Had a quick trip to KoP for my work and shot them a last minute message about dropping in. Chris responded to me within the hour! I attended the no gi mixed class Dylan led and got to work with some super technical and friendly people. Really enjoyed this gym and would recommend it to anyone looking to gain every last drop of knowledge. If I find my way back up near KoP I know where I will drop by again!

Precision Jui-Jitsu in King of Prussia is excellent all around. They are welcoming to beginners and they have very experienced black belts that can teach anyone at any level. There is a full schedule of classes, great communication, the gym is very clean, and there is a great vibe with a lot of individual instruction. It’s the real deal. As an older beginner, I’ve had a great experience there. I would highly recommend to anyone, five stars all around. ⭐️⭐️⭐️⭐️⭐️ 👊

My 3 kids were enjoying learning, however they had been bullied multiple times, by the sons of one of the owners. During their first tournament, my son went up against one of the boys, and won. The older boy, was screaming instructions to his brother to elbow my son in the face. My son still won. The older brother 13, went up behind my 7 year old, threw him in the air, and let him land on his arm, hurting his arm. When I told the owners, I was told that it was "just rough housing" and that I should have been watching my kids, as though it was my 7 year old's fault for standing. I am completely surprised and utterly disgusted that they allow bullying, and that there was no repercussions for the 13 year old picking up, throwing, and hurting my child when his back was turned.
