She has represented individuals and businesses confronted with allegations of criminal conduct regarding government contracts, antitrust, corruption, tax, securities, fraud, insurance, identity theft, bankruptcy, and environmental issues.  She has successfully served her clients in grand jury investigations, trials, sentencings, and appeals in federal and state courts.

Businesses regularly call upon Patricia to conduct internal investigations of improper accounting practices, diversion of corporate funds, government contract fraud, conflicts of interest, public corruption and kickbacks. Thanks to her efforts, these internal actions often lead to internal solutions.
