About GAHS

Welcome to Greencastle-Antrim High School, an active, vibrant learning community for students in grades nine through twelve.

It's a whole new world at this level as students continue to learn and grow and as they begin to make preparations for life beyond high school.

We provide a wide range of educational experiences and guidance as we continue to put Children First and expose each student to as many opportunities for their futures as we can.

A Message from our Principal

As principal of Greencastle-Antrim High School, I am honored to work with our district’s students. They truly are top-notch and take full advantage of the variety of opportunities we offer. Many of our students earn college credits through our Early-to-College and College Academy programs. Others participate in internships through our School-to-Work program. Students seeking a career in a technical field will benefit from our GAHS STEAM Program, as well as our partnership with Career Tech (FCCTC). In addition, our students excel in music, arts and athletics, but most impressive, they truly display outstanding character, supporting one another through times of tragedy and times of triumph.

Greencastle-Antrim High School has enjoyed a rich history of quality education at this location since 1960.
