The 2005 graduate held a master class with students who are planning to participate in the school's upcoming dessert cabaret.
Westfall provided feedback on their singing and presentation. She also shared valuable lessons she's learned along the way, including not to worry too much about conforming to what you think others expect from you.
"The biggest lesson I've learned is that all you can really do, and all that people really want, is to see you. Your true self. Just a genuine, authentic you," said Westfall.
Westfall says that all students can benefit from the confidence and self-esteem gained by performing in front of an audience.
Westfall currently lives in New York City and regularly performs jazz and cabaret at clubs in the city.
