Initially producing figurative works, mainly landscapes, nature morte, ballet dancers and clowns, he ended up with contemporary and abstract paintings influenced by modern Dutch painters such as Van Wordragen, Van Iersel en Cremer.
A complete change of style was caused by his beloved brothers sudden death in 2001. He, his brother Toon, was also a talented teacher in high school. In 2002 Nol dedicated an exhibition to him called Education.
Being married to his lovely wife Maria, he got two daughters who also work with people, the one being a school teacher and the other being a psychologist, Nol started painting from childrens drawings which brought him and his paintings back to basics in both colour and style. Painting is for Nol an experience comparable to complete relaxation and bliss. His works of art are to be found in various private collections, galleries, firms and companies such as banks.
