From Cologne into the world

In 1993 Dipl.-Ing. Biologist Veit Hölzel founded the Hölzel Diagnostika Handels GmbH in the heart of Cologne and handed over the management to his daughter Anna Hölzel in 2012.

At Hölzel Diagnostika we reinvent ourselves every day!

Flexible, meticulous and fast

    This is how we make decisions

    This is how we advance our developments

But mainly:

    This is what customer service means to us



The Company

What we do is quite simple:

A part of our team deals with WHAT our customers need and WHERE we can get it. The other part deals with HOW the products are delivered and HOW they get to the customer. All of this extremely fast and at a fair price.

27 years in the market bring us a lot of experience and expertise in different business areas. Reliability, interest and commitment, but above all love for what we do, are our key to success.

This makes us a young, dynamic family business with a history of 27 years.

A solid foundation on which we can evolve, grow and reinvent ourselves every day.
