What Our Patients Are Saying

The staff at the Digestive Health Institute | Gastroenterology is a remarkable group of people. Let’s be honest, nobody looks forward to seeing a gastroenterologist, so when the staff at a medical practice—the ENTIRE staff—is kind and helpful, patients are going to feel more comfortable being there. That is the hallmark of patient-centered care, and it’s what I experienced at the Digestive Health Institute | Gastroenterology. The intake person at the front desk was pleasant, helpful and efficient. I was struggling with my allergies and needed water, and after directing me to the water fountain, he offered me a cup. While that’s a small gesture, it demonstrated real consideration. My medical history was taken by a staff member who was engaging and friendly. I saw a medical resident who spoke with me about why I was there. I gave her some of my history, and then I saw Jannel Lee-Allen. Dr. Lee-Allen has a remarkably good bedside manner. She showed concern while at the same time being direct. Hearing things that are potentially unpleasant are sometimes best said in a direct way, and I value that. Dr. Lee-Allen was clear and concise and direct, but her clarity was infused with a sense of humor. Again, that’s putting a patient at ease. I had to schedule a procedure, and that involved spending a lot of time with the scheduler. She took the time I needed. I never felt rushed. The time it took was based not on her getting to the next patient. It was about what I needed and making sure I understood everything about preparation for an upcoming procedure. I struggled to understand some things, and I needed her to go over them several times. The scheduler, however, was reassuring, telling me she would take the time necessary. She wanted to make sure I understood what was happening. This is another example of how the Digestive Health Institute | Gastroenterology believes in patient-centered care—something they demonstrated that every step of the way.

Dr. Hiatt listened to me. He was very thorough in his explanations and didn't talk down to me. It was very difficult just finding a gastroenterologist and he was very knowledgeable and sensitive.
