We are a training practice and one or two general practice registrars are based at the practice. The registrar is an experienced doctor intending on specialising in general practice. He or she will be working closely with the team and will ask for advice from their colleagues if needed.

Locum Doctors

From time to time we employ locum doctors to cover for periods of partner absence. These doctors all have passed the MRCGP exam and we try to use the same doctors. We encourage you to see these doctors and not to wait for the return of your own doctor.

Nursing Team

Practice Nurses

Our practice nurses are available every day, by appointment. You can ask the receptionist for an appointment to see the nurse without seeing the doctor first, but the nurse may need to consult a doctor about your problem if your condition requires it. Our nurses are qualified to deal with minor injuries, dressings, ear syringing, leg ulcers, sprains, BP checks, cuts, vaccinations (and advice), childrens’ immunisations (we provide a full immunisation service for babies and children), cervical smears, etc. They run Well man and Well Women clinics and help look after patients with long term illnesses, including asthma, heart disease and diabetes. They can organise tests for diabetes, blood pressure, cholesterol and many other conditions and can offer advice on diet, healthy living, alcohol, smoking, minor illnesses and family planning.

Community Nurses

Community nurses attached to the practice visit patients who are confined to their homes and need nursing assistance. This may be arranged with the doctor. The hospital will normally arrange for a community nurse to call on these patients discharged early who still require nursing treatment at home.

Health Visitors

The health visitors can give advice on healthcare, particularly for expectant mothers, small children, the elderly and the handicapped. If you have a problem affecting your health she can put you in touch with sources of help. The health visitor may be contacted at the surgery on Tuesday afternoons, and at the Wilson Clinic at other times by phoning 020 8687 4722.

Physician Associate

Physician Associate

Physician Associates (PAs, previously known as Physician Assistants) are clinicians who follow a postgraduate training course. The first course was set up at St George’s hospital several years ago. Dr Chana was involved in setting up the course and Dr Paterson is a course director involved in teaching the PAs.

Physician Associates can take histories, examine, request investigations, make diagnoses and recommend treatment. They work under supervision of GPs if they need a second opinion. We are currently looking to recruit a new PA.

We also train PA students in the practice.

The receptionists are here to help you and to ensure they can assist you as efficiently as possible. They may need to ask for further details or check information in your medical records when you telephone the surgery. They are bound by the same rules of confidentiality as the doctors and nurses. Please appreciate that receptionists are not qualified to discuss your clinical care but they will do their best to point you in the right direction.
