Here at Arizona Tuition Organization (AZTO), our mission is simple, to make Christian Education affordable and accessible so that participating students can impact the world.

AZTO is a state certified School Tuition Organization (STO) that focuses on supporting Christian Education in Arizona.

  • Through Arizona’s Private School Tuition Tax Credit Program, AZTO has issued over $40 Million in tuition awards to students attending our partner schools.
  • AZTO was established in 2004.
  • AZTO currently partners with seven Christian Schools in Arizona.  We intentionally keep our partner school list short in order to provide quality personal service to our schools and participating families.
  • AZTO uniquely offers seven award cycles throughout the school year.
  • Arizona statute allows each STO to retain 10% of all donations for administrative fees.  AZTO has always operated with fiscal oversight and responsibility.  We issue a minimum of 92% of all donations received.

AZTO’s Team


Cassie Baker, President:

Cassie Baker joined Arizona Tuition Organization (AZTO) in 2019 and became Operations Director in 2026. She is passionate about helping Arizona families navigate the tax credit program and making it easier for children to access the education that best fits their needs.

Her connection to Arizona’s tax credit program began long before she joined the AZTO team. Shortly after the Arizona Tax Credit was introduced, Cassie and her husband enrolled their two children in private school. As she learned how to make the most of the program for her own family, she discovered a passion for helping other parents understand how tax credits can open doors to educational opportunities they may have thought were out of reach.

Before joining AZTO, Cassie taught at a private Christian school. During the years she was raising her children, she worked part-time in a variety of roles, including property management, office administration, and supporting her husband’s construction business. Those experiences gave her a well-rounded background in organization, customer service, and day-to-day operations that she now brings to her role at AZTO.

Cassie enjoys building relationships with families, schools, and donors and takes pride in helping ensure AZTO serves each of them with care, integrity, and excellence. She loves being part of an organization that helps make quality education more accessible for Arizona students.

Cassie and her husband have been married for many years and have two grown children and two beautiful granddaughters who keep life full of joy. When she’s not at AZTO, you’ll likely find her spending time with family or helping her husband with his construction business.
