General Practitioner
Clara graduated from her medical studies at the University of Sydney and has been working in General Practice since 2006.
Clara is passionate about being proactive in her approach to medicine. She has had a keen interest in preventative health care since she was a junior doctor. In her time as a general practitioner, she has witnessed the inadequacies of the current reactive-focused healthcare system and its failure to address the root cause of many health conditions. Since discovering the use of lifestyle as medicine, she has been training intensely to learn how she can empower her patients to optimise their health in a holistic way.
She finds real joy in her work when she sees her patients achieve their health goals, whether that be sustainable weight reduction or reversing their chronic health conditions, such as type 2 diabetes. She is excited to be a part of the multi-disciplinary team at Oracle Healthcare to maximise the opportunities for excellent long-term health outcomes for her patients.
Outside of work, Clara enjoys European-style board games, escape rooms, nature photography, geocaching, being outdoors and running – you can be sure to find her at her favourite park run every Saturday morning.
