Born and raised in Scottsdale, Arizona, Rebecca Alice Steiner has been performing since the age of four. During her first show in the ensemble of Bye Bye Birdie at the local Jewish Community Center, she missed her one cue, and fell in love with theater ever since.

Rebecca moved to Colorado in 2018 to attend the University of Northern Colorado. She received her Bachelor of Arts in Musical Theater and graduated in May of 2022. Following this, Rebecca has made the move to New York City! During her time at UNCo, Rebecca has performed in many mainstage musicals, virtual productions, and student-led performances. She also had the pleasure to be a Dance Captain and an Assistant Choreographer (Something Rotten, 2022). Rebecca was a part of one of UNCo's A Capella groups, 11th Avenue (2021 ICAA Quarter Finalists).

Outside of performing, Rebecca was a part of UNCo's Esports team, playing Counter Strike: Global Offensive. She found a love for playing video games during quarantine, and following this decided to become a streamer on Twitch in her free time. She is currently attempting to watch every season of Survivor.
