Alex H. Loomis

Alex Loomis is a partner in the firm’s Boston office and a member of the firm’s appellate and sovereign litigation practices.  He has extensive experience in international and appellate litigation, especially in litigation involving foreign sovereigns and in foreign judgment and arbitral award enforcement actions and is often called upon to develop and implement enforcement strategies against hard-to-reach targets, especially foreign states.  Loomis has argued appeals before the First, Fifth, and Ninth Circuits and the Massachusetts Appeals Court, and has cross-examined an expert witness in a $100 million trial in Florida state court. 

Recently, Loomis was honored as a “Litigator of the Week” by The American Lawyer for his successful work in designing strategy to seize over $300 million in Argentinian bonds in a Southern District of New York proceeding and in successfully defending the attachment and turnover on appeal in the Second Circuit.  Previously, The American Lawyer interviewed Loomis for his successful appeal and vacatur of a multi-million-dollar judgment against the SEC on novel personal jurisdiction grounds, and he was a “Runner-Up” in The American Lawyer’s “Litigator of the Week” column for his work in obtaining a precedential First Circuit decision barring a tuition and fee refund class action arising from the COVID-19 pandemic against the University of Rhode Island.  Loomis has also been ranked in The Best Lawyers in America: Ones to Watch for Appellate Practice and Commercial Litigation every year from 2023-2025, and was named one of Boston Magazine’s Top Lawyers for Appellate Law in 2024.

Loomis regularly leads dispositive motion and appellate briefing in federal and state courts around the country on a broad range of subject matter, including administrative law, healthcare fraud, patent, antitrust, class actions, and general commercial litigation.  Loomis obtained a first-of-its-kind temporary restraining order forbidding the FDA from demeaning a pharmaceutical compounder’s products.  He also played a critical role in developing the dispositive motion strategy for disposing of class actions filed against five New England universities that sought tuition refunds following the transition to online instruction in Spring 2020 amidst the COVID-19 pandemic, obtaining two precedential First Circuit opinions and dismissal of suits against five of his clients.  And he obtained dismissal and affirmance on appeal of a state court false claims action filed against a major pharmaceutical company.  Loomis also maintains an active pro bono practice.

Before joining the firm in 2018, Loomis worked as a clerk to the Honorable Judge Debra Ann Livingston on the United States Court of Appeals for the Second Circuit.  Loomis graduated magna cum laude from Harvard Law School in 2017, where he won the Sears Prize and was a semifinalist and oralist in the Ames Moot Court competition.  He has published extensively on international and national security law.
