  1. What education have you undertaken to this point in your career?

My academic and professional development has been anything but linear — and I believe that’s one of my greatest assets. I began with a BA Hons in Communication Studies at Dublin City University, which taught me how to craft messages that resonate. From there, I pursued a Diploma in Sports and Exercise Nutrition, followed by Level 1 Precision Nutrition and a Level 4 qualification in Personal Training & Fitness Instruction. These early steps gave me a practical grounding in health and fitness, but I wanted to go deeper. I later completed an NFQ Level 9 in Advanced Performance Nutrition through The Institute of Performance Nutrition, and a postgraduate qualification in “The Active Female Throughout the Lifespan” at DCU.

I’m currently undertaking an MSc in Food, Nutrition & Health at University College Dublin, where I continue to refine my scientific understanding of nutrition and metabolism. Alongside my nutrition studies, I trained as a Personal, Leadership & Executive Life Coach (Kingstown College), earning EMCC and ICF accreditation. This coaching lens has been transformative — allowing me to apply scientific strategy through the subtle art of behaviour change, strengths-based facilitation, and unlocking limiting beliefs.


2. What experience have you accumulated in the field of performance nutrition?

I’ve worked across elite sport, corporate wellbeing, and community health — always with a focus on translating science into strategy. Currently, I serve as Head of Performance Nutrition for Wicklow GAA, where I lead match-day nutrition programming, deliver education to athletes and staff, and consult on food service provision. I also run Haeloo Nutrition, offering one-to-one consultations, seminars, and tailored nutrition strategies for endurance, strength and team-based athletes.

Previously, I supported the Dublin U20 Hurlers as their Performance Nutritionist and worked as a Corporate Wellbeing Specialist with Zevo Health. My experience also included roles with Liva Healthcare as an NDPP Health Coach, and with the Center for Nutritional Psychology, where I communicated research on the diet-mental health connection. I now work with Vhi, where I co-design tailored wellness solutions for corporate clients using data analysis and strategic insight. My role involves interpreting behavioural trends, identifying barriers to wellbeing, and crafting interventions that are both evidence-based and human-centred. Whether I’m working with athletes or employees, my approach is grounded in nutritional science but delivered through the lens of coaching psychology — helping individuals build self-awareness, leverage their strengths, and achieve meaningful goals.


3. What one piece of advice would you offer aspiring performance nutritionists or sports dieticians?

Don’t be afraid to take the scenic route. The most powerful practitioners are often those who’ve gathered insights from diverse fields — communication, coaching, psychology, sport, and science. Learn the science deeply, but deliver it softly. Strategy disguised as empathy is often the most effective tool we have. Focus on understanding the person in front of you, not just their physiology. When you help someone uncover their own strengths and shift limiting beliefs, you don’t just improve performance — you change lives.
