After graduating with a Masters degree at Leiden University in 1991, and before opening Dulanco, Gert-Jan Rodermond spent 6 years teaching Dutch as second language in the national school system. Dulanco opened its doors in 1999 and since then, more than 6,000 students have received language training from us.

The methods of instruction and course materials produced by Dulanco, are continually improving and always adapting to the changing needs of foreigners learning Dutch. This includes the evolving requirements of the NT2 and inburgerings courses.
