Our Clinic GPs

You have a choice of treating doctor from our team of doctors who work on a casual basis at the after-hours clinic. Each one is very broadly trained and experienced and motivated to assist. The mix of skills also allows us to offer wide range of medical services including contraception and mental health.

Each doctor is credentialled by the Clinical Committee of DHSA and undertakes the annual one-day educational update in addition to their usual Continuing Professional Development with their respective Colleges (RACGP and ACRRM).

Due to the part-time nature of the after-hours service, our doctors work between one and two sessions each month at the clinic and each doctor performs their own personalised follow-up of test results. If this is not possible due to absence on leave or whilst overseas, results and actions are confidentially followed up by the Medical Director.
