Marie Stopes UK Nurses

No two careers in nursing are the same and working in the independent sector for a specialised service can be a fantastic alternative to working for the NHS. Whether you have recently qualified as a registered nurse or are looking for the next step in your career, we’re always looking for passionate people to join our charity in the UK.
