Our Values
Integrity
We are only as good as our word; if we say we are going to do something, we do it. We set standards for our athletes and ourselves and we uphold those standards with integrity.
Honesty
We say what we mean and are open and honest with our athletes and clients. If we don’t know the answer to a question, we will say so.
Care and Concern
We care about each and everyone of our clients. When we ask “how was your weekend” or “how is your father” or “how did you sleep” we ask with genuine care and concern. We care about the whole person, not just the workout.
Inclusivity
As is enumerated in our Zero Tolerance policy, we do not tolerate exclusion or hate of any kind. We strive to be a culture where everyone is and feels welcome, regardless of gender, race, sexual orientation or physical ability.
