Meet Our Doctor
Dr. James Davis is a triple-board certified physician in internal, pulmonary, and sleep medicine. After training in some of the coldest places in the country, he is back home in Arizona, where he opened the Twilight Clinic to specialize in pulmonary and sleep medicine. Dr. Davis approaches breathing and sleep issues holistically and wants his patients to have a unique and satisfying experience.
Dr. Davis practices enjoys living a healthy lifestyle. He does weight and cardiovascular training four to five times per week and loves the outdoors, including skiing and hiking. He is also an avid reader.
Dr. Davis bought his first house and has had to learn the art of interior design. Part of his decorating includes his obsession with plants, now that he has learned how to keep them alive.
