General practitioners have a wide range of medical knowledge, and are often the first point of contact for patients. They are key to helping patients monitor their health status, manage health conditions and promote wellness.

When findings of tests and examinations need further investigation, specialists offer advanced treatment options and work closely as a team with our healthcare professionals for personalised care delivery.
