Justin M. Sher

Justin counsels and represents clients in complex commercial disputes as well as regulatory and criminal investigations. A thoughtful and tenacious advocate, he has served as lead counsel in multiple trials and regularly represents clients in federal and state courts, in arbitration proceedings, and before government agencies and regulatory bodies.

Justin has achieved victories on behalf of both plaintiffs and defendants in a wide range of high-stakes matters, including cases involving contract disputes, business breakups, professional liability allegations, breach of fiduciary duty claims, trust and estate issues, and allegations of securities fraud. He has also successfully defended clients against allegations of insider trading, market manipulation, government corruption, accounting fraud, antitrust violations, and tax fraud.

Justin thrives on complex issues, taking a strategic approach to finding solutions where others have failed. Clients laud his creativity, credibility among judges and opposing counsel, and unflagging commitment to achieving superior outcomes on their behalf.

Before founding Sher Tremonte in 2011, Justin worked at Davis Polk & Wardwell LLP and Kobre & Kim LLP, served as a Special Assistant District Attorney for the Kings County District Attorney’s Office, and, prior to law school, worked for the Financial Frauds Bureau of the New York County District Attorney’s Office.
