Co-Founder & Program Director


Krystal Diaz


Krystal comes from three generations of influential musicians and performers in Hong Kong. She started performing on stage at the age of 8 years old and became a world-class certified vocal coach in 2008 (Speech Level Singing Level 3, Institute for Vocal Advancement Level 4).

Since then she has been featured on TV and radio several times as a top vocal coach and has trained many of the most celebrated voices coming from Asia, including international singer/songwriter Bishop Briggs, internationally acclaimed actors Donnie Yen (Ip Man; Star Wars Story: Rogue One; Mulan) and Tang Wei (Lust, Caution; Blackhat), as well as top HK singer, Joey Yung, to name but a few. 

She is also a sought after vocal consultant for top music producers and record labels such as Universal Music and EEG.

As a singer, Krystal has performed at many of Hong Kong's top venues, including the Hong Kong Cultural Centre, the Kowloon Exhibition Centre, and the Hong Kong Coliseum, and in October 2019, her debut album, Reflections, will be releasing under the New Century Workshop production company.
