In 1997, Cristin began her training with a focus on self-defense and fitness. As she observed the profound impact of Sealy Karate Schools' programs on her son, her commitment deepened, leading her to earn Sandan (3rd Degree) rank and become an instructor. Since 2001, she has completed numerous courses in fitness, healthy lifestyle & nutrition, as well as coaching individuals with disabilities. Beyond Martial Arts, she has achieved success as a fitness competitor, and currently represents team Girls Get Gritty in cycling.
