The affiliated Centurion Foundation supports charities with efficient operations, dedicated leadership, and measurable long-term impact, offering multiple giving levels to encourage sustained donations. Beneficiaries include Assistance League of Tucson, Candlelighters Childhood Cancer Foundation, Imago Dei Middle School, Grace Retreat Foster Care and Adoption Services, and various mentorship and healthcare programs. The Centurions of St. Mary's Hospital is a 501(c)(3) charitable organization founded in 1968.
