Our History

The Continuously Growing EPS Group

The history of EPS Group begins with the dawn of the CRO business, in 1991. From there, we gradually expanded the scope of our business activities, adding SMO and CSO services, and eventually becoming a comprehensive provider of a broad range of drug development and other support services for the healthcare industry. We began to expand into China and other overseas markets early in our history and are now a valued partner in the globalization of new drug development.
