Holly Valiska Gregory — Producer, Director, Writer

About

A career built by ear.

From Emmy-winning live-action to bilingual pop songs for Dora — the throughline is always story, character, and sound. I cast, direct, write, produce. I've worked on everything from documentary to animation. I love this field because the work keeps changing shape while the job stays the same: make it good enough that a kid wants to hit play again.

I tell great stories and make great music for kids.

I've showrun original comedy and adventure podcasts, developed adaptations of beloved book series, cast and directed voice-over for some of the most recognized characters in children's television, and produced original music for multiple series and albums. Whatever the format, I bring the same things to set or to the studio: energy, industry knowledge, creativity, and a great pair of sneakers.

Definition of sneaker (ˈsnē-kər): any shoe that feels comfy and bouncy and allows for fake tap-dancing, salsa twists, and subway commutes. Mr. Rogers, my mentor, was right: kids deserve someone ready to play, so change your shoes and get ready to move.
