Carin Serrano – den Breejen teaches IGCSE Chemistry to Year 10 and 11. She was born in Enschede and obtained a MSc degree in Chemical Engineering from the University of Twente. Before moving into teaching, she worked in Coatings Research and Development as well as Human Resources. She spent 17 years in England and the USA, where she worked as an AP Chemistry tutor as well as substitute teacher. Upon moving back to The Netherlands in 2022, she started teaching at IST and College Zuid and she obtained her first-degree teaching licence in July of 2024. She loves travelling, running, singing and showing students the different aspects of chemistry: exciting (sometimes explosive!) and interesting but also logical and organised.
