SUPER late review but I was talking about Jiu jitsu with some training partners and I remembered having visited this place about a year and a half ago. It was a little difficult to find if you're not from the area ( nondescript building on a small side street) but once you're there you will be impressed. The facility is super spacious and very clean. The locker rooms are pretty modern and well kept. There's even a small "chill" area with some tables for the non-participating type.
The training was legit. VIGOROUS warm-ups and kick-ass training partners. Rest assured, there are no easy rolls here. I've visited BJJ gyms all over the country and this is for sure one of the best ones out there. If I ever found myself in Pittsburg for any extended amount of time, I wouldn't hesitate joining this gym. Also, Warren was a super nice guy!
