Meet Our Faculty


Craig & Tiffany Rinas


Craig and Tiffany Rinas met while attending a private Christian university in North Texas. Craig is a native of Owasso, while Tiffany has lived in a total of 9 states across the United States. Married and living in the Dallas/Ft. Worth area for the last 13 years, the couple have three lively young children.

Craig is a CERTIFIED FINANCIAL PLANNER™. Tiffany is a Licensed Professional Counselor and Adjunct Instructor in Counseling and Addiction courses at the collegiate level. Together they have a combined 20 years working in higher education.

Craig and Tiffany moved their family to the Owasso area at the end of 2015 for Craig to accept the position of Chief Financial Officer at Carpentree, Inc. The most difficult part of the moving process for the family was leaving behind their University-Model school. After prayerful consideration, they felt the Lord calling them to found Owasso Preparatory Academy as a developing University-Model school.

Our Teaching Staff

At Owasso Preparatory Academy our classroom teachers use valid teaching techniques to achieve curriculum goals and affect student learning, to integrate Biblical principles and a Christian philosophy of education throughout the curriculum, to partner with parents in the moral and academic development of each student, and to role model a consistent daily walk with Jesus Christ.
