Onyx Combat Sports

This gym is the best gym I have been to in the Philadelphia and mainline area. The gym has awesome people to train with and extremely welcoming to new people regardless if you have ever trained before. Zach is one of the nicest guys I have met and an extremely knowledgeable instructor. I would recommend anyone looking to start any martial art or combat sport definitely come try out the gym. You will not regret it.

If you're looking for a Martial Arts gym, then Onyx should be at the top of your list. Dan, Kalle and Zach are amazing instructors and people. They treat you with the utmost respect and care about your goals. I'm proud to call Onyx home, and everyone there Family.

Onyx is the best gym I have ever trained in!(even though its been my only one) Zach, Kevin and Kalle are all great instructors but when you're there ask for Odyn. Odyn is by far the best thing about Onyx Combat Sports!

As someone who has trained at multiple gyms over the course of many years, I will say Zach’s instructional is superior. Zach also creates an amazing culture in his gym focused on respect, growth and even having a good time, a combination you don’t see all too often in this sport. Thank you, Zach, and all the onyx members for creating my favorite space.

I have been a member at Onyx just shy of a year and Zach and Kalle are not only some of the best people I have met, but amazing coaches with a tremendous skill set. This gym builds you up and teaches you so many great techniques to become an all around mixed martial artist. The instructors are so welcoming and very helpful with any struggle or needs and can really help understand the move that is being taught. This place is a family atmosphere and everyone is very humble. Please check Onyx out for yourself!
