Roz is one of Will's colleagues at Doucette & Stein.
She has a friendly acquaintanceship with Will, although she becomes bitter and resentful towards him when Mr. Stein shows favoritism towards him over the other employees, accusing him of being a "kiss-ass". 
In season 8, Roz is up for partner against Will and Gary. When her husband Glenn reveals that Roz is pregnant, she is fired by Margot who believes that mothers are less productive in the workplace, despite Roz's protestations that she "might not keep it". 
- She is a fan of The Practice.
