About us

Triangular Group was founded 5 years ago by two former officers of the Dutch Special Forces and intelligence service. Their goal is to allow talented individuals from the security domain - after their career with the Dutch government - to continue to contribute to the safety and resilience of others through advice, support, and the sharing of knowledge - 24/7 and worldwide.

Ray Klaassens is a Managing Partner and co-founder of Triangular Group. Until 2014, Ray was active in various operational government positions for more than twenty years. In this period, he led teams of up to 80 people and managed complex projects in challenging areas. 

Onno van Boven is the other Managing partner and co-founder of Triangular Group. Until its establishment in March 2014, Onno served in the Dutch Special Forces and intelligence services of the Dutch government for nearly two decades. Onno has substantial experience with conflict areas and training specialists.

In addition to Triangular Group, Ray and Onno established the foundation Commando & Family Support . Command & Family Support (CFS) is committed to (former) colleagues from the field of Dutch Special Operations, whose personal situations need support.

The goal of our courses is to truly prepare students for reality. That is why I strive to provide the highest possible quality education.
