About Matthew M.
Matthew M. Rundio's academic path began in the sciences. He earned a B.S. in Biology at the University of Illinois at Urbana-Champaign in 1997. He then turned to law and received his J.D. from Loyola University Chicago School of Law in 2000. The combination of a science background and legal training shapes how he approaches complex factual disputes.
He practices in Illinois and in the federal court system. He is admitted to the Illinois bar and to the United States District Court for the Northern District of Illinois, where he holds general bar privileges. Those admissions allow him to take cases in both state and federal venues when the facts and law require it.
Rundio is a partner at Cavanagh Law Group. In that role he handles courtroom work and case preparation. His membership list underscores a litigation orientation: he belongs to the Chicago Bar Association, the Illinois State Bar Association, the Illinois Trial Lawyers Association, the Association of Trial Lawyers of America, and the American Bar Association. Membership in those organizations keeps him connected to trial practice updates and local court developments.
Colleagues describe him as methodical in building a file. His scientific undergraduate training helps when evidence turns technical. He approaches expert reports and technical testimony by trying to identify the key factual questions early. That approach shapes how he structures pleadings and prepares witnesses for depositions and trial. He balances detailed preparation with attention to how the narrative will read in court.
Over the years he has handled matters that required appearances in both Cook County courts and federal court in Chicago. He has experience managing discovery, arguing motions, and presenting evidence to factfinders. He often coordinates work among co-counsel and experts when cases bring together multiple technical and legal threads.
Outside the courtroom he stays involved in the legal community through continuing legal education and association activities. He uses those forums to track developments in procedural rules and trial practice. That ongoing engagement feeds back into how he prepares cases and advises clients on litigation strategy.
His current practice focuses on litigation in Illinois state and federal courts.
