Her mission and core mandate is to educate and inspire lives, to build confidence and to unlock a person’s true singing potential. Regardless of any student’s background or faith, Adeline is absolutely committed to helping them reach their singing goals.

Unhealthy singing habits can ruin your voice permanently

In 2007, Adeline lost her ability to sing and even to speak. After ‘losing’ her upper vocal range, she sought medical help where they discovered that she had vocal polyps and nodes on her vocal folds (caused by serious acid reflux and frequent heavy usage of her voice).

A miracle happened: Her vocal fold polyps and nodules disappeared before surgery could even take place!

The initial trauma of losing her voice led her to the path of exploring healthy and holistic ways to sing. She is determined to help others avoid the painful experience of losing one’s voice and now places a strong emphasis on vocal health and voice recovery in every lesson.
