Kevin P. O’Brien

Partner – Trial Attorney

 Kevin is a partner and trial attorney at Stampone O’Brien Dilsheimer Holloway where he focuses his practice on complex catastrophic personal injury claims and wrongful death claims. Kevin’s representation involves individuals, families, and businesses who are victims of the wrongful acts of others which have resulted in serious personal injury and wrongful death as a result of medical malpractice, products liability, construction accidents, premises liability, automobile and trucking accidents.

He has represented victims of physical and sexual abuse by medical professionals, and in institutional settings such as schools, summer camps, and in the foster care system.  He has also represented clients in claims for personal injuries caused by defective drugs and medical device products.

Currently Kevin is significantly involved in the National Prescription Opiate Litigation, representing individuals and governmental entities against the drug companies which contributed to the Opioid Crisis across the United States.  Kevin is also one of the leading attorneys in the Country on behalf of infants who have died from asphyxia and suffocation in the “Infant Inclined Sleeping Products” which have been recalled by the Consumer Product Safety Commission. 

In addition to the monetary sums he has recovered, his legal work has led to the exposure of wrongdoing by large corporations and insurance companies. His work has resulted in changes that have made people safer at work, on the roadways, and in their homes.  In a recent product liability case, as a result of Kevin’s work, the manufacturer of a piece of construction equipment which killed a young worker changed their sales practices to ensure that a piece of optional safety equipment was required to be sold with all products in the future. 

In another recent case, Kevin’s legal work resulted in an historic settlement with the City of Philadelphia in which they agreed to provide tasers to their entire police force at a cost of approximately $14 Million.  The officers who shot Kevin’s client were not equipped with tasers when they encountered his client, a man in a mental health crisis.  The city also agreed to pay a multi-million-dollar settlement to the victim’s family.    

Many of his colleagues often turn to him by referring difficult and high-stakes cases for litigation and trial.  Kevin has tried numerous significant cases to juries and judges around the country including serious personal injury cases, wrongful death cases, negligent security cases, maritime wrongful death cases, premises liability cases, and more.  Other successful cases which Kevin has worked on include:
