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 extensive trial and appellate experience in state and federal courts and regulatory agencies throughout the six states where he is admitted to practice. He has tried and settled a growing list of cases which have resulted in multi-million dollar verdicts and settlements, all of which have been collected in full, for people and families who have been catastrophically injured and damaged as the result of medical malpractice, professional malpractice, 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. His clients include Taylor Swift, former heavyweight 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. McCaffery, whose lawsuit against The Philadelphia Inquirer has been described as one of the most significant First Amendment cases in the history of Pennsylvania.

In addition to his work on commercial litigations and for catastrophically injured plaintiffs, Dion also represents one of Pennsylvania’s fastest growing domestic insurance companies. He serves as that company’s lead trial counsel on major litigation matters throughout the Commonwealth and defends bad faith claims, civil rights cases, discrimination and harassment, fire and explosion cases, subrogation, general liability claims and coverage disputes.

Dion has a “Superb 10.0” rating from, and has maintained a “preeminent AV” rating from Martindale-Hubbell for three decades. He is a member of The National Trial Lawyers Top 100, and also the Million Dollar Advocates Forum and the Multimillion Dollar Advocates Forum.

Dion has been selected as a Pennsylvania ‘Super Lawyer’ by Philadelphia Magazine and Law & Politics, and has continuing recognitions for being in the Top 100 lawyers in the Commonwealth of Pennsylvania and also the Top 100 of lawyers in Philadelphia since the inception of “Super Lawyers” in 2004. This recognition is based upon a survey of over 34,000 lawyers and judges from the Commonwealth to determine the top 5% of attorneys practicing in Pennsylvania, and can be viewed in the “Ultimate Guide to the Top Lawyers in Pennsylvania”, found at

In June of 2010 he was appointed by the Pennsylvania Senate to participate in the Joint State Government’s Commission (Senate Resolution 344 of 2010), to study and investigate the criminal justice system in Philadelphia and to develop solutions for the problems involving high violent crime rates, low conviction rates, the bail system, witness intimidation and other matters of significant and important public interest. This advisory committee is comprised of approximately thirty judges, lawyers and prosecutors.

In October of 2011 and 2007, he served as the moderator for the television coverages of The Pennsylvania Superior Court’s en banc oral arguments at the National Constitution Center. Dion provided case introductions, commentary and analysis of the Court arguments.

In January of 2004, he was appointed by the Pennsylvania Senate as a member of the Joint State Government Commission Task Force on Real Property Law (Senate Resolution 244 of 2002). This Joint Commission is a standing group of attorneys and judges from across the Commonwealth who provide legal experience and advice to assist the General Assembly by recommending improvements and changes to Pennsylvania laws.

In October of 2003, Dion was selected by America Lawyer Media, The Legal Intelligencer and the Pennsylvania Law Weekly, as one of Pennsylvania’s forty best lawyers under the age of 40. This award represents the Pennsylvania legal world’s recognition of lawyers across the state who have worked tirelessly in their professional, personal and civic lives to improve the legal landscape and the future of others.

In May of 2002, he was requested to testify before the Pennsylvania Senate Judiciary Committee on Senate Bill 1376, on Joint and Several Liability. His diverse experience representing corporations, plaintiffs and insurance defendants helped clarify and articulate issues and concerns about the proposed legislation.

In January 2001, he became one of the youngest members ever appointed by the Justices of the Supreme Court of Pennsylvania to serve as a member of the Appellate Court Procedural Rules Committee, the group which drafts and revises the rules which govern appellate practice in Pennsylvania.
