Working together towards a vital metropolis

About Inholland

We educate independent, critical professionals and develop applied knowledge. Our efforts make a meaningful contribution to the inclusive world of tomorrow, with a focus on fostering a sustainable living environment and a resilient society. We do this across various locations throughout the Randstad and in various fields: from health to economy, and from technology to education.

With our education and practice-oriented research, we contribute to the vitality of the metropolitan area in which we live, work, and recreate, and to society as a whole. We focus on societal challenges and interdisciplinary collaboration, alongside professional organisations, governments, and social partners. Our approach is personal and accessible, driven by the belief that both success and setbacks are key to the development of professionals and individuals, for both teachers and students. Diversity is considered a strength in this process.
