Joseph Petka is one of the most active trial attorneys in Philadelphia and its surrounding counties. He concentrates his practice on defending general liability claims involving catastrophic injuries and medical professional liability cases. He has tried a wide range of cases representing health systems, physicians, practice groups, nurses, and companies sued for security negligence, slip and falls, assaults, construction defective design, medical failure to diagnose, patient falls, pressure ulcers, and dental malpractice. He has obtained countless defense verdicts in jury trials throughout Philadelphia, Delaware, Chester, Bucks, and Montgomery counties. Fox 29 News recently profiled Joe’s successful verdict in a jury trial involving an assault and battery lawsuit. His attention to detail and thorough preparation is a hallmark of his successful representation of his clients.
Throughout his tenure at Goldberg, Miller & Rubin, Joe has also defended hundreds of motor vehicle cases. He was one of the first attorneys in the region to successfully defend a UIM/UM trial to verdict after the Supreme Court overturned the mandatory arbitration requirement in Koken. Since that time, he has obtained defense verdicts in more UIM/UM jury trials than almost any other Philadelphia civil defense attorney. VerdictSearch Magazine regularly features his trial victories.
Joe regularly serves as an arbitrator for the Philadelphia Court of Common Pleas and has been a guest speaker for the Pennsylvania Bar Institute. He has given presentations on premises liability defense, uninsured/underinsured motorist case strategy and trial practices, premises defense, and the anatomy of a civil lawsuit.
During law school, he worked for the Chester County District Attorney’s Office. Before that, he served as an infantryman in the Pennsylvania Army National Guard and was an amateur boxing champion.
Joe is an avid fan of boxing and politics, enjoys exercise, and resides in Delaware County with his wife and three children.
