The St. Paul High School Alumnae Association, founded in 1925, has been an on-going means of maintaining contacts among alumnae and providing support for the school.

All graduates of the high school and those other students who attended who wish to maintain contact are considered members of the organization.

The Alumnae Association maintains a current database of all known addresses and emails.   A newsletter is sent (either by mail or email) three times a year (March, July, and October) to all known addresses.  Its publication and distribution is supported in large part by annual dues of $20.  Individual classes may obtain information from the database for reunion purposes.

Officers of the Alumnae Association are elected from among the membership and form the Alumnae Board, meeting monthly (except in the summer).  The principal or her delegate served as the Alumnae Moderator.  Until the Fall of 2013, the former principal, Sr. Maureen O'Brien, BVM '54, served as the Alumnae Moderator.

Several events are sponsored annually by the Alumnae Association, including the Mass and Luncheon honoring the Golden Belles in November, Candlelighting in December, the Mass for Deceased Alumnae in January, and the Fundraiser in April.

The annual fundraiser event raises monies to provide tuition assistance to children and grandchildren of alumnae enrolled in Catholic high schools, to support the BVM Sisters Retirement Fund, to offer assistance to a shelter for women and children, and to ensure the publication of the newsletter.
