help and guidance.”

“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.”
Becky Shrimpton
