I have spent more than 15 years in green building, carbon accounting and ESG — and I still do the work, not only teach it. I am Director of Project Management & Sustainability at Turner & Townsend, where I lead our Malaysia business. I have also taught as a Visiting Professor at Yonsei School of Business.

That shapes every course I build. I write from live projects — real budgets, real certification deadlines, real arguments with a review team — so you get the thresholds that actually catch people out, the credits that look simple and are not, and honest guidance on where a standard is genuinely ambiguous in practice.

More than 13,000 learners have taken my courses. They cover LEED (v5, v4.1 and v4), WELL, and carbon accounting, and they are built for sustainability professionals, consultants, project managers, architects and engineers — and for anyone entering the field who wants knowledge they can use on Monday morning.
