All instructors that work for GMAT Amsterdam are experts in the field of the GMAT exam. They have a background in mathematics, physics, management, economics, business or the English language and know how to teach. All instructors know the study materials for the GMAT well and know how to help when students don’t understand certain questions or topics.

Meet our instructors:


Jasper Reinders

My name is Jasper Reinders and I am 31 years old. I studied mathematics and physics at the University of Amsterdam, where I also worked as a teacher for seminars. I am the head instructor of GMAT Amsterdam and developed the study material for all of the different courses. I have been deepening my knowledge about the GMAT in order to be able to help others with this often difficult test. Helping people understand what they first did not understand makes me feel satisfied. We at GMAT Amsterdam are experts in the GMAT; not only in content but also in learning strategies and preparations. With our experience in accompanying students to the GMAT, we learned how to help GMAT participants with their specific preparations.


Iris Huisman

My name is Iris Huisman and I’m 23 years old. I hold a Bachelor’s in Language and Communication and a Master’s in Intercultural Communication. At GMAT Amsterdam, I’m responsible for the contact with clients, organisation of the courses, the development of new ideas and the quality guarantee. I enjoy informing people about the GMAT and giving them personal advice that suits their aims and situation. Knowing that we help people to achieve their best possible GMAT score is what makes my work satisfying to me.


Sybren Woudstra

My name is Sybren Woudstra and I am 31 years old. I have  worked as a GMAT Verbal teacher at GMAT Amsterdam for three years. Because of my interest in language – both structure and content – I like to explain the construction of sentences and texts to others. Helping students find their paths in their career is satisfying for me. That is why I like working for GMAT Amsterdam. Even though the study material stays the same for every course, the different questions and examples from students keep encouraging me to make the study material insightful in different ways. That’s challenging and very interesting! Beside working as a teacher at GMAT Amsterdam, I teach Dutch classes to expats and help international students in their preparations for studying in the Netherlands.


Marco Stoffelen

My name is Marco Stoffelen and I am 30 years old. I hold a Master’s degree in physics and have worked as a teacher at GMAT Amsterdam for four years. I also work as a mathematics and physics teacher at an international school in Amsterdam.  What I like about teaching is the appreciation you get when you help students understand a problem. That moment when they start understanding what I am trying to explain satisfies me.


Rens Dudink

My name is Rens Dudink. I am 22 years old and I studied mathematics. I have worked as a teacher at GMAT Amsterdam for 2,5 years. Because of my background in mathematics, I feel this job suits me very well. Every student has struggles with a different part of the GMAT, and this makes the classes very diverse. I find it challenging to help as many students as possible.


Max de Lorijn

My name is Max de Lorijn and I am 24 years old.  I hold a Bachelor’s and Master’s degree in economics, both of which I took at the University of Amsterdam. I also took an extra minor in economics and business at the Lund University in Sweden. I work as a business mathematics instructor at Bijlespartner and I teach mathematics, microeconomics and accounting at Studygroup. I’ve worked as a GMAT teacher at GMAT Amsterdam for six months. I like to solve complex problems by finding the most efficient solution. The appreciation I get when I clarify complex problems, that ‘aha’ moment, is truly satisfying!


Kasper Nicholas

My name is Kasper Nicholas and I am 23 years old. I studied Liberal Arts and Science at Amsterdam University College and I am currently taking a Pre-Master’s program in Business Analytics. I worked as a tutor at De Vrije School Den Haag and as a performance analyst at Kas Bank. Because of my affinity with numbers and my bilingual education, I thought being a teacher at GMAT Amsterdam would suit me well. Mathematics has always been interesting to me and I took many math courses during my Bachelor’s program. I like working as a GMAT instructor because the groups of students who follow the courses are very diverse, which makes each class different. Because we work in small groups, the students feel free to ask questions which ensures interaction and a nice ambiance.

The way GMAT teaches you to think about mathematics and develop your mathematical intuition is something I enjoy teaching.

Before I started working at GMAT Amsterdam, I did an internship in Mexico City, where I worked for LeasePlan Mexico. I teach Verbal courses as well as Quantitative courses at GMAT Amsterdam. The most fun aspect of teaching for me is that every lesson is different. The students have a big impact on the course so you never know what to expect.

I hold a Bachelor’s degree in English and Spanish linguistics and a Master’s degree in translation studies (Dutch/ English), both of which I took at VU Amsterdam.

I find it exciting to stand in front of a classroom and find the most effective ways to explain problems. I like to see students being interactive and helping each other in order to develop their skills during a course. And it is always nice to get a message from a student saying that they got the GMAT score they aimed for.


Steyn Gardien

My name is Steyn Gardien and I am a 23-year-old student. I am currently taking a Master’s degree in Business Information Management at the Erasmus University in Rotterdam.

I find it exciting to find out different ways to explain the study material to the students.

Sarah Lovera Rivas

My name is Sarah Lovera Rivas, I’m 21 years old and I’m currently getting my Bachelor’s in Economics, Psychology and Philosophy at University College Utrecht. After exchange programs and internships in 5 different countries, I started to look for a new challenge and decided to apply to Master’s programs abroad. To my surprise, the GMAT formed a crucial part of the application process for almost every university I looked at, so I started working towards my target score. Luckily, the hard work paid off and my score of 720 got me accepted with scholarships into all my target schools. For GMAT, a good preparation is key! This is why I started teaching at GMAT Amsterdam: I know the GMAT preparation process can be a struggle and I want to help others get the most out of themselves and get the scores they deserve!
