Owner/Head Coach, CrossFit Level 2 Trainer

After graduating from NC State in 2007 I worked as a personal trainer and obtained multiple certifications before becoming exposed to CrossFit in 2008. I delved as deep as I could into CrossFit, learning as an athlete and refining my coaching techniques working as a trainer for 4 years. In 2011 I became a coach at CrossFit Raleigh. Later in 2011 I joined the US Army National Guard and commissioned as a Second Lieutenant after completing Basic Combat Training and Officer Candidate School in Ft Benning, GA. Upon returning to North Carolina I became an ownership partner and full time coach at CrossFit Invoke until 2014 when I opened CrossFit Goliath.

First CrossFit Experience

The 300 workout from the movie 300 exposed me to the type of training. My dad and his law enforcement buddies told me about CrossFit and I tried a modified version of Barbara thinking it would be easy. I was wrong. My first true CrossFit workout was with my training partner and colleague, now owner of CrossFit Zeal, Mike Kelley. It was in August of 2008 and it was a 20 min AMRAP of 15 Pull Ups, 30 Push Ups and 45 squats. We both ended with 4 rounds exactly and were hooked from then on. My first Fran took me 7:10. I laid on the floor for 23 more minutes then had to go back to work.

Favorite Lift/WOD, Favorite Coaching Moment

I love Clean and Jerks. There is just something so powerful about the movement. My favorite coaching moment is the first time a female athlete gets an unassisted pull up. Most often they join the gym not believing they could ever do a pull up and are usually so thrilled. Doing something you couldn’t do before or didn’t think you could do happens a lot in CrossFit with good coaching, but changing someone’s belief about themselves is powerful stuff.
