Tim Keller serves as the Institute for Justice Arizona Chapter's executive director. He joined the Institute as a staff attorney in August 2001 and litigates school choice, economic liberty, and other constitutional cases in state and federal court.
Tim successfully defended Mesa brake shop owner Randy Bailey, when the City sought to take his property through eminent domain so it could hand it over to the owner of an Ace hardware store. He also helped author Arizona’s landmark property rights protection initiative, Proposition 207. He is currently defending Arizona’s individual scholarship tax credit program in federal court and is one of the co-authors of Lexie’s Law, a corporate tuition tax credit program designed to rescue the special needs children who were relying on Arizona’s state-funded tuition grant programs that were struck down by the Arizona Supreme Court.
In addition to his courtroom advocacy, Tim has earned a string of victories in the court of public opinion, challenging bureaucrats and forcing them to back down. Among these examples is his work on behalf of Christian Alf, a teenager from Tempe, Ariz., who sought to help senior citizens rat-proof their home by bending wire mesh around any openings. Until Tim stepped in on Alf's behalf, an Arizona state agency had demanded the young entrepreneur secure an exterminator's license.
Tim’s legal strategy is to not only fight for people’s civil liberties in the court of law, but also through legislation and the media.
Tim currently serves on the boards of the Arizona School Tuition Organization Association and the Phoenix Lawyers’ Chapter of the Federalist Society, and is a volunteer lawyer with the Arizona Center for Disability Law. He received his law degree from Arizona State University where he was the president of the Arizona State Federalist Society chapter and a member of the National Moot Court team. Before that, he earned his bachelor's degree in Economics from Arizona State University, graduating magna cum laude. Prior to starting law school, Tim worked as a research assistant at the Goldwater Institute, a state-based free market public policy organization.
Upon graduation from law school, Tim clerked for the then Presiding Judge of the Maricopa County Superior Court, Robert D. Myers. After leaving the Superior Court, Tim accepted a clerkship with the Honorable Ann A. Scott Timmer on the Arizona Court of Appeals. Tim and his wife Lisa have four sons, Daniel, Benjamin, Ethan, and Noah. He spends his free time taking care of his family, teaching Sunday school, and reading a book a week.
