Jeff Hayes commented about him as a teacher in this 2005 post:

Although he has a very kindly and unassuming manner, I was immediately thunderstruck by both the depth and breadth of the knowledge and insight be brings to bear on the practice of painting and drawing. In the space of just a few sentences, he would touch on physics, anatomy, geometry, optics, engineering, art history, pedogogy, physiology, materials, perception, oh, and philosophy to boot. And these were not the abstracted mental meanderings of a scattered intellectual. Rather, all his comments had direct relevance to the subject at hand, which is to say aspects of drawing the human body. It was really a virtuoso performance, indicitive of a lifetime spent deeply pondering the problems of making art.
