Currently a senior at Harvard University, Jackson is concentrating in Government with secondary fields in Russian Language and Russia, Eastern Europe, and Central Asia Studies.

Jackson’s passion for human performance began during his time at the Home Base Intensive Clinical Program and Comprehensive Brain Health and Trauma Program in Boston, MA. This experience introduced him to holistic health and wellness, shaping his belief that raw physical performance is only a fraction of what it takes to achieve lasting health and longevity.
