Originally from Vermont, where I spent most days as youth outdoors in the mountains hiking and camping. I ran track and field in high school, and then enlisted into the Marine Corps immediately after graduation. I spent 20 years on active duty where I was a martial arts instructor trainer, Marine Corps Drill Instructor, subject matter expert for combat conditioning, and ultimately fell in love with endurance sports. I found a Obstacle Course Racing was very similar to what we did in the Marine Corps, just a little easier and less danger involved. For a few years I raced various distances from 5k and little mud runs to Marathons, utlra-races, and Worlds Toughest Mudder. Ultimately, as I was finishing my degree in dietetics I found triathlon and was hooked. As a new triathlete I raced at the USAT Age Group National Championships in 2016 and 2017 and various other distances. I retired from the U.S. Marine Corps in 2017 to pursue my masters degree in health communications and complete my dietetic internship to become a Registered Dietitian. While I was active duty I coach and trained hundreds of athletes in endurance sports and martial arts, I made my transition to coaching triathletes as I retired from active duty. Now I am own and operate Top Nutrition and Performance, a veteran owned business located in O'Fallon, Illinois that specializes in evidence-based nutrition counseling and sports performance coaching.
