Get the Sleep You Deserve

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 patterns. Dr. Davis approaches breathing and sleep issues holistically and wants his patients to have a unique and satisfying experience. 

Dr. Davis practices what he preaches to his patients by 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 who tries to read at least two books each month.

Dr. Davis recently 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. In his younger days, he was a musician— playing the piano, violin, and cello. Speaking of music, his all-time favorite is music from the 80s.
