Experience positive change
with MdB Behavior Consultancy
"Through understanding behavior, we can make longlasting change"
MdB is moving countries
In August 2025 my family and I will move, and my consultancy will come with me.
But not to worry, the only thing that will change is the registration from Danish to Dutch.
I will continue all my services, and for those in Denmark and other countries I will resume sessions online after a month of settling in. See you again soon from the Netherlands!

A warm welcome
