Our expertise

Ryan E. Little, MD, is a board-certified rhinologist and sinus/nasal specialist. He is the only fellowship-trained rhinologist/sinus surgeon in the state of New Hampshire.

Dr. Little is the director of the Sinus Research Center, which maintains active collaborations with Geisel School of Medicine at Dartmouth College's basic science laboratories. The Sinus Research Center examines microbial community dynamics in the sinuses and airways. It also participates in the latest clinical trials, so patients can gain access to new research treatments before they are widely available.
