Get To Know Diana


What is your favorite place that your journeys have taken you to so far & why?

My greatest love is Southeast Asia. I first travelled there when I was 19 and spent some time living in Vietnam and Thailand. Bangkok is just the coolest city. The Thai islands are amazing too, and they have really developed as sports destinations in the past few years, especially for Crossfit. My ideal is always somewhere I can do my sports and be part of the community!
