Meet the Director
Jonathan Demcak
Director of operations | lead performance specialist
Jonathan is a Sun Prairie, Wisconsin native whose lifelong involvement in sports—especially basketball—shaped his passion for human performance. After competing in basketball at both the high school and collegiate levels, he entered college unsure of his career direction, ultimately earning a degree in sociology driven by his desire to help people.
Jonathan’s interest in strength training accelerated following his final season of college basketball. He devoted his free time to learning more about the science and application of training, laying the foundation for his future in the field. After exploring a few career paths post-graduation, he found his calling in health and fitness, spending three years as a personal trainer. During this time, his expertise and passion for performance development continued to grow.
Seeking to further specialize, Jonathan joined ETS as a full-time performance coach, where he spent several years refining his coaching skills and deepening his impact on athletes. When the opportunity arose to return home to Wisconsin from Minnesota, he embraced it with enthusiasm.
Jonathan is driven by the desire to be the coach he wishes he had growing up—someone deeply committed to athlete development, mentorship, and performance. He is proud to bring that level of dedication to the athletes he now trains and guides.
