There are many people who have made this book possible both recently and in the past. I thank my husband, children, and family for their constant loving support throughout my professorial career. I thank numerous colleagues who have commented on and critiqued my work on the Medicare program, administrative law, and health law and policy over the years. Several people warrant specific mention, Eric Meslin of Indiana University Center for Bioethics; Eric Wright now of Georgia State University, my colleague for twenty years at Indiana University’s Hall Center for Law and Health; Dr. David Orentlicher; Dr. Jeffrey Rivett, the famed historian of the National Health Service; Dr. John Clark of Indiana University Health; Bernard Dickens of the University of Toronto; Fran Miller of Boston University; and my colleagues and friends at Southern Illinois University and at the Beasley Institute for Law and Health Policy at Loyola University of Chicago School of Law. Many people helped me produce this book including my research assistants over the years and, in particularly, Allison Potenza, who worked with me most recently. I also want to thank Faith Long at Indiana University for proofreading and preparing the book for publication. I want to give special thanks to Miriam Murphy, the librarian at Indiana University McKinney School of Law, who found sources from here and abroad. I also want to thank my colleagues at Cambridge University Press who did such a great job preparing the book for publication. Finally, I would like to thank my students at Loyola University Chicago School of Law, Southern Illinois School of Law, and Indiana University McKinney School of Law, who challenged and enhanced my understanding of the Affordable Care Act and the Medicare program as well as reading and commenting on chapters of my book that had been their text. I am grateful.
