Susan Dennehy
Raised in a small town in Indiana, Susan Dennehy’s interest in medicine began when she worked during high school at her father’s medical office and accompanied him on house calls. He is a general practitioner. Susan attended Purdue University and then earned her J.D. degree from the Washington College of Law of the American University in Washington, D.C., where she was a member of the Law Review.

Her first job as a lawyer was at a prominent law firm in New York City that handled the defense of major and complex medical malpractice lawsuits. The firm represented doctors and hospitals. As a trial lawyer and partner, Susan gained legal experience and knowledge of the accepted standards of medicine, including the rules that govern doctors and hospitals.


In 1996, she began her own firm, the Dennehy Law Firm. The firm is devoted exclusively to representing patients and their families in medical safety cases. Her diverse legal experience for both sides gives her a unique perspective on the practice of medicine and the rules that regulate doctors and hospitals.


Along with her legal career, Susan worked as a television reporter in a top broadcasting market. As a journalist, she learned to quickly synthesize information and tell a story. These skills serve her well in her legal practice. She also publishes articles and lectures on medical legal issues of importance, including hospital acquired infections, preventable medication errors, women and heart disease, and plastic surgery. Susan has also been an invited commentator on Court TV to discuss legal issues in medical malpractice trials.


Today, Susan is an active member of the American Association for Justice and The Belli Society, an international group of distinguished trial attorneys. She is also a member of the New York Women’s Bar Association and the Lawyer’s Division of Judges and Lawyers Breast Cancer Alert (JALBCA). She has served on committees of the New York City Bar Association, including the Lawyer’s Assistance Program, an organization that helps substance-impaired attorneys.


Susan has lectured nationally on courtroom strategies and has taught trial skills to law students at Cardozo School of Law’s annual trial program. She is a member of the award winning TRIAL magazine publication committee and is a reviewer and author.
Susan Dennehy has achieved the “AV® Peer Review Rating,” the highest distinction awarded by Martindale-Hubbell®.
