Charlene S. Seibert


Charlene is a member of the Professional Liability Department, where she dedicates her practice to the defense of attorneys and other professionals. Primarily, Charlene defends attorneys in legal malpractice actions covering a wide range of practice areas, including medical and dental malpractice, real estate and title insurance, estate and probate matters, divorce and support, complex business transactions and commercial litigation. Additionally, Charlene represents attorneys sued for intentional conduct arising from their representation of a client, including claims of defamation, abuse of process and statutory claims for wrongful use of civil proceedings. In cases where a lawsuit has not yet been filed, Charlene has served in a claims avoidance capacity, including navigating through conflicts of interest that may arise through the course of a lawyer's representation and undertaking mitigation efforts to salvage underlying litigation or otherwise reduce potential damages.  As well, Charlene has assisted counsel in responding to disciplinary complaints made against them with the Pennsylvania Disciplinary Board.  She is also an active member of the Pennsylvania Bar Association Professional Liability Committee and the Allegheny County Bar Association Professional Liability Committee, where she frequently addresses prominent lawyer liability and insurance issues, and is a frequent speaker on topics of legal malpractice avoidance.

Charlene began her practice representing lawyers and other professionals in 2006, after graduating in the top 10% of her class at the University of Pittsburgh School of Law.  Through law school, Charlene served on the executive board for the Pittsburgh Tax Review as the articles editor where she ensured the accuracy of legal propositions asserted by tax professionals and improved the authors' writing techniques. Also while in law school in 2004, Charlene joined Marshall Dennehey as a law clerk and upon graduation continued with the firm in the Professional Liability Department. 

Prior to law school, in 2002 Charlene graduated from John Carroll University, magna cum laude, where she obtained her Bachelor of Arts degree in Political Science. She was inducted into Pi Sigma Alpha Political Science Honor Society and awarded the Kathy L. Barber Outstanding Scholar Award in Political Science for graduating seniors. Also during her time at John Carroll, Charlene served as an intern for the U.S. Export Assistance Center in Cleveland, Ohio, a division of the United States Department of Commerce, where she assisted small and medium-sized businesses with regulatory compliance issues and market research relating to the exportation of goods.
