To Rachel and my girls, Talia, Jessica, and Naomi: your support means so much and I love you. To Dr. Berrigan, and the faculty and residents at GW: you inspire me each day to find new ways to improve, both programmatically and personally. Thank you for the encouragement, and the high standard that you set on a daily basis. And to Dr. Freeman: I cannot imagine a better coauthor, program director colleague, or friend. (JB)
