Nicole Gray

My passion is supporting families.

Whether it is working through the rocky ground of learning and behavioural difficulties and mental health, or improving immunity for the entire family against preventable diseases, my focus is on supporting the family as a whole to work together towards greater health.

I look forward to working with you and your family to help you regain your health so that you can live the life you fully deserve.

To help you rebuild your health, I am combining traditional medicine practices that have been backed up with scientific research to ensure you receive optimal care and achieve your health goals as easily as possible.

In addition to taking a thorough health history, I offer a diverse range of testing to make sure we uncover the root cause of your health issues so that we are not merely addressing symptoms, but actually addressing the underlying drivers of your dis-ease.

I highly value confidentiality and discretion so that I can provide you with a safe and nurturing environment.

My Family’s health journey

Originally from Germany I arrived in Australia in 1998. In 1999 I made Singleton my home and have been very happy here.

Most of my life I have been working in hospitality and have always had a great interest in nutrition, having followed every weight loss diet under the sun with mixed results. This made me realise that there has to be more to it than just going on fad diets and restricting the foods you love.

The catalyst however, for me to study Nutritional Medicine and Naturopathy was mine and my families health. In addition, working as a canteen manager at a public school, I have had insight into the effects of dietary choices on children’s health and behaviour. Countless conversations over the years have made me aware that many are seeking help in taking theirs and their families wellbeing into their own hands but don’t know where to start. I was in the same boat.

After asking many questions and not getting the answers that I felt comfortable with I finally found someone who was able to steer me onto an alternative path to health. My family had some amazing results incorporating nutritional changes, supplementation, exercises and the use of a variety of healthcare professionals.

I feel the knowledge I have acquired through my studies and my life experience will be of benefit to the Singleton community and beyond and would love to share it with families in need.

I am passionate about a holistic approach to your wellbeing and hope that you will allow me to be part of your journey to optimal health.

Yours in health and happiness,
