DOOR History

On one side there are things that are known,
on the other side there are things that are unknown.
In between there are always DOORs.

(William Blake 1757-1827)

DOOR History

The company was founded over 30 years ago, in 1981, in the Netherlands. 11 Years later DOOR entered the international marketplace. The growth of the business was based on the franchising model with the "golden rule" of highly competent trainers, coaches and consultants applying their business experience to the challenges and opportunities of their clients.

Today, the company provides training, coaching, consulting, e-learning and assessments in over 90 countries around the world. The DOOR network has nearly 1000 trainers, consultants and coaches, of whom over half have been associated with the company for more than 10 years. Their experience spans many business sectors and is applied to the design and development of our training solutions. As a consequence of this experience, our customers benefit through improved business results.
