Where You’ve Seen Me!

“Jillian is such a pleasure to work with. She is not only extremely talented, but a wonderful person who takes genuine care in the individuals around her. Jillian is always willing to take notes and applies them immediately. I would highly recommend her for any role she is right for!”

-Lauren Cosio Producing Artistic Director, San Antonio Broadway Theatre

"Jillian is a hard worker that is dedicated to her craft from start to finish. She handles the process very well by coming in prepared but also being open to criticism and direction throughout. She has shined in every role that I have cast her in and I always look forward to seeing her in any show."
