Our Team

TheRockGroup team integrates experience and knowledge from people with very different professional and personal backgrounds to aid in the transition to a sustainable society. Because TheRockGroup combines experienced business savvy partners and critical young energetic consultants, we have a well-balanced effective team. Most certainly we have the passion for sustainability in common, with each team member contributing unique skills to achieve our overall goal: a more sustainable economy and society.

With experience in corporate organizations, SME’s, start-ups, knowledge institutes, NGO and government environments in the Netherlands and beyond as a result we are able to collaborate well with a range of different stakeholders. Furthermore, it gives us the capacity to provide the link between strategic business planning and ‘on the ground’-reality.

Together we form the building blocks of an experienced, enthusiastic, informal and well-functioning team.
