I’m Charles Junior Castillo, MS and I’m an Exercise Physiologist.

I work with individuals regardless of age, ability, and condition. I am also an instructor in the Kinesiology Department at Holy Names University and San Francisco State University.

My experience includes working in the Black Forest region of Germany as a Physiotherapist and Sport Scientist. I provided Sports & Conditioning Programs for soccer players and did hands-on work in manual therapy and cardiac rehabilitation.

In addition, I have been a Master Trainer and Fitness Manager in multiple gyms. I hold a Masters of Science in Kinesiology from San Francisco State University and have been working in my field for 8+ years.

Fun fact: I am also a proud father of Pacha und Klaus, my twin German Shepherds.

Exercise physiology means the identification of physiological mechanisms underlying physical activity, the comprehensive delivery of treatment services concerned with the analysis, improvement, and maintenance of health and fitness, rehabilitation of heart disease and other chronic diseases and/or disabilities, and the professional guidance and counsel of athletes and others interested in athletics, sports training, and human adaptability to acute and chronic exercise.
