Grey is highly skilled in identifying business opportunities, diagnosing constraints and uncovering the root causes that limit growth, productivity and profitability. As the former Head of Consulting at the National Productivity Institute, he uses a range of practical diagnostic tools and business improvement methodologies to ensure that challenges are identified early, root problems are properly defined and practical opportunities are revealed.
Over the course of his career, Grey has worked extensively in MSME development, private sector development, business linkages, productivity improvement, competitiveness enhancement, export development, business turnaround, capacity building and strategic planning.
His experience includes working with development agencies, chambers of commerce, export councils, public sector institutions and private businesses across multiple sectors.
Grey holds a Bachelor of Commerce in Economic Sciences and a Master of Business Leadership. His ability to combine strategic thinking with practical implementation makes him a trusted advisor to entrepreneurs, business owners, project teams and institutional partners.
At Global Mark, Grey continues to play a critical role in guiding business owners to understand their constraints, unlock opportunities and build stronger, more competitive and sustainable businesses.
