Gaby taught me to believe in my sound as an interpreter. She also helped me to improve my guitar skills. Now I feel ten times more confident performing. She encourages me to do the repertoire I love and nailed it.

I learned with Gaby, to love my voice, the uniqueness sound I have, and how finding a repertoire needs to be adapted to me and not the opposite. Now, every time I'm on the stage, I feel way more comfortable and start to enjoy the rush of the audience.

Gaby gave me the confidence I was looking for in a teacher. 
Her mantra of focusing on the process and keep trying, helped me to achieve my goals.
