Sustainable collaboration

The Triangular Group Academy (TGA) is a strategic partner of the Dutch defence forces, enabling us to contribute to an adaptive military force. We have former staff members return as trainers who are willing to share their years of experience with new personnel.

Knowledge through experience

Whether it is operational experience, teaching skills or leadership – the knowledge and experience of former defence staff are unique and valuable. The TGA brings this valuable knowledge back where it belongs, so it can be used again for education and training. Our trainers are eager to get started within the environment they know so well.

Our trainers tell

Our courses must prepare students for reality. That is why I strive for the highest possible quality.

Rob Smets, Trainer Defence &
Emergency Services

Right from my first meeting I felt part of the TGA family. There is a special sense of solidarity within the team, the atmosphere is open and informal and there is great collegiality.

Marieke Vente, Trainer Defence

Enthusiastic work is underway to teach future shooting instructors to apply proper safety precautions and practices. As a result, they are able to help shooters achieve better results and to make shooters aware of their actions.

Mark van der Mark, Trainer Defence

The start at TGA felt like entering a warm nest for me. Everyone is involved, driven and has the same mindset. In addition, there is an excellent atmosphere and I can fully express myself in my work again.

Ricardo Barrientos, Trainer Defence

Whoever stops improving ceases to be good. We do this as an instructor, but also in the training and courses we provide.

Harald Leeuwis, Trainer Defence

TGA is not only a valuable client to me, but I also feel a sincere connection with all TGA colleagues, a close-knit family that enjoys going for the very best result every day, regardless of the assignment!

Antoine Horsten, Trainer Defence
