In 1980 Ad started painting. After years of following various creative activities, he started two exclusive galleries in Amsterdam's Sonesta and Krasnapolsky hotels in 1983. He is best known for his tulip paintings. In 1990 Ad started to focus on making screen prints of his own paintings. He achieved such good quality that soon other artists also had their work printed by Ad. For example, he was Herman Brood's house printer for 12 years. Corneille, Jan Cremer, Rob Scholte, Shunyam, Peter Diem and many other artists also made frequent use of his expertise. After the disappearance of artists such as Herman Brood and Corneille, Ad saw the opportunity to specialize in a completely new technique, namely the creation of amazingly colored sculptures by means of CNC laser cutting and milling of various plastic materials.
