Marylou Flannery

Principal, Board Member

I originally became a member of the Salesian faculty serving in the Social Science Department, which resulted in me teaching every required course throughout my tenure. I became Department Chair after several years, in addition to coordinating the annual WASC accreditation process for the school. I was asked to assume various administrative duties in addition to teaching in 2009. Within two years, I became the Assistant Principal for Academics, and was appointed Principal in 2016, becoming the first female leader of Salesian College Preparatory. My personal interests include all things related to American History such as visiting museums, monuments, historic sites, or procuring artifacts or old books. I also love to be outdoors and work in the garden, walk my dog, or watch baseball and football games.
