Arizona’s Catholic Tuition Support Organization (CTSO) has been blessed with a significant corporate gift from CenturyLink. Gary Gunther, Vice President and General Manager for Northern and Southern Arizona and Guillermo Figueroa, Market Development Manager for CenturyLink presented a $200,000 Corporate check to CTSO Executive Director Gracie Quiroz and the Most Reverend Gerald Kicanas, D. D. Bishop of Tucson.  Gunther stated that among the community issues in which CenturyLink “walks the talk,” education is “number one.” “Our support of CTSO stems from our desire to partner with organizations that are already in the classroom doing the important work of providing education to our community.”

What We Do

Welcome to Arizona's Catholic Tuition Support Organization at the Diocese of Tucson (CTSO). CTSO has provided students with the opportunity for an education centered in moral, academic and faith-filled values. To date, CTSO has awarded tuition scholarships to more than 30,000 students. All made possible through the generous contributions of the public and corporate community, the Private School Tuition Tax Credit and the Corporate Tuition Tax Credit.

School Tuition Organizations cannot award, restrict or reserve scholarships solely based upon a donor's recommendation. Taxpayers may not claim a tax credit if the taxpayer agrees to swap donations with another taxpayer to benefit either taxpayer's own dependent.
