About Us

Welcome to Southern Tier Catholic School (STCS) and Archbishop Walsh Academy (Walsh) - the only private Catholic school in the Southern Tier to offer Montessori, Elementary and High School educational experiences for your child. Merged in 2010, the two private schools are located on one campus, with STCS offering Montessori for 3-5 year olds and kindergarten through eighth grade, while Walsh serves ninth through twelfth grade and offers the prestigious International Baccalaureate Diploma Programme to juniors and seniors. We are one school, located in the heart of Olean, N.Y. 

Think Differently about the value of attending a private Catholic school.

  • We empower and enable the development of your child to fully realize his or her capabilities.
  • We provide an academically rigorous program that highlights a classical liberal arts education.
  • We encourage spiritual thought and critical moral thinking leading to moral action.
  • Students have the opportunity to participate in the arts, engage in creative service projects and participate in strong sports programs.
  • We do all of this with dedicated faculty and staff who can offer individualized attention through small class sizes grounded in a Franciscan heritage that welcomes students of all faith traditions.
