Ms. Hetty Flanery - Humphreys HS Assistant Principal

Mrs. Flanery is excited and proud to join the HHS Blackhawk family. She was born in South Korea and raised in California when her family immigrated at the age of four. Mrs. Flanery has over 18 years in education beginning at the Marine Corps Air Station El Toro Child Development Center. She entered DoDEA in 2000 as a fifth-grade teacher at Amelia Earhart Intermediate School on Kadena Air Base, Okinawa, Japan. She has worked and served military-connected students and their families in Japan and Germany, as well as Korea; teaching kindergarten, second grade and fifth grade. She believes in delivering excellent instruction for students who make the sacrifice of moving with their active-duty family to duty stations across the globe.

Mrs. Flanery’s commitment to school excellence and student achievement includes her most recent position as the Assistant Principal at Humphreys Central Elementary School where she successfully served over 800 students and their families. Additionally, Mrs. Flanery served as the Pacific West District Accountability and Assessment Instructional System Specialist for five years. In this capacity, her continuous school improvement endeavors supported the 12 Pacific West schools and DoDEA’s vision to deliver excellence in education for every student, every day, everywhere. She maintains a focus on assisting students to succeed as global citizens and leaders.

Mrs. Flanery’s undergraduate studies were completed at the University of California Irvine, where she received a Bachelor of Arts in History and Teacher Credentials in the Cross-Cultural Academic Development Program. Mrs. Flanery received her Master of Education from the University of California at Los Angeles, and her Master of Education Administration from Grand Canyon University.

While Mrs. Flanery’s professional passion is pursuing excellent instruction and advocating for students’ academic and non-academic needs, Mrs. Flanery is also passionate about God and family. She enjoys Christmas throughout the year and loves cooking for her family and friends, music, running, and quilting. Her son, who has attended DoDEA schools since kindergarten, has provided her a rich insight into the lives and needs of DoDEA students. From her son she has learned to put “relationship before rigor, grace before grades, patience before programs, and love before lessons.” Thanks to her retired Marine husband, she has had the opportunity to travel around the world as a military family member committed to life-long learning and support for all students and their families.
