Holy Trinity High School, a diverse community of learners centered on Catholic teachings and traditions, nurtures faith development, celebrates individual gifts, promotes Christian service and active citizenship, teaches for life long learning and global perspective, and challenges students to aspire to excellence.

Since its inception in 1984, Holy Trinity High School has established itself as one of the finest academic high schools in Edmonton. As students and staff prepare for the school year 2011 - 2012, the motto "To Care, To Serve and To Share" continues to be the foundation of our school's philosophy. Holy Trinity High School attends to the academic, physical and spiritual needs of the students in the Millwoods Community. The environment of mutual respect, tolerance, and celebrating differences allows students and staff to carry Christ's message beyond the walls of the school.
Attached to the Millwoods Recreation Centre, our school has excelled in many different areas. Diploma examination results and the number of Rutherford Scholarships awarded to grade twelve's have been most impressive over the years; the same can be said in the area of athletics where in excess of three dozen city championships have been earned. In addition to thriving art and music departments, we enjoy an extremely strong drama department which sponsors an annual year play. Students act, sing, and dance to sold out audiences in late March every year.
