About Us

Why Sempiternal?
Sempiternal is Latin, meaning always (Semper) and eternal (aeternus).
The love we have for CrossFit is Sempiternal, and so is the passion we have for helping others. There is no other feeling quite like achieving something you once thought impossible. Your first muscle up, your first bodyweight clean, your first double bodyweight back squat, it’s all achievable with the right coaching and motivation. CrossFit Sempiternal is a place you can go at the end of a bad day and turn it into a great day. It’s a place where everybody knows your name, knows your children’s names, your likes and dislikes. CrossFit Sempiternal is a home away from home. We want you to share our Sempiternal love for CrossFit. Join today!
