Serena Alexander has taught Mathematics since 1987, originally in both maintained and independent senior schools. From 1990 she taught at St. Paul's School for Boys, where she was Head of Mathematics at their Preparatory School, Colet Court, before moving first to Newton Prep as Deputy Head and then to Devonshire House as Head. She is now an educational consultant and inspector but still helps to run mathematics conferences for prep school teachers. She has a passion for maths and expects her pupils to feel the same way. After a lesson or two with her, they normally do!
