About

Three decades of care, one clear philosophy

SYAN was founded by Serhii Shcherbyna, a wellness practitioner whose work began with a certification in therapeutic massage and manual therapy in 1993. Over thirty years, that hands-on foundation grew into an integrated practice that pairs bodywork with structured, science-informed nutrition and lifestyle coaching.

Arriving in Ireland under temporary protection, Serhii built SYAN to serve a community he understands first-hand — offering trusted, native-language wellness to Dublin’s Ukrainian and Russian-speaking diaspora, alongside a discerning private clientele who value discretion and depth.

The philosophy is simple and honest: lasting wellbeing isn’t built from dramatic gestures, but from small, repeatable habits — across sleep, food, movement and recovery — that compound over years. It’s the same idea that runs through The Longevity Code, and through every session.
