Prosecutorial Ethics & Professional Standards

Every new prosecutor in Maricopa County Attorney’s Office is personally sworn in by me and later presented with a card containing these powerful words from Berger v. United States. This statement not only describes the unique role a prosecutor plays in our criminal justice system, it also reflects the expectations I have for our Deputy County Attorneys and the standard to which they are held. Our commitment to the residents of Maricopa County is to pursue justice ethically and with the highest integrity and professionalism.
