Learning to Love, Loving to Learn since 1962
“Every memory of Seisen is wonderful which includes the Sisters, my friends, teachers, staff, classes, participating in extracurricular activities, and being involved at school. What they all have in common is that as a child and student, I knew that I belonged at Seisen. As students, we always accepted each other even for our differences in culture, religion, and opinions. We didn’t judge and were never judged. I’m grateful to my parents for choosing Seisen for me since Seisen is a big part of who I am today."
As an international school graduate and father of two boys , I have gotten to know Seisen and its environment from many angles throughout the years. I share many precious memories with Seisen graduates and have been blessed to get to know the faculty and staff after enrolling both my sons in Seisen kindergarten. My wife and I wanted my eldest son to experience a Montessori education before St.Mary’s and my youngest son is currently following in his footsteps. I was delighted to see both my sons enjoy and learn so much in Seisen’s unique environment and am grateful to share this special experience with them. Seisen’s education system had always impressed me as a student, and now as a father, I feel the curriculum has kept evolving and enhancing year after year. Needless to say, I have utmost faith in Seisen’s highly trained and experienced teachers who continue to provide a priceless education to all.
We love Seisen and are proud to be a part of the greater Seisen family!
