Adam R. Mandelsberg
Adam is committed to resolving bet-the-company disputes efficiently and to his clients' satisfaction.
Adam Mandelsberg prosecutes and defends high-stakes litigation on behalf of public companies, financial institutions, sports leagues and player agents, and individuals in federal and state courts nationwide. He has successfully defended a range of product manufacturers accused of fraud and other business torts, including those in the food and beverage, dietary supplement, and pet product industries. Adam also represents leading service providers, including pioneering technology platforms, colleges and universities, and testing companies.
Adam represents businesses in sensitive commercial disputes, including breaches of supply and license agreements, issues related to corporate mergers and acquisitions, and business torts. He also advises directors and shareholders on cutting-edge issues of corporate law, including alleged breaches of fiduciary duty and petitions for director removal and corporate dissolution.
Adam's notable successes include defending a global financial institution accused of fraud relating to a rogue trader's scheme to disguise hundreds of millions of dollars in losses. He also successfully represented a London-based interdealer broker in a lawsuit alleging racketeering and unfair competition against a competitor and secured the dismissal of investors' claims in a decade-long securities-related class-action lawsuit on behalf of a leading pharmaceutical company.
Adam maintains an active pro bono practice. His clients have included a New Yorker who claimed unlawful and excessive force by law enforcement agents in the course of his arrest at his own home; a Texas death row prisoner seeking to overturn his conviction and sentence in federal court; public housing residents seeking apartment repairs; and Central American migrants seeking recompense for their unlawful separation from minor children by U.S. agents.
A former clerk for the Hon. Jane R. Roth of the U.S. Court of Appeals for the Third Circuit, Adam also served as an extern to the Hon. Robert D. Sack of the U.S. Court of Appeals for the Second Circuit and as an intern to the Hon. J. Paul Oetken of the U.S. District Court for the Southern District of New York.
