MED TRUST - the diabetes expert

About us

Three good reasons that make us your strong partner: idea, advice, and service.*


MED TRUST was founded in 1997 by Silvia and Werner Trenker and has grown strongly in over 70 markets worldwide over the last 25 years. The headquarters of our family business is located in Marz in Burgenland, Austria.


A special focus is on our Wellion brand. With it, we have meanwhile established ourselves worldwide as an Austrian manufacturer of medical devices and in vitro diagnostics for a wide range of health areas - especially for diabetes. We are very pleased that we are considered a competent and reliable partner who is constantly developing through innovative ideas. Our demand for continuity, seriousness, fairness and sustainability is reflected in our first-class advice and services as well as in our products.

Perhaps this is why we have already received a number of awards such as

  • Austria's Leading Companies 2023 6th place nationwide

  • 1st in the "Austria's Leading Companies 2021 & 2022" competition (in the Burgenland classification in the "Internationally active companies" category)

  • Best family business in Burgenland 2021

to name just a few examples.


* Highest quality goes without saying for us.
