Criminal Defense
Our White Collar Group is dedicated to the specific needs of our clients, which range from large corporations to individual actors. With a deep bench of former government attorneys and prosecutors, we have a proven track record of success in keeping many of our clients from being charged and avoiding publicity about investigations. When unable to resolve such matters through alternative dispositions, we have vigorously defended our clients at trial. Our attorneys have represented companies and individuals in a vast array of criminal matters in state and federal court, including grand jury inquiries, public corruption, healthcare fraud, government and Department of Defense contracting fraud, false claims, environmental, tax, banking, bribery, campaign finance, ERISA, labor relations, RICO, trade secrets, perjury, false statements, obstruction of justice, money laundering, mail and wire fraud, and conspiracy.
Internal Investigations
We are often retained to conduct highly sensitive, internal investigations for the purpose of identifying breaches of policy regarding the protection of proprietary data, betrayal of the corporate trust, breach of fiduciary obligations, and violations of state or federal laws and regulations. Our investigations team has worked in highly regulated industries, including healthcare and insurance.
