I decided to check out this box while I was in town. I have been twice and will be going again tomorrow. I must say that I was extremely impressed with Derek. I have been doing crossfit for 8 months and I am still learning every day. I have an awesome box back home so I didn't know what to expect. Derek was very attentive to everyone in the class including myself, he even went on to suggest some advice to improve my DU's and power cleans that actually worked. I can't speak about the other staff but I would definitely recommend this box to anyone whether they're starting out or dropping in from out of town.
