KEYNOTES 2026

John Tros is Senior Vice President Operations and a member of the Executive Management Team at BME Group, one of Europe’s leading building materials distributors. BME operates more than 940 locations across eight countries and serves approximately 275,000 customers. John leads the Group’s procurement, supply chain and logistics agenda, strengthening operational performance in a market shaped by volatility, complexity and constant change. He also leads BME’s Environmental Taskforce, helping customers make more informed choices about sustainable building materials.

Before joining BME, John spent nearly a decade as an Advisory Partner at KPMG, leading complex transformation projects. His experience includes work on the integration of Ahold and Delhaize, Shanks and Van Gansewinkel, and Schiphol’s asset strategy. He combines a PhD in Purchasing Management with a practical, hands-on leadership style and a proven ability to translate strategy into sustainable operational results.

At BME, John has played a central role in realising synergies, strengthening supply-chain resilience, accelerating data-driven decision-making and building a more agile operating model. He is particularly focused on achieving the right balance between central direction and local entrepreneurship. Drawing on the dilemma-reconciliation approach developed by Dr Fons Trompenaars, he helps organisations turn competing priorities into practical, sustainable solutions.

The Royal Netherlands Naval College’s motto, “Kennis is macht, karakter is meer” (“Knowledge is power, character is more”), continues to shape his leadership philosophy. He believes that lasting transformation depends not only on technology, but above all on people, effective change management and an unwavering focus on solving real business problems.

Jeroen de Lange is Director Supply Chain Benelux at Mediq, one of the leading providers of medical devices and healthcare solutions in the Netherlands.

Throughout his career, Jeroen has worked in complex healthcare environments and has played a key role at Mediq in strengthening integrated planning and creating greater visibility and control across the company.
