Michael Cornacchia defends clients charged with criminal offenses, in federal, state and local courts.

He also represents clients in grand jury, law enforcement, administrative and regulatory investigations and proceedings.

Michael guides clients, as well, through corporate internal investigations and counsels them on employment entry and exit issues.

In representing his clients, in court, hearings, and investigations, Michael makes critical use of the experience and insights he gained as a federal, state and UN prosecutor. 

Since he has tried to verdict over 100 cases, Michael is prepared to seek vindication of his clients in the courtroom. However, it is always his goal to prevent his clients from being charged criminally, or civilly, or, if charged, get the accusations dismissed. To accomplish this, Michael ensures the best negotiated outcome possible for them, short of trial or hearings, by exhibiting a strong, well-prepared case.
