Am Law 200 civil defence litigation firm founded in 1962, with about 500 attorneys across 19 offices handling casualty, professional liability, health care and workers' compensation matters for insurers and businesses.
Marshall Dennehey is one of the largest civil defense litigation firms in the United States. Founded in 1962 in Philadelphia by Francis E. Marshall, Gerald Dennehey, John R. Warner, Robert J. Coleman and Robert St. Leger Goggin, it has grown from a small local practice into an Am Law 200 firm of approximately 500 attorneys. Its client base comprises insurers, self-insured businesses, professionals and municipalities, and its work spans matters from routine low-exposure claims to high-profile cases involving multi-million dollar demands, multiple plaintiffs and numerous codefendants.
The firm's practice is organised into four departments: Casualty, Professional Liability, Health Care and Workers' Compensation. Each handles defence litigation in its respective field, giving associates exposure to a range of civil defence work rather than a single niche.
Marshall Dennehey operates 19 offices across seven states and neighbouring jurisdictions, including locations in Philadelphia, Pennsylvania, Connecticut, Delaware, Florida, New Jersey, New York and Ohio. The firm describes its approach as cost-effective, intelligent and pragmatic, working collaboratively with clients to assess exposure and shape resolution strategies. Attorneys are expected to be trial-ready and prepared to advocate in court where settlement cannot be reached.
