GSK has a significant footprint in the US across commercial, R&D, manufacturing, and corporate functions.  

  • We employ ~15,000 people across the US
  • Our largest US-based operation, the Upper Providence R&D hub features 8 smart labs and more than 3,000 GSK people discovering and developing new medicines which will change lives.  
  • We also do Research & Development in Boston, Massachusetts, San Francisco, California and Rockville, Maryland. 
  • We have manufacturing sites across the US, including sites in Rockville, Maryland, Upper Merion, Pennsylvania and Zebulon, North Carolina producing medicines to treat diseases such as multiple myeloma, severe eosinophilic asthma, lupus, and HIV and a manufacturing site in Hamilton, Montana contributing to vaccine manufacturing.
  • We have two commercial hubs in Durham, North Carolina and Philadelphia, Pennsylvania. These hubs feature modern, flexible workspaces that provide a hybrid solution to remote and office working – offering our employees opportunities to balance work and home life by creating schedules that flex to personal and business needs.  


The United States is a key market for GSK, with sales in 2021 of $12 billion

Over the last 3 years we have brought several important new innovative medicines to patients in the US. including treatments for oncology (Blenrep & Zejula), HIV (Apretude), and Covid (Sotrovimab).  

We operate responsibly for all our stakeholders by prioritizing Innovation, Performance and Trust.  

We are working closely with our colleagues in R&D at our site in Upper Merion, Pennsylvania by investing in state-of-the-art manufacturing to deliver innovation and medicines (JEMPERLI and Depemokimab) to patients more quickly.

Creating a culture where individuals and teams thrive

We are also transforming our culture to create an environment where individuals and teams are inspired to be ambitious for patients, accountable for impact, and to do the right thing, for each other, our communities, society as a whole and always for the patients we serve. Diverse perspectives lead to fresh, innovative ideas. We’re building an inclusive culture where the world’s talent can help transform medicine, together.

  • We have improved diversity, equity, and inclusion by recruiting and appointing diverse talent that mirrors the communities in which we live, work, and serve. By the end of 2021, 27.1% of senior leaders in the US. were ethnically diverse, (which was up from 23.2% in 2020). This represents great progress towards GSK’s aspiration of at least 30% ethnically diverse leaders in roles at VP above in the US by 2025.
  • We have made a 10-year, $10 million investment to increase the number of Black, Latinx and female students in Philadelphia who become STEM professionals.
  • We want to access the next generation of talent and ideas by continuing to situate our U.S. hubs near some of the country’s leading universities.
