Voice Academy NYC Founder

Katarina Nolfe – Bio


“Teaching in New York City for twelve years, I have had quite a unique experience working with professionals, aspiring pros, amateurs or beginners of all ages, including architects, lawyers, brain surgeons, ambassadors, social workers, pilots and many more.  I love the diversity this provides every day and watching the joy which people share with their voices, while strengthening their inner voices. This is why I created Voice Academy NYC.”

Swedish-born Katarina Nolfe studied voice technique, song performance and music theory at New School University, and has worked as a singer, songwriter and vocal coach for the better part of the last two decades. She began performing as a child and through her teen years furthered her professional training, including at Kulturama, one of the most reputable music academies in Sweden.

Privately, Katarina studied voice under the world-renowned voice teachers Dr. William Riley and Don Lawrence (whose collective client base is a who’s who list such as, Celine Dion, Whitney Houston, Christina Aguilera, and Usher to name a but a few).

Prior to founding Voice Academy NYC in 2006, Katarina worked as a singer and songwriter and collaborated in recording studios with various musicians and producers such as Catalyst (Lady Gaga), Stargate (Katy Perry, Rihanna, Selena Gomez) and guitarist Willie Brown Jr (Alicia Keys). While coaching different singers in the studios of NYC, she discovered her gift for showing others the fundamentals of singing.

On September 27, 2017, Rachel Platten (Fight Song) joined Katarina and Rob as a surprise guest vocal coach as they jointly coached eight cancer survivors as part of Ford’s Warriors in Pink, More Good Days Tour.  (see more at AMNY.com and CBSNEWS.com)
