Stella starts her career at Pawtucket Brewery, in "The Blind Side", shortly following Opie's job termination. When Peter meets her, he is surprised at astute she is, but she explains that she knows how to read lips. Intrigued, Peter asks if her if without hearing, her other senses have been enhanced, such as if she can smell if he farts from across the room. She explains that she can't smell that, but that due to her extra reliance on vision, she can often notice subtle tells about a person, such as if they have farted, due to slight changes in their body movements. Peter then tries to give an example by uncontrollably spazming while he farts, to the point that she could have been legally blind and still seen it. When Quagmire meets her, he is inspired to hold a disabled ladies night at The Drunken Clam.
When Peter finds out that Stella gets cigarette breaks in "Secondhand Spoke", he takes up smoking so he too can have extra time from working.
Peter takes over a business trip to Chicago for Stella in "The Most Interesting Man in the World", while she's at the deaf games.
She attends Peter's roast in "Roasted Guy".
After Peter becomes deaf in "Peter's Def Jam", he turns to Stella for advice on how to cope with his condition.
She can be seen before Angela dismisses the employees early for Christmas in "Don't Be a Dickens At Christmas".
She is present during the millennial-meeting in "HttPete", when Hammer is introduced as her new superior. Hammer establishes a no-swearing policy, which annoys everyone, including Stella. Stella signs a profanity at him, thinking she can get away with it, but he understands sign language and punishes her, by making her wash her hands with soap.
