Working Life: 'Good public health relies on the collective efforts of society'

“When people think about health, they often think about hospitals, medical care, or treatment, but much of what determines our health happens long before we step into a GP surgery or hospital. That understanding ultimately drew me to a career in public health.

“Originally from Co Armagh, I completed my undergraduate degree in medicine and, after working in hospital settings, trained and practised in the community as a general practitioner. During those early years working across primary and secondary care, I developed a strong appreciation for the vital role of prevention and early intervention in keeping people well, alongside the importance of treating illness.

“I saw how many of the health challenges people face are shaped by factors beyond the health service — things like housing, employment, education, commercial influences, or access to supportive environments for health.

“These factors do not affect everyone equally and can lead to important differences in health outcomes or health inequalities. This highlighted for me the importance of working together across health and other sectors to address these wider determinants of health, reduce inequalities, and give everyone the best possible opportunity for health and wellbeing.

“I later completed clinical academic training with a focus on health improvement, which deepened my appreciation of the role of scientific evidence in shaping health improvement. This ultimately led me to pursue a career in public health. I now work as a consultant in public health medicine with the HSE, specialising in health improvement.

“Good public health relies on the collective efforts of society.

I have always valued the opportunity to work with colleagues and communities, all of whom contribute to a shared goal of improving health and addressing inequalities.

“Public health involves gathering and interpreting evidence and applying the best available science and practice to improve and protect population health, from local to global levels.

“Outside of work, I like to stay busy — thankfully, as I have young children who make sure of it. Family time is especially important, whether simply sharing a meal together or going for a walk. These moments help me switch off and recharge.”
