About Sam


[email protected]

Samuel O. Maduegbuna, the founding partner of Maduegbuna Cooper LLP, is an experienced litigator and trial lawyer with a particular expertise in complex and challenging cases including employment discrimination, civil rights and commercial matters. He has successfully represented clients in high-stakes trials against municipalities, multinational corporations and financial institutions, and he obtained significant jury verdicts as well as negotiated multiple six- and seven-figure settlements on behalf of clients.

Sam’s practice focuses on trial and appellate practice, arbitration and mediation, principally in the areas of labor and employment, personal injury, medical malpractice, civil rights and commercial matters. Sam has tried cases in federal and state courts and arbitrated these matters before a wide range of arbitral tribunals. He has argued critical motions and appeals, including conducting the oral argument before the United States Court of Appeals for the Second Circuit in a seminal decision on whether state common law torts arising from workplace drug testing are preempted by Federal Drug Testing Regulations applicable to workers in safety sensitive positions in the transportation industry. He has also argued and briefed appeals in the United States Courts of Appeals for the Eleventh and District of Columbia Circuits and the Appellate Divisions of the New York State Supreme Court.

Sam has extensive experience in corporate and commercial law particularly as it relates to banking and international commercial transactions. In that regard, he has represented a number of U.S.-based foreign banks in diverse aspects of their banking business by providing issue-specific legal support for various forms of credit facilities, such as term loans, letters of credit, syndicated loans, risk-participation and other asset-based and non-asset-based lending transactions. A substantial portion of Sam’s practice is also devoted to commercial litigation arising out of interests in securities and banking-related litigation.

Sam is also a frequent public speaker and panelist at seminars and conferences in the areas of civil rights, international commercial arbitration and alternative dispute resolution.

Sam is actively involved in handling litigation matters on a pro bono basis. His efforts on one such matter led a U.S. District Judge to note that he “has gone above and beyond the obligations of his initial appointment on his client’s behalf.”
