Profile

A consultant who makes
compliance defensible.

01 / Profile

I sit at the intersection of regulation, data and supply chains. My work is translating the unforgiving language of ESG, REACH, RoHS, Prop 65 and Conflict Minerals into clear, repeatable programs that survive an audit and a board review alike.

Having led compliance initiatives for global supply chains and Fortune 500 companies, I specialise in reducing risk, lifting supplier response rates and driving genuine sustainability outcomes. I have built and run programs spanning North America, Europe, Asia and Africa, always with the same intent: fewer surprises, cleaner data, stronger evidence.

The result is compliance that is not a fire drill, but an operating discipline.
