I dont think anyone could go wrong with lessons from Gary, just listen to his playing!
Of course, many can play well but not all can teach. Understanding what a person needs at a particular part of their development as a musician is what Gary can help you with. He has a very calm and measured approach to then getting you on your way without being overwhelmed. The advice on how to optimise your practice is also laid out by Gary and the approach is rooted in what neuroscience currently recommends.
If you're on the fence, don't 2nd guess, get stuck in :)

Great Lesson
