Kelly Tang has been a student with CU Jiu Jitsu since its inception in 2018. She has now been actively training BJJ for over three years and is currently a purple belt. In 2020 Kelly also started training kickboxing and Muay Thai, adding stand-up combat techniques to her martial arts arsenal. 

Kelly is a volunteer coach and mentor for new white belts, especially for women who have no prior martial arts background. She is passionate about getting more women involved in BJJ and kickboxing because she believes that it has given her an immense confidence boost, changing her outlook on life from "I'm scared" to "I can handle this." 


Outside of the gym, Kelly enjoys a wide variety of hobbies and interests, including: camping and hiking, travelling, food, video games, and watching trashy reality TV.

Why Choose CU Jiu Jitsu?

An Environment For Everyone

We believe what sets us apart from other schools in town is our dedication to building a positive environment focused on inclusivity. We are the only school in town that consistently holds women-only classes because we believe that it is important to provide a dedicated and safe space for women who are not yet comfortable grappling with men. 

Additionally, we stand firm in our belief that martial arts should accessible for everyone, regardless of age, gender-identity, sexual orientation, religion, or body size/physical capabilities. Our goal is to provide a welcome environment that everyone can be comfortable in.

Social Events Outside The Gym

​We organize monthly school events like trips to amusement parks, movie theater outings, cookouts, float trips, camping, bouldering, team dinners, and more. Not only does this allow our members to know each other outside of the gym, we also enjoy supporting other local small businesses. We strive to foster and build lifelong connections because we recognize the importance of having a strong community. 

No Egos Allowed

Respect is one of our core values. We don't tolerate ego-training here, which leads to a lack of respect for others and increases risks of injuries. We encourage healthy competitiveness in our athletes, but at the end of the day we lift ourselves up by lifting those around us, not by tearing them down.
