"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."
