Mr. Greg Miller and Mrs. Pam Miller founded Challenge Charter School in 1996 with a shared passion for putting kids first in education.

Mrs. Miller served on the Paradise Valley Unified District Governing Board for 8 years including one as President of the Board as well as the United Parent Council president representing thousands of parents in PVUSD. In addition, she was an active and dedicated volunteer inside of her own children’s classrooms and campuses, as well as serving on committees and boards to further kids’ causes. She has an extensive business background, having owned more than one business in her early career, and was in Finance when the couple’s shared passion and activism in education led them to travel a different road and make the dream of putting kids first in education a reality at Challenge Charter School.

Mrs. Miller has held several important administrative positions at CCS including: Administrative Manager/Vice Principal and Creative Programs Director, serves as the Executive Director of the non-profit company, and both Vice President and current President of the corporate board.


Mr. Greg Miller was a Senior Level Manager in the Civil Engineering and Land Planning business for over 25 years. Having been very successful in the corporate world, he said about founding CCS, “Nothing I accomplished in those years ever felt as good as a hug from a Kindergartner that is excited to be at school that day.” Mr. Miller held a short term high school math and science special education teaching position, in addition to extensive education volunteerism like Mrs. Miller. Mr. Greg Miller was appointed by Governor Jan Brewer to serve on the Arizona State Board of Education in 2010 and reappointed in March, 2014 as the Boards’ Vice President for two terms and President for two terms.

At CCS, Mr. Miller served as Principal, the CEO of the non-profit company, and President of its Corporate Board before his passing in October 2017.

The Millers’ passion for putting kids first in education has had a local, state, and national impact on education reform. They have been recognized for these contributions locally and nationally. Read more about their accomplishments here..
