About Mr. Jonathan Neal
Mr. Jonathan Neal Portner began his academic path in political science at Franklin & Marshall College, where he completed his undergraduate studies in 1981. He went on to earn his J.D. from the University of Baltimore School of Law in 1988. Those years set the groundwork for a legal career that spans the public and private sides of practice.
He entered the profession in the late 1980s, joining Gordon, Feinblatt in 1989. He spent the early years of his career there, gaining courtroom and case-handling experience. In 1993 he helped establish Portner & Shure, P.A., and took on the role of managing partner. That move marked a transition from associate work to firm leadership and practice management.
Portner’s memberships reflect the range of his professional interests. He has been a member of the American Association for Justice and the Maryland Association for Justice since 1988. He joined the Million Dollar Advocates Forum and the National College for DUI Defense in 2011 and maintains those memberships. The listings tie him to organizations involved in civil trial practice and in DUI defense education, and they indicate ongoing engagement with peer groups that focus on trial skills and case development.
He is licensed to practice in Maryland, the District of Columbia, and Virginia. Over more than three decades in practice he has handled matters that brought him into state and federal courts across those jurisdictions. His career includes both courtroom appearances and firm-level management responsibilities, a combination that shapes how he approaches case preparation and client representation.
Colleagues and court records show a long-running presence at Portner & Shure, P.A., where he has served in leadership since the early 1990s. He continues to participate in professional associations that provide continuing legal education and networking for trial lawyers and for attorneys who handle DUI matters. He remains active in bar activities and professional groups that address litigation practice.
He currently practices at Portner & Shure, P.A., handling matters in state and federal courts across Maryland, the District of Columbia, and Virginia.
