Every year, St. Francis High School holds a fundraising event called POSH ("Preserving Our Scholastic Heritage"). This even brings current parents, parents of graduates, alumni and friends of SFHS together to raise money for the school.

POSH is presently being held on the St. Francis campus. The event included a Silent Auction, a SFHS Marketplace, Entertainment, Cocktails and Dinner. A Grand Raffle is also held.  Sponsorship opportunities are available to assist with underwriting the general expenses of the event.

Proceeds from the POSH even generally go to support scholarship, as well as project-based needs.
