About John K.
John K. Conner combines years in federal law enforcement with decades in private practice. He earned a B.S. in Criminal Justice from Northeastern University in 1979 and later received his J.D. from Temple University in 1991. Those classroom years set the stage for a career that moves between investigation and advocacy.
Conner began his professional life as a Special Agent with the Bureau of Alcohol, Tobacco and Firearms. That role put him inside federal investigations at a time when enforcement priorities were shifting and forensic techniques were changing. The investigative work shaped his approach to evidence and procedure. It also gave him a practical sense of how government cases are built.
After law school he transitioned into private practice. In 1991 he served as an associate at the Law Office of Cozen O'Connor. That position introduced him to courtroom practice, client counseling and the business side of a law firm. Over time he applied lessons from his investigative background to representing clients facing regulatory and criminal scrutiny.
He is admitted to practice in Pennsylvania and New Jersey. His practice has included federal investigations, firearms-related matters, regulatory compliance questions and criminal defense. Conner has represented clients in administrative proceedings and in state and federal courts. He maintains memberships in professional associations and stays active in legal circles to keep current on shifting standards and emerging issues.
Today Conner practices from The Conner Law Group, LLC, including a Philadelphia office and a main office. He manages a practice that handles litigation and advisory work arising from investigations and enforcement actions. His work emphasizes careful case preparation and an attention to factual detail developed during his years as an agent. Conner’s current practice concentrates on matters that intersect investigation, regulatory requirements and criminal law.
