She joined Rooster Teeth as a full-time staff member in February 2016 as a Website Content Manager. She appeared in Podcast 417 to eat a pancake Gus made, and ended up sticking around for the rest of the podcast sitting in Burnie's chair (even when Burnie showed up), with her dog Rupert harassing the hosts for pancakes. Her appearance was well-received enough that she began making semi-regular appearances on the podcast, occasionally with Rupert joining her.
Although Becca has been a good friend of the Rooster Teeth production crew since 2003, Burnie intended to allow other women to audition for the role of Sister despite the pressure of the other members. Two other girls auditioned for the role before Becca was given her chance, but when she began auditioning, the team made something of a joke out of the audition, slipping in lines of dialog that got increasingly more vulgar to see how far she would go before refusing to do a line. Upon realizing she had no such limits, Becca was cast as Sister and the role was rewritten as a far more promiscuous character to fit with the lines she had read in the audition.
She is married and has a daughter, who coincidentally, was born in the same day that Sister first appeared on Red vs. Blue. During Extra Life 2017, Becca revealed she is again pregnant, and due in May 2018.
Her Rooster Teeth profile is Becca.
