A highly accomplished trial attorney, Dion G. Rassias is a partner at The Beasley Firm, LLC.  Since he became a lawyer nearly four decades ago, Dion has been trying cases throughout the Commonwealth of Pennsylvania and the other five states where he is admitted to practice.  He has accumulated a record of unparalleled success across a wide spectrum of cases and legal disputes.  His diverse and broad legal background has led to verdicts and settlements in cases not only involving catastrophic personal injury emanating from medical malpractice and professional negligence, but also in complex commercial and business disputes, civil rights litigation, product defects, defamation, discrimination and all types of related insurance disputes.  Simply put, his legal practice is as uniquely diverse as all of the people and businesses he has successfully represented. 

Dion has won over $250,000,000.00 in settlements and verdicts on behalf of his clients. He is frequently called “a lawyer’s lawyer” for his ability and skills to efficiently represent fellow lawyers and other professionals facing legal disputes.  He has represented a growing list of celebrities, sports professionals, political figures and jurists, and his historical verdicts and cases have been featured by notable media outlets throughout the world, including The New York Times, The Independent The Washington Post, Sports Illustrated, The New York Post, People.com, The Daily Mail and The Philadelphia Inquirer.

In addition to trying cases, Dion has held many prominent leadership positions throughout the course of his practice.  Since 2018, he has been a member of the Disciplinary Board of the Supreme Court of Pennsylvania where he serves as the Board Chair.  He has served as Vice Chair for 2022, and before that, he was Chair of the Board’s Rules Committee for three years from 2019 through 2021.

He has served as the television moderator for the Pennsylvania Superior Court en banc oral arguments held at the National Constitution Center in Philadelphia.

Since 2021, he has been voted Best Lawyer in Delaware County by the Daily Times Readers’ Choice in the categories of Trial, Malpractice, Personal Injury and Product Liability.  Dion has been a “SuperLawyer” since its inception in 2004 and has multiple continuing recognitions as a Top 100 Lawyer in the Commonwealth of Pennsylvania and in Philadelphia.  He has received a Lifetime Achievement Award as one of America’s Top 100 Lawyers, has a “Superb 10.0” rating from Avvo.com and a “Judicial AV Preeminent” rating from Martindale-Hubbell.  He was also one of the youngest members ever appointed by the Justices of the Supreme Court to serve as a member of the Appellate Court Procedural Rules Committee, a group which drafts and revises the rules which govern appellate practice in Pennsylvania.

Mr. Rassias completed his undergraduate studies in three years from Stanford University and Dickinson College (B.A. 1984). He graduated from Duquesne University School of Law and was an academic selection to the Law Review (J.D. 1987). He is licensed to practice in Pennsylvania, New Jersey, Delaware, New York, Massachusetts, the District of Columbia, the United States Court of Federal Claims, the United States Supreme Court, and the federal courts in the states where he is admitted to practice.

It's your case, but it’s his reputation.  When smart people have done bad things to you, you’ll want someone with Dion’s experience, tenacity and background on your side.
