The future of wellness has arrived – The Longevity Retreat is here.
South William Clinic is bringing medicine, luxury and next-generation wellness together for Ireland’s first medically-led longevity retreat.
The award-winning medical aesthetics group is bringing luxury wellness and medicine together to create an exclusive event this autumn.
The Longevity Retreat is as an immersive two-day experience taking place in the beautiful The Reserve at Killashee in Naas, Co. Kildare on Saturday 24th – Sunday 25th October 2026.
It’s time to make wellness retreats about far more than switching off.
More than a wellness retreat
This high-end retreat is more than a traditional wellness escape. It’s that – and SO much more.
This must-attend two-day event brings together advanced health screening, longevity medicine, cutting-edge wellness technology, medical expertise, movement, nutrition and restorative therapies in one expertly curated weekend.
It’s not only about living longer… but living better.
Hosted by South William Clinic founder Brendan Molloy, the Longevity Retreat wants attendees to do more than simply treating problems when they arise and instead, understand their bodies more deeply from the inside out.
South William Clinic launched this retreat in August, inviting Ireland’s top wellness and beauty creators including Jess Redden, Ashley O’Dubhain, and Thalia Heffernan to enjoy the experience first hand.
And it’s safe to say they were impressed.
The programme
The programme includes a range of diagnostic and health assessments, including:
Comprehensive blood screening

And then there’s the location – the beautiful, intimate Reserve at Killashee where guests will relax in private accommodation and indulge in a nourishing menu over the weekend.
It’s time to start understanding your body better, and putting yourself first, at this one-on-a-kind intimate retreat.
The conversation around ageing is changing
Instead of asking simply how we can live longer, the question is increasingly becoming: how can we stay healthier, stronger and feeling like ourselves for longer?
South William Clinic Founder Brendan Molloy says: “For us, longevity is about helping people become more proactive about their health.
“We want guests to leave understanding their bodies better, feeling fantastic, and with practical information they can take into everyday life. It is where medicine, wellness and lifestyle come together.”
