I know nothing beyond just reading their website, but I'd be willing to support them by attending a class. I'd have my expectations set VERY low. Even if the guy is a rock star, you're probably only going to go as fast as the rest of the class, which i'd wager is quite slow.
judging from the pictures, standing at what looked to be 5-7 yards, one person in a line of 8 is squared up on the gun, while everyone else is very bladed. prone photos are similar. no one in the sitting photo has a decent position, and 1 person in the kneeling photo might have bone support. this is somewhat surprising since he lists appleseed expert rifleman in his qualifications.
when the class description lists "team movements, Small Unit Tactics, leadership, communication, CQB, raids, ambushes, react to contact drills" and the rest of the class are obviously new shooters, I'd be pretty hesitant to do non-square range stuff for safety reasons
