What Your Voice Has Been Missing

Many singers have worked with coaches who are great at one thing. Great at technique but can't help you find your sound. Great at performance but can't tell you why your voice does what it does. Great at vocal health but have never actually lived in the commercial music world.

At Amber Mogg Cathey Voice it's different. We bring real technique, genuine vocal health expertise and deep artistic development together - specifically for contemporary singers who want to sound and perform at their absolute best.

From the Vocal Pro Collective and one-on-one coaching to targeted courses - there's a way to work with us that fits exactly where you are right now.

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.

Amber is THE vocal coach to go to in the Denver area. Not only is she a very highly skilled singer herself, but she understands the voice better than anyone I’ve worked with. We’ve only had a few sessions but I’ve learned more in that short time than all 10+ years I’ve been in the singing/show business. It’s incredibly helpful to have a vocal coach who is also a vocal rehabilitation coach and if you’ve been in this business you know how important that can be. If you are a singer, you simply must get your coaching from Amber. It’s an investment you will not regret!

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 her, 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 Berklee College of Music graduate who has spent decades doing one thing: becoming the best possible coach for contemporary singers. Pop, rock, R&B, folk, country, singer-songwriter - not classical, not a little bit of everything. The real world of commercial music, from the ground up.

I'm a certified Vocal Rehabilitation Specialist - meaning I don't just help you sound better, I help you understand what's actually happening in your voice, fix what isn't working and build something that lasts. I’ve supported singers performing at major festivals like Lollapalooza, Bonnaroo, CMA Fest, and Newport Folk Festival; on national television including The Voice, American Idol, America’s Got Talent, The American Song Contest, and Good Morning America; and on national Broadway tours.

And I bring all of that into every session.

No shame. No mystery. Just real training that builds real confidence - and leaves you sounding more like yourself every single time.

Whether you’re preparing for a tour, navigating a vocal setback, rebuilding your voice, or ready to finally understand all  your voice is capable of - I'm here. Let's make it happen.
