Attorney Information

Overview

John has an unmatched legal profile. A graduate (with distinction) from the University of Arizona in 1985, John went on to attend the University of Arizona law school where he received his Juris Doctorate in 1988. During law school, John was a member of the Arizona Law Review. During law school, John had the honor of spending a semester in Washington, D.C., working on "the Hill" for then Senator Dennis DeConcini. After law school, John landed a prestigious federal judicial court clerkship for Judge Alfredo C. Marquez.

In 1990, John was then selected as an Assistant United States Attorney for the U.S. Attorney's Office, where he spent nine years representing the United States of America in the Criminal Division. John received a Special Achievement Award for Sustained Superior Performance of Duty from the U.S. Department of Justice in 1992. As a federal prosecutor, John litigated approximately fifty federal jury trials in the U.S. District Court and presented over 15 oral arguments before the Ninth Circuit Court of Appeals in San Francisco. John has also authored approximately forty Ninth Circuit Court Appellate briefs.

In 1999, John entered private civil practice with the firm of Haralson, Miller, Pitt, and McAnally, where he was an associate to Dale Haralson for three years. During this time, John authored two "Amicus Curiae" Briefs, one that was filed with the U.S. Supreme Court [Norfolk Southern R. Co. v. Shanklin, 529 U.S. 344 (2000)] and another filed with the Arizona Supreme Court [Isbell v. State, 198 Ariz. 291 (2000)].

John opened his legal practice in 2007 and continued private civil litigation on behalf of his clients at the Leader Law Firm. John is a member of the American Trial Lawyer's Association, the Arizona Trial Lawyer's Association, and the Western Trial Lawyer's Association.

In February 2012, John obtained a $7.8 million dollar wrongful death jury verdict against the State of Arizona.
