LaQuet Sharnell Pringle, TheoryWorks I Graduate

(Mrs. Doubtfire, Bring it On)

I’m swinging (in Mrs. Doubtfire) — and learning to read music has changed all of the game.


I am so thankful for TheoryWorks, because it's made this Broadway credit so much more enjoyable.

Tim Rogan,

TheoryWorks II Graduate

(Ever After - Alliance Theatre)

I am always looking for ways to improve in my profession, which is why I was thrilled to find the TheoryWorks course.


The skills I learned with Robert, are applied towards every audition that I go in for now.

Nicole Weitzman, TheoryWorks I & II Graduate

(Sister Act - John W. Engeman Theatre)

I'm 100x more confident. ...I've been able to look at callback materials and learn them so much quicker than in the past.


And, I did the entire course while on summer stock!
