"Don Cohen has done an excellent job of presenting an overview of the various diagnostic, evaluative, and therapeutic approaches to the cranium, the sacrum, the dura matter envelope, and the fluid which it encloses. He is one of those rare individuals who has a real and true sense of the human body and what it is about. He also has a deep appreciation of the fact that the human body is not living in isolation. He knows both intellectually and intuitively about the interrelations between spirit, mind, and body."
