During McGuire’s tenure, Trinity’s institutional accreditation was affirmed in 1996 and 2006 by the Middle States Commission on Higher Education; in 2006 the Visiting Team report noted, “Transformed over the last two decades by dramatic changes and courageous and deliberate embracing of ‘paradigm shift,’ the University has remained remarkably faithful to its rich tradition, the founding vision of the Sisters of Notre Dame de Namur: the special commitment to women, to the primacy of the liberal arts and to the Catholic intellectual, moral and social justice tradition.” During McGuire’s presidency, Trinity also secured accreditation from the National Council for Accreditation for Teacher Education (NCATE) for its education programs and from the Commission on Collegiate Nursing Education (CCNE) for Trinity’s RN-to-BSN program.
In 2000, D. C. Mayor Anthony Williams and the D.C. Financial Control Board appointed President McGuire to a special term on the Education Advisory Committee overseeing the D.C. Public Schools.
In 2007 the Greater Washington Board of Trade honored McGuire as the “Leader of the Years,” one of only six women ever to receive this annual award from this regional business organization.
She has received honors and awards from the Girl Scouts of the Nation's Capital, Gallaudet University, the Ignatian Solidarity Network,[4] Ward 5 in Washington, and other civic and educational organizations.
She writes and speaks on a wide variety of topics concerning higher education and her articles have appeared in The Wall Street Journal, The Washington Post, The Baltimore Sun, Trusteeship, the LA Times and other publications.
