As the originator of the Four Rooms of Change it is with great satisfaction that I have sold the ownership, copyright and all other intellectual rights to Wilson Utveckling AB. The cooperation agreement with the previous supplier regarding rights to certify in Four rooms of change has ended.
With contentment and inspiration I look forward to the developmental work that has now begun and will be offered through the new trademark Janssen's Model. I want to wish all the very best.

Roland Sjölin, CEO Svensk Fastighetsförmedling in Arboga, Köping and Kungsör

We noticed major improvements already after the initial introduction of the Four Rooms of Change theory. We are a small, tight-knit team that has taken on major challenges. Thanks to Janssen’s Model, we were able to navigate more safely and confidently through the changes we needed to make in all three locations where we operate. There’s no doubt that this was a definite factor in our success, helping us to focus on doing the right things in the right way.
