EXPERIENCE & EXPERTISE:
Meet Our Vocal Technicians
Joann C. Zajac & Zeffin Quinn Hollis
Joann C. Zajac has been teaching her precise and reliable method to singers for over forty years. As a Soprano, she has sung over fifty major operatic roles, her voice being described as "vocal perfection", "resilient and easeful", "master of the verismo chest voice declamation", "exciting high notes", "warm middle range" and "an extraordinary voice". She debuted as Mozart's "The Queen of the Night" in Die Zauberflote at the age of eighteen. As her voice matured, she took on the very challenging Lyrico-Spinto repertoire. Her portrayal of "Madama Butterfly" was called utterly perfect, with "heroic nobility, childlike vulnerability, and basic artistic integrity."
Unique to the industry today, Joann has earned a coveted reputation for providing a meticulous regimen that builds a strong and consistent vocal technique. She is known for unearthing talent; building voices from inception and guiding and managing her well trained singers through the inherent difficulties of a performing career. Students have traveled from as far as Hong Kong to work with this down to earth and practical technician and they encompass every genre including pop, musical theatre, and opera. Using her exceptional approach, her clients have garnered both critical and popular success working on Broadway, London's West End, and in opera houses all over the world. Her client list also includes recording artists and a long list of top celebrities.
