Across all competency levels — from Intermediate CI to Master Black Belt — spanning every business sector in Ireland and internationally.
Not consulting from a distance — working inside businesses, on the floor and in the boardroom, implementing real improvement across every sector.
Dermot brings the perspective of someone who has sat on both sides of the table — as the practitioner implementing change and as the leader accountable for results.
Delivering Lean training, CI consultancy and Business Excellence programmes to companies of all sizes — from family businesses to global multinationals.
As trainer and project mentor on Ireland's most rigorous post-graduate Lean programme from 2010 to 2024 — shaping a generation of CI leaders.
Manufacturing, pharma, medical device, food, financial services, healthcare, public sector, technology, aerospace, FMCG — the methodology is universal.
"Nothing good comes from doing nothing. The organisations that thrive are the ones that never stop improving — and the ones that invest in their people to make that improvement sustainable."
"Curtailing spending on developing staff to eliminate waste and improve customer experience is a false economy. The cost of not training is always higher than the cost of training."
"A well structured and fully mentored training programme will deliver an ROI of between 350% and 160,000%. Where else will you achieve those results? This isn't aspiration — it's a track record."
