 Principal Amy Hartjen

Mrs. Amy Hartjen

Welcome to the 2019-2020 school year! This is Mrs. Hartjen’s seventh year as Dysart High School’s principal, her ninth year at Dysart High School, and her twentieth year in the Dysart Unified School District.

This year, the Dysart staff will continue the traditions and excellence that embody Dysart High School. Mrs. Hartjen is excited to be the principal of a campus with so much history and pride. Demon PRIDE runs campus wide. The PRIDE mantra reflects the high expectations for both students and staff. Dysart High School is Future Focused.  Mrs. Hartjen wants to ensure that all students who attend Dysart High School are ready for the college or career of their choice. 

Dysart High School has a wide variety of programs to meet the needs of all students. From the strong academic programs (AP, Cambridge, and Dual Enrollment), to our signature programs (AVID, Automotive Technology, Photo Imaging, and ROTC) and arts programs, Dysart High School has opportunities for all students. In addition to academic programs, Dysart has twenty-two varsity athletic teams as well as many clubs and activities for students to join. Mrs. Hartjen passionately encourages all students to take advantage of all Dysart HS has to offer.

Dysart High School’s community wants all students to be successful, offering after-school tutoring on Tuesdays, Wednesdays, and Thursdays from 2:30 - 4:30 P.M. Mrs. Hartjen encourages all parents to reach out to your child’s teachers. If you have not already registered, all parents can access their student’s attendance and grades from the Infinite Campus Parent Portal. Please let Mrs. Hartjen and the administrative team know at any time what can be done to help your child have the best possible educational experience!

Mrs. Hartjen looks forward to seeing you on campus at Dysart High School events and activities!
