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.


Sara Velthuizen is a child psychologist who aims to support children and their families in questions of socioemotional wellbeing, academic achievement, and behavioral challenges. Sara earned a Master of Science degree in Child and Adolescent Psychology from Leiden University. Aside from her work at the Child Assessment Group, she also conducts research at Leiden University to obtain her PhD. Her research explores the effectiveness of new therapy methods for adolescents with Social Anxiety Disorder.

Sara was born in Sweden but grew up as a ‘Third Culture Kid,’ moving countries every so often with her parents and younger sister. A large chunk of this was spent in North Carolina in the United States, a place which still feels like home. Sara gained insight into the fantastic mind-opening and culturally enriching privileges of an international life; but also very real struggles which can accompany the life of an expat family. She is settled in the Netherlands together with her husband, their son, and their two dogs. Her primary goal in her work as a psychologist is provide families with the aid and counsel they need to continue toward a happy future.

Jet Sichterman is passionate about stimulating children’s social and emotional development, and highly motivated in finding out how she can help her clients to thrive.  Before starting her private practice called Expat Child Psychology, Jet worked with children in groups as well as on an individual basis in a variety of settings. She gained experience with assessments in a psychiatric facility for children in Oegstgeest. Jet graduated Cum Laude from a liberal arts & sciences program and has a degree in Child & Adolescent Psychology from Leiden University.

During the time she graduated from Leiden University, Jet offered 1-to-1 support to a young expat child with severe developmental delays in The Hague. She was disappointed to note  how hard it was for parents to find appropriate help for a non-Dutch speaking child and made it her personal goal to help international children who are struggling at home or at school.
