Steven is the founder of the Dutch National Institute for Respiratory Physiology. His work focuses on understanding how breathing influences physical and emotional health. The institute explores breathing at a physiological level and makes this knowledge accessible to the general public.

Steven discovered Breathe, Sleep, Thrive while searching for resources that clearly explain the relationship between breathing, airway development, and long-term wellbeing in children. The book immediately aligned with his mission. He now frequently gifts it to young parents and to healthcare professionals.

In the Netherlands, Steven is developing projects that support healthy breathing habits from an early age. These include educating parents, teachers, and healthcare professionals to recognise signs of dysfunctional breathing, along with school-based breathing awareness initiatives.
