  • Angel N., Class of 2023

    “Through SMLS’s unique opportunities available to students, I was able to join SWAT 77 [the school’s robotics team] in Grade 8. This allowed me to learn more about and pursue my interest in STEMR. I have also found ways to become involved in the school community with the numerous leadership opportunities offered to students.”

  • Bisma B., Class of 2008

    “Once you become a Millie, you are welcomed into a family, a community, and a network with deep and loving traditions…When I was a new entrepreneur, this community supported me. It provided mentorship from other alumnae who had been in business long before me. This community provided me with a network that I could rely on and a foundation to help me thrive.”

  • Claire B. Class of 2013

    “SMLS is a community which offers all girls life-changing experiences to grow, build self-confidence, and to thrive academically. I started as a student in kindergarten and stayed all the way through to the end of Grade 12. SMLS was a safe place for me growing up, where I could be my true self and where I was welcomed warmly by all staff.”

  • Eva L, Class of 2022

    “As a Senior School student, I had designated advisor times when I could meet with advisor teachers and have individual, one-on-one conversations. This is how I learned firsthand that, whenever I need help, there would always be someone in the SMLS community who could give me guidance.”

  • Jessica M., Class of 2023

    “As I enter into my final year of high school…I get to think back now and count all of the things I love about SMLS. Things like our small class sizes, which mean we get the help and academic attention we deserve. I have always found my teachers to be caring and supportive and I can approach them with any questions or issues I may have. All the teachers and faculty members are amazing and all have the same goal of making students more successful.”

  • Katie D., Class of 2025

    "In my time at St. Mildred’s-Lightbourn School, I have had so many fantastic experiences. I never feel scared to share my voice in the classroom, and I love being surrounded by courageous and confident women. I am constantly pushed out of my comfort zone, and exposed to leadership and learning opportunities. Across my extracurricular activities, I have made connections with students across the grades, and have built strong relationships with many of my teachers.”

  • Melanie P., Class of 2018

    "SMLS prepares students to succeed in their post-secondary experiences and life beyond the pillars, through academic challenges such as AP courses, support such as extra help lessons and, most importantly, talented and dedicated teachers and the peers who surround you. I feel excited for what the future holds.”

  • Miranda P., Class of 2003

    "I was taught that my ideas and voice mattered. I was taught to care for myself and others, both at school and in my community. We practised the joy that comes from supporting and lifting up other women, and it was so easy and natural to do.”

  • Paisley H. Class of 2023

    “The impact that SMLS has had on me is substantial. SMLS Has both amazing opportunities as well as excellent staff that have helped guide me towards achieving my goals.” 

  • Sena Y., Class of 2022
