Casey Hall (Coach)


Casey grew up with an athlete mentality, playing football and baseball. Both CrossFit and MMA training helped him through high school. Sense then, he’s never stopped learning everything he can about health and fitness. His goal is to help people use fitness to be the best version of themselves, as fitness helped mold him into who he is.

“The struggle itself towards the heights is enough to fill a man’s heart. One must imagine Sisyphus happy.”

Jordan Springer (Coach)


Jordan credits CrossFit to a lot of wonderful life lessons. Struggling with depression and suicide as a young teen, she found CrossFit to be a constructive use of her energy, finding passion in building not only physical strength but mental fortitude. Coaching and learning throughout her high school years, she got her L-1 upon graduation, opened her own gym in her Georgia hometown, and enjoyed weightlifting for the next couple years. Almost 10 years later, she’s joined us out here in Washington. If she’s not at the gym, you can find her getting lost in the mountains with her german shepherd.

“CrossFit is medicine for the mind, body and soul.”
