About
Sher Tremonte LLP is an elite litigation boutique founded in 2011, with offices in New York and Washington, DC. The firm represents companies and individuals in complex commercial disputes, regulatory enforcement actions, and high-stakes investigations, often involving parallel civil and criminal exposure. It is distinguished by a deep bench of trial-ready lawyers and market-leading strength in white collar defense and complex business litigation. The firm’s white collar practice is a cornerstone of its reputation. Its partners—many of whom have held senior roles in government—bring substantial experience handling matters involving securities and commodities fraud, insider trading, market manipulation, bank and healthcare fraud, accounting fraud, sanctions and anti-money laundering violations, bid rigging and other antitrust offenses, procurement and pandemic-related fraud, public corruption, and bribery. The team regularly represents clients in federal and state investigations, at trial, and on appeal, and is frequently retained in high-profile matters, including referrals from leading Am Law firms. Sher Tremonte’s complex business litigation department is its largest practice and spans a broad range of industries, including financial services, private equity, real estate, healthcare, hospitality, cannabis, and technology. The firm represents both plaintiffs and defendants in disputes involving fraud, securities violations, breach of fiduciary duty, restrictive covenants, and trade secrets, and is known for its ability to take matters through discovery, trial, and appeal with nimble, creative strategies tailored to client objectives. In the first three months of this year alone, the firm secured victories in three commercial matters, including a notable appellate win. A defining feature of Sher Tremonte is its training model, which emphasizes early substantive responsibility. Associates gain meaningful courtroom and case experience—examining witnesses, arguing motions and appeals, negotiating settlements, and addressing juries—far earlier than their peers at many larger firms. This approach enables the firm to deliver lean, highly skilled teams that execute efficiently without sacrificing sophistication. The firm also maintain a robust, high‑impact pro bono practice that mirrors the sophistication of its commercial and white collar work, including a landmark First Amendment win challenging Trump‑era efforts to suppress pro‑Palestinian advocacy, a current constitutional challenge to law enforcement DNA collection practices targeting protesters, impact litigation and advisory work connected to the Block ICE app and immigrant rights, and a series of high‑profile appellate and Supreme Court amicus engagements defending birthright citizenship, attorney‑client privilege, domestic violence survivors’ sentencing rights, and the independence of the legal profession.
