Mary Thomas is a recurring character on NBC series Frasier. She is portrayed by Kim Coles.


Mary worked at a bakery before joining a program to put regular people in different jobs. For this program, she fills in for Roz one week. In that time, she butts into the show too much, but listeners begin to like her advice. Eventually, she gets her own show with Frasier, but soon gets hired for her own show for another station. She gets rehired the next year on her own show, and co-hosts the Christmas parade with Frasier. Mary calls herself Dr. Mary, much to Frasier's dismay, as she is not a doctor (although she did graduate summa cum laude from the School of Hard Knocks).
