Her theatrical work also earned acclaim, including a Drama-Logue award in 1990 for her performance in Jean Genet’s The Maids at the Mark Taper Forum.
In the late 1990s, O’Brien transitioned to coaching, contributing her expertise to Sunset Beach, Passions, and ultimately holding a long-standing role as acting coach on Days of Our Lives until her retirement in 2022. Her mentorship shaped generations of actors, leaving a lasting legacy in daytime television.
