Marco focuses his practice on federal and state criminal defense, affirmative civil enforcement and regulatory matters, and election law. Prior to entering private practice, Marco started his legal career as an Assistant District Attorney in Allegheny County. As a prosecutor, Marco handled a wide variety of sensitive matters, including DUIs, narcotics cases, and felony prosecutions.

After serving as a prosecutor, Marco opened his own law practice where he represented clients in a wide range of criminal matters, including cases involving violent felonies, homicides, and allegations of multi-million-dollar fraud schemes.

As a defense attorney, Marco has successfully represented clients in numerous high-profile matters. He recently represented an executive with a major public institution accused of threatening multiple elected public officials—including a Court of Common Pleas Judge and an elected District Attorney. His motions practice resulted in a pretrial withdrawal of all felony charges and his advocacy ultimately resulted in a full acquittal on all remaining charges at the conclusion of a five-day jury trial.
