The Jan Pustjens Foundation was founded in 2015. Jan Pustjens wanted to stimulate training opportunities for young talented percussionists. Recognizing talent and creating opportunities to develop this talent was his main motivation. The foundation wanted to continue this after his death by organizing annual master classes with the Conservatorium van Amsterdam as a central location. This annual Jan Pustjens Focus Day gave international masters and students the stage and the opportunity to highlight a subject or instrument. Students from all conservatories in the Netherlands would come together on this day.

Jan Pustjens, born on October 31 1946, was in life a gifted percussionist and a national and international music educator. Until his death he was also solo percussionist with the Royal Concertgebouw Orchestra. In addition to this he was professor of percussion and coordinator at the Conservatorium van Amsterdam where for decades he nurtured countless talented students, helping them with both their musical and personal development.
