"Dr. Rufner helped confirm a diagnosis for me after experiencing mystery symptoms for over two years. I felt like my concerns were taken seriously at this clinic and I am very thankful and actively working on symptom management. As part of my diagnosis I had an endoscopy at their procedure center and it went very smoothly there as well."

"Dr. Rufner was extremely easy to talk with. He used language that was easily understood. I was asked several times if I understood what he was telling me and was asked if I had questions. I look forward to meeting him in person."
