“I’ve had the privilege of participating in two workshops with Cosi7 — one with David Lomelí and another with Annette Weber-Hussain. These workshops offer more than just the rare opportunity to audition for leading international casting directors; they also provide honest, immediate, and constructive feedback in a space that nurtures both artistic excellence and individual expression. A true gift for any singer committed to growth and authenticity in their craft.”

Her way of guiding — with such clarity, warmth, and passion — helped me rediscover my voice from a whole new perspective. I left the class not only with new tools, but with a renewed sense of purpose and a heart full of motivation to keep growing on this journey.”
