To my wife Penny who, in her desire to avoid public attention, goes otherwise unrecognized. As a Psychologist, deeply committed to her craft, her breadth and depth of knowledge continues to astound me and is woven through these words. Your faith in me sustains me. I am also deeply indebted to my clientele. As a medical student I was told they would be my greatest teachers. At the time I did not begin to appreciate the fullness of the gift coming my way.
