Sister Mary Ann Luby, who had served the District’s homeless population for the last 27 years, died at her home last night after an very short battle with cancer. She was 70. You don’t look very hard to realize just how amazing a woman Sister Mary Ann was; in a short eulogy, Patty Mullahy Fugere of the Washington Legal Clinic for the Homeless, where Sister Mary Ann had worked in an outreach capacity since 1995, summarized that she “challenged us to be faithful to the people whom we serve.” Sister Mary Ann’s passing will be a big loss for the D.C. homeless advocacy community, especially in a time when budget concerns have some suggesting cuts to the city’s safety net programs.
