Testimonials
Working with Claire was exactly what I needed to bring my singing to the next level. I’ve struggled to use my head voice for decades, decades. She gave me concrete steps to not only strengthen my voice and extend my range, but also helped me identify what exactly I was struggling with in the first place.
Samuel, age 51, musical hobbyist and choral singer
Claire’s scheduling method is heaven-sent! She takes on virtual students as scheduling permits, which allows us to work around vacations, school plays, track season, etc. It’s allowed my daughters to study with so much flexibility and I don’t mind less time commuting to activities 🙂
Emmaline, mom to Campbell and Charlie, ages 13 and 11, learning to sing for fun!
Lots of teachers work on songs and call it a day, but Claire’s lessons are structured in such a way that it allows for so much growth. She identifies exactly where you are at, and gives you easy-to-use tools and vocal workouts to proceed to the next stage of your vocal development. And then she gives you new tools to move even further. It’s the best approach to technique that we have ever experienced, and it’s the quickest I’ve ever seen my daughter’s voice progress. Also, Claire is down-to-earth and quietly funny- we’ve loved working with her,
Natalia, mom to Maizee, age 18, student applying to college musical theater programs
The things I’ve discovered about myself as a singer have been revolutionary. I’ve learned so many incredible exercises and techniques to keep my voice feeling healthy and safe. I will never have enough words to encourage you to work with Claire in any way you can. I am infinitely beyond grateful.
Jenna, age 26, professional actor and singer
I learned more about how the voice works in my first month with Claire than I had in six years of voice lessons with another teacher. Her approach to technique is a game changer. I also struggle with performance anxiety and extreme nerves. She’s helped me discover what subconscious stories were holding me back from being my most creative self.
