Our School

Welcome to MAS Integrated School, MASIS!


MASIS provides superior Preschool, Elementary Middle and High School education to students in the Western Region of Puerto Rico. It's conveniently located at PR #2 Bianca's Convention Center, in the beautiful Valley of Añasco.


Principal’s Welcome

 It is a great honor for me to introduce you a community of unique and creative learning. When visiting our school you will feel the warmth of a home and an atmosphere protected by family values. MASIS is synonym for family, and like all families we care for the most important human resource, our students and personnel, which is our reason to be. Success is no coincidence and that is why we evaluate, analyze, and make decisions daily based on data with the sole purpose to improve and achieve academic excellence.

In the words of ancient Greek Philosopher and Scientist Aristotle- “Excellence is an art won by training and habituation. We do not act rightly because we have virtue or excellence, but we rather have those because we have acted rightly. We are what we repeatedly do. Excellence, then, is not an act but a habit.”

We have succeeded in so many ways. As of last year, we have graduated dozens of students each currently enrolled in different colleges and universities in Puerto Rico and throughout the United States. We all embraced them and celebrated their success. One of the most powerful expressions of Excellency is seen through the various types of debates that take place in our classrooms. Students and teachers analyzing politics or finding a solution to a problem related to class subjects or issues affecting today’s society.

I encourage each one of you to embrace academic excellence, the kind of Excellency that begins to shape our children in the most powerful way, through the formation of positive thinking and empowerment. I want to emphasize and express my gratitude to the teachers of MASIS who have believed in Excellency in the classroom. As they prepare for class every morning and end an exhausting day, to return the next day with the same level of energy and commitment. I could not talk about Excellency without their true commitment, to each student that enters their classroom eager to learn new skills, and of course to each parent who believes in this family oriented school, MASIS. 


Mrs. Miriam Aviles Soto
