Kirstin Ault is a 15-year veteran of the United States Attorney’s Office for the Northern District of California, where she served in the Appellate, Criminal, and Civil Divisions.  Kirstin has over 20-years of appellate experience, litigating over 50 appellate cases before the Ninth Circuit Court of Appeals.


Kirstin’s work with the USAO’s Appellate Division focused on constitutional challenges to criminal convictions and statutory interpretation.  As the Supreme Court’s jurisprudence on the vagueness doctrine evolved to impact a variety of criminal and immigration statutes, Kirstin coordinated with other offices in the Ninth Circuit and the U.S. Department of Justice to develop a coherent strategy for adapting to a rapidly changing area of constitutional law.  In addition, Kirstin’s work has covered challenges to sentencing, restitution orders, and conditions of supervised release and probation, along with interlocutory appeals challenging bail conditions and rulings on trial motions.


Kirstin also served in the USAO’s Economic Crimes and Securities Fraud section where as Health Care Fraud Coordinator she oversaw the Northern District’s health care fraud litigation and handled a variety of white-collar cases, focusing on regulatory matters with a False Claims Act component.  Kirstin has tried over 20 federal jury trials and is available to consult on trial strategy and motions practice, with an eye toward potential appellate issues.


Kirstin was recognized as one of the Top 100 Lawyers in California by the California Daily Journal in 2014 and received the Executive Office of United States Attorneys Director’s Award in 2016.


Kirstin graduated from Stanford Law School in 1999, and clerked for the Honorable Joel Flaum on the Seventh Circuit Court of Appeals.  Since 2016, Kirstin has regularly served as an instructor for Stanford’s Trial Advocacy seminar and moot court competitions.
