and took time to explain results and plan of care. Having been a nurse for thirty years and having worked GI I think he is a exceptional physician. I am very impressed with his care."

"i felt that when I was there 2 yrs, ago I felt that Dr. S. was more patient and listened more.{perhaps he did not like the fact that I turned down the coloscopy.) I question why I have to have invasive procedures when less alternatives have not been explored. They own the center. Caching, caching.... $$$$$$$$$$$$$$$$$$"

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.
