Keith wears Carhartts instead of black t-shirts, but he is an artist. He knows concrete, but also so much more. Not only the aesthetic design, but the practicalities of making something work, and for the long term. His course is hands-on and practical, and small enough that he can deal one on one with each student; he is straight-up and honest, and genuinely cares that each person really learns and can demonstrate their new skills. I would recommend Keith to anyone wanting to learn about concrete.
