"When I entered the freshmen hallway on that first day of school, I entered an environment I had never expected, I had entered into a second family." -Kristina, Somersworth



St. Thomas Aquinas High School admits students of any race, color, national and ethnic origin to all the rights, privileges, programs, and activities generally accorded or made available to students at the school.  It does not discriminate on the basis of race, color, national and ethnic origin in administration of its educational policies, admissions policies, scholarship and loan programs, and athletic and other school-administered programs. 


We are pleased to have Rebecca on the door step of St Thomas Aquinas.  Her older sisters' successes in their first years of college has been great confirmation that their education at STA was worth their effort and our dollars.  STA undeniably prepared our daughters with a strong academic foundation, but also supported and molded their personal growth in character and faith. They entered college with a strong sense of self, an understanding of their place in the world, and a drive to contribute to whatever community they find themselves a part of. We look forward to Rebecca growing into her adult-self with these same cornerstones of life. -Mrs. Jeannie Spear, Mother
