manufacturer, diabetes expert, family business

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 past decades. We are an Austrian family-owned company, headquartered in Marz in Burgenland, Austria. With the Wellion brand, we have developed into a global manufacturer and specialist. Not only in the field of diabetes, but also increasingly in the areas of health and well-being. The driving force is our high quality standards, as summarized in our mission statement.


Our aim is to make life easier for patients and partners.
Through innovative ideas, advice and service.


We are ideally positioned in our core competencies. We are manufacturer of diabetes and healthcare products for people under our brand Wellion, and for animals unter our brand WellionVet. For our partner companies, we develop marketing and sales concepts and manufacture their products (OEM production). In addition, we offer logistics and administrative services as required.


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
