"Getting to know what is important to you as my patient – that’s at the heart of my work. It’s the most important part of my day-to-day efforts, because getting to know you will help me provide you with the best possible care."

About Me

Ryan J. Miller, MD, is an internal medicine physician with Avera Medical Group Internal Medicine.

Dr. Miller enjoys how the care team comes together to help each patient, with a focus on communication in both clinic and hospital settings to make sure the best possible outcomes are reached every time. The wide range of cases in his specialty leads to many different approaches, from coordinating care of patients with complex conditions like lung conditions, heart disease or diabetes, but also providing routine care to other patients, especially in older adults.

He has a special passion for quality and has completed a number of research projects that focus on including a quality focus on all aspects of health care. His training and experience help him to solve puzzling diagnostic problems you might face, and he can handle severe chronic illnesses and situations where several different illnesses may strike at the same time.

He worked in an Avera emergency department when he was younger, and that exposure to care in urgent settings led him to a medical career. He feels at home with Avera because of its focus on patients at the center of all care decisions and the compassion of every member of the team.

Active Lifestyle

When he’s not seeing patients, Dr. Miller loves to spend time with family outdoors, hiking, biking, kayaking or playing golf. As a Sioux Falls native, he and his wife are thrilled to plant roots here with their children.
