More than lab medicine – committed to blazing trails, driving development, and achieving more

Does history foretell the future?

In 1953, Georges Viollier, MD founds the Viollier laboratory in Basel, at home in the basement.

On the way back from school, his four children use their bicycles to pick up the sample material from the physicians' milk boxes and bring it home to the lab.

Basel’s first bike messenger was born.

A story of three generations

With pioneering spirit, the pursuit of perfection and the care of the details Georges Viollier, MD put the foundation of our way of thinking and working. We remain faithful to these values for generations.

Marc-André Viollier, MD, Anne-Françoise Viollier, MD, Edouard H. Viollier, MD, the second generation, takes over the management of the company in stages, while soon the third generation during school vacancies is assembling customer packages with preanalytics. Today, Dominic Viollier, lic. oec. HSG and Natalie Krebser-Viollier, lic. phil. psychologist, the children of CEO Edouard H. Viollier, MD, are also committed in the company. Both daughters of Anne-Françoise Viollier, MD are in the final stages of their professional training as medical doctors.

Continuity as a success factor

In 1986, the foundation was laid for the first two buildings of the state-of-the-art laboratory center in Switzerland, which went into operation in 1988 and 1989. A third lab building was added to the center in 2014. It took a total of 28 years from planning to completion of these three lab buildings.
