Rebecca Hill

Chief of Staff

I graduated from the ASU College of Public Programs with a B.A. in print journalism in 1997.

After completing a Research internship at the Arizona House of Representatives, I chose to stay and work in the public policy space and eventually spent the next 25 years researching, developing, and advocating for public policies-primarily in K-12 education.

I have worked for a Superintendent of Public Instruction, a Governor, and ran a consulting business for 15 years. The bulk of my consulting was in the area of education innovation and funding.

When I’m not geeking out on education policy, I love to hike, travel, spent time with family, and find new restaurants. I am also known to be a bit obsessed with Sun Devil athletics. I am thrilled to be on the ASU Prep team!
