Alec is an associate in our Energy and Natural Resources Practice and our Climate and Sustainability Practice, based in our Belgium office.

Prior to joining Oliver Wyman, Alec has four years of working experience in management consulting and completed internships at a global leader in additive manufacturing and an NGO in Kenya.

He has helped clients with strategic cost reductions, business reorganizations, and operational post-merger integrations (PMIs). His growing passion for sustainability has led him to focus more on climate-related projects, primarily supporting clients with climate strategies and decarbonization pathways.

A well-executed climate strategy not only helps our clients reduce their environmental footprint but also sets an industry example that strengthens their competitive advantage

What makes his work inspiring is his ability to shape corporate strategies, support companies to embark on their climate journey and equip clients with the necessary means to implement strategies.

In his free time, Alec enjoys cycling, running, and hiking.
