With Rauch bringing so much talent to the character of Bernadette, it is hard to believe that just before she was cast as a regular in 2009, Rauch was contemplating her career as an actor. Not being able to make ends meet with having landed five jobs in five years that were not long-term or starring roles, Rauch faced an uphill journey when it came to having a career in the entertainment industry, as most aspiring actresses do.
