An excellent teacher, information presented in the most efficient, organized way that keeps your attention; is fairly detailed but at the same time, easy for the lay person to grasp. If he says ‘do this, don’t do that’ he explains why. He’s science-based, and balanced with great warmth and a great sense of humour. He’s helping a LOT of people; when he starts helping you, you’ll probably fall in love with him, as my family has!
