He studied improvisation with Cor Kee, French baroque music with Marie Claire Alain and was with Gaston Litaize for a two year period specializing in the works of Ceasar Franck and Olivier Messiaen.

After that he played recitals all over Europe and the United States on the most important organs.

He was appointed professor at the Den Haag conservatorium after completing his studies. Many of his pupils have glittering careers.
