Huntsman Advanced Materials (Switzerland) GmbH (Chemie)

Mr. van Wyk provides high quality English classes that I was looking forward to come to every single week.
I did not only enjoy the atmosphere in the class, but also seeing my progression as time went on.
He is very engaging with the customers to make sure nobody in class gets left behind.
I can highly recommend Mr. van Wyk to anybody who pursues optimizing.
