Leadership
Making yourself subordinate to your team, holding each other accountable, and taking responsibility are not givens, even when they are beautifully incorporated into your core values. To address these crucial leadership elements, Ray Klaassens, Sierd Nutma, and Onno van Boven founded the Leadership Centre of Triangular Group (TGL) in 2022. All our programs are guided by inspiring and experienced facilitators, often with backgrounds in the Dutch Special Forces.
