Ben, a former White House and U.S. Treasury Department official, advises U.S. and non-U.S. clients on the regulatory aspects of cross‑border mergers, acquisitions, dispositions, investments and other transactions. He is known in particular for deep experience on matters relating to the Committee on Foreign Investment in the United States (CFIUS).

In five years of government service, Ben held senior legal and policy roles involving national security and foreign investment. He is one of few practitioners to have served as both a CFIUS lawyer at Treasury and a CFIUS policymaker at the White House, giving him deep, hands‑on experience with every facet of the CFIUS process, from conducting initial jurisdictional analyses to coordinating presidential prohibitions.

Ben is recognized for his CFIUS work by Chambers USA, where a source says he “expertly guides you through the lifecycle of the CFIUS process, acting as an approachable and trusted partner to both the in-house team and the business.”
