About Us

“CrossFit 781 is a family. We are unique and diverse, but all-inclusive.

CrossFit 781 is a place where everybody knows your name.”

– Jason & Danielle Brown, CF 781 Founders


Before we opened this gym, we created the 781 manifesto. A single sheet of paper that defined what 781 was about, what we believed in, and what our goals were. This is what we wrote:

CrossFit 781 is a family. We are unique and diverse, but all-inclusive. CrossFit 781 is a place where everybody knows your name.

We believe in having fun. Exercise needs to be different every day and present new and fun challenges. We believe this creates a true sense of accomplishment and confidence.

We believe in mastering the basics. We believe that building a foundation of knowledge and proper movement is a cornerstone of improvement.

We believe in always being a student of both life and of CrossFit. You can’t progress forward if you think you’re done learning.  We are here to learn from CrossFit and each one of our members, day after day.
