How our team works

We strongly believe that our patients receive the best care when we work together as a team. The organisation of our clinical team reflects this. The team consists of doctors from a range of specialties, including surgeons, anaesthetists, oncologists, radiologists and pathologists, as well as nurses, dietitians, physiotherapists and administrative staff. The core team members are shown below.

Our approach means that our patients may be treated by any of the team members. Therefore, if you are a patient, you may see different doctors at different points in your journey. For example, you may see Mr Barham in clinic, and may have surgery under the care of Mr Titcomb. Organising our team this way allows us to make sure that we provide 24/7 specialist care, and helps us to share the workload within the team to minimise waiting times for treatment.
