I've been on the fence between getting into the PGA program, or going through the TGM teacher training. It took 3 minutes and 50seconds of seeing TGM in action to make it brutally clear which direction I should go.
I can't even begin to describe how superior that was to the numerous lessons I've observed from PGA professionals. TGM in action is a beautiful thing.
