"Make sure you bring a mask (unless you're reading this from a post-pandemic world in which case, don't rub it in), I forgot mine and almost had to miss my appointment because of it. Luckily there are nice dentists next door with masks to spare."

"Dr Ruffner is a very informed and progressive physician who relies on his education, experience and collaboration with others to be effective for his patients. He has been the only physician who didn’t quickly dismiss my digestive issues as IBS and truly explored deeper which paid off. He listens and takes his time to respond and explain. You will never feel rushed. In the past I’ve had issues with inept administrative and assistant staff but so glad to have NeeNee as the face of this practice. She’s personable and pleasant to work with."

"Dr. Rufner was very knowledgeable and answered all my questions I had before I could even ask them. The prompt response and fast scheduling from them made my experience here way better than the last Gastroenterologist I was at."

"Dr Brenner is the BEST--very well qualified as a gastroenterologist. Her bedside manner is so caring and an excellent listener who provides the best care possible--IBS seems to be the "in" disease and she is most sympathetic in handling issues surrounding IBS and providing answers and remedies ""
