Ann Cantrell
Elementary Principal

I have a deep love for Glascock County and for GCCS.  In addition, I have always loved children and have a passion for helping them learn to be successful and happy in life and advocating for them to make sure they get a fair chance in life.  I have been so blessed to have a partner principal who shares my commitment to creating the best possible environment and education at GCCS.  Our main priority is to build relationships with our students and create connections with them so that they know they are loved and valued.  Our second priority is to provide a quality, top-notch education that that will equip our students to be successful in life.

Ms. Cantrell attended GCCS from kindergarten through twelfth grade, and is a 1991 graduate.  She attended Georgia College & State University where she earned a degree in middle grades education.  She earned a Master’s in school counseling from Augusta State University, and then a specialist in Education Leadership from Georgia College.  She began her career in education in Washington County, where she taught for five years before returning home to GCCS.  At GCCS, she has taught middle grades, served as a graduation coach, school counselor, and now as principal since 2018.

Ms. Cantrell and her husband Danny have been married since June 1991. They have three children- Aldon, Keri, and Allie, and two grandchildren- Chance and Annlyn.


Michael Costello
Middle/High Principal

Everything we do at Glascock County is about preparing our children for what comes next.  Whether that be the next unit of study, the next grade level, or the next challenge after graduating, our primary purpose is to provide our children with the knowledge and skills they will need to be successful.  We do that with our two core jobs each day:  (1) Make connections and build relationships with our children and (2) Provide quality instruction.

Mr. Costello was born in Atlanta, Georgia, and grew up in Jonesboro, Georgia.  He married Misty in June of 1998, and Mr. and Mrs. Costello have lived in Glascock County since 2007.  He earned a bachelor’s degree in English Literature from Georgia State University, and then a master’s degree in Middle Grades Education from Brenau University and a specialist’s degree in Educational Leadership from Columbus State University.

Mr. Costello has been the Principal of Glascock County Middle and High School since 2018.  Prior to becoming the principal, Mr. Costello taught English at Glascock County.  Before coming to Glascock County, Mr. Costello taught and coached at Thomson High School, Otwell Middle School, South Forsyth High School, and South Forsyth Middle.
