About Us:

Trinity High School, founded in 1918 by the Dominican Sisters of Sinsinawa Wisconsin, is a Catholic college-preparatory high school for young women. Trinity has earned an excellent reputation as a premier high school with a strong commitment to educating young women and preparing them for the future: intellectually, spiritually, socially, and morally. For over 96 years Trinity has been a cornerstone of the Oak Park-River Forest community. Trinity’s student body gives an average of over 16,000 hours of community service to the community.

Mission:

Trinity High School, in the Sinsinawa Dominican tradition, challenges young women to seek faith, knowledge and truth.

The school community guides young women in developing skills for lifelong learning, an ethic of care and the desire for excellence.

Each student is recognized as unique.  In a nurturing, Catholic, college preparatory environment, she is encouraged to become self-directed toward responsible participation in the global community in order to impact society, Church and family in the twenty-first century.
