Nancy Zeltsman, Artistic Director


Nancy created ZMF to bring people together to share unforgettable, stimulating musical experiences in an atmosphere of support and camaraderie. She organizes ZMF throughout the year, aided by this talented team of assistants. Nancy selects a different faculty for each event and tailors the program to the specialties they wish to share--thereby creating a unique event each year for both new and repeat participants.
