About Chrissellene Petropoulos

and the Arts


Chrissellene G. Petropoulos is an internationally renowned opera singer.  After facing vocal challenges of her own, she set out to discover the science behind vocal production.  Over the course of several years, she developed a science-based method to build and repair voices. Her passion lies in sharing her knowledge with students and providing opportunities for musicians, actors, singers, dancers, and performers.


While she currently runs the Vocal Mastery Academy, Inc., Ms. Petropoulos, ever looking to the future, created the Allegri International Foundation, Inc. (501c3) to ensure that her science based system and studio will continue to benefit artists forever.



She built a performing arts venue for three purposes: 

  • To educate performers.

  • To provide a venue for performing and fundraising.

  • To continue her legacy for future generations.
