We represent corporate and individual clients in all stages of federal and state criminal proceedings, and in related regulatory investigations, including grand jury, securities commissions, criminal trials, and appeals, as well as before investigatory agencies.

Our experience runs the full gamut of business-related criminal matters: witness tampering, obstruction of justice, embezzlement, mail and wire fraud, money laundering, RICO, securities and tax crimes.
