Although I was under the impression that I had called to schedule a colonoscopy and kept my appointment. While I was in the exam room waiting to be seen by Dr. Brenner, and when she came in the room, I was informed that the procedure would not be performed, but needed to be scheduled appropriately. Nevertheless the time that I spent talking with Dr. Brenner was very pleasant, professional, and laughable. Everyone stay tune to see if my sentiments and rating shall remain the same after the procedure. Lol 😆
Everyone was so kind and nice. The nurses and doctors were great for a quick and easy procedure. Thank you!
Dr. Rufner is by far the best gastroenterologist I’ve seen in my lifetime. With a deep understanding of the immune system and gut-immune-nervous system connection, Dr. Rufner has not only saved my life from recurrent C Diff, but also brought me a better gut-related quality of life than I’ve ever had prior to working with him. While I live with Primary Immune Deficiency, Alpha1, and other complex co-occurring medical conditions, I am now more confident in my safety and ability to handle GI-related crises if/when they arise with Dr. Rufner on my treatment team. I recommend Dr. Rufner for any GI needs, and without reservation for persons navigating chronic illness needing a GI consult. I owe my life to Dr. Rufner and his team, and couldn’t be more grateful for their help!
Dr. Jennifer Brenner is a compassionate professional who listens with empathy and kindness. I feel lucky to be treated by her.
Dr. Trouillot is through, caring and efficient.
I have been a patient of Dr. Trouillot for many years. He diagnosed a genetic disorder that had it been undiagnosed, could have led to more serious issues. I have great trust in him and his expertise as a G.I. doctor. He listens well and is caring.
Nice place. Helpful staff. Great doctor.
Very professional and efficient. One suggestion: Have milk to accompany cookies. Healthier and cheaper than soda pop, and goes better with cookies.
Since I walked in everyone was every nice and attentive, had a very good experiences. Dr Trouillot is a great dr. explained everything and very thorough, I would recommend him to family and friends. Thank you Dr. Trouillot
Staff and physician were professional in every way and communicated well.
Always timely and great staff, very friendly! Dr. Brenner is great and doesn’t rush you, very knowledgeable and caring.
The whole experience was really new for me, but everyone here made it as pleasant as possible. The waiting room was welcoming, and the people were awesome. Considering all their patients are hangry when they show up, the level of service is amazing. They even gave me cookies after, how would you not like cookies?
Best GI doctor I have ever seen, he took the time to explain things to me and then we came up with a plan, feeling very hopeful, finally!
Dr. Brenner is a brilliant professional medical doctor! Extremely caring & professional. I trust her with my life!!
Dr Kevin Ruffner is a Genius. I had to see two PCP Doctors and two ER doctors that couldn't figure out what was going on with me. I saw Dr Kevin Ruffner for 3 seconds and he knew exactly what was going on. Very smart genius and extremely kind. All of the staff are wonderful people. I love this place.
Dr. Rufner is an amazing doctor, Every time I see him he takes the time to listen and ask questions. He always explains everything in detail that helps you know what is going on and the details of what he wants you to do. He’s the best.
The people in the office were great. The dr and nurses and the anesthesiologist all made you feel comfortable. The care was great. Everything went well. Thank you all
It was truly the most pleasant experience one could expect from a colonoscopy.
I was very pleased with my appointment with Dr. Brenner. This was a followup appointment and she was very attentive to my questions, and responsive to my concerns.
Great! Very concerned and caring doctor.
