Meet the DoctorDoctor team

Leadership team

Nic has been involved with DoctorDoctor – formerly known as the Australian Locum Medical Service (ALMS) and the Medical Deputising industry for more than 20 years. Appointed as the Manager of the business in Melbourne in 2000, he was appointed as Chief Executive Officer in 2007, a position held until the company was acquired by Sonic Clinical Services in 2013, at which point the role was redesignated as Chief Operating Officer until 2015 when he was appointed as General Manager.

Nic played a key role in the formation of the GP Deputising Association (GPDA) in 2017 and is the current Vice President and Secretary. The GPDA is an association of healthcare stakeholders working to improve conditions within the healthcare industry related to the provision of after-hours healthcare, including Medical Deputising Services acting for and on behalf of General Practice, General Practitioners and their patients. The organisation works together with other stakeholders like the RACGP, the AMA, GPs and other primary health care providers, to promote innovative and ethical models of after-hours healthcare delivery focused on safety, quality improvement and the appropriate use of scarce healthcare resources.

She is currently working as a Melbourne Deputising GP and has over 15 years’ experience as a Deputising Doctor. Her main interests involve Aged and Palliative Care.
