The personal touch.
That's what sets Voices Only apart from the field.

Recording. Album production. Arranging.
Private masterclasses. ICCA coaching.

Whatever we're helping you with, Voices Only strives to work WITH you at every step of the process. We're not done until you're completely satisfied. These are our core directives:


We love COLLABORATING with groups and artists to find their true sound and together create something magical. We don't want to do this by ourselves and we don't want to put the burden on you. It's all about working together to create great art.

We believe HONESTY is one of the most important things in life and in business. From day one, we're open with you about everything we're doing together, and we'll keep you in the loop and answer any questions along the way. There's enough stress and anxiety in the world, who needs more?

We're not satisfied until you've reached maximum SATISFACTION. That's our #1 goal, assuring you're happy with what we've provided and what you've gotten from us.

We absolutely LOVE a cappella, love making music, and love working with our friends and clients to provide an amazing experience and an amazing product.
