About Mark
Mark Harris is an experienced Pennsylvania attorney whose legal life stretches back to the early 1980s. He earned his juris doctor from Temple University in 1980. That academic foundation set the direction for a steady practice rooted in the courts of Pennsylvania and federal court in the Eastern District of Pennsylvania.
After law school Harris entered private practice and built a career centered on courtroom work and case preparation. Over the decades he has handled matters that required courtroom presence and federal filings. He is admitted to practice in Pennsylvania and in the U.S. District Court for the Eastern District of Pennsylvania. Those admissions shape the geographic and procedural contours of his work.
In 2022 Harris took on the role of of counsel at Warren McGraw & Knowles LLC. The title reflects a senior advisory role at the firm. In that capacity he provides guidance on litigation strategy, drafts pleadings and supports trial preparation. His practice approach emphasizes careful file review and steady courtroom representation. Colleagues describe him as methodical in litigation planning and reliable under pressure.
Harris maintains active memberships in the Pennsylvania State Bar and the Montgomery Bar Association. He participates in association activities and stays current on developments in state and federal procedure. Those memberships also offer him a forum to exchange practice tips with peers and to refresh litigation skills through continuing legal education.
Long experience in state and federal venues has given Harris a practical perspective on case management and trial dynamics. He has represented clients in matters that require coordination between state courts and the federal system. He favors clear, direct communications with clients and a disciplined approach to evidence and deadlines. That steadiness is a throughline in his work.
Now serving of counsel at Warren McGraw & Knowles LLC, Harris continues to take cases that involve Pennsylvania trial courts and filings in the U.S. District Court for the Eastern District of Pennsylvania. He focuses his current practice on representing clients in matters in those courts and providing senior-level litigation support to the firm.
