Are you trying to conceive or optimise your fertility?

Managing PCOS, endometriosis, or a hormonal condition?

Looking for evidence-based nutrition support tailored to your health goals?

Celeste is an Accredited Practicing Dietitian (APD) specialising in fertility, reproductive, and metabolic health.

Celeste works with women who are trying to conceive, managing PMOS (formerly PCOS) or endometriosis, navigating unexplained infertility, or preparing their bodies for IVF and assisted reproductive treatments. Her approach is evidence-based, food-first, and built around sustainable lifestyle change rather than short-term fixes.

Research shows that diet is a contributing factor in up to 46% of infertility cases, yet nutrition is consistently underutilised in fertility care. Celeste bridges that gap, working alongside GPs and fertility specialists to provide targeted nutrition support that complements medical treatment.

Beyond fertility, Celeste provides nutrition education and coaching to men and women with chronic disease, metabolic, and hormonal health conditions.

Whether you have been referred by your GP, a specialist, or are self-referring. Celeste provides practical and individualised nutrition strategies tailored to where you are in your health journey.
