Working with Ariel was an amazing experience. She has a knack for getting the best out of her clients because she truly cares about their success and growth. My realm as a sports broadcaster is unique, she did the research to understand my craft, used her expertise as a singing and speaking coach, and formulated a custom approach to help me improve

Ariel Thiermann, the vocal and creative coach is captivating, her instruction is illuminating, and most of all, she is inspirational-eliciting self-expression through voice and song. Never have I seen my children flourish the way they have around Ariel. Not only are they budding singer/songwriters, but ultimately, empowered human-beings.

 I don’t know where to begin... I’m completely addicted to my weekly sessions with Ariel! What started as just a nice way to spend a little more time singing has become my favorite thing I do for myself. She has helped me to transform my voice, reaching notes I never dreamed I’d be able to hit. She has encouraged me to perform (something I didn’t have any thought of doing when I started working with her). She constantly pushes me to try new material and challenges me to improve. I leave each session feeling energized and renewed. I cannot say enough about how much I love my voice lessons with Ariel!

I’ve improved so much since working with Ariel and recommend her to anyone looking for someone who is knowledgeable yet fun to work wikth at the same time!

"Working with Ariel has been delightful. Our work together has helped me progress as a singer, songwriter and performer. She brings a genuine love of teaching and the creative process to every session and that makes it enjoyable and productive. She understands the connection between the physical act of singing with the emotional and spiritual growth of the artist. Whether a seasoned performer or a beginner Ariel intuitively understands what you need and will always tailor her coaching to the individual needs of the singer/artist.- Steven Graves, Santa Cruz, CA
