Sandra is the office administrator at Hollyoaks High School. In September 2023, Goldie McQueen told Sally St. Claire that "Sandra from the office" has slept with half of the school's staff. Nana McQueen later told her that she played bingo with Sandra's mother Denise. In December 2023, Sandra attended the school's Christmas party and quickly got drunk, flirting with Beau Ramsey and Sally, who both turned her down.
