What her clients say...
As a professional performer with a bachelors in vocal performance, I have been so picky about vocal coaches. But Adrienne has really taken my performances to the next level.
Dezirae Gold, Denver artist
Adrienne helped me dig deep and find a voice I didn’t even know I had. Her teaching is going to help my Ted talk punch a hole in the sky!
Phil Jason Stone, Denver singer-songwriter
As a result of working with Adrienne my confidence is much greater and I can cover far more songs. If you could hear the difference in my voice a few months ago and now, you would understand why I called Adrienne "a miracle worker" after our last lesson.
Al Perry, UK singer-songwriter
From our very first lesson she made me feel so much more comfortable and confident in myself. She has helped me improve things I have struggled with for years in just a few sessions. She is a true gem and I feel fortunate to be working with her.
Ramara Chavez
I have been studying classical singing for around five years. After only one lesson, my band noticed a big difference in the sound and control I had over my voice, and now I am much happier with my more current sound!
I’ve learned to expand my range higher and lower with a pop tone that fits the music I do. Even the musicians I play with have noticed the difference, I’m singing with much more confidence.
Her coaching has enabled our child to be a member of a top choir at her high school as well as an annual soloist in her school shows. But more importantly, Adrienne has boosted our daughter’s confidence and given her the courage to take on new challenges above and beyond the stage.
I wanted someone who understands belting out rock or country at 2:00 am in a four-hour set. Someone who can improve your stage dynamics, help you capture an audience, build energy, and leave em’ wanting more. Not only has Adrienne delivered all that and more, but she is an absolute delight to work with.
