SAPA was founded in 1993 in the US as a non-profit organization and since then has grown rapidly and become one of the most active and well-recognized professional organizations in the US with a membership base of over 4,000. SAPA is headquartered in the Greater New York area (NJ/NY/CT) with five regional chapters (SAPA-NE in New England, SAPA-GP in Greater Philadelphia, SAPA-CT in Connecticut, SAPA-MW in Midwest area, and SAPA-West in West Coast), and one chapter in China. SAPA members are engaged in drug discovery, pre-clinical & clinical development, manufacturing, regulation, marketing, and distribution of pharmaceuticals and biotech therapeutic products. To fulfill its missions, each year SAPA and its regional chapters organize/sponsor many events including the SAPA annual conference, scientific symposia, seminars, workshops, and social activities both in the U.S. and China. These events have been supported and sponsored by many organizations, including major pharmaceutical, biotech and CRO companies as well as many Bio-Parks and Development Zones in China.
