About Tammy
Clinical Nutritionist (BHSc) & Certified Fertility Specialist
If you're here, you're probably done with the overwhelm, the conflicting advice, and the feeling that something is being missed. You deserve more than generic guidance. You deserve a practitioner who looks at your whole picture and walks alongside you every step of the way.
That's exactly what Tammy Shemesh offers.
Tammy is a clinical nutritionist holding a Bachelor of Health Science in Nutritional Medicine, a certified fertility specialist, eating psychology coach, yoga instructor, and trained postnatal doula, specialising in supporting women and couples from preconception through pregnancy and into postpartum.
She gets it personally, too
As a mother of two, Tammy brings more than clinical expertise to her work. She understands the emotional weight of a fertility journey, the challenges of prenatal nutrition, postpartum recovery, and breastfeeding firsthand and that lived experience shapes everything about the way she shows up for you.
She combines clinical precision with genuine emotional care, works collaboratively alongside your GP, fertility specialist, acupuncturist, or doula, and believes your biology is not separate from your story. Rather than chasing symptoms or handing you a rigid plan, she co-creates a personalised strategy that brings you back into trust with your own body.
What Tammy helps you with
Every woman who comes to Tammy arrives with her own unique story. There's no one-size-fits-all approach here. Personalised support tailored to exactly where you are.
