One Voice. Two Paths.

"If you love One Voice the way I do, then you want to know absolutely everything there is to know about it. When you are taking lessons, you’re getting information that applies to you and your goals. The Certification Program presents information that you maybe would never have gotten to otherwise in the context of a lesson. As a singer, it has helped me tremendously. But even more than that, it is such a gift to be able to share One Voice with singers and help lead them on their vocal journey. I truly believe with all my heart that the world needs One Voice. It is such valuable information that can revolutionize the world of singing, and the beginning of that is the Certification Program."

- Alex Zeto (Certified One Voice Master)

"The Certification Program prepared me so well to teach One Voice and help singers build their voices, but I didn’t expect it to affect me the way it did when it comes to leadership. As a teacher, director, choreographer, etc.... I feel I have such

unique skills when it comes to communicating and leading people to a

particular goal. And so much of that is because of the training I went

through with One Voice.... Going through the Certification Program has

given me a confidence that I didn’t have before, and that confidence

spills over in all aspects of my life."

One Voice Master Coach - Alex Zeto

The crescendo of certification continues on and on.

"There is more to learn, more to share, and more

to explore - we’d be honored to have you be a

part of it. Expanding the reach of One Voice

is really important to us, and we’d love to have you

join our mission of getting it heard around the world."

- Michael Maresca (creator of One Voice)

Maintaining Certification

Listed as Certified Coach

on One Voice website.


Having earned the elite status of becoming a Certified One Voice Coach isn't the end of your journey, it's just the beginning. You are now part of a close knit community of other certified coaches who help each other sharpen their teaching skills, remain open-minded, and stay current with industry trends.

We do this in three ways.

This is an intense 5 to 7 day program covering everything you need to successfully and gracefully teach One Voice in a private session. For 8hrs a day you'll be along side other passionate, open-minded individuals learning about One Voice history, theories, techniques, philosophies, and our teaching practices. The whole week culminates to a singular moment when you deliver your very first One Voice private session to a student you’ve never worked with before!

{Cue Celebration}

If you've chosen the path of teaching for One Voice your fun continues. Our next step together will be learning how to deliver an effortless and seamless online session - which is something we’re quite good at. Next we'll dive into what it takes to make the online experience feel warm and comfortable both in and out of a session. Our work will again bring us to another first - delivering a One Voice private session online!

{Cue Celebration}







Every month you’ll be required to deliver and receive a session from/to another Certified One Voice Coach. This rotates every month, so you’ll be working with and receiving sessions from a different coach each month.

Keeping you in the loop on all the new discoveries, tools, concepts, exercises, and research uncovered that year. Delivered online by our most seasoned One Voice Masters and Coaches.

Twice a year you will have a session observed by a One Voice Master who will offer you feedback to ensure your teaching skills continue to uphold the high standards of the One Voice community.


Yearly fee for maintaining certification is due before certification anniversary.

"I had no idea how meaningful it would be to my future.

It’s one of those moments in life that I look back on, and I

don’t really remember how I got there, but I am grateful

every single day that I did. I couldn’t ever have predicted what

that week would do for my voice, my confidence, and my life."

- Alex Zeto

Becoming a Certified One Voice Coach is more than just a piece of paper. It's more than 5-7 days of intense training... It's a life long commitment to the community of coaches, our philosophies, and the people we work with. We have no plans of slowing down, and our desire to understand the human voice will continue on. We think One Voice will change the world of singing, and we hope you'll join us.
