Practice groupLitigation, Arbitration, and Employment

Zachary Best is a thoughtful litigator whose practice focuses on class actions. He has represented well-known clients in antitrust, ERISA, RICO, and TCPA cases.

His experience covers every phase of class action litigation, including motions to dismiss, data and document discovery, motions to exclude expert testimony, class certification, appeals, and settlement negotiation. He recently shepherded a dozen clients through a months-long data production in connection with one of the largest antitrust multidistrict litigations in history. Before that, Zachary was part of a team that won denial of class certification in a RICO case seeking US$1 billion in damages.

Zachary is also committed to representing underserved communities through pro bono work. Most recently, Zachary has been a principal member of the team litigating M.M.M. v. Sessions, a class action filed on behalf of immigrant children who were separated from their parents at the border and denied the opportunity to seek asylum. Prior to his work on M.M.M., Zachary assisted three Washington, D.C. residents to avoid eviction and keep their subsidized housing.

Prior to joining Hogan Lovells, Zachary clerked for the Honorable Michael P. Shea of the U.S. District Court for the District of Connecticut. During law school, he served as staff editor of The Georgetown Law Journal and worked at a number of nonprofit organizations in Washington, D.C.
