To Mom and Dad. You taught me how to change the world to make it a better place,
one patient at a time, and more globally through theory and research.
To my children, Alyssa, Dylan and Rachel. I am so proud of all three of you and the
paths that you are forging. I am confident that each of you will make
the world a better place in your own way.
Most of all, to my wife Nancy, Thank you for your understanding and compassion.
Your unwavering support has made this book possible. You make me, and
everyone who knows you, a better person.
