A really good Alexander teacher.
Mark Josefsberg is the Alexander teacher I would recommend to anyone interested in learning the Technique, at whatever level. Mark is kind, knowledgeable and gentle, and teaches the Technique in a non-gimmicky way that is highly effective. As soon as I'd had my first lesson (free), I knew I would be coming back. I've just lesson #22, and it seems my backaches are a thing of the past!
