Mrs. Grivogiannis is the mother of Voula. Like her husband, she was very strict with their daughter. She was only seen in What a Night.

According to The Big Dance, she never went to a dance until she was sixteen.

During the events of What a Night, she appeared with her husband, at the police station. She and her husband were both furious to find out their daughter was involved with a friend who got caught shoplifting. She angrily told Voula that she had disgraced them.

Then during the event of Nothing to FearVoula mentioned that two months prior to the events of the episode, she had a successful operation at the hospital. Her daughter told this to L.D. Delacorte, as a way to get her to calm down and realize that not all people who go to to hospital always die.
