Kids Voice-Over Lessons & Workshops

Through Online and In Person Workshops and Classes, Voice-Over Demo Prep, and Private Lessons, we have customized an extremely fun and freeing voiceover process which addresses each child’s needs and skill level, so they can freely express their voices and let go of self-consciousness.


Demos are essential in promoting your voice talent, either to agents or to casting directors and help you get work. We create a voice-over demo showcasing your best character voices, accompanied by music, and help you achieve the best results at auditions and book the job!

Sunday coached me privately for the Happy Madison/Netflix musical film called LEO starring Adam Sandler, Jason Alexander, Bill Burr, Cecily Strong. Our coaching session brought me so much confidence that I was able to bring my full, joyful self to the five-hour scratch record and book the role of Mrs. Salinas from my closet booth—I even got a song on the movie soundtrack! It was released on Thanksgiving and is Netflix’s biggest animated debut!

“I’ve been going to Sunday for her coaching services for the last three years. In that time Sunday has helped coach my voice work and given me general industry advice that has transformed my career. She’s thoughtful, astute, measured in her feedback, and is never afraid to offer some tough love when you need to hear it. This has helped me over come obstacles in all levels of my artistic career – leading me further than I could have gotten on my own. I cannot recommend her and her services enough.”
