Child Assessment Group

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) and manager at a Mental Health Clinic in Hoofddorp, North Holland. 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 practitiorner ®. 

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.


In her professional approach Marije Assink focuses on the overall development of children and adolescents. She is action and solution-oriented. Marije always works in collaboration with the client system and other specialists within her network. Most challenges experienced by her clients usually do not occur only within one context, such as the home environment or at school. She believes structural solutions are found in a broad and tailor-made approach, aimed to support the child in all areas of life.

Marije works as an independent Educational Psychologist and has a private practice in Leiden. After completing her internship abroad (South Africa) in 2004, she returns to complete her studies at the Faculty of Social Sciences in Groningen. In combination with various positions within (international/special) education and mental health care, Marije starts a private practice in June 2009. She helps children, adolescents and young adults between the ages of 0 and 23, their parents, family and school with questions about upbringing, learning development, behavior and the effect of life changes.

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.

Katie Reindl is a California, U.S.A licensed marriage and family therapist.  Since 2007 Katie has been providing mental health counseling services to children ages 6 and up, individual adults, couples and families from a variety of cultural socioeconomic status, and linguistic backgrounds in various capacities. In 2013, Katie started a clinical counseling practice providing individual, group and family counseling services to English-speaking expat children, adolescents, individual adults and families in Amsterdam.  As an expatriate herself, Katie is inspired to utilize her professional clinical experience and educational background as a family therapist to provide counseling services in The Netherlands.  The goal of her practice is centered around assisting expatriates through the transition of living abroad as well as developing coping tools, strategies and helping individuals come up with solutions necessary to thrive in their environment.  Her mission is to help lessen the angst and confusion that often accompanies a move, while helping individuals adapt to their new surroundings.  Together, Katie helps to facilitate a rewarding journey towards creating positive changes in her client’s lives.

Katie is also passionate about helping children feel successful at school which allows them to be life long learners.  Her focus is on improving the child’s academic learning environment, which at times is hindered by the following: cognitive, academic, behavioral, and social/emotional functioning.  Katie is inspired to help children who are showing signs and symptoms of struggles at home and/or at school find potential recommendations for the child to help alleviate the symptoms.  Katie is driven to help identity the “missing pieces to the puzzle” that is detouring the child from feeling successful in his/her home and school environment.  Along with her team members at Child Assessment Group, Katie coordinates care between the client’s school and home environments to help bring continuity of care that allows the client to thrive in his/her school and home environment.

Laura van der Belt is very motivated in her work with children and parents. Besides her work for the Child Assessment Group, she works as a psychologist at a Mental Health Clinic for children and adolescents in Hoorn, North Holland. She grew up in a bilingual (and bicultural) family, since her mother is Italian and her father is Dutch. Growing up with both languages and cultures, has made her aware of the important influence of culture on the education and development of a child. She is eager to apply her professional knowledge in helping children reach their full potential, working together with their parents.
