Pearlyn Tomosie, MD

Family Physician

Pearlyn Tomosie, MD, the first known Hopi physician, is medical board certified in Arizona and New Mexico, BLS/PALS/ACLS certified, and a proud NAU Lumberjack Alumni. Dr. Tomosie sees patients of all ages and backgrounds, but especially enjoys focusing on Women’s Health and pediatric/adolescent visits.

Dr. Tomosie grew up on a small reservation in Arizona with a goal to practice medicine in a small, rural, clinic setting while working primarily with underserved minorities.
