Sean E. Quinn

About me

I am a trial lawyer dedicated to the representation of catastrophically injured individuals and their families in personal injury and wrongful death litigation throughout Pennsylvania and New Jersey. I specialize in complex civil litigation involving:


·         Construction Accidents

·         Industrial Accidents

·         Workplace Accidents

·         Tractor-Trailer Accidents

·         Brain Injuries

·         Electrocution

·         Burn Injuries

·         Medical Malpractice

·         Products Liability

·         Premises Liability

·         Motor Vehicle Accidents

·         Longshoremen Accidents


My expertise also extends to the representation of small businesses and construction companies in complex commercial litigation.


Known for my hard-hitting style and uncompromising work ethic, I have recovered over $50 million dollars in verdicts and settlements for my clients.  I have been recognized annually as a Super Lawyer by Super Lawyers-Pennsylvania and as a Rising Star by Super Lawyers-New Jersey. Only a handful of attorneys have achieved these honors from Super Lawyers in both New Jersey and Pennsylvania simultaneously.  I have also been recognized annually as a Top 40 Under 40 Trial Lawyer by the National Trial Lawyers Association.


Prior to founding the Quinn Law Group, I was an attorney at prominent Philadelphia-based plaintiff personal injury and defense firms. Prior to entering private practice, I was a Law Clerk for the Honorable Rosemarie Ruggiero Williams of The Superior Court of New Jersey. Clerking at the trial court level provided me with unique and invaluable insight into the judicial system.


I graduated from Franklin & Marshall College with Bachelor of Arts degrees in Government and History in 1997. At F&M, I was a Dean's List student and a member of the varsity football team - a team that won three conference championships. I went on to graduate from the Penn State-Dickinson School of Law with a J.D. in 2000. While in law school, I gained litigation experience as a legal intern for a civil trial judge in New Jersey, as a law clerk for a prominent Central Pennsylvania law firm, and as a legal intern in the Environmental Crimes Division of the Pennsylvania Attorney General’s Office. I also served as the captain of the Penn State-Dickinson Law National Trial Moot Court Team. In 2003, I continued my education by graduating with honors from the Temple University School of Law with an L.L.M. in Trial Advocacy.


I am admitted to practice in the state and federal courts of Pennsylvania and New Jersey, as well as the Third Circuit Court of Appeals.


I am a member of the American Association for Justice (AAJ), Pennsylvania Association for Justice (PaAJ), New Jersey Association for Justice (NJAJ), Philadelphia Bar Association, and Philadelphia Trial Lawyers Association (PTLA) where he is a member of the President's Select and Future Leaders Committee.
