Meet Your Coaches!

Diane Divadi
Singer/Songwriter/Vocal Coach from Colardo, USA
Hello! I’m Diane Divadi,
I’m an experienced live performer in different styles including folk, rock, jazz and country. I started writing songs at 17 and love to record and produce my own music!
Before I met Kerri, I had already begun my vocal training. However, since working with Kerri and completing her Associate Coach Training Program, I have been opened up to a whole new level of powerfully effective vocal techniques which I’m thrilled to have the opportunity to pass onto you!
I’m super excited to work with you and help you find and develop your incredible potential!

I aim to uplift and inspire you to experience breakthroughs in your singing through a unique approach that teaches you to override your inner critic and fears, and step into the natural singer who already lives inside of you!
