Marshall Dennehey
About
Practice/Organization Description WHO WE ARE A relentless defense. A respected reputation. A record of results. Marshall Dennehey is one of the nation’s largest civil defense litigation firms, with 500 attorneys across 19 offices in Pennsylvania, New Jersey, Delaware, Ohio, Florida, New York and Connecticut. Since 1962, we’ve partnered with insurers, self-insured businesses, municipalities, and professionals to deliver strategic, cost-conscious legal representation that protects what matters most. Our focus is simple: understand your risks, manage your litigation, and work relentlessly toward a successful resolution. Whether we’re defending a routine matter or a multimillion dollar, high-stakes claim, we stay aligned with your goals and committed to delivering results. HOW WE WORK Our attorneys are trial-tested and courtroom-ready, but equally skilled at helping clients avoid litigation altogether. As an Am Law 200 firm, Marshall Dennehey is home to some of the nation’s most respected litigators—each backed by dedicated associates, paralegals, and support teams working together to drive efficiency and performance. We know that litigation is more than a legal problem—it’s a business issue. That’s why our approach emphasizes early case assessment, budget predictability, and close collaboration. We tailor resolution strategies to your risk tolerance, and our internal systems—from e-billing and time tracking to electronic file audits—are built to control costs without compromising quality. We also develop custom litigation management programs when warranted, aligning legal strategy with your financial objectives. We’ve organized our work into four major departments—Casualty, Professional Liability, Health Care, and Workers’ Compensation—supported by nearly 50 specialized practice groups. From catastrophic claims and product liability to medical malpractice and employment law, we offer deep experience in virtually every facet of civil litigation. A LONG-TERM COMMITMENT TO OUR PEOPLE -- AND YOURS We believe that an informed client is an empowered one. Our clients receive timely legal updates, breaking case law alerts, and in-house seminars that help claims staff stay ahead of legal and regulatory changes. At Marshall Dennehey, we invest in our people for the long term. Many of our attorneys spend their entire careers here, and we prioritize ongoing training, mentoring, and development. That translates into consistency, institutional knowledge, and lasting relationships.
