Harmony grew up in the Hudson Valley, where she began her acting training at the age of 11. She received her BA in Performing Arts from the University of New Hampshire. She then lived abroad in Prague, where she taught English and learned to drink beer. Her solo show, Human Fruit Bowl, written for Harmony by Andrea Kuchlewska, has taken her around the world to Prague, Amsterdam, Hong Kong and New Zealand. She is a recent graduate from the Maggie Flanigan Studios, and a proud member of Actors' Equity. Victorian Ditmas Park, in Brooklyn, has been her home base for almost a decade. She lives there with her painter husband.

I had the fortune of directing Harmony’s solo show and she inspired me every day with her imagination, thoughtfulness, and work ethic. Harmony is a deeply intelligent, generous and fearless talent who I hope to collaborate with again and again. If I had a theatre that had a resident company of actors she’d be the first one I’d call to ask to be a part of it. Harmony Stempel = The Real Deal
