Dion G. Rassias

As recognized by American Lawyer Media, “Dion meets that supreme standard of being a ‘lawyer’s lawyer’. That is to say, if I were in trouble, I would want him representing me.” In a world where everyone claims to be a “trial lawyer”, Dion really is. He has stood victorious in the courtroom in all types of cases, from cases involving catastrophically injured members of our community, to business disputes, complex litigation(s) and insurance matters. As you will see, trying cases is what he does.

Dion has tried and settled a growing list of cases covering a diverse and broad spectrum of legal issues, which have resulted in over $250,000,000 million in verdicts and settlements for people and families who have been catastrophically injured and damaged as the result of medical malpractice, professional malpractice, partnership disputes and law firm disassociations, defamation and false light, products liability, civil rights violations, discrimination and harassment, and related personal injury actions. In addition, he has tried and settled many complex commercial litigations involving business disputes, antitrust claims, contracting disputes, healthcare issues, bank fraud and trade secret litigation. He even sued the Board of Ethics in Philadelphia and won a published retraction on its claims alleging campaign finance violations. Simply put, his legal practice is as uniquely diverse as all of the people and businesses he has successfully represented.

Dion’s cases have been covered by some of the most significant media outlets all over the world, and his clients include Taylor Swift, former heavyweight boxing champion Larry Holmes, Baseball Hall of Fame’s Harry Kalas, as well as numerous elected officials throughout the Tri-State area, including Mr. Justice Seamus P.
