Leanne March
General Manager – GP Partners Australia
My focus lies in improving clinical care by translating discoveries into practice, with the ultimate goal of advancing towards a research and digitally enabled organisation supportive of primary care.
I am a transformational leader, driven by my passion for driving innovative change and delivering outcomes. Witnessing the inefficiencies and unsafe practices resulting from a paper-based healthcare system, I became obsessed with improving health outcomes through digital and data-driven approaches, and advocate for building digital health capability and interoperability across the system.
I have more than 30 years’ experience in healthcare, in both clinical and non-clinical roles. My background as a Registered Midwife and Registered Nurse, combined with an MBA and Diploma in Accounting have equipped me with the knowledge and expertise to make a difference to patient outcomes.
Throughout my career, I have successfully led and managed complex projects, and for the past six years, GP Shared Care Programs, including our SA Statewide GP Obstetric Shared Care Program.
