Mark T. Sheehan High School

Thank you for visiting the Mark T. Sheehan High School website

As a comprehensive high school, Mark T. Sheehan offers a range of courses to meet students' academic needs and personal interests. The faculty is firmly committed to providing students a positive climate conducive to learning. Students are urged to seize every opportunity for learning that is available to them. Although we are proud of our accomplishments, we realize we are only as good as you, the student and parent, make us. Students are encouraged to be an active participant in a school-sponsored activity and parents are invited to become part of school life by joining one of our parent organizations, such as PTAC.
