During her tenure she made cyber threats a top priority and created the first nationwide network of national security cyber specialists.

Lisa spent six years as an Assistant United States Attorney in the United States Attorney’s Office for the District of Columbia prosecuting a range of cases, from violent crime to fraud and public corruption.

Her time as an AUSA includes service on the Enron Task Force, a group of federal prosecutors drawn from around the country to investigate and prosecute the fraud at Enron.
