Alumni Association of the Roman Catholic High School of Philadelphia
Cahillites stay connected to Broad & Vine.
Roman Catholic High School’s students and alumni are called Cahillites, after the school’s founder, Thomas E. Cahill. That’s where Cahillite.com gets its name. Since 1915, the Alumni Association has kept Roman’s graduates connected to the school at Broad and Vine and to one another.
Cahillite.com is the official website of the Alumni Association of the Roman Catholic High School of Philadelphia, a 501(c)(3) nonprofit organization (EIN 23-1872983) separate from the school. Street address: 301 N. Broad St., Philadelphia, PA 19107.
About the Association
Who we are
Philadelphia merchant Thomas E. Cahill left most of his fortune to found a free Catholic high school for boys. Roman Catholic High School opened at Broad and Vine in 1890, and its graduates are still called Cahillites in his honor.
Alumni formed the Alumni Association in 1915, for the school’s 25th anniversary. Today it is a 501(c)(3) nonprofit organization with its own board, separate from the school. In its 2024–25 fiscal year, the Association granted $1.16 million to Roman for student scholarships and tuition.
To foster relations with alumni of Roman Catholic High School; to promote the interests and general welfare of Roman Catholic High School; to maintain and advance Catholic education and academic excellence.
