In addition, he is the author of the book “The Myth of Choice,” published in 2011 from Yale University Press, Prunsoop Publishing (in Korean), and BiteBack Publishing (UK). Kirkus Reviews stated in its review: “The author deftly debunks prevailing dogma about the infallibility of free markets, especially important during a time when, as he reports, one in seven Americans are poor." He is also the author of the book “The Failure of Corporate Law” published by University of Chicago Press. The book has been called “simply the best and most well-reasoned progressive critique of corporate law yet written,” and the Law and Politics Book Review said that “it merits a place alongside Berle and Means, [and] Easterbrook and Fischel.”
Greenfield also has had journal articles published in the Yale Law Journal, the Virginia Law Review, the Boston College Law Review, the George Washington Law Review, and the Tulane Law Review, among others. His articles are widely cited, and he has been called “the leading figure” and “the most creative thinker” in the progressive, stakeholder school of corporate law scholarship.

Greenfield was named B.C. Law Teacher of the Year for 2003-04, a recognition bestowed by the Law Students Association on vote of the entire student body. He was also awarded the Emil Slizewski Award for outstanding teaching, given by the graduating class of 2004. Greenfield has been a Law Fund Research Scholar, a recognition of his scholarly contributions, since 2003. He has taught at the University of Connecticut School of Law and the University of Hawaii School of Law, and at Brown University in the political science department.
He is the founder and president of the Forum for Academic and Institutional Rights (FAIR), an association of three dozen law schools and other academic institutions organized to fight for academic freedom and against discrimination. FAIR brought suit against Donald Rumsfeld and others to contest the Solomon Amendment, which forces universities to assist military recruiters. The Supreme Court decided the case against FAIR on March 6, 2006. Greenfield’s work with FAIR was featured in numerous newspapers and media outlets, including the New York Times, the Wall Street Journal, the Boston Globe, the Chronicle of Higher Education, ABC News, CBS News, CNN, Fox News, MSNBC, CNBC, and NPR.
Greenfield also consults with litigators on issues of corporate accountability. He was instrumental in developing the theory of the case brought against Unocal Corporation for alleged human rights violations committed by the company in Burma.

Campbell, of the United States Court of Appeals for the First Circuit.

Legal Director, The Center for the Rights of Abused Children
Tim Keller is a lawyer who works to ensure all abused and abandoned children are safe and have access to their constitutionally guaranteed rights.
As senior vice president and legal director at the Center for the Rights of Abused Children, Tim’s public interest legal work seeks to defend the constitutional rights of children to be safe from abuse, to prompt timely placement with permanent parents, and to assure a child’s representation by legal counsel. In addition to constitutional litigation, Tim oversees the lawyers in the Center for the Rights of Abused Children’s one-of-a-kind pro bono Children’s Law Clinic and guides its policy initiatives.
When he and his wife, Lisa, hosted a teenage exchange student from Brazil several years ago, they realized how much they enjoyed helping a child thrive. The two felt called to help more kids. Over the following years, Tim and Lisa would become foster parents. Today, they enjoy offering respite care for children in foster care.
Intensely motivated by his time fostering children who’d been abused and neglected, Tim sees his work to ensure children have a constitutional right to counsel as a matter of life and death. As such, he’s particularly proud that in 2021 the Center for the Rights of Abused Children secured the rights of all children in Arizona’s foster system to be represented by legal counsel.
Before joining the Center for the Rights of Abused Children, Tim worked for nearly 20 years at the Institute for Justice. He served as lead counsel in Arizona Christian School Tuition Organization v. Winn, a U.S. Supreme Court victory that protected Arizona’s pioneering school scholarship program. Tim also led the team that secured a U.S. Supreme Court victory in Espinoza v. Montana Department of Revenue, which prevents states from discriminating against religious families and schools in educational choice programs. He has also litigated economic liberty and property rights cases in state and federal courts.
Tim earned his bachelor’s and law degrees from Arizona State University. He clerked for Robert D. Myers, at the time the presiding judge of the Maricopa County Superior Court, and for Ann A. Scott Timmer on the Arizona Court of Appeals.
Tim and Lisa live in Chandler, Ariz., with their four sons, Daniel, Benjamin, Ethan and Noah, and a miniature schnauzer named Gus who has more than 12,000 Instagram followers. The Kellers have traveled to 49 of the 50 United States, and are always looking for recommendations for new card or board games for family game nights.
