He is a Fellow of the American College of Trial Lawyers.

Jon is a former federal prosecutor and United States Supreme Court law clerk. In 2023, the State of Colorado appointed him as a Special Prosecutor to try the first case against police officers arising from the death of a young man named Elijah McClain while in police custody. The trial generated national attention and resulted in the conviction of the lead officer on homicide and assault charges. Also while in private practice, the State of Illinois appointed Jon a Special Assistant Attorney General to help the Illinois Attorney General's office organize and operate a Public Integrity Unit.

As a former federal prosecutor, Jon often defends clients in regulatory and criminal investigations and has conducted many internal investigations at Fortune 100 and smaller corporations. Jon worked at the United States Attorneys’ Office in Chicago for almost nine years before entering private practice. He was Deputy Chief for the General Crimes Division and the lead prosecutor in a series of high-profile cases: the prosecution of the Ford Heights, Illinois Chief of Police and six other police officers on corruption and racketeering charges; various cases arising out of the Silver Shovel investigation into political corruption in City and State government; a terrorism case involving the efforts of a Puerto Rican independence group to bomb a military recruiting center; the prosecution of a large Chicago street-gang that attempted to purchase military weapons for the purpose of attacking a Chicago police station; and a series of fraud prosecutions involving securities and other types of businesses. At the Department of Justice, he received the Department of Justice’s Director’s Award for Superior Performance as an Assistant United States Attorney and four Department of Justice Special Achievement Awards.

A former law clerk to Justice Byron White and Judge James L. Buckley, Jon has argued over 20 appellate cases in various federal and state appellate courts, including for example four appellate arguments on civil matters before the California appellate courts. He has been successful in the vast majority of these appeals.

He has previously taught these courses: European Union Law; Evidence (the basic evidence course); Corporate Crimes & Investigations; Federal Criminal Law; Franchise & Distribution Law; and a course on the Sarbanes Oxley Act.
