Happy client of the vocal studio
Eva has taken me such a long way in just a short time. I’ve had friends not even recognize me on recordings. Working with her is, hands down, the best decision I’ve made in my career.

Happy client of the vocal studio
I was on a 3 month tour & came to Amber with a tired and worn out voice. She gave me some exercises to try and within 15 minutes I felt SOOO much better. Working with EVS, you'll not only get people who really know that they're doing but, you'll have people who really care & want you to succeed in your craft.

Amber Mogg Cathey

Vocal Health & Rehab Specialist
Mix Voice + Belt Training
Denver-In person + Online Worldwide

I’m a certified Vocal Rehabilitation Specialist, professional vocalist, and high-performance vocal coach with over 20 years of experience helping singers build strong, healthy voices they can count on—on stage, in the studio, and every day in between.

Before coaching full-time, I spent years performing at renowned venues, walking red carpets, and collaborating with incredible artists. Now, I bring that real-world insight into every session, helping singers train like artists, recover like athletes, and sing like themselves.

My approach blends evidence-based technique, vocal health expertise, and deep artistic development. I work with major and indie label artists, stage performers, singer-songwriters, and yes—even karaoke kings and queens—anyone ready to discover everything their voice can do.

A proud Berklee College of Music graduate and longtime Nashville industry pro, I’ve supported clients who’ve performed at festivals like Lollapalooza, Bonnaroo, CMA Fest, and Newport Folk Festival, and on shows like The Voice, American Idol, America’s Got Talent, The American Song Contest, and Good Morning America.

I specialize in vocal health and long-term vocal sustainability, often working alongside laryngologists and voice care teams to help singers recover from fatigue, illness, or injury and return to their craft stronger than ever.

Whether you’re preparing for a tour, navigating a tricky break, rebuilding your voice, or just ready to sing with more freedom—I’m here to help you sound and feel your absolute best.
