Marisa also served as a prosecutor in the US Attorney’s Offices for the Eastern District of Virginia and the District of Maryland, where she investigated and prosecuted cases involving narcotics trafficking, health care and immigration fraud, money laundering, export control violations, and child sex trafficking. She won every trial and appeal as a prosecutor.
