Nossaman LLP

In a town that regularly sees people come and go, Nossaman remains a familiar face. Our history in the nation’s capital extends back to the late 1970s. Our current office, established more than a decade ago, is the result of a merger with O'Connor & Hannan LLP. Today, the DC office’s litigators, transactional and regulatory attorneys serve clients in the transportation, environment, natural resources, and governmental sectors.
