Silvio A. Trentalange represents both plaintiffs and defendants in complex and commercial civil litigations. Silvio provides clients strategic guidance and has worked cases from pre-litigation investigation through trial and appeal. He has argued discovery and dispositive motions before federal and state courts, and led briefing projects on intricate legal issues before the United States Third Circuit Court of Appeals and United States Supreme Court.

More specifically, in commercial disputes, Silvio handles matters concerning breach of contract, breach of fiduciary duties, tortious interference with business relations, unfair competition, and related theories of recovery before arbitrators or federal and state courts.

Silvio also assists requesters and direct interest participant third parties in Pennsylvania Right-to-Know Law matters before the Pennsylvania Office of Open Records, Courts of Common Pleas, and Commonwealth Court. Silvio’s Right-to-Know Law cases have canvassed nuanced areas of the law focusing on a business’s trade secreted or confidential proprietary information.  

Prior to joining Dilworth, Silvio worked at a prominent Philadelphia plaintiff’s firm handling complex cases concerning toxic tort and products liability class actions, commercial-consumer arbitrations, wrongful death, and catastrophic injury.

Silvio is a graduate of Temple University’s Beasley School of Law, where he graduated cum laude. While in law school, Silvio served as an intern for the Honorable Timothy J. Savage in the U.S. District Court for the Eastern District of Pennsylvania. Additionally, he worked as a clinical intern for the Philadelphia City Solicitor’s Office – Civil Rights Unit, the Pennsylvania Innocence Project, and the Philadelphia District Attorney’s Office.

Search Tips

Our Web site's search function employs a variety of techniques to help you make the most of your queries. In this tips section we use square brackets [ ] to signal queries, so [antitrust and litigation] is one query, while [antitrust] and [litigation] are two.

  • Exact phrases: Eliminate unnecessary search results by surrounding your search phrase with quotation marks. Placing ["project finance"] in quotes will return specific results and discard additional results that simply have the words "project" and "finance" peppered on a page.
  • Wildcard symbol: If you're not exactly sure how a piece of information you want is phrased, use the following symbol (*) as a word root expander. A search for [child*] will find not only "child," but also results with words like "children" and "childhood."
