Just started a couple weeks ago.. they make you feel so comfortable and confident.. everyone goes at their own pace and the vibes are unmatched. The only time I've ever enjoyed going to workout.

I went to my first class in November 2022 at the encouragement of my husband. He'd been trying to get me to go for several years, but I felt too intimidated and insisted CrossFit couldn't possibly be for me. It's unfortunate I thought that, because I was absolutely missing out. The community here is incredibly supportive and friendly. Everyone is working to better themselves and your personal successes are celebrated by everyone. The coaches are excellent and very helpful when it comes to scaling the workout to make it work for individuals (and they answer my numerous questions!). An absolute gem of a gym.
