Welcome from our General Director

Hortensia PrietoAlong with several other faculty and staff members, I have been part of San Roberto's community for a long time now.  I've been a mom, a teacher, a Principal, Campus Director, and now I have the honor to be ISR's General Director.  

I've witnessed how in a 35 year period, a small local school blossomed into an international, yet student centered institution, were strong academics and values are fundamental.

This didn't happen by chance; every teacher hired, every investment, every decision taken, has happened thinking in the wellbeing and growth of our students; but the key factor of our success is the unconditional support and involvement of our families.  Together, we can empower our students with the academic, physical and emotional matureness they need to grow up as confident learners ready to take any challenge their future brings.

You will find at San Roberto a very unique combination of state of the art education, global environment and technology, blended with traditions and values.  Your child will have the opportunity to excel in a welcoming community where he will be cherished and nurtured.

You are welcome to join us.

Hortensia Prieto, M.Ed.

General Director
