ODS’ connection to the not-for-profit world stems from the experiences of its team members. Aside from being respected consultants, each of the team members has previously worked in the not-for-profit sector, both in Brussels and internationally. For each project, we determine together with the client which of our colleagues are the best fit for the job and the organisation.
