Art is a member of the Professional Liability Department where he concentrates his practice in professional malpractice and focuses primarily on the defense of claims made against government entities, real estate professionals, architects and engineers.  He has obtained favorable outcomes for his clients both at mediation and at every level of court in Delaware.

Prior to joining Marshall Dennehey, Art served as Delaware corporate counsel for a multi-state real estate title company.  He has conducted hundreds of Delaware real estate settlements and has successfully represented real estate professionals in a variety of matters.

Art's managerial experience gives him a unique perspective into the defense of professionals and directors and officers.  For instance, while in business school, he served as director of Global Lawyers & Physicians, a health and human rights non-profit organization based in Boston, where he expanded the organization's membership, raised funds and helped to lay the groundwork for creation of the Boston Refugee Center for Health and Human Rights.
