About Mark

Mark Stuaan focuses his practice on white collar criminal investigations and litigation defense in state and federal courts. Having served as a prosecutor himself, Mark understands the prosecution’s perspective, what drives the prosecution, and how they view a case. Mark draws on this experience when advocating his client’s position. Before joining Barnes & Thornburg, Mark served as an assistant United States attorney for the Southern District of Indiana for almost a decade. He was assigned to the criminal division in the United States attorney’s office in Indianapolis and handled a number of prosecutions and appeals. Prior to joining the U.S. attorney’s office in Indianapolis, Mark served as an assistant United States attorney for the Central District of Illinois, where he handled civil, criminal and appellate matters for approximately five years. Currently, Mark was part of the attorney team assisting Barnes & Thornburg partner Larry Mackey, the independent corporate compliance monitor for a large U.S. medical device manufacturer and distributor, pursuant to the company’s deferred prosecution agreements with the U.S. government.
