Ernst (Sigi) Siegenthaler
CEO / Consulting Engineer

Even after my many years of work and experience with a wide variety of projects and tasks in controlled diamond dismantling technology, my enthusiasm for it is still unbroken and very lively.

The variety of challenges in this area motivates me again and again to find the best possible solutions for special requirements.

Transmission of know-how is also of central importance to me in order to make the impossible possible in a future-oriented way.
