About Henry J.
Henry J. Donner earned his undergraduate degree from American University in 1966 and completed his J.D. at Villanova University School of Law in 1969. He entered the legal profession at a time of change in the late 1960s and has maintained a long-standing connection to practice and professional groups since then. His academic training gave him a foundation in legal reasoning and courtroom procedure that shaped an ensuing career.
Donner is admitted to practice in Pennsylvania and is also admitted to the United States District Court for the Eastern District of Pennsylvania and the United States Court of Appeals for the Third Circuit. Those admissions allow him to appear in both trial and appellate forums. Over the years he has handled matters that require federal as well as state court work.
He serves as Of Counsel at Kang Haggerty LLC, a role in which he brings experience to the firm's cases and clients. The title reflects a senior advising capacity rather than a front-line partnership role. In that capacity he consults on litigation strategy and regulatory issues, and he collaborates with colleagues on case preparation and client counseling.
Donner maintains memberships in several professional organizations. He is a current member of the American Bar Association and the Philadelphia Bar Association. He also belongs to the Construction Financial Management Association and the National Home Builders Association. Those affiliations align him with both the broader legal community and industry groups that intersect with construction and housing sectors.
Colleagues describe him as steady and practical in handling complex procedural matters and in preparing filings for trial or appeal. He draws on decades of courtroom experience when advising on litigation timelines, evidentiary strategy and motions work. His appellate admissions enable him to take cases beyond the district court when appeals are warranted.
Across a career that spans more than five decades, Donner has balanced courtroom work with advisory roles. He has remained active in bar organizations and industry associations while transitioning into a senior advisory role at his current firm. He currently practices as Of Counsel at Kang Haggerty LLC, concentrating on legal matters for clients in the construction and housing industries.
