Managing Attorney of the Arizona Office
Tim Keller serves as the Institute for Justice Arizona office’s managing attorney. 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 led the Institute’s defense of Arizona’s individual scholarship tax credit program in Arizona Christian School Tuition Organization v. Winn, which culminated in a United States Supreme Court victory. Tim also successfully defended Arizona’s Empowerment Scholarship Account Program, a publicly funded education savings account program he helped design to rescue special needs children, who were relying on Arizona’s state-funded tuition grant programs that were struck down in 2009 by the Arizona Supreme Court.
In addition to defending educational choice programs in Arizona and nationwide, Tim has helped knock down barriers to entrepreneurship on behalf of many hardworking individuals, including eyebrow threaders in Arizona, African hair braiders in Arizona and Utah, and florists in Louisiana. Among these victories was his work on behalf of Christian Alf, a teenager from Tempe, Arizona, who sought to help senior citizens rat-proof their homes 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 currently serves on the board of the Phoenix Lawyers’ Chapter of the Federalist Society, is a volunteer lawyer with the Arizona Center for Disability Law, and is the Scoutmaster of his oldest son’s Boy Scout Troop. 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.
