Nate Kuffrey – Owner and Head Coach 

I began my fitness journey as a life long athlete all the way through college where I played football for Assumption College in Worcester Massachusetts. This is where I first experienced my passion for fitness, but never thought it could turn into a career.

I graduated with a double major in Biology with a concentration in developmental physiology and Marketing. 

CrossFit Came into my life in 2011 right after finishing college, my friends pressured me to try it saying I would love it. They were right I was hooked. The combination of all the different elements got me in the best shape of my life. From that point on I began competing and learning as much as I could!

CrossFit to me is much more than just helping people become more “fit”, it is a way for a community of individuals can have fun, compete, help each other, and get better everyday.
I look forward to helping you all!
