Mallory Silberman is an internationally recognized litigator with nearly a decade of first-chair experience in high-stakes disputes before international institutions. Clients and peers describe her as an “extremely skilled advocate” with “an extraordinary strategic mind,” and praise “her dedication [and] commitment” to client service” (see below).

At age 37, Ms. Silberman “is among the world’s most experienced young practitioners of investment arbitration”—a mechanism for resolving disputes between a sovereign country and a foreign investor. To date, Ms. Silberman has been counsel in more than 40 of these high-profile matters, representing not only well-known corporations, but also nearly eight percent of the countries in the world (including Chile, Costa Rica, the Czech Republic, the Dominican Republic, Guatemala, Hungary, the Kyrgyz Republic, Panama, Peru, the Philippines, the Slovak Republic, South Korea, Sweden, and Turkey). These cases have involved, among other things, intellectual property issues, transportation concessions, telecoms licenses, renewable energy, mining, bank regulation, environmental protection, taxation, and public health measures.

In 2019, Ms. Silberman was named one of the top five "under 40" international arbitration attorneys worldwide (Law360). Her work has also been recognized by Who's Who Legal (Global Leader in Arbitration, 2022) (Future Leader in Arbitration, 2017–2021); Latinvex (Latin America's Top 100 Female Attorneys, 2017–2021); The Legal 500 Latin America (Next Generation Partner in International Arbitration) (three times); Super Lawyers (Rising Star in International Law) (six times); and others.

In addition to being a partner at Arnold & Porter, Ms. Silberman currently serves as the chair of the International Dispute Resolution Committee of the DC Bar. She is also an adjunct professor at the Georgetown University Law Center, where she has taught since 2012. She frequently speaks at industry conferences; is a fellow of the Chartered Institute of Arbitrators; and is a member of the Peer Review Board of the American Review of International Arbitration.
