“I am driven by enhancing people performance within organisations and project teams, by stimulating cooperation, leadership and awareness.”

Diederik joined the Darel team in 2025. With a background in work and organisational psychology and change management, he focuses on strengthening performance to accelerate the energy transition. He integrates change-management theory and practice into the Darel way of working, amplifying our impact across clients and projects. Known for a people-centred style and a sharp focus on behaviour, he links a strategy for people excellence in the energy transition to concrete interventions that bring those behaviours to life. After all, the energy transition isn’t just technical, it succeeds when people change how they work.
