About Jonathan
Jonathan Warren built his legal foundation in the late 1970s and early 1980s. He earned a Bachelor of Arts from Binghamton University in 1978 and completed his J.D. at Temple University Beasley School of Law in 1981. Those years shaped his approach to practice and introduced him to the demands of courtroom work.
After law school he became licensed to practice in Pennsylvania. He has spent decades in the legal community of the state. His career has included long-term involvement with trial and justice organizations, which has kept him connected to changes in litigation practice and professional standards.
Warren has been associated with Warren McGraw & Knowles LLC. He practices at that firm in Pennsylvania and has done so over an extended period. His firm tenure sits alongside steady membership in several bar and trial lawyer groups, giving him a broad professional network and exposure to peer developments and continuing education offerings.
Memberships tell part of the story. He has been a member of the Pennsylvania Association of Justice since 1981 and joined the American Association for Justice in 1982. He became part of the Montgomery County Bar Association in 1984 and remains active there. Since 2003 he has also held membership in the Philadelphia Trial Lawyers Association. Those affiliations reflect sustained participation in organizations focused on litigation, trial procedure and advocacy.
Colleagues describe Warren as someone who values practical courtroom skills and the traditions of civil practice. He balances participation in professional groups with day-to-day case work at his firm. Over the years he has handled matters that require courtroom presence, preparation of witnesses and coordination of trial teams, relying on experience accumulated since his early years as a lawyer.
Outside of professional associations, Warren’s education and long-term residence in Pennsylvania have kept him rooted in the region’s legal community. He takes part in the continuing discourse among trial lawyers and bar colleagues, attending events and contributing to discussions where practice issues are debated.
He continues to practice law at Warren McGraw & Knowles LLC, licensed in Pennsylvania and active in trial-oriented bar groups. His current practice remains based at the firm where he carries on litigation work in the state.
