Sean Spangler's style of instruction is clear and concise, and he has a talent for finding just the right tweek you need to make his techniques work for you. The material presented is powerful, and more importantly it really flows together well. Sean has an amazing ability to present in such a way that helps you see the "bigger picture." The teaching methods are also innovative. A strong emphasis is placed on drilling, to build body memory, and continuity, so you can actually make what you learn work on the mat when you go live. The facility is more than adequate, with plenty of matspace to roll. Schedule wise, absolutely the best value in the Triangle, with multiple classes most days(so even if you're busy with work and family, you've got no excuses not to train;)). And perhaps most importantly, the community being built around this school is filled with fantastic, supportive and friendly individuals, all working to be their personal best while building each other up in the process. Very family friendly as well, with kids classes several times a week. All and all, a huge boon to the community.
