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.
