Advisory Board

Competence group of excellence

Our medical advisory board consists of highly qualified physicians from different disciplines. Each of these experts advances the product development and quality assurance of the VSI in their own respective area. This provides the advantage that impulses, needs and challenges can be recognized right away and solutions implemented at an early stage.

It is particularly important for us that our VSI solution is directly defined by the individual user areas. Thus it generates an additional value for our customers right from the start. Our solution is driven by the added value for our customers, not by technology. It is the task of the medical advisory board to ensure our promise.
