Yvonne O’Sullivan

Yvonne had learned from personal experience that life does not always deal you the best health hand but she truly believes that every single person deserves the chance to be healthy so that they can live a full and happy life.

If you have tried and failed, if you are frustrated and tired of feeling unwell, Yvonne would love to work with you, without judgement or prejudice to find your healthiest and happiest self.

Yvonne specialises in: 

  • Solving complex health issues
  • Chronic fatigue
  • Thyroid Health
  • Autoimmune disorders
  • Cancer support
  • Weight loss and body composition
  • Stress and anxiety
  • Pain & inflammation
  • Digestive health

Finding the underlying drivers behind complex health issues is what Yvonne loves to do. Solving health puzzles, uncovering the clues missed by others and helping to empower others to take control of their own health is what inspires her every day. While mainstream medicine focuses on your health as a system (you see a cardiologist for your heart, podiatrist for your feet etc), Yvonne specialises in ‘general practice’ rather than a condition or system as she believes in a more holistic approach to see the whole person, with systems that interact and where poor health in one system can mean disharmony in another system.  Yvonne believes being dyslexic helps her to see the patterns of health differently and helps her solve complex health issues.

Yvonne studied Herbal Medicine at the University of Newcastle before undertaking science honours research, investigating the quality of natural medicines in Australia. Yvonne has practiced and worked in the natural medicine industry for over 13 years, across a broad range of areas including natural medicine manufacturers, raw ingredients sourcing from all over the world, as well as teaching health professionals and tertiary students in nutrition, chemistry and natural medicine. This industry insight has made her somewhat of a product expert and means she will know exactly which products will work best for you.

Yvonne was also a sales rep for many years , representing sales and technical support for several natural medicine companies and as a result saw the inside of some of Australia’s most successful and well known natural medicines practices. Yvonne could never see herself working in one of these clinics until the day she walked into Mullen Health – and we are so excited to have her on board.

Yvonne has two grown boys, and three grandsons and loves spending time either on the water, near the water or in the water.
