A personal story
behind the practice

I'm a wife, mother of two and Registered Nutritional Therapist with a passion for helping women navigate hormones, motherhood and the demands of modern life.

In my early twenties I was diagnosed with PCOS, years of missing periods, acne and severe PMS. Through nutrition and learning to support my body, I was able to restore my health and regain balance. That experience became my purpose.

After the birth of my second child, a prediabetes diagnosis deepened my understanding of how closely hormones, blood sugar, stress and emotional wellbeing are all connected.

Today I support women with hormonal health, fertility, pregnancy, postpartum recovery, energy and digestion, combining personalised nutrition, functional testing and practical lifestyle support.

02
