Jo Brook is a Montana native and NYC-based Hard of Hearing actor, musician, writer, and disability advocate. 

Jo grew up making folk and bluegrass music with her parents and siblings in Montana, discovering her deep love of performing long before she knew it could become a career. She spent a decade attending the Montana Fiddle Camp, where she immersed herself in Old-Time, Texas-style, Celtic, Cajun, and Canadian fiddle styles and traditions, learning from legendary musicians including April Verch, Buddy Spicher, Bobby Hicks, Alice Gerard, Brad Leftwich, and Calvin Vollrath.

Following in her sister Brittany's footsteps (and mostly on a whim), Jo decided to pursue a degree in theatre. Turns out, it was a pretty lucky whim. 

For the past 15 years, Jo has worked professionally as an actor and musician, performing regionally, throughout New York City, and internationally.

Some of her favorite credits include playing the wonderfully quirky, Hard of Hearing astronomer Henrietta Levitt in Lauren Gunderson’s masterpiece of a play Silent Sky at Asolo Repertory Theatre in 2023 and appearing on Hulu's hidden-camera series What Would You Do? where she tricked a lot of nice and innocent people. 

As a late-deafened adult, Jo continues to explore the strange world of being an actor/musician with profound hearing loss, and she has found an unexpected passion for disability advocacy. With grant funding and staffing support from the Center for Hearing & Communication, Jo helped found a support group in Manhattan for artists who identify as Deaf, Hard of Hearing, or have hearing loss. In 2025, she received the Sheldon Williams Advocacy and Leadership Award in recognition of her work. She also wrote the feature essay for American Theatre magazine, "Hard of Hearing Shouldn't Be This Hard."

In April 2026, Jo premiered her solo show, Back Float: A Very Hard of Hearing, d/Deaf-ish, Bluegrass-Forward Solo Show, at Emerging Artists Theatre's Spark Festival. Stay tuned for its 2027 remount!

Jo is also the co-founder of the all-female bluegrass collective The Snowy Mountain Sisters, which she started with her sister Brittany in 2015. Since then, they've performed throughout New York City, across the United States, and internationally.
