The Roseland, New Jersey, office of Marshall Dennehey opened in February of 1993. Since that time, it has realized substantial growth in response to client demand for our professional services. Roseland is in Essex County, home to Newark, New Jersey's largest city, and is within 30 minutes of New York City. The office services the densely populated counties of the northern part of the state. The attorneys practicing in our Roseland office have easy access to all of the federal and state courts of Northern New Jersey, which counties include Bergen, Essex, Hudson, Hunterdon, Middlesex, Monmouth, Morris, Passaic, Somerset, Sussex, Union and Warren.

Our Roseland office, like all of the firm's offices, provides the advantages of the personal attention of a small firm with the advantages that come from the intellectual property and broad-based experience of a large firm. The office is staffed by native and long-time residents of New Jersey who handle professional liability, product liability, employment, property and casualty, and workers' compensation defense litigation.
