Siobhán O’Donoghue

Background & Experience

Siobhán’s journey into decluttering work began unexpectedly during her psychology research at Trinity College, where she noticed striking correlations between environmental clutter and cognitive overwhelm in her study participants. This discovery prompted her to pivot from academic research into practical coaching, and she spent three years developing her signature room-by-room simplification methodology specifically suited to Irish apartment layouts and family dynamics.

She brings 12 years of professional experience in organisational psychology and residential design to her work at Mindful Spaces Ireland Ltd. Her Master’s degree in Environmental Psychology from University College Dublin—combined with her lived experience of managing small Dublin spaces—gives her unique insight into how Irish homes present distinct organisational challenges. It’s not about rigid minimalism. Instead, she helps people understand why they hold onto things and guides them toward sustainable daily tidying habits that actually stick.

Since founding her decluttering workshops in 2016, Siobhán’s worked with over 2,800 Irish households. Her evidence-based approach combines behavioural science with practical, culturally-aware methods designed specifically for Irish living spaces. What drives her is witnessing the profound mental shift her clients experience when they make intentional decisions about what to keep, donate, or recycle. Her workshops at Mindful Spaces Ireland Ltd now operate across Dublin, Cork, and Galway, with a growing online community of over 5,000 people committed to intentional living.
