How we cycle 


The Child Assessment Group is run by an experienced team of international, highly educated, enthusiastic professional psychologists. Our team members come from countries around the world,

and offer services in multiple languages.


Hans Hogewind is the founder of the Child Assessment Group. He also works as a clinical  psychologist (restricted through the Individual Healthcare Professions Act). For two years he lived and worked in Shanghai with children from expatriate families. He received referrals from various international schools in Shanghai. Hans has extensive experience with diagnosis of children and adolescents, as well as supporting adolescents and families. Hans has an honors degree in Clinical Developmental Psychology and School Psychology from the University of Amsterdam. He is also a licenced Cognitive Behavioral Therapist ® (VGCT) and EMDR Europe practitioner ®. 


As a practising Psychologist, Hans' main motivation, is to help children and adolescents develop in a healthy and normal way. Although this might sound obvious many children are in fact facing challenges that prevent them from growing up in a happy, loving and supportive environment. Hans is able to determine the cause of the challenges and propose potential solutions that will help a child to be successful at both school and home. Hans sees it as his duty to support children and their parents explore struggles together, to find possible solutions to help the child cycle smoothly  through life.
