Eric Olshan, a former United States Attorney and veteran federal prosecutor, helps clients navigate complex government investigations, enforcement actions, and high-stakes litigation. With nearly two decades of white collar experience, Eric brings a deep understanding of how complex cases are built—and how they can be resolved successfully. He is uniquely situated to advise clients in times of crisis and in a broad range of matters involving corporate and financial fraud, cyber and data security, national security, health care enforcement, and environmental regulation.

Prior to joining the firm, Eric served as the Presidentially appointed and Senate-confirmed U.S. Attorney for the Western District of Pennsylvania from 2023 until 2025, leading an office of 130 criminal prosecutors, civil litigators, and professional staff, and overseeing high-profile criminal prosecutions and civil enforcement matters with national and international significance. In this role, Eric chaired the Law Enforcement Agency Directors of Western Pennsylvania, a coalition of over 100 federal, state, and local law enforcement agencies.

As U.S. Attorney, Eric led the three-month capital trial of the shooter who murdered 11 worshipers at Pittsburgh’s Tree of Life synagogue in 2018, the worst antisemitic mass shooting in U.S. history. He also oversaw the multiagency criminal investigation of the 2024 assassination attempt on then-presidential candidate Donald J. Trump in Butler, Pennsylvania. Under his leadership, Eric’s office worked with domestic and international law enforcement partners on path-breaking cyber enforcement matters, including the disruption of a Russia-based cybercrime enterprise involving more than 40,000 spoofed websites and the illicit collection of personal information of more than a million victims.

During his tenure, Eric served on the Attorney General’s Advisory Committee (AGAC), a select group of U.S. Attorneys who advise Department of Justice (DOJ) senior leadership on national policy issues. He was also a member of AGAC subcommittees focused on white collar enforcement, terrorism and national security, civil rights, and environmental crime.

Before his confirmation as U.S. Attorney, Eric spent over 15 years as a white collar prosecutor, including 10 years based in Washington, D.C., as a Trial Attorney and Deputy Chief in the DOJ Criminal Division’s Public Integrity Section, and over five years as an Assistant U.S. Attorney and Chief of the Economic/Cyber/National Security Crimes Section in the Western District of Pennsylvania. Throughout his government career, Eric focused on investigating and prosecuting a broad array of criminal offenses, including mail and wire fraud schemes, money laundering, complex healthcare fraud, violations of the Foreign Corrupt Practices Act, criminal environmental violations, domestic public corruption, securities and accounting fraud, insider trading, obstruction of justice, and tax crimes.

Eric is a seasoned litigator, having practiced in federal courts across the country and tried more than two dozen cases to verdict, including federal white collar trials in seven federal districts. A skilled appellate advocate, he has handled successful appeals in the U.S. Courts of Appeals for the Third, Fourth, Fifth, and Eleventh Circuits.

Among his accolades, Eric received the Attorney General’s David Margolis Award for Exceptional Service, DOJ’s highest honor; and the Attorney General’s John Marshall Award for Trial of Litigation, DOJ’s highest recognition for trial practice. Eric began his government service through the Attorney General’s Honors Program after completing a clerkship on the U.S. Court of Appeals for the Ninth Circuit.
