J. Sebastian Fabál

Dramatist, Educator,

Executive Director 

Sebastian Fabál (he/him/his) is an award-winning musical theatre writer, educator, dramaturg, and now executive director of Chicago's Underscore Theatre Company.


A Cuban-American from Miami, Florida, he moved to Chicago after 7 years in New York City where he received his MFA in Musical Theatre Writing from NYU’s Tisch School of the Arts. While living in NYC, Sebastian's 9-5 career began with overseeing various music and grand publishing rights for some of the stage's most beloved artists through the Rodgers & Hammerstein and Boosey & Hawkes catalogs.


As a composer, lyricist, and bookwriter, Sebastian's work explores the complexities of the second-generation Latinx experience, specifically the weird identity spectrum of neither being American or Cuban enough to be immediately accepted in either community.


Since moving to Chicago 7 years ago, he's worked as a musical dramaturg with The Second City, taught several musical writing classes through Chicago Dramatists, the Dramatists Guild, and Porchlight Music Theatre, and has co-founded the Chicago Musical Theatre Collective. Sebastian was most recently the Sr. Director of Customer Experience at, the marketplace for musicians, where he oversaw the global Sales and Customer Services teams through an acquisition by Etsy in the fall of 2019.


Husband and father to two adorable spitfires bound to take over the world.
