Specific & clear in her instructions, open to feedback, patient and encouraging, courteous and respectful - not to mention a great singer. Looking forward to future lessons with Deborah.

I was pretty nervous about taking a singing lesson, as it's something I've never done in my life. I'm so thankful I got connected to Deborah. She's a fantastic teacher and taught me so much about how our body works to produce sounds when singing and what I am doing. From the first lesson I was already given helpful tips and ways to practice things on my own! I'm looking forward to more lessons with Deborah.

She was great in showing me singing techniques and really understanding how to use your body for different styles of both singing and acting!

My daughter has so far two lessons with Deborah and she always comes out smiling. She said she really likes her. I believe it is because she makes her relaxed enough to share with her the kind of music she enjoys.

Deborah is amazing with kids, turns boring theory, singing techniques and practicing into fun games. Kept my high energy 8yo daughter engaged for a whole hour!
