Mrs. Quick is Sabrina's slightly daffy Algebra teacher during Seasons 2,- 4, replacing Mr. Pool as the teacher Sabrina's closest to, becoming involved in the messes Sabrina causes with her magic.

When Sabrina catches Finger Flu in "Finger Lickin' Flu," Mrs. Quick, who is trying to learn to assert herself with Sabrina's help, catches Sabrina's magic and accidentally turns Mr. Kraft into a chimp.

Mrs. Quick reveals a talent for quiz shows and puzzles in "The Long and Winding Shortcut," so Sabrina tries to get Mrs. Quick to work out the family secret for her.
