Mark Cox

Hi, I’m Mark Cox — singer, actor, vocal coach, connection coach, and team builder. My passion is helping people find their voice — through singing, speaking, performing, or simply learning to express what’s most true in them.

With a background in music and counseling, I founded the School of SING! and currently serve as assistant music director of the Cantata Singers. I also work with teams and organizations helping them build the kind of genuine connection that makes everything else work better.

At the heart of all of it is the same belief: that finding your voice — and being willing to use it — is one of the most powerful things a person can do.

Jondra Harmon

Hi, I’m Jondra Harmon, a mezzo-soprano and vocal coach. I’m a teacher that believes in the power of strong technique. Through detailed study, we will discover your true voice and learn how to use the mechanism optimally for amplified and unamplified singing styles. We will lean into a holistic approach, focusing on mindset, vocal health, true artistry, and creating a collaborative learning environment between student and teacher.

The working, twenty-first century vocalist is versatile, flexible, and expected to use their voice facilely in many styles, including classical, musical theater, gospel, pop, or jazz. I foster an environment of experimental and playful learning, allowing the student to thrive and know their voice in any style.
