Welcome to the Mark T. Sheehan High School Website     

Mark T. Sheehan High School prides itself on meeting the academic, social, and emotional needs of our students. Sheehan is a comprehensive high school that offers a wide range of academic courses to prepare our students for post-secondary education and career interest and planning.  Our school counseling department provides students with guidance when choosing academic courses in order to prepare them for their future. Our school counselors and other support staff provide social and emotional supports to our students as well. The faculty is firmly committed to providing students with a positive school climate conducive to learning. Students are encouraged to seize every learning opportunity provided and become involved in a variety of extracurricular activities offered at our high school. We encourage parents to be involved in their student's learning experiences and extracurricular activities. Communication between parents and staff members provides a strong partnership to support our students. 

Go Sheehan Titans!
