Our People/Steven D. Grimberg

Steven Grimberg is head of Nardello & Co.’s Atlanta office and General Counsel of the Americas, leading the firm’s efforts to develop and serve clients in the southeast as well as nationally. Before joining Nardello & Co., Steven served as an Assistant United States Attorney and a Deputy Chief of the United States Attorney’s Office for the Northern District of Georgia, where he investigated and prosecuted numerous complex white collar criminal cases involving corporate fraud, embezzlement, public corruption, insider trading, tax evasion, computer hacking, the theft of intellectual property and trade secrets, bank fraud, and health care fraud.

During his time with the US Attorney’s office, Steven helped supervise a section of approximately 25 federal white-collar prosecutors and other professionals. He developed and led a Cyber Crime Unit, comprised of prosecutors who worked closely with highly-skilled law enforcement agents from the FBI, United States Secret Service, Department of Homeland Security, and other law enforcement agencies to investigate, disrupt, dismantle, and prosecute some of the most prolific cyber-criminal organizations in the world. Steven served as a National Security Cyber Specialist for the US Department of Justice, which meant that he was the point of contact in the Atlanta metro area for all cyber-related threats and attacks that had national security implications. He regularly engaged in outreach to the private sector, collaborating on cyber defense practices through one-on- one meetings, seminars, panels, task forces, table top exercises, and case interactions.

One of his most high-profile cases involved the investigation and prosecution of a pair of individuals operating out of Vietnam and the Netherlands for hacking into at least eight email service providers around the globe and stealing confidential and proprietary information. At the time, this case was considered one of the largest known data breaches in history and was the subject of a congressional inquiry and testimony before the US House of Representatives. He also participated in a series of investigations and prosecutions relating to the development and distribution of the Citadel and SpyEye malware strains, which caused over $1 billion in losses to individuals and financial institutions around the world.

Steven has served for over 12 years in various capacities at the US Department of Justice, during which time he received numerous awards and recognitions, including the prestigious US Department of Justice Director’s Award on two occasions, most recently in 2017. Prior to becoming a prosecutor, he worked in private practice for seven years representing Fortune 500 companies and employers in complex civil litigation across the country.

Steven also serves as an Adjunct Professor at Emory Law School, where he teaches courses on criminal law, criminal procedure, and courtroom advocacy skills. He graduated from Emory Law School with distinction in 1998. Steven is a first-generation American whose family immigrated to the United States from Argentina.
