I've dropped in a couple times to make sure my training stays on track while visiting from out of town. The General feel of the gym was warm and welcoming. There was a class going on while I did my own training. The coach, Meghan, was very kind and from what I could see she was very attentive to her athletes. I made sure to stay in my general area and out of the way. Meghan made me feel comfortable as well as all the athletes. This facility is a good size and has everything you would expect a Crossfit box to have. They have a good size room for the children to play. The atmosphere was also welcoming to little ones in the gym area. It was good to see such a family environment. I will definitely be back and will be buying a punch card for future visits. read more

We also have two garage doors that help with air flow on hot days and during tough workouts!
