About

A branch of the non-profit Parenteral Drug Association (PDA), the Delaware Valley Chapter serves as a forum through which technical professionals in Pennsylvania, Delaware, and Southern New Jersey advance the science of development, manufacturing release and marketing of parenteral pharmaceuticals, biopharmaceuticals, and chemicals.

Our chapter hosts regular networking events that feature presentations by thought leaders in R&D, Manufacturing, Quality, and Regulatory Affairs. Our meetings provide opportunities for members to make new connections and to hone their technical expertise through interactive discussions. We curate the presentations, reports, and white papers contributed by our experts in our "Knowledge Center", a digital database which can be referenced by all of our members. In addition, our chapter aggregates and publishes job opportunities from across the industry. Finally, our chapter invests in the next generation of scientists by endowing scholarships for primary school students in nearby Philadelphia.

Founded in the 1990’s, PDA Delaware Valley is a regional chapter of PDA that serves technical professionals in Pennsylvania, New Jersey, and Delaware. As a community of leaders from different functional areas, our chapter embodies the PDA’s mission of “Connecting People, Science, and Regulation:”

People – Networking events that attract core companies, vendors, and academic institutions
Science - Expert-led roundtables and symposiums on industry best-practices
Regulation - Peer-Reviewed White Papers and Technical Reports on FDA guidelines

A non-profit organization, PDA Delaware Valley donates a majority of our profits to impoverished school districts in our community. Please check out the Community Outreach section to learn more about our charitable contributions.
