Alex Rubin grew up in South Jersey, just outside of Philadelphia. She has been involved in Theatre her entire life, first as a performer, then as a director and designer, and finally as a playwright and lyricist. After graduating from high school, Alex decided to forego college for a year and move to New York City where she landed an apprenticeship in the marketing and PR department at The New Victory Theater, New York's leading theater for kids and families. She also worked at Starbucks during that time and can make a mean cappuccino.​
 

Alex attended Hofstra University where she found her way to directing after debuting her original one act Yet to be Titled which eventually flourished into a full length musical entitled At the Edge. During her time at Hofstra, Alex wrote and directed over 30 productions on campus and several more professionally in film, television, and theatre.

As a member of the BMI Musical Theatre Workshop and the Dramatists Guild, Alex has had the thrill of seeing her plays, musicals, and songs performed in New York City, Houston, Los Angeles, London, Canada, and more. She was a 2012 SPACE on Ryder Farm resident, 2013/14 Big Vision Empty Wallet Playwriting Fellow, 2017 National Winter Playwrights Retreat resident, second rounder at Austin Film Festival, and the first place winner of the 85th Annual Writers Digest Award in Playwriting. She holds an MFA from the University of Southern California's John Wells Division for Film & TV Writing for which she was an Annenberg Graduate Fellow.
