Southeast

Pennsylvania

A map of Pennsylvania split into six regions. The Southeast region is highlighted and separated, and its counties are indicated on the map.

Big ideas don’t stay on paper in Southeast Pennsylvania. They get tested, funded, manufactured, and brought to market. Across five counties, companies are building the future of medicine, technology, and advanced manufacturing in one of the nation’s most connected innovation ecosystems.

Philadelphia anchors the region as one of the country’s leading centers for life sciences, healthcare, research, and biomedical technology. That momentum is reflected in the level of investment flowing into the region. Johnson & Johnson is investing more than $1 billion in a next-generation cell therapy manufacturing facility in Montgomery County. GSK is developing a $1.2 billion biologics flex factory in Upper Merion, while TerraPower Isotopes selected Philadelphia’s Bellwether District for a $450 million radioisotope facility focused on cancer-fighting treatments. Ranked among the top 10 life sciences hubs in the United States, the region combines renowned universities, future-forward healthcare systems, deep venture and institutional investment, and a growing community of cutting-edge startups—all working together.

A strategic East Coast location.

Global markets within reach.

Southeast Pennsylvania gives businesses direct access to some of the largest consumer and business markets in the world. Located in the center of the Northeast Corridor, the region places companies within reach of major metropolitan areas including New York City, Washington, D.C., and Boston while providing logistics access to international markets.  The Port of Philadelphia is consistently ranked among the top-performing ports in the country and is part of a statewide port network moving approximately 67 million tons of goods annually, representing nearly $50 billion in value, offering businesses the operational capacity needed to scale.

That infrastructure is matched by a strong and highly educated workforce pipeline. Institutions including the University of Pennsylvania, Drexel University, Temple University, as well as community colleges and technical training providers, supply talent across life sciences, engineering, advanced manufacturing, and technology. Workforce development organizations like Life Sciences Pennsylvania help employers connect directly with skilled workers prepared for careers in rapidly evolving industries.
