More than 40 years ago, our founder, Bart van Luijk, inspired us to put forth ideas that would change the learning industry.
Today, we remain deeply committed to using our knowledge, expertise, and resources to address global challenges and focus on topics that have an impact on some of the most underprivileged in society.
We want to live a world where people are aware of the environment, where we actively reduce single-use plastic waster and where everyone has access to safe and fresh drinking water.
DOOR supports safe drinking water and learning projects worldwide.
We foster long-term relationships with our global and local social-impact partners such as Plan International, the Bill & Melinda Gates Foundation, Unicef, and other local foundations.
We incorporate social impact as an integrated part of our business strategy and foster an atmosphere across the company, that values social impact both during and outside of the workday.
Our local offices organize community service days and volunteer activities, allowing our global teams to participate in mentoring and tutoring, awareness campaigns, and many other activities.
We create active consciousness regarding single-use plastic waste and support safe drinking water projects around the world.
