Patricia devotes her well-honed trial and investigative skills (as well as her intimate working knowledge of government process) to private clients, concentrating her practice in the areas of internal investigations, white collar criminal defense, corporate compliance, and litigation. 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.
Patricia also frequently advises individuals and businesses on their U.S. tax and foreign asset reporting (FBAR and FATCA) obligations, and represents individuals with undisclosed foreign bank accounts through the New York State and Internal Revenue Service (IRS) voluntary disclosure programs.
Chosen by the National Association of Criminal Defense Lawyers to instruct other attorneys in White Collar Criminal Defense, Patricia is AV Rated by MartindaleHubbell, and has been named a New York Super Lawyer and one of the “Legal Elite” of Litigation by Avenue Magazine.
