Jackson Sinnott is an O2X instructor who grew up in Duxbury, MA. He enlisted in the Army in 2014 and served seven years in the 1st Battalion, 75th Ranger Regiment. Following his active-duty service, he transitioned to the Massachusetts National Guard, where he now serves as a State Marksmanship Instructor. 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.
Outside of academics and his military career, Jackson enjoys reading, golfing, and competing in USPSA shooting events. With a commitment to pushing his limits, he hopes to complete an ultra-marathon endurance event in 2025.
