Your partner
Andreas Hassel
With a starting career in communication and marketing in advertising agencies, I specialised in digital since 1997 with the setting up of the first commercial websites in Switzerland and internationally. Since then, I am always on the edge of all the new possibilities in this exciting field. I am happy to share my knowledge within the mandates that I am entrusted with and in the schools where I teach.
