Does you suffer from PCOS or Enometriosis?

Need a tailored nutrition plan?

Discover your tailored fertility diet with an expert Fertility Dietitian.

Feel empowered to make lasting changes to your lifestyle, so you can better understand how these changes impact your reproductive health and well-being.

Celeste is an Accredited Practicing Dietitian and Nutritionist with a holistic and inclusive approach that enables her to create meaningful lasting connections with her patients and to support them in creating sustainable lifestyle changes to improve their health and well-being.

One of the most overlooked components of fertility is good nutrition.

Celeste works with individuals and couples who want reliable and proactive nutrition coaching to help them optimise their diet for fertility success and uses a food-first approach to managing women’s health concerns such as Polycystic Ovarian Syndrome (PCOS), Endometriosis and lost menstrual periods.

Targeting your nutrition to boost your fertility is the most underused resource in the fertility space. Studies have shown that a sub-optimal diet is a leading cause in 46% of infertility cases, yet nutrition is often overlooked when trying to conceive.

With experience working at the Royal Women’s Hospital in Melbourne and specialist fertility and pregnancy practices, Celeste has a love for supporting women through their pre- and post-conception phases. She does this with simple, dependable, nutrition advice, which can help you to cut through the confusing and outdated nutrition information to significantly improve your chances of conception and go on to have a healthy pregnancy and baby.

Celeste is passionate about helping you to feel prepared, empowered and excited to use your diet to your advantage and help you reach your goals whether it’s improving your health, managing chronic health concerns optimising your fertility and preparing your body for pregnancy.
