About Stephanie

Stephanie Giammarco leads a team of multidisciplinary professionals providing litigation and forensics services to middle market corporations and their counsel. We help our clients respond to time-sensitive, global matters by combining industry knowledge and experience with cutting-edge technology to yield comprehensive, cost-effective solutions that hold up under legal and regulatory scrutiny.


Stephanie focuses on forensic technology and data analytics, including the application of robotic process automation, machine learning and artificial intelligence. For over 25 years, she has worked with organizations and their counsel on domestic and international investigations and litigation, garnering significant media attention. Areas of focus include financial statement and securities fraud, class action lawsuits, labor and employment litigation, theft of trade secrets, internal investigations, and breach of contract. Her teams have been responsible for the collection, preservation, and analysis of documents and data belonging to thousands of custodians, yielding billions of data points. Most recently, Stephanie was appointed leader of the Data Clearinghouse for the NPM Adjustment to the Tobacco Master Settlement Agreement, reporting to 36 state attorneys general and multiple tobacco manufacturers in the annual analysis of over 100 data sets to assess compliance with the settlement agreement.

Stephanie’s work has been reviewed and relied upon by governmental agencies; she’s been deposed as an e-discovery witness under Rule 30(b)(6) of the Federal Rules of Civil Procedure; and she’s testified in arbitration on the calculation of damages in contract disputes based on millions of data points. She has published and presented on a range of data analytics, digital forensics, and e-discovery topics, including before the Securities and Exchange Commission, the Security Industry Association, and the National Futures Association.
