Gabrielle Newmark

As a member of the University of Oregon Rowing Team, Gabrielle first realized her athletic abilities.

Ever since, she has worked to refine and learn new techniques, and to best understand an opponent through sparring. Her passion for the combat sport led to her pilgrimage to its place of origin -Thailand- where she trained at camps in Chiang Mai and in the hillsides further North. Today, Gabrielle continues her love of Muay Thai as a student, teacher and trainer.
