Peter Mastroianni is a partner in Reichman Jorgensen’s New York office. He is a seasoned attorney with nearly 25 years’ experience focusing on ESI, E-Discovery, electronic evidence, information governance and knowledge management-related matters. 

As Discovery Counsel, Peter administers the collection, review, and production of documents, utilizing both human and artificial intelligence as necessary to provide the best results to clients. His clients have included a host of industry leaders, including Arconic, Alcoa, Merial, Rambus, and Corning, among others. Outside of litigation, Peter develops effective information governance and compliance plans for organizations seeking to minimize risk and maximize efficiency. 

Peter prioritizes understanding his clients’ business and operational needs and coordinates these items with legal and compliance requirements to develop customized ESI plans. The result: a comprehensive catalog of information that is identified, structured, expired and/or stored with maximum efficiency, minimum cost, and complete user satisfaction.

Peter earned his J.D. from Hofstra University School of Law where he was a member of Hofstra Law Review and graduated with distinction. He spent his first summer working for the Honorable Dorothy Eisenburg in the Eastern District of New York. He is also a graduate of Swarthmore College, where he earned a degree in philosophy.

Peter’s began his law career in 1994 with a boutique law firm in New York focused on representing banks and other lending institutions in real estate transactions. Soon after, he and a partner launched their own firm and grew the practice to several offices and a score of attorneys. Peter eventually ventured into the business side of real estate as a consultant for a startup financing venture. After just two years, 1st Capital Home Mortgage grew from three to more than 330 employees. Peter then returned to his law practice where he again focused on E-Discovery and information governance. 

As one of Reichman Jorgensen’s founding partners, Peter’s startup experience, technological acumen, and problem-solving skills provided a foundation to build the firm’s infrastructure. In his role as the firm’s Chief Innovation Officer, he continuously reviews, assesses, designs, creates, and applies new tools and technologies at the firm. Prior to joining Reichman Jorgensen, Peter worked at McKool Smith, where he managed the review and production of millions of documents in complex cases involving, at times, hundreds of attorneys under his supervision.
