Workshop visits are by appointment only. Not to annoy you but I am also active as a teacher and professional trumpet player and sometimes I choose to work different hours. Generally workshop times are weekdays from 9.00-16.00 and saturdays 10.00-14.00. But please contact me first to plan a visit. I always will try to help you as fast as possible. Please contact me for your appointment and for the exact workshop address (in Wijk bij Duurstede, NL)
