I have worked in Ireland, the UK and Australia, in acute hospitals and primary care settings in many different specialties such as Gastrointestinal Disorders, Cardiovascular Risk Reduction, Autoimmune Disorders and Research, and more recently in the area of the Microbiome. My specialty roles in nursing led to my passion with nutrition.

I am a passionate Gut Health Advocate, Registers Nurse (ABA/NMBI) & Registered Nutritional Practitioner (NTOI), who has been on a number of journeys with my own health & why I understand the journey most of my clients face.

What Our Clients Are Saying
"After many months of pain and suffering, I sought help from Sinead, who offered full support, guidance, and loads of informative advice and information. And so, I started on my journey back to feeling myself again through natural remedies. I'm sleeping better, eating healthier, and loosing weight, especially my menopausal belly fat. I'm calmer and my brain fog has cleared, all through the nutritional guidance from Sinead."
