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.

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.

Vocal Coaching and rehabilitation

As a professional vocalist and entertainer, I spent many years performing at well-known venues, walking red carpets, and working alongside incredible artists. For nearly two decades since then, I've dedicated my career to preparing professional artists for tours, guiding them through big studio sessions, and ensuring they shine at every performance.

My students have dubbed me "the voice whisperer" for my ability to uncover and solve the vocal obstacles that hold contemporary singers back from reaching their full potential. I train vocalists like the athletes you are, equipping you with the tools to feel confident, sound incredible, and stay performance-ready.

As a Certified Vocal Rehabilitation Specialist, I specialize in helping singers recover and restrengthen their voices after setbacks, whether from vocal fatigue, illness, or injury. I frequently collaborate with top voice care specialists to ensure comprehensive support throughout the recovery journey.

A proud Berklee College of Music alum with over 20 years of experience in the Nashville music industry, I now call Denver, CO, home. My clients have graced the stages of major festivals including Bonnaroo, Lollapalooza, CMA Fest, and the Newport Folk Festival. They've appeared on shows like The Voice, American Idol, America's Got Talent, and The American Song Contest, as well as performed on The Today Show and Good Morning America.

Whether you're a major or indie label artist, songwriter, stage performer, or simply looking to rule at karaoke, I'm passionate about helping you discover everything your voice can do.
