The Role 

Health and Benefits GB is a specialist centre of excellence in all aspects of health, wellbeing and risk consulting for corporate clients. With more than 200 consultants and support staff, this team represents a significant resource providing services to support the design, financing and management of integrated health solutions that are tailored to meet clients’ needs.
