UUSM Musicians

Ryan Humphrey

Ryan Humphrey, Pianist

Ryan Humphrey started playing piano for UU services at a young age, having grown up attending the Greenville UU Fellowship in South Carolina (earliest remembered performance: either “The Circle of Life” or the theme from Jurassic Park). He helped found the women’s choir, Bon Voyage, at the UU Congregation of Columbia while in grad school, and prior to joining UUSM’s staff, he served for five years at First Unitarian Church of LA, first as accompanist and later as Director of Music. When not at a keyboard, Ryan mainly spends his time as an orchestrator, having worked on the scores to WandaVision, Frozen II, Ant-Man and the Wasp, Minions, and more. He dabbles in bagpipes and pipe organ, but always plays responsibly.

He holds degrees from De La Salle University – Manila, Berklee College of Music, and the USC Thornton School of Music. His first encounter with Unitarian Universalism was as a staff singer at First Church Boston in 2013-2014. He grew up in a multi-faith family, where, he says, “we practiced an odd mix of Catholicism, Buddhism, and traditional Chinese lore.”

He believes in music as advocacy, using the media as a platform for diversity, equity, inclusion, and justice. His compositions are focused on narratives and conversations surrounding immigration, racial justice, LGBTQ+ advocacy, and other social causes.
