Leadership proposition

Clarity when the market is difficult. Capability that lasts after the strategy is set.

Markets change. Customers change. Strategies need to change with them. My role is to bring clarity to the challenge, create a commercially credible direction and build the leadership capability needed to deliver it for the long term.

My experience was developed and tested over 24 years with Saint-Gobain and Jewson, progressing from branch leadership to national, Managing Director and board-level responsibility. I now apply that disciplined corporate toolbox with the pace and directness required by owner-led and investor-backed businesses.
