About the OWN Clinic

Hello and thank you for your interest in Orla Walsh Nutrition. 

After working in a number of hospitals across Ireland and the UK, Orla Walsh founded Orla Walsh Nutrition (O.W.N.) in 2011. Orla’s ambition was to create a clinic in which well respected, highly skilled Registered Dietitians could work from. 

Over the years, the clinic has become renowned as one of Irelands leading and most trusted general dietetic and nutrition practices. Orla and her team pride themselves on providing the most up-to-date, evidence-based, practical advice.

Our Registered Dietitians provide clear and jargon-free advice on topics including (but not limited to):

  • Fertility
  • Weight Management
  • Heart Health
  • Hormone Changes (e.g. PCOS, Thyroid, Menopause)
  • Gut Support
  • Paediatrics
  • Sports Nutrition

Although each Registered Dietitian brings their own unique personality and skill set to the practice, there is a consistent approach to how we do things. A person-centred approach is applied to offer practical nutritional solutions that are tailored to the person’s individual needs and circumstances.
