I can't find much. It seems like PA, particularly in your part of it, is full of McDojos advertising "karate for fitness and self-defense. Please inquire about holding your child's birthday party at our dojo", etc.
Here's a list of schools in PA -- maybe something will spark your interest and be a little closer than the one you mentioned. There are at least a couple that offer jiu-jitsu, and one in Turtle Creek that's actual MMA.
Good luck.
