One2change is the consulting firm that develops resilient people and organizations through teaching them how to effectively realize changes as well as changing the way people and organizations learn and develop. Through connection and boldness we achieve sustainable results

One2change was founded in 2017 by Naomi van Loon. After a successful career with large international as well as smaller organizations, she wanted to stand on her own two feet. With her broad expertise and passion for development, she started following her dream.

For our clients we work together with internal and external consultants. In that sense we can deploy the right combination of knowledge and experience for every challenge. Together we work on increasing the learning and change capacity of people and organizations in order to develop resilience, which leads to improved organizational results.
