Matthijs’ first known drawings are from ’64, when he wasn’t even two years old. These ‘early works’ already clearly showed that he was trained by his father, the artist and art teacher Jos Stam. Matthijs mainly works in commission. He specializes in portraits, city-views and other large, storytelling paintings in which a lot is revealed about the commissioners (and often also about their family and environment).
His work is part of many collections, all over the world.
In 1999 Matthijs founded Galerie Atelier Stam, at the Prinsengracht in Amsterdam. Here he creates and exhibits art together with a small but fine circle of other – Dutch and international – artists.
