Ron’s interest in health and fitness started when he was a student athlete in high school. He participated in various athletic activities such as football, baseball, basketball, soccer. His interest and passion continued into his college career, which led Ron to pursue his education in the study of sport and exercise and mechanics of human body movement. Ron understands that strength training and movement are essential, however, he believes the exercises each individual performs should imitate daily, ‘real-life’ activities such as squatting, bending, twisting, pushing, and pulling; also known as “functional” exercises. Moreover, he believes one must also have a strong understanding about the nutrition component to health, fitness, and performance. Ron has 20 years of experience in the fitness industry and has taught group fitness and bootcamps in San Francisco, Daly City, Burlingame, Belmont, San Carlos, Redwood City, Menlo Park, Palo Alto, and Los Altos Hills. He has more than five years of coaching experience in basketball, baseball, and football at the youth, high school, and college levels. He was the first Athletic Conditioning Specialist and advisor for the SF Warriors Football and Cheer; and formerly the Strength & Conditioning Coach for College of San Mateo Baseball (2011 – 2013 Season). Ron’s goal is to promote health and life-long fitness and wellness, and encourage prevention of illness and injury. "Be Passionate. Have Fun. Live Life."
