Since joining NJ Sharing Network in 2011, team members have relied on his expertise in providing information and education on trends and best practices. David’s current role encompasses crucial elements of the organization’s clinical operation, including analyzing data and resources to maximize the number of organs recovered and increase authorization rates. His leading role in regulatory compliance and performance improvement ensures NJ Sharing Network’s continued growth as a top performing Organ Procurement Organization (OPO).

David has presented at numerous national meetings including a plenary session at the 2010 National Learning Congress where he highlighted the advantages of using automated web-based dashboards in transplantation. He has published papers in the fields of Microbiology, Immunology and Transplantation, including an article in the Journal of Neurology showing the impacts of prolonged brain death intervals on authorization, donor management, organ yield and end of life care.

David began his career in Halifax, Canada, where he led recovery teams throughout the Atlantic Provinces facilitating tissue and eye recovery, processing, distribution, and organ preservation. After moving to Manhattan in 2004, David joined the New York Organ Donor Network, where he supervised the call center, approached donor families, and guided the organ allocation process.
