Rob Oliverio loves to help people find information. That’s why he became a librarian. If you ask him a question, he will do whatever he can to meet your need. In the meantime, he works behind the scenes to ensure that you can find books and other resources in the ACU Library’s catalog and on the shelf. He also offers instruction in how to do research and creates Pathfinders and handouts to empower you as an independent researcher. He strives to save you time and to lead you to success in your studies at ACU.

Rob is a Phoenix native who likes philosophy, theology, and church history most among his wide-ranging interests. After getting a solid, Biblically integrated education from Grace Christian High School, he obtained a B.A. in Integrative Studies with a Minor in Religious Studies from Arizona State University. His undergraduate education gave him a broad background in the liberal arts, especially philosophy. In fact, he even pursued graduate study in philosophy at Purdue University for a year before realizing his passion for librarianship. An internship at the Phoenix Seminary Library convinced Rob to seek an M.A. in Library and Information Science from the University of Arizona; he graduated in December 2014. Rob enjoys serving at Northwest Community Church and spending his free time with his wife Stefani (an ACU alumna) and their three children.

Tihesia was born and raised in New Jersey where she met and married her husband, Eric. They have five adult children living in different parts of the country. Tihesia is a lover of storytelling. She believes it is the most influential form of teaching, leadership, and evangelism. During her time on the mission field, she discovered the most powerful means of sharing the gospel began with one simple phrase, “Tell me your story,” after which she was able to share her story—a story of mercy and a testimony of grace.

Tihesia is a freelance writer pursuing a Bachelor of Arts in English with a concentration in Creative Writing. She is at her happiest when she is capturing beauty through photography which gets punctuated by her colorful poetry and prose. She is most inspired to write while on any outdoor adventure exploration, and she believes wilderness wandering produces the most wonderous wondering. Her mission in life is to love God and make His love known to everyone she encounters.

Her favorite scripture is Hosea 2:14 (NIV): “Therefore, I am now going to allure her; I will lead her into the wilderness and speak tenderly to her.”
