The Ascension Catholic Development and Alumni Relations Office works to promote good fellowship throughout an ever-widening community of alumni drawn from all walks of life. Bound together by the common experience of an extraordinary Catholic education, Ascension Catholic alumni form a community numbering more than 3000 men and women throughout the United States and around the globe. Together they represent the cultural, ethnic, religious affiliations, and abilities, talents and viewpoints of the global society that Ascension Catholic commits to serve.

Membership in the Alumni Association is automatic for all Ascension Catholic graduates. Alumni give their time and expertise to Ascension Catholic as members of the Board of Directors, as leaders of their classes (class agents), as coordinators of regional networks, and as ambassadors to prospective students and their families.

Alumni also support Ascension Catholic through their generous gifts to the Annual Fund, an unrestricted annual giving programs that are central to current operations. Contributions to the school are also made through periodic campaigns to increase AC's endowment, improve the physical plant and establish new educational initiatives; and through planned giving programs for bequest commitments and life income arrangements.
