Flagstaff High School interim principal Libby Miller had her interim tag removed Tuesday. The Flagstaff Unified School District Governing Board appointed Miller to full-time principal at their meeting. Miller was named interim principal back in December. Miller lived in Flagstaff in the past and recently returned to the city from Portland, Oregon. Both Miller and her husband are NAU alums. While in Portland she served in a variety of roles including principal, executive director of middle school programs and adjunct professor. She replaced David Roth, who stepped down as interim principal last semester. The motion to appoint Miller to full-time principal was approved unanimously.
