Making yourself subordinate to your team, holding each other accountable, and taking responsibility are not givens. Not even if they are beautifully incorporated into your core values.

To make these crucial elements of leadership discussable, Ray Klaassens, Sierd Nutma, and Onno van Boven founded the Leadership Centre of Triangular Group (TGL) in 2022. All services here are led by inspiring and experienced facilitators.

Our facilitators combine in-depth knowledge and pedagogical skills with valuable practical experience as leaders in both the security sector (police and defense) and the business world. This unique mix of competencies and traits enables them to effectively understand and address the dynamics and challenges within the business environment.

The key benefits of our facilitators:

  1. Unique Expertise: In-depth knowledge and practical experience from both the security sector and the business world.
  2. Pedagogical Skills: Proficient in imparting knowledge and facilitating learning processes.
  3. Leadership Experience: Experienced leaders, capable of guiding teams in complex and rapidly changing environments, who know how to inspire and motivate.
  4. Insight into Dynamics: Understanding of the challenges and dynamics within business and corporate environments.
  5. Practical Applications: Focus on experiential learning and action-oriented methods for effective results.

We are Skilled
for life
