St George’s, Epsom and St Helier Hospital Group

After years of collaboration and creating closer working ties, Epsom and St Helier University Hospitals NHS Trust and St George’s University Hospitals NHS Foundation Trust formed a hospital group. Jacqueline Totterdell was appointed Group Chief Executive in August 2021.

Gillian Norton, is chair of both trusts and took up the role as Chairman in Common in 2019.

Working as a hospital group allows for more joined-up decision making for the benefit of local people, a larger and more resilient clinical workforce, reduced variation in levels of care, and more access to a wider range of services for our patients.

Epsom and St Helier and St Georges remain two separate trusts but with one executive team enabling us to work closer together and build on our strong foundations.

We already work closely together and run joint services such as the South West London pathology network and we’re building a specialist kidney unit to improve care to our patients.
